Description
Technical field
The present invention relates to technical field of waste water processing more particularly to a kind of waste water treatment process.
Background technology
Waste water of the people discharged in number of storage tanks produced per day, this waste water is mainly by the excreta of life waste material and people institute
Pollution, quantity, ingredient and the concentration of pollutant are related with people's lives custom, water consumption.Sanitary sewage is general and does not contain
Noxious material, still, it has the condition suitable for microbial reproduction, containing a large amount of bacteriums and pathogen, from the point of view of sanitation point,
With certain harmfulness.Wastewater treatment is exactly to be handled waste water using the method for physics, chemistry and biology, keeps waste water net
Change, reduce pollution, so that reaching Sewage treatment, multiplexing, makes full use of water resource.
Invention content
To solve the above problems, the invention discloses a kind of waste water treatment process, the effect of processing waste water is effectively played.
In order to reach object above, the present invention provides the following technical solutions：
A kind of waste water treatment process, it is characterised in that：The specific steps are：
S1：Centrifuging treatment：Prepare centrifugal separator first, when frequency converter frequency be 25~30Hz when, by waste water be passed through from
The feed inlet of centrifugal separator, subsequent frequency converter frequency rise to 50~60Hz carry out high-speed separation, 6~8min of control time, later
The waste water being centrifuged out is passed into cyclone hydraulic separators again, and it is 15000~17000 to control Fr, 5~8min of time；
S2：Ceramic membrane filter processing：By treated in S1, waste water is passed into ceramic-film tube, and the flow velocity for controlling waste liquid is
1.1~1.5m3/ min, ceramic-film tube helically rise shape, and waste water enters from the lower port of ceramic-film tube；
S3：Anaerobic bio-treated：First container bottom install anaerobic reactor, anode and cathode be placed in container and submerge and
Among sludge, in addition, the bottom of container is also evenly equipped with ultrasonic transducer, then the bottom of the dirty water from container in S1 is led to
Enter, and the DC voltage of 0.5~0.8V is provided simultaneously, cathode directly generates hydrogen or methane gas is expelled directly out；
S4：Chemical precipitation is handled：Pure Fe is added into S3 treated waste water3O4Particle stirs 8~12min, is then added
NaOH solution adjusts pH value to 8.5~9.5, adds HCL solution later and adjusts pH value to 6.5~7.5, and it is stirred to react 15~
20min is separated by solid-liquid separation；
S5：Wastewater recycle processing：By sewage monitoring instrument to carrying out composition detection by S4 treated waste water, if Testing index
Waste water is then discharged in qualification, if detection is unqualified, the processing through S1, S2, S3 and S4 successively again, until each finger in waste water
Until mark is qualified.
Processing is centrifuged in the present invention first, prepares centrifugal separator, will when frequency converter frequency is 25~30Hz
Waste water is passed through the feed inlet of centrifugal separator, and subsequent frequency converter frequency rises to 50~60Hz and carries out high-speed separation, later will centrifugation

The mode that device is combined effectively removes the solid impurity in waste liquid, carries out basis for subsequent sewage disposal, is conducive to follow-up dirt
The efficiency of water process.
It is then handled using ceramic membrane filter, by treated in S1, waste water is passed into ceramic-film tube, and controls waste liquid
Flow velocity be 1.1~1.5m3/ min, ceramic-film tube helically rise shape, and waste water enters from the lower port of ceramic-film tube；Using pottery
Porcelain membrane tube, due to the densely covered micropore of ceramic membrane tube wall, under pressure, waste water flows in membrane tube or on the outside of film, small molecule object
Matter（Or liquid）Through film, macromolecular substances（Or solid particle, liquid drop）It is rejected by reach separation of solid and liquid, concentration
With the purpose of purifying, the little particle impurity in waste water can be effectively removed, in addition, by helically rising ceramic-film tube setting
Mode, not only increase the time of contact of waste water and ceramic-film tube, and by the effect by gravity, further increase pottery
The filter capacity of porcelain membrane tube all.
It uses chemical precipitation to handle later, pure Fe is added into S3 treated waste water3O4Particle stirs 8~12min, with
NaOH solution is added afterwards and adjusts pH value to 8.5~9.5, adds HCL solution later and adjusts pH value to 6.5~7.5, and stir anti-
15~20min is answered, is separated by solid-liquid separation；The mode that pH value is gradually adjusted by using two-stage, in removing sewage heavy metal from
While sub-, the control of pH value efficient fine is realized.
Wastewater recycle processing is finally carried out, by sewage monitoring instrument to carrying out composition detection by S4 treated waste water,
If Testing index is qualified, waste water is discharged, if detection is unqualified, the processing through S1, S2, S3 and S4 successively again, until useless
Until each qualified in water.
Further, the ultrasonic transducer in the S3 is connected with supersonic generator.
Further, pure Fe in the S43O4The grain size of particle is 13~15 μm.
Further, the NaOH content in the S4 in NaOH melts is 40~43%.
Further, the HCL contents in the S4 in HCL melts are 38~42%.
Compared with prior art, the beneficial effects of the present invention are：It is combined using centrifugal separator and cyclone hydraulic separators
Mode, effectively remove the solid impurity in waste liquid, carry out basis for subsequent sewage disposal, be conducive to follow-up sewage disposal
Efficiency；Using ceramic-film tube, due to the densely covered micropore of ceramic membrane tube wall, under pressure, waste water effluent in membrane tube or outside film
It is dynamic, small-molecule substance（Or liquid）Through film, macromolecular substances（Or solid particle, liquid drop）It is rejected by reach solid
The purpose of liquid separation, concentration and purifying, can effectively remove the little particle impurity in waste water, in addition, by setting ceramic-film tube
The mode helically risen is set, not only increases the time of contact of waste water and ceramic-film tube, and by the effect by gravity,
Further increase the filter capacity of ceramic-film tube all；The mode that pH value is gradually adjusted by using two-stage, the weight in removing sewage
While metal ion, the control of pH value efficient fine is realized.
