In order to improve the resistance to dry combustion method performance of electric heat-generating disc, electric heat-generating disc need to be carried out pickling oxidation processes.At pickling oxidation Can produce during reason and substantial amounts of acid clean waste water, these direct discharging of waste water will polluted-water, welding.For This, a kind of acid Waste Water Treatment that cleans of necessary design carries out purified treatment to waste water, thus protects environment.
Utility model content
The purpose of this utility model is to provide that a kind of high treating effect, operation management be simple, stable and reliable operation, occupation of land face Long-pending acidity little, that cost is low cleans Waste Water Treatment.
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is: a kind of acid waste water that cleans processes System, including regulating reservoir, PH coarse adjustment pond, one-level coagulative precipitation tank, two-stage coagulation sedimentation tank, middle water pot, BAF pond, sand filter With reuse water pot, produce waste water and flow into described regulating reservoir, by water pump, the waste water in described regulating reservoir is extracted into described PH coarse adjustment Pond, is extracted into the waste water in described PH coarse adjustment pond in described one-level coagulative precipitation tank by water pump, described one-level coagulative precipitation tank In reacted waste water flow into described two-stage coagulation sedimentation tank, in described two-stage coagulation sedimentation tank, reacted waste water flows into described Middle water pot, is extracted into the waste water in described middle water pot in described BAF pond by water pump, and the waste water in described BAF pond flows into Described sand filter, waste water is after described sand filters, and the clean water flowed out from described sand filter flows into described reuse water pot.
Further, the mud discharging in described one-level coagulative precipitation tank and two-stage coagulation sedimentation tank in mud scratch pool, The mud input sludge concentration tank of described mud scratch pool, the supernatant in described sludge concentration tank inputs described regulating reservoir, institute State the mud in sludge concentration tank concentrated after input pressure filter, the filtrate that described pressure filter extrudes inputs described regulating reservoir, institute State the mud cake outward transport process that pressure filter extrudes.
Further, periodically Caustic soda is put in described PH coarse adjustment pond and carry out coarse adjustment.
Further, periodically Caustic soda is put into described one-level coagulative precipitation tank.
Further, described one-level coagulative precipitation tank and two-stage coagulation sedimentation tank are equipped with blender.
This utility model beneficial effect: the acid Waste Water Treatment that cleans of the present utility model carries out just step to waste water Joint, neutralized crude regulation, one-level coagulating sedimentation, two-stage coagulation precipitation, biochemical reaction process and filter sand process, and waste water is cleaned into clean Water purification, purified treatment is effective, and this acidity is cleaned that the operation management of Waste Water Treatment is simple, stable and reliable operation, account for Ground area is little, cost is the lowest.

Detailed description of the invention
Below in conjunction with accompanying drawing of the present utility model, the technical scheme in this utility model embodiment is carried out clear, complete Describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments wholely. Based on the embodiment in this utility model, those of ordinary skill in the art are obtained under not making creative work premise Every other embodiment, broadly falls into the scope of this utility model protection.
As it is shown in figure 1, a kind of acid of the present embodiment cleans Waste Water Treatment.This acidity cleans Waste Water Treatment bag Include regulating reservoir 11, PH coarse adjustment pond 12, one-level coagulative precipitation tank 13, two-stage coagulation sedimentation tank 14, middle water pot 15, BAF pond 16, sand Filter 17 and reuse water pot 18.Waste water tentatively regulates in flowing into regulating reservoir 11, after preliminary regulation, and will regulation by water pump 19 Waste water in pond 11 is extracted in PH coarse adjustment pond 12, owing to periodically can be put into by Caustic soda in PH coarse adjustment pond 12, in PH coarse adjustment pond 12 Caustic soda and waste water carry out reaction and carry out coarse adjustment, improve the pH value of waste water.After coarse adjustment, by water pump 19 by PH coarse adjustment pond 12 Interior waste water is extracted into one-level coagulative precipitation tank 13, owing to periodically Caustic soda can be put in one-level coagulative precipitation tank 13, and one-level coagulation Caustic soda in sedimentation tank 13 and waste water carry out one-level coagulating precipitation, in order to react fully, in one-level coagulative precipitation tank 13 Being provided with blender, the waste water in one-level coagulative precipitation tank 13 is stirred by this blender.After first order reaction precipitates, one-level is mixed Waste water in solidifying sedimentation tank 13 carries out two-stage coagulation reaction precipitation in flowing into two-stage coagulation sedimentation tank 14, in order to react fully, Being provided with blender in two-stage coagulation sedimentation tank 14, the waste water in two-stage coagulation sedimentation tank 14 is stirred by this blender.Through one The float in waste water and other impurity is eliminated after level, two-stage coagulation reaction precipitation.Waste water in two-stage coagulation sedimentation tank 14 Deposit in water pot 15 in the middle of flowing into, by water pump 19, the waste water in middle water pot 15 is extracted into BAF pond 16, giving up in BAF pond 16 Water carries out the biochemical reaction under aeration and processes, and the microorganism in waste water is resolved under the effect of activated sludge and removes, afterwards Waste water in BAF pond 16 flows into sand filter 17, and sand filter 17 carries out filter sand process to waste water, removes the chiltern of residual in waste water, The clean water inflow reuse water pot 18 flowed out from sand filter 17 stores, and the clean water in reuse water pot 18 is transported to Pickling-shop and returns With process.
Wherein, the mud being settled out in one-level coagulative precipitation tank 13 and two-stage coagulation sedimentation tank 14 deposits in mud scratch pool 131, the mud input sludge concentration tank 132 of mud scratch pool 131 carries out concentration, the supernatant in sludge concentration tank 132 Input regulating reservoir 11 processes again, the concentrated rear input pressure filter 133 of mud in sludge concentration tank 132, pressure filter 133 The filtrate input regulating reservoir 11 extruded processes again, the mud cake outward transport landfill disposal that pressure filter 133 extrudes.
Of the present utility model acid clean Waste Water Treatment successively waste water is tentatively regulated, neutralized crude regulation, one After level coagulating sedimentation, two-stage coagulation precipitation, biochemical reaction process, filter sand process, waste water is cleaned, high treating effect, and should The operation management of system is simple, stable and reliable operation, floor space is little, cost is the lowest.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this Within the spirit of utility model and principle, any modification, equivalent substitution and improvement etc. made, should be included in this utility model Protection domain within.
