Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Diagram is the structural representation of the treatment unit of a kind of comprehensive acidic and alkaline waste water of the present invention.
In figure: the total equalizing tank of 1-, 20-pH adjustment tank, 21-acidic solution volume pump, 22-high-voltage pulse coagulation bed, 3-one air-floating apparatus, 31-auxiliary material add in volume pump, 4-intermediate pool, 5-lime reaction pond, 51-and material volume pump, 6-settling tank, No. 1, the total equalizing tank of 7-, 8-PH always adjust pond, 81 sulfuric acid volume pumps, 9-acidication treating pond, 10-activated sludge tank, 11-biochemical sedimentation basin, 12-sludge thickener, 13-pressure filter.
Embodiment
The treatment unit of comprehensive acidic and alkaline waste water of the present invention, along processing direction, pipeline is connected with total equalizing tank 1, pH adjustment tank 20, high-voltage pulse coagulation bed 22, one air-floating apparatus 3, intermediate pool 4, lime reaction pond 5, settling tank 6 successively, always equalizing tank No. 17, PH always adjust pond 8, acidication treating pond 9, activated sludge tank 10, biochemical sedimentation basin 11, sludge thickener 12 and pressure filter 13.
Total equalizing tank 1 is for storing pending sewage, and sewage is carried out to homogeneous.
High-voltage pulse coagulation bed 22 is mainly removed the pollution factor in sewage, by applying high voltage effect, producing electrochemical reaction, is chemical energy electric energy conversion, can carry out redox reaction to the organism in sewage or inorganics, and then adsorb, condense, pollutent is separated from water body.
3 pairs of sewage of one air-floating apparatus carry out removing dross processing, by the external auxiliary material being connected with automatic control system of one air-floating apparatus, add volume pump 31, as flocculation agent and coagulating agent, grease in sewage etc. is separated, and deliver to sewage concentration tank, be convenient to focus on.
5 pairs, lime reaction pond sewage is removed suspended substance and the negatively charged ion in sewage, by lime reaction pond external be connected with automatic control system in and material volume pump 51, realize the accurate input of milk of lime, polyacrylamide.Can also remove salinity in sewage in addition, reduce the impact load of sewage to facility.
At lime reaction pond 5 and PH, always adjust 8, pond and be provided with settling tank 6, by precipitation, at the bottom of making part in sewage you what be deposited on pond, reduce treatment capacity and the intractability of later process, this settling tank is separately established pipeline communication road sludge thickener simultaneously, thereby focuses on the mud of separating in sewage.
At settling tank 6 and PH, always adjust 8, pond and be provided with total equalizing tank No. 17, utilize total equalizing tank No. 1 the water quality of sewage to be carried out to homogenizing, improve the dissolved oxygen in sewage and solve use all the year round after the problem of pool bottom sludge alluvial.
PH always adjusts 8 pairs, pond sewage and carries out neutralizing treatment, by PH, always adjusts the external sulfuric acid volume pump 81 being connected with automatic control system in pond, utilizes its injected volume of controlling sulfuric acid, guarantees that the pH value of sewage equals 5.By the pH value of sewage is adjusted to neutrality, for follow-up biochemical microbial growth breeding provides comparatively suitable water quality environment.
