Abstract
A modified starch washing wastewater and scraper wastewater treatment system comprises at least two depositing tanks and a homogeneous tank. A drainage pipe is arranged at the lower portion of each depositing tank, a valve is arranged on the drainage pipe, an overflow pipe is arranged on the upper half of each depositing tank, the depositing tanks are connected sequentially through the overflow pipe, the first depositing tank is connected with the homogeneous tank through a homogeneous tank overflow pipe, the homogeneous tank is communicated with a washing wastewater and scraper wastewater tank through pipelines, a sewage pump is arranged in the washing wastewater and scraper wastewater tank, and the pipelines are connected with the sewage pump. The treatment system is applied to washing procedures of corn starch and similar procedures.
Description
Technical field
The utility model belongs to sewage and transforms the field, relates in particular to a kind of converted starch washes and scraper waste water modernization system that is applied in cornstarch manufacturing enterprise.
Background technology
In cornstarch manufacturing enterprise, can produce a large amount of washes and scraper waste water in the washing converted starch operation.Directly discharge and pollute the environment, to these wastewater treatment method be at present, with sewage pump with in washes and a plurality of settling tanks of scraper waste water suction, the precipitation a period of time after, with settling tank at the middle and upper levels primary water enter Sewage Plant then with sewage pump suction homogeneous jar.Because the slurry amount is big in this operation, the settling tank sedimentation time is not enough, can not continuous drainage.Addressed this problem two kinds of methods: a kind of method is to stop to wash the converted starch operation earlier, waits for that the washes in the settling tank precipitates the continuation production of good back.This method can not continuous drainage, can delay the production time.Another kind method is to buy a large amount of settling tanks, the all continuous suction settling tank of all washes, time order and function according to washes in the suction settling tank, clarify earlier of elder generation's suction can be discharged by first suction homogeneous jar, also can realize continuous blow-down according to time order and function in other the settling tank, but this method needs a large amount of settling tanks, a large amount of settling tanks need take workshop, and needs to be equipped with the staff, has increased equipment cost and cost of labor.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency a kind of converted starch washes and scraper Waste Water Treatment is provided, can continuous blow-down sewage, saved the production time in a large number.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of converted starch washes and scraper Waste Water Treatment, comprise settling tank and homogeneous jar, at least two of described settling tanks, be connected with blow-off pipe in the settling tank bottom, blow-off pipe is provided with valve, settling tank the upper half tank body is provided with overflow pipe, settling tank connects by overflow pipe successively, first settling tank is connected with the homogeneous jar by homogeneous jar overflow pipe, the homogeneous jar is by pipeline and washes and scraper wastewater trough UNICOM, be provided with sewage pump in washes and scraper wastewater trough, pipeline is connected with sewage pump.
Above-mentioned converted starch washes and scraper Waste Water Treatment, described settling tank are three, and three settling tanks are successively by overflow pipe UNICOM.
Above-mentioned converted starch washes and scraper Waste Water Treatment, described settling tank are two, and two settling tanks are by overflow pipe UNICOM.
Adopt technique scheme, the utility model has following advantage: washes and scraper waste water are pumped in the homogeneous jar through sewage pump, from the homogeneous jar, overflow to first settling tank, sewage in first settling tank overflows to second settling tank again behind certain altitude, the 3rd settling tank of flowing through successively, discharge from the blow-off pipe of the 3rd settling tank bottom, washes and arsenic cutter waste water are through homogeneous jar preliminary sedimentation like this, with the upper strata comparatively settled sewage overflow to first settling tank, further clarify at first settling tank, overflow to second settling tank again, clarify for the third time at second settling tank and overflow to the 3rd settling tank, discharge from the blow-off pipe of the 3rd settling tank bottom at last.Need not change can reach the blowdown requirement through precipitation a period of time, realize the purpose of continuous blowdown, corresponding washing converted starch operation just need not be waited for precipitation, can produce continuously.Saved a large amount of production times.The utility model is simple in structure, and use equipment is less, only adds several overflow pipes on the basis of original equipment, saves a sewage pump simultaneously, just can realize the quantity-produced effect.Be adapted at using in the washing procedure of cornstarch or like product.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is first kind of structural representation of the present utility model.
The specific embodiment
As depicted in figs. 1 and 2 a kind of converted starch washes and scraper Waste Water Treatment, comprise settling tank and homogeneous jar, at least two of settling tanks, be connected with blow-off pipe in the settling tank bottom, blow-off pipe is provided with valve, settling tank the upper half tank body is provided with overflow pipe, settling tank connects by overflow pipe 16 successively, first settling tank is connected with homogeneous jar 3 by homogeneous jar overflow pipe 17, homogeneous jar 3 is by pipeline 2 and washes and scraper wastewater trough 15 UNICOMs, in washes and scraper wastewater trough 15, be provided with sewage pump 1, pipeline 2 is connected with sewage pump 1, homogeneous jar 3 bottoms are provided with homogeneous jar blow-off pipe 5, and homogeneous jar blow-off pipe 5 is provided with homogeneous tank valve 4, conveniently regularly discharge sediment from the homogeneous jar.
As shown in Figure 1, settling tank is two 6,9, first settling tank 6 and second settling tank 9 are by overflow pipe UNICOM, the bottom of first settling tank 6 is provided with the first settling tank blow-off pipe 8, the first precipitation blow-off pipe 8 is provided with first valve 7, with opening first valve after a period of time the sediment in first settling tank is discharged, the bottom of second settling tank 9 is provided with the second settling tank blow-off pipe 11, second blow-off pipe 11 is provided with second blowoff valve 10, and the sewage that enters in second settling tank is discharged continuously by second blow-off pipe 11.
As shown in Figure 2, settling tank is three 6,9,12, first settling tank 6, second settling tank 9 and the 3rd settling tank 12 are successively by overflow pipe UNICOM, the first precipitation blow-off pipe 8 is provided with first valve 7, with opening first valve after a period of time the sediment in first settling tank is discharged, the bottom of second settling tank 9 is provided with the second settling tank blow-off pipe 11, second blow-off pipe 11 is provided with second blowoff valve 10, the effect of second blow-off pipe is identical with the effect of first blow-off pipe, all be used to discharge sedimentary, the bottom of the 3rd settling tank 12 is provided with the 3rd settling tank blow-off pipe 14, the 3rd blow-off pipe 14 is provided with the 3rd blowoff valve 13, washing uses waste water and scraper waste water through the homogeneous jar, first settling tank, second settling tank progressively precipitates clarification after the 3rd blow-off pipe 14 is discharged continuously three times, the effect of the blow-off pipe on other settling tanks and the homogeneous jar is in order regularly to remove the sediment in the tank body, better to produce continuously with convenient.
