Membrane module, the good cleaning performance that can be taken is discharged in the pollutant of film surface.
According to operating condition, air purge is divided into single air purge and double air purges, such as single air purge can be thus capable of sufficiently recovering when time membrane pressure, then into
Row list air purge, single air purge step sequence are as follows：Filter 23 0 minute；Air purge, backwash, 30 seconds；It just washes, 30 seconds.
It is positive to rinse, it uses intake pump as positive flush power, opens membrane module concentrated water spout valve, close membrane module and produce mouth of a river valve,
It is rinsed with low-pressure, big flow.
Gas flushing is gas impulsion power by air compressor machine, enters from membrane module bottom and from bottom to top rinse, flushing pressure controls
Within 1Bar, the air purge flow of every film is 3-5m3, opens membrane module concentrated water spout valve, closes membrane module and produces mouth of a river valve.
Flushing water is entered from the membrane module production mouth of a river, is gone out from concentrated water as backwash power with backwashing pump by backwash method
Mouth and water inlet outflow control lower operating pressure (general≤0.1Mpa), to prevent having received high internal pressure, lead to membrane module inner membrance
Silk explosion.
When backwash, flushing water cannot be recycled, direct emission or original materializing strategy system is gone to be further processed.

After obtain pretreated waste water A, pretreated waste water A obtains B after coagulation floatation and biological aerated filter (BAF) processing successively
Liquid, B liquid, which enters in clear water reserviors, to be stored；Then, 1/5th B liquid flows into progress ozone in O3 contacted oxidation tower and connects
It is discharged after touching oxidation reaction, remaining 4/5ths B liquid flows into quartz filter obtains C liquid after filtering；C liquid
Recycle-water D and concentrated water E are obtained after the filtering of ultrafiltration film module, cartridge filter and reverse osmosis unit successively, recycle-water enters RO
It produces pond then to discharge, concentrated water E flows into RO concentrated waters pond, and then concentrated water E obtains F liquid, F liquid streams after the processing of Fenton reactor
Enter and carry out precipitation process in sedimentation basin, G liquid is obtained after separation of solid and liquid, G liquid streams, which enter in blowoff basin, discharges.
Dyeing waste-water and poaching wastewater are by grid filtration pond, regulating reservoir, rotary grate filtering ponds, primary sedimentation tank, hydrolysis
It is discharged after acidification pool and secondary settling tank, mixing of removing contamination after secondary clarifier effluent, water 2000m3/ d, water outlet flow to coagulation floatation certainly,
Air-floating apparatus in coagulation floatation is soluble in water by large quantity of air under pressure condition, forms dissolved air water, is situated between as work
Matter generates a large amount of micro air bubbles by the release sudden pressure reduction quick release in coagulation floatation.Micro air bubble is anti-with coagulation
It answers the condensation product in waste water to be adhered to each other, flco proportion is made to bubble through the water column less than 1, to make pollutant be separated from the water out
It goes, achievees the purpose that water purification.The water outlet of coagulation floatation flow to biological aerated filter certainly, attached on the filler in biological aerated filter
The microbial degradation organic matter, to achieve the purpose that water purification.The water outlet of biological aerated filter is divided into two gangs of 400m3/ d and
1600m3/ d, wherein 400m3/ d enters O3 contacted oxidation tower and carries out O3 contacted oxidation reaction, further decolourizes and removes
A small amount of COD, then qualified discharge；1600m3/ d is handled by dual membrane system, reverse osmosis unit output reuse water 1000m3/ d and
600m3/ d concentrated waters (COD concentration 250mg/L), concentrated water enter Fenton reactor and carry out Fenton's reaction, and dilute sulfuric acid is first added and adjusts pH
3 or so, while ferrous sulfate and hydrogen peroxide being added, further removes pollutant, then water outlet is flowed into sedimentation basin and is precipitated, Gu
After liquid separation, liquid adjusts back pH with sodium hydroxide, then discharges water to outside blowoff basin and arranges.
Table 1 is expected treatment effect
