Description

An all-in-one bidirectional water treatment device and method in which the membrane filtration process of a ceramic separator and the ozone oxidation process are combined

The present invention relates to an integrated bidirectional water treatment device, and more particularly, an integrated bidirectional water treatment device and It's about the way.

Since separation membranes were used for experiments on osmosis in 1748, material separation using separation membranes began for the first time in 1829 through studies on the diffusion of gases and liquids in solid materials.

These membranes are classified into organic membranes, inorganic membranes, metal membranes, and asymmetric membranes according to their physical properties. There is this.

Here, the ceramic separator is known to have high physical durability in extreme conditions such as pH, pressure, temperature, etc., is resistant to relatively high-concentration chemical cleaning, and is recently used in various fields because of the ease of maintenance compared to the high molecular polymer separator.

Specifically, since the ceramic separator is hydrophilic and can be back-washed, stable operation with high flux is possible. Also, since the membrane surface has a high negative charge, bacteria, algae, MLSS, and microorganisms that are negatively charged in water It has the advantage of being easy to remove contaminants such as produced high molecular substances (TEP) and oil. In addition, such a ceramic separator can improve the removal rate of dissolved organic matter (DOC) such as low molecular weight algal-derived organic matter (AOM) even if only a low concentration of coagulant is injected, and also by adding low concentration of sodium hypochlorite during backwashing. It is possible to control the biofouling before growth, and thus, it is possible to reduce membrane contamination. Due to these advantages, an immersion type membrane filtration process using a ceramic separator is in the spotlight.

Figure 1a is a view showing a ceramic separator tower configured in the form of a ceramic separator according to the prior art, Figure 1b is a view for explaining the concept of the immersion membrane filtration process according to the prior art.

As shown in FIG. 1A, a plurality of ceramic separators 20a are stacked to form a ceramic separator module 20b, and a plurality of these ceramic separator modules 20b are stacked to form a ceramic separator tower 20. Such a ceramic membrane tower 20 may be built in the submerged membrane filtration unit 10 shown in FIG. 1B .

At this time, the treated water outlet 21 and sprinkler pipe 22 are provided on the upper part of the ceramic membrane tower 20 built in the submerged membrane filtration unit 10, and the air diffuser pipe 23 is connected to the lower part, so that the ceramic membrane A branch pipe (23a) for diffusion is located at the lower part of the tower (20). A raw water inlet pump 11 and a raw water inlet valve are provided in the submerged membrane filtration unit 10 in which the ceramic separation membrane tower 20 is located, so that raw water is introduced.

In the case of the membrane filtration process using the submerged membrane filtration unit 10 in which the ceramic separator 20a is disposed in an immersion type, the filtration process and the cleaning process are alternately and continuously performed. For example, after the 55-minute filtration process, a 5-minute washing process is performed, and again, the 55-minute filtration process, the 5-minute washing process, etc. are continuously performed in the order.

First, the filtration process using the submerged membrane filtering unit 10 in which the ceramic separation membrane 20a is disposed in an immersion type will be described in detail. Raw water such as wastewater to be treated passes through the raw water inlet valve by the raw water inlet pump 11 and flows into the submerged membrane filtration unit 10. At this time, the raw water is subjected to membrane filtration in the submerged membrane filtration unit 10, Sludge is formed.

Specifically, as pressure is applied to the ceramic membrane 20a by the suction filtration pump 41, the treated water is extracted from the ceramic membrane tower 20 through the treated water outlet 21, and the extracted treated water operates the filtration valve. It passes through and is collected in the treatment water tank 40 .

A disinfectant material such as chlorine is additionally added to the treated water collected in the treatment water tank 40 from the chlorine injection unit 60, and then discharged or reused. At this time, as other substances capable of disinfection other than chlorine, ozone or manganese dioxide may be used, and the chlorine injection unit 60 may be an ozone injection unit or a manganese dioxide injection unit.

The sludge separated from the submerged membrane filtration unit 10 is collected at the bottom of the submerged membrane filtration unit 10 along the bottom inclined surface 12, and then passes through the sludge discharge valve by the sludge inflow pump 13 to the thickening tank 70 ) is concentrated in When the solid-liquid separation is achieved to some extent after a certain period of time has elapsed in the thickener 70, only the sedimentation material, which is generally solid, flows into the dehydrator 72 through the sludge valve for dewatering and is dehydrated, and then discharged in the form of a sludge dewatering cake. do. The desorbent generated in this process cannot be used again because of poor water quality and is generally re-introduced into the concentration tank 70 and re-concentrated. At this time, the coagulant from the coagulant injection unit 71 is injected into the concentration tank 70 to settle contaminants for solid-liquid separation.

Next, a cleaning process using the submerged membrane filtering unit 10 in which the ceramic separation membrane 20a is disposed in an immersion type will be described in detail. Backwash water, which is washing water to be used in the washing process, collects some of the treated water flowing into the treatment water tank 40 into the backwash water storage tank 50 . This cleaning process may be divided into scrubbing by the blower 30 , backwashing by backwashing water, and sprinkles.

Air from the blower 30 flows into the pipe 23 for air diffuser. As shown in FIG. 2 , the diffuser pipe 23 is connected to the diffuser branch pipe 23a at the lower portion of the ceramic membrane tower 20 , and the air introduced from the blower 30 is discharged from the ceramic membrane tower 20 at the lower end of the ceramic membrane tower 20 . Scrubbing is performed by brushing the ceramic separator 20a from the outside.

Backwashing by such backwashing water is performed in a direction opposite to that of the treated water discharge line. The backwash water collected in the backwash water storage tank 50 passes through the backwash valve by the backwash pump 52 and flows in the reverse direction to the treated water outlet 21 from which the treated water was discharged. At this time, the chemical may be additionally injected using the chemical injection pump 53 and the chemical injection valve. As such, the backwash water introduced in the reverse direction flows into the ceramic separator 20a, washes the inside of the ceramic separator 20a, and then is discharged to the outside, that is, to the inside of the submerged membrane filter 10 . In other words, the raw water flows into the ceramic separator 20a from the inside of the submerged membrane filtration unit 10 and becomes treated water and is discharged to the outside of the ceramic separator 20a in the opposite direction. Through this, foreign substances caught in pores connecting the inside and outside of the ceramic separator 20a can be discharged, and thus, the inside of the ceramic separator 20a can be cleaned.

Similarly, washing water for sprinkles is supplied from the backwashing water storage tank 50 . Washing water passes through the sprinkler valve by the sprinkler pump 51 and flows into the sprinkler pipe 22 . Similarly, the chemical may be additionally injected using the chemical injection pump 53 and the chemical injection valve. As shown in FIG. 1B , since the sprinkler pipe 22 is installed to spray the washing water downward from the top of the ceramic membrane tower 20, the washing water washes the outside of the ceramic membrane 20a.

As described above, in order to minimize the environmental impact and secure safety when discharging or reusing the treated water, a disinfectant material such as chlorine or ozone must be supplied to the treated water collected in the treatment water tank 40 . According to the prior art, chlorine supplied from the chlorine injection unit 60 is generally used, but at this time, a large amount of chlorine is used, and it is difficult to inject an appropriate level of chlorine ions depending on the quality of the treated water. have. Accordingly, it is possible to sterilize by injecting ozone instead of or together with chlorine, and in this case, a separate ozone generator and ozone injection facility are used.

Meanwhile, as a prior art, Korean Patent Registration No. 10-1771418 discloses an invention entitled "a separation membrane module for water treatment and a separation membrane module operating device using the same", which will be described with reference to FIG. 2 .

2 is a view showing a separation membrane module operating device according to the prior art, in which a) of FIG. 2 is a perspective view of the coupled state of the separation membrane module operating device, and FIG. 2 b) is a perspective view of a separation membrane cartridge.

2 a) and b), the separation membrane module operating device 80 according to the prior art includes a separation membrane cartridge 81, a cleaning device 82, and a water tank 83, and the separation membrane cartridge Reference numeral 81 includes a flat-film ceramic separator 81a, an upper plate 81b, a lower plate 81c, and a fixing means 81d.

The separation membrane cartridge 81, as shown in FIG. 2 b), includes a plurality of flat membrane ceramic separation membranes 81a arranged in parallel at regular intervals; an upper plate (81b) and a lower plate (81c) supporting the upper and lower ends of each of the plurality of flat-film ceramic separators; and fixing means (81d) for fixing the upper plate (81b) and the lower plate (81c). In this case, the lower plate 81c has a structure in which the first lower plate 81c-1 and the second lower plate 81c-2 are laminated.

The cleaning device 82 includes a plurality of cleaning plates inserted between the plurality of flat-film ceramic separators 81a; and a pair of frames supporting both side ends of the washing plate and having drain holes, wherein the washing plate is held between the upper plate 81b and the lower plate 81c.

The water tank 83 accommodates the separation membrane module, and in this case, the water tank 83 includes an inlet provided at the front end, a return flow port provided at the rear end, and a filtration drain port provided under the separation membrane module.

The separation membrane module operating device according to the prior art combines and applies a filtration method that combines a coulometric filtration method and an orthogonal filtration method, so that maintenance is easy and advantageous for continuous operation. There are advantages in terms of continuous operation and maintenance by introducing

However, in the case of a separation membrane module operating device according to the prior art, a flat membrane type ceramic membrane module is provided that combines and applies a filtration method that combines only a quantitative filtration method and an orthogonal filtration method.

On the other hand, the advanced oxidation process (AOP) is a chemical treatment method that removes organic solvents (or inorganic solvents) in water or wastewater through an oxidation reaction using hydroxyl radicals (OH) in a broad sense, and ozone (O ₃ ) and It refers to a chemical process using hydrogen peroxide (H ₂ O ₂ ) or UV light. The hydroxyl radical (OH) generated through this advanced oxidation process is the strongest oxidizing agent in existence, capable of oxidizing virtually any compound dissolved in water, and often acts as a diffusion-controlling reaction rate.

As a result, the moment hydroxyl radicals are generated, they react indiscriminately with contaminants, decomposing contaminants very quickly and efficiently into small inorganic molecules, Ozone, hydrogen peroxide, oxygen, etc.) or an energy source or catalyst (eg ultraviolet light, titanium dioxide, etc.).

As such, the advanced oxidation process using ozone is a powerful organic matter oxidation and disinfection process, and it is possible to remove not only difficult-to-decompose organic matter such as natural organic matter (NOM), high molecular compounds, and trace organic matter, but also taste odor substances and color. It is widely used in water treatment.

In addition, the aforementioned membrane filtration process is widely used not only in Korea but also worldwide because of advantages such as superior quality of treated water and use of a small site area. This occurs, and the decrease in the amount of treated water due to such membrane contamination is pointed out as the biggest problem.

In addition, the advanced oxidation process based on ozone can be easily applied in the field with only electricity and oxygen, and ozone injection amount can be controlled and automated. There are disadvantages.

Accordingly, although the advanced oxidation process using ozone and the process linking the ceramic membrane are being studied in various places, when demonstrating this, the structure of the process itself becomes complicated and maintenance is difficult. In addition, when ozone is also supplied using an existing diffuser, the time and area in contact with the raw water to be treated may not be sufficient, which may result in a reduction in treatment performance.

Recently, a study linking the ozone oxidation process and ceramic membrane filtration is being conducted, but the ozone treatment tank for ozone oxidation reaction and the immersion type treatment tank for the ceramic membrane filtration process are separately performed and the corresponding process is performed.

On the other hand, according to the prior art, in the case of using ozone generated by using an advanced oxidation device in the ceramic separation membrane process for backwashing, an experiment of backwashing with ozone was conducted after sewage treatment using a tubular metal membrane. It was confirmed that higher water permeability efficiency was observed when backwashing with ozone was performed than when proceeding with offensive, and also, a technology for a device that performs filtration and washing in both directions using a ceramic separator has been disclosed, but in particular, the membrane A technology using a gas that can effectively remove pollution has not yet been confirmed.
