Accompanying drawing explanation
Fig. 1 is coating wastewater treatment unit schematic diagram described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.
As shown in Figure 1, a kind of coating wastewater treatment unit, comprises wastewater collection pond (not shown), filtration unit, and described filtration unit comprises coarse filtration strainer (not shown) and ultra filtration filter 10; The feed-water end of described ultra filtration filter 10 is provided with water-in, water side is provided with and produces the mouth of a river and concentrated water discharge mouth, and is respectively equipped with water intaking valve 11, product water valve 12 and concentrated water discharge valve 14.
Wherein, described coarse filtration strainer adopts cloth envelop collector, is retained by contaminant particle larger in waste water in cloth bag, to alleviate the burden of ultra filtration filter, improves filter effect and the work-ing life of ultra filtration filter.
Wherein, the pipeline of feed-water end of described ultra filtration filter 10 and the pipeline of water side are all provided with tensimeter P1 and under meter FI, in order to monitor the pressure of pipeline.Also separate the pipeline of a pipeline to matting case at the feed-water end of described product water valve 12, and the break-make of CIP (situ cleaning) liquid-outlet valve 15 pilot piping is installed.Feed-water end for concentrated water discharge valve 14 is also provided with a pipeline for passing into clear water, go out to strengthen concentrated water drainage, this pipeline adopts CIP liquid-outlet valve 16 to control, and connects from the water side of CIP liquid-outlet valve 15, diluting dense water of the waste water that direct utilization is handled well, is beneficial to the discharge of dense water.Enter low spot after this concentrated water drainage goes out and be disposed to dense water collecting device.
In order to improve the effect of wastewater treatment, be also connected with matting water intaking valve 13 at the feed-water end of ultra filtration filter 10, for carrying out the interpolation of chemical reagent to waste water, to promote the purifying treatment of waste water.
Wherein, the concentrated water discharge mouth place of described ultra filtration filter 10 is also connected with cross-flow pipeline, and described cross-flow pipeline is provided with cross-flow valve 17.Described cross-flow valve 17 is normally open valve.Described cross-flow pipeline is used for carrying out cross flow filter, so-called cross flow filter refers under the promotion of pump, waste water to be filtered is parallel to ultra-filtration membrane flowing, hydraulic pressure is then perpendicular to ultra-filtration membrane, by waste water filtering to ultra-filtration membrane another side, the much filtrate being trapped in ultrafiltration membrane surface is then discharged with the dense water formed after waste water filtering.
Wherein, the ultrafiltration membrane elements of described ultra filtration filter 10 inside adopts the Fil0860 series ultrafiltration membrane element of Xiamen Fei Tang membrane technique company limited.
During described coating wastewater treatment unit work, waste water enters ultra filtration filter 10 through water intaking valve 11, after ultra filtration filter 10 leaches, is divided into dense water and clear water two-way.Wherein, clear water is clean water, discharges from the product mouth of a river, and dense water is the high-concentration waste water after concentrating, and is expelled to stationary installation from concentrated water discharge mouth.
Wherein, described ultra filtration filter 10 is also connected with backwash pipeline, and described backwash pipeline comprises backwash suction culvert, backwash discharge pipe and admission passage, and is respectively equipped with backwash water intaking valve 21, backwash bleed valve 22 and intake valve 23.Backwash suction culvert connects the product mouth of a river of ultra filtration filter 10 water side, and controls break-make by backwash water intaking valve 21; Described backwash discharge pipe then connects the water-in of ultra filtration filter 10, and controls break-make by backwash bleed valve 22; Meanwhile, be also connected with admission passage at the water-in of ultra filtration filter 10, described admission passage is provided with intake valve 23, is controlled the break-make of admission passage by intake valve 23.Described admission passage adopts air compressor compress inlet air.
After ultra filtration filter uses for some time, the much filtrate of the ultrafiltration membrane surface meeting depositing dosed quantities of ultra filtration filter inside, now, needs to carry out backwash to ultra filtration filter, to remove these much filtrate.When backwash, water intaking valve, product water valve and concentrated water discharge valve, cross-flow valve are all closed, and pure water enters from backwash water intaking valve, reverse by ultra filtration filter, are then expelled to dense water collecting device from backwash bleed valve; Meanwhile, open intake valve, with the water entering surface of the inner ultra-filtration membrane of gas bleed ultra filtration filter, the much filtrate be deposited on herein is broken up, cleans to coordinate the pure water of backwash.Described intake valve can control the pressure of air inlet, to reach best backwash effect.
Coating wastewater treatment unit described in the utility model, by arranging coarse filtration strainer and ultra filtration filter, carries out two-stage filtration to coating wastewater; Meanwhile, backwash pipeline is arranged to ultra filtration filter, utilize backwash pipeline regularly to clean ultra filtration filter, realize situ cleaning, improve waste water treatment efficiency.Coating wastewater treatment unit described in the utility model, structure is succinct, easy to use, and waste water treatment efficiency is high.Coating wastewater treatment unit described in the utility model, can reach following effect:
Although the utility model with preferred embodiment openly as above; but it is not for limiting the utility model; any those skilled in the art are not departing from spirit and scope of the present utility model; can make possible variation and amendment, the scope that therefore protection domain of the present utility model should define with the utility model claim is as the criterion.
