Description

The fluoride waste treatment system
Technical field
The utility model relates to a kind of Waste Water Treatment, is specifically related to a kind of fluoride waste treatment system.
Background technology
For fluoride waste, generally adopt calcium salt precipitation method, promptly in waste water, add lime, make fluorion and calcium ion generate CaF 2The precipitation and remove.This technology have method simple, handle advantages such as convenient, that expense is low, handle the back water outlet and be difficult to up to standard, body refuse sedimentation slowly and shortcoming such as dehydration difficulty but exist.
Because fluorochemical is not unique pollutent that will be removed in the waste water, therefore to select suitable treatment process simultaneously according to practical situation.When for example being dissolved with yellow soda ash, Sodium Hydrogen Carbonate in the fluoride waste, directly add lime or calcium chloride, defluorination effect can reduce.
Handle fluoride waste at present following several method is arranged: chemical precipitation method can be handled the fluoride waste of high density, when the fluorion starting point concentration is 1000~3000mg/L, ultimate density after lime method is handled can reach 20~30mg/L, and this method is easy and simple to handle, and processing costs is low.But because the body refuse settling velocity is slow, need to add calcium chloride or other flocculation agent, precipitation is quickened.Flocculent precipitation is poor to the various amounts of fluoride in drinking water defluorination effect, and sulfate concentration is higher in the water of processing back.Absorption method only is applicable to the drinking water deep processing that the water yield is less, and sorbent material greatly more plays the anionresin effect, so defluorination effect is fairly obvious, but all will add the particular processing agent and particular device is set, and processing costs often is higher than the precipitator method, and complicated operation.
The utility model content
According to above the deficiencies in the prior art, technical problem to be solved in the utility model is: a kind of fluoride waste treatment system is provided, can effectively purifies fluoride waste, and the processing efficiency height.
Fluoride waste treatment system described in the utility model is connected with wastewater equalization pond, PH adjustment pond, PH stabilization pond, chemical reaction pond, flocculation basin, rectangular sedimentation tank, high-efficiency pipe chute settling tank, deoxygenation strainer and discharging pond successively by pipeline.
Wherein, PH adjusts the bottom of pond, PH stabilization pond, chemical reaction pond, flocculation basin, rectangular sedimentation tank and high-efficiency pipe chute settling tank can pass through the pipe connection sludge sump, the precipitation of its inside is delivered in the sludge sump utilizes.
The pond can be adjusted by pipe connection waste water in sludge sump top, is transmitted back to the waste water in the sludge sump in the wastewater equalization pond again; The pipe connection plate and frame(type)filter press can be passed through in the sludge sump bottom, and the mud in the sludge sump carries out processed through plate and frame(type)filter press.
Treatment process of the present utility model is as follows: by the residue sewage of atmosphere condensation station discharging, entering wastewater equalization pond carries out homogeneous and all measures, adjust the pond through being pumped to PH, utilize the PH adjustment pond that acts on of agitator fully to contact with milk of lime, make the pH value of water quality be fine-tuning to 8, flow in the PH stabilization pond, increase the concentration of calcium ion in the water quality earlier, add the calcium chloride for preparing earlier, add the polymeric aluminum chlorides solution for preparing again, under stirring action, entering chemical reaction pond after the mixing fully reacts, flocculation basin is gone in overflow again, adds PAM at this, and sewage is fully flocculated, and flow in the rectangular sedimentation tank certainly and precipitate, the supernatant liquor overflow is to subsequent processing---the high-efficiency pipe chute settling tank, precipitate once more, and fluorion in the water and most suspended substances are fully removed, the water outlet of high-efficiency pipe chute settling tank is from flowing into Buffer Pool, be promoted to the defluorination filter process through pump again, handle the back water outlet and satisfy qualified discharge requirement or recycle requirement fully, a part is back to preparing lime milk.Mud in the sludge sump is through the plate and frame(type)filter press processed, and mud mixes the raw material of conduct production cement in the fluorgypsum after airing, and the sewage in the sludge sump is got back to wastewater equalization pond.
The beneficial effect that the utility model had is: handle high dense fluoride waste more stable reliable, operating maintenance is very convenient, cycle of operation flexibility and changeability, anti impulsion load performance are strong, can stablize simultaneously the every principal reaction index of control waste water, guaranteed the processing efficiency height, effluent quality is good.Select for use rectangular sedimentation tank and high-efficiency pipe chute settling tank to carry out the secondary solid-liquid separation, thereby improved the effect of solid-liquid separation, improve the clarity of water outlet.Whole system is carried out and is safeguarded control automatically, saves personal expenditures, effectively reduces running cost.
