Description

A high-throughput sewage treatment device

Technical Field

The utility model relates to the technical field of sewage treatment, in particular to a high-throughput sewage treatment device.

Background Art

At present, the terminal of the urban sewage treatment system is basically the sewage treatment plant. Due to the large amount of urban sewage, the concentrated discharge volume after treatment by the sewage treatment plant is large, which has become a "point source" pollution source of urban water bodies to some extent. In response to this problem, the commonly used ecological technical measures are tailwater artificial wetlands, which purify sewage through the combined effects of vegetation and fillers. Existing tailwater artificial wetlands include horizontal flow artificial wetlands, horizontal subsurface flow artificial wetlands, vertical subsurface flow artificial wetlands, and ditch-type artificial wetlands.

However, tailwater artificial wetlands are very effective in filtering suspended solid particles and decomposing organic pollutants (BOD and COD), resulting in poor removal of nitrogen and phosphorus at a limited scale. Therefore, although the concentration of nitrogen and phosphorus in a single cubic meter of sewage is relatively low, when a large amount of sewage is discharged into tailwater artificial wetlands in a centralized manner, due to the low nitrogen and phosphorus treatment rate, the total amount of nitrogen and phosphorus pollutants contained in the large volume of sewage discharged after purification by tailwater artificial wetlands is high, posing an environmental threat to natural water bodies.

Example 1

In conjunction with Figures 1-3, this embodiment provides a high-throughput sewage treatment device, including:

A container 10, to which a water inlet pipe 13 and a water outlet pipe 30 are connected;

A packing assembly, the packing assembly includes a dephosphorization packing 17 and a supporting packing 18 which are sequentially arranged in the containing body 10 along the gravity direction;

The aeration assembly is connected to the top of the phosphorus removal filler 17 and the bottom of the supporting filler 18;

The tray 14 is connected to the containing body 10 , and the tray 14 and the water inlet pipe 13 are correspondingly arranged.

Specifically, during sewage treatment, first, sewage from the tailwater artificial wetland 50 enters the container 10 through the water inlet pipe 13. The material of the container 10 can be PVC or various metals; then, under the action of the tray 14, the sewage forms a leaping water flow toward the surroundings, which is convenient for the sewage to contact with the air, thereby facilitating the increase of the oxygen content of the sewage, and then facilitating the increase of microbial activity to promote the decomposition of pollutants in the sewage; the phosphorus removal filler 17 is used to remove phosphorus from the sewage, and the phosphorus removal filler 17 is preferably a mixture of blast furnace slag and alumina, and the mass ratio of blast furnace slag to alumina is 8:2. The phosphorus removal filler 17 is also convenient for providing a habitat for microorganisms; the supporting filler 18 is used to support the phosphorus removal filler 17, and the supporting filler 18 is preferably gravel, and the specific materials of the supporting filler 18 and the phosphorus removal filler 17 are different, which is convenient for avoiding various materials from being squeezed together and maintaining high-throughput characteristics. The supporting filler 1 8 is also convenient for providing a habitat for microorganisms; the aeration component is used to provide oxygen. Since the aeration component is connected to the top of the phosphorus removal filler 17 and the bottom of the supporting filler 18, it is convenient to divide the filler component into a first oxygen-rich zone 26, an anaerobic zone 27 and a second oxygen-rich zone 28 in the direction of gravity. The sewage undergoes nitrification in the first oxygen-rich zone 26 to convert nitrogen into ammonia, which is convenient for removing a part of the nitrogen in the sewage. The sewage undergoes denitrification in the anaerobic zone 27 to release nitrogen (pollution-free). The sewage undergoes nitrification again in the second oxygen-rich zone 28 to convert nitrogen into ammonia, which is convenient for removing another part of the nitrogen in the sewage. It should be noted that the second oxygen-rich zone 28 not only includes the area where the supporting filler 18 is located, but also includes the area where part of the phosphorus removal filler 17 is located; the outlet pipe 30 is used to allow the treated sewage to flow back to the tailwater artificial wetland 50, so as to stabilize the operating water level of the tailwater artificial wetland 50.

Specifically, the inverted cone shape makes it easier for sewage to gather toward the top center of the dephosphorization filler 17. Under the action of the geotextile 21, the tiny particles in the sewage accumulate at the geotextile 21 to form a silt layer 22, and the sewage enters the dephosphorization filler 17 through the geotextile 21, thereby preventing the tiny particles in the sewage from clogging the dephosphorization filler 17 and facilitating the cleaning of the tiny particles in the sewage.

Further, as shown in FIG. 1 , the size of the geotextile 21 is one third of the size of the container 10 .

Specifically, the container 11 and the top cover 12 are detachably connected, so as to facilitate timely maintenance of the tray 14, the filling assembly, etc. in the container 10.

Furthermore, as shown in FIG. 1 , a support 16 is further included, one end of the support 16 is connected to the tray 14 , and the other end of the support 16 is connected to the bottom of the container 11 .

Specifically, the support column 16 is used to connect the tray 14 in the container 11 to ensure the stability of the tray 14. The support column 16 can be made of stainless steel.

Specifically, the aeration unit is used to provide oxygen to a plurality of first aeration tubes 23 and a plurality of second aeration tubes 25; a plurality of first aeration tubes 23 are used to provide oxygen to the top of the dephosphorization filler 17; a plurality of second aeration tubes 25 are used to provide oxygen to the bottom of the supporting filler 18; two-thirds of a plurality of first aeration tubes 23 are inserted into the top of the dephosphorization filler 17, and a plurality of second aeration tubes 25 are fully inserted into the bottom of the supporting filler 18.

Furthermore, as shown in FIG. 2 , a plurality of first aeration tubes 23 are evenly distributed along the circumference of the container 10 ; and a plurality of second aeration tubes 25 are evenly distributed along the circumference of the container 10 .

Specifically, it is convenient to increase the uniformity of oxygen supply to the plurality of first aeration tubes 23 and the plurality of second aeration tubes 25 .

Further, as shown in FIG1 , it also includes:

A drain pipe 34 connected to the bottom of the container 10;

The valve body 35 is communicated with the exhaust pipe 34 .

Furthermore, as shown in FIG. 1 , a discharge pipe 33 connected to the container 10 is also included.

Specifically, when the operating water level of the tailwater artificial wetland 50 is stable and there is no need to circulate water through the outlet pipe 30, the treated sewage gradually accumulates in the container 10. When the water level exceeds the discharge pipe 33, the treated sewage overflows through the discharge pipe 33 into the natural soil or water body.

Furthermore, as shown in FIG2 , the cross-sectional shape of the container 10 is circular, elliptical or rectangular.

The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
