Description
Technical field
The utility model relates to a kind of suspension method production PVC paste resin process wastewater treatment equipment, belongs to wastewater treatment equipment technical field.
Background technology
Produce in the production process of microsuspending method production PVC paste resin and a large amount of wash still liquid, wherein about containing 1% PVC powder and be coated with still agent on a small quantity, produce additive etc.This washes still liquid after residual PVC is caught in dosing flocculation, and produce a large amount of containing organic waste water, COD, between 300 ~ 500mg/L, needs externally discharged waste water treatment plant to process, causes water waste simultaneously.
Summary of the invention
According to above deficiency of the prior art, technical problem to be solved in the utility model is: provide the suspension method production PVC paste resin process wastewater treatment equipment that a kind of structure is simple, save water source.
The utility model solves the technical scheme that its technical problem adopts:
Described suspension method production PVC paste resin process wastewater treatment equipment, comprise wastewater holding chamber, wastewater holding chamber, flocculation basin, the first sand-bed filter, biochemical aeration tank, second pond, clean water basin, the second sand-bed filter, reuse water pot are connected successively; Wherein, the pipeline between wastewater holding chamber, flocculation basin connects respectively PAC/PAM doser and NaOH doser; Pipeline between first sand-bed filter, biochemical aeration tank connects sanitary sewage storage pool; Pipeline between clean water basin, the second sand-bed filter connects PAC doser.
Also be connected with biochemical aeration tank top bottom described second pond.
Principle of work of the present utility model and process as follows:
(1) still liquid is washed from production plant, enter wastewater holding chamber, add PAC, PAM washing before still liquid enters flocculation basin, and regulate its pH value about 8.0 with NaOH, make the supernatant liquor after flocculation meet the requirement of biological treatment, the Main Function of flocculation basin is trapping PVC;
(2) supernatant liquor after flocculation directly enters activated sludge biochemical aeration tank after the first sand filters together with the sanitary sewage from sanitary sewage storage pool.Introducing the object of sanitary sewage is to meet in biochemical treatment microorganism to the needs of ammonia nitrogen.Control microorganism total amount, aeration intensity, the cycle of operation etc. in biochemical aeration tank, the COD value of biochemical aeration tank water outlet is reduced to 20 ~ 30mg/L; Increase the aeration rate of activated sludge biochemical aeration tank, clear up amount of activated mud, reduce the generation total amount of biological sludge.
(3) biochemical aeration tank water outlet is after second pond, clean water basin sedimentation, after mixing with the PAC flocculation agent from PAC doser, remove after suspended substance through the second sand filters again, reach recirculated water reuse standard, in order to replenishment cycles water, water for fire-fighting purpose, water flowers and irrigate the fields with water etc.
The beneficial effect that the utility model has is:
The means Treatment of Washing still waste water that the utility model adopts materializing strategy to be combined with biochemical treatment, thus reach the object of waste water recycling.After washing still waste water flocculation premenstruum trapping PVC, obtain being rich in organic waste water, to meet in biochemical treatment microorganism to after the needs of ammonia nitrogen through introducing sanitary sewage, then to degrade its organism be rich in thus the reuse water obtained for circulating cooling make-up water etc. through microbiological treatment, save water source.The reuse water that the utility model obtains, reaches the national recirculated water reuse standard that COD is less than 60mg/L.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In figure: 1, wastewater holding chamber; 2, PAC/PAM doser; 3, NaOH doser; 4, flocculation basin; 5, the first sand-bed filter; 6, sanitary sewage storage pool; 7, biochemical aeration tank; 8, second pond; 9, clean water basin; 10, PAC doser; 11, the second sand-bed filter; 12, reuse water pot.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figure 1, described suspension method production PVC paste resin process wastewater treatment equipment comprises wastewater holding chamber 1, and wastewater holding chamber 1, flocculation basin 4, first sand-bed filter 5, biochemical aeration tank 7, second pond 8, clean water basin 9, second sand-bed filter 11, reuse water pot 12 are connected successively; Wherein, the pipeline between wastewater holding chamber 1, flocculation basin 4 connects respectively PAC/PAM doser 2 and NaOH doser 3; Pipeline between first sand-bed filter 5, biochemical aeration tank 7 connects sanitary sewage storage pool 6; Pipeline between clean water basin 9, second sand-bed filter 11 connects PAC doser 10.Also be connected with biochemical aeration tank 7 top bottom second pond 8.
Wash still liquid from production plant, enter wastewater holding chamber 1, add PAC, PAM washing before still liquid enters flocculation basin 4, and regulate its pH value about 8.0 with NaOH, make the supernatant liquor after flocculation meet the requirement of biological treatment.
Supernatant liquor after flocculation directly enters activated sludge biochemical aeration tank 7 after the first sand-bed filter 5 filters together with the sanitary sewage from sanitary sewage storage pool 6.Introducing the object of sanitary sewage is to meet in biochemical treatment microorganism to the needs of ammonia nitrogen.Control microorganism total amount, aeration intensity, the cycle of operation etc. in biochemical aeration tank 7, the COD value of biochemical aeration tank 7 water outlet is reduced to 20 ~ 30mg/L; Increase the aeration rate of biochemical aeration tank 7, clear up amount of activated mud, reduce the generation total amount of mud.
Biochemical aeration tank 7 water outlet is after second pond 8, clean water basin 9 sedimentation, after mixing with the PAC flocculation agent from PAC doser 10, again after the second sand-bed filter 11 filter and remove suspended substances, reach recirculated water reuse standard, in order to replenishment cycles water, water for fire-fighting purpose, water flowers and irrigate the fields with water etc.
