Description
Technical field
This utility model relates to sewage-treatment plant, a kind of efficient air-floating segregation apparatus needing to carry out the sewage of dissolved air flotation process.
Background technology
In the treatment of waste water, often using air supporting method, air supporting is to make float bubbles attached rise to the water surface; thus separate the method for treating water of water and float; also make surfactant in water be attached to bubble surface to float, thus be separated from water, referred to as foam air supporting method.Air supporting method can be used for the inapplicable occasion of the sedimentation method, is bordering on water with segregation ratio reclosing and is difficult to the float precipitated, such as oils and fats, fiber, algae etc., it is also possible to concentrate activated sludge.Air supporting rely primarily on float surface have hydrophilic and hydrophobic point, the easy bubbles attached of hydrophobicity particle surface, thus available air supporting method, hydrophilic particle can transfer hydrophobicity to after processing with suitable chemical drugs.Before carrying out air supporting method, conventional coagulant makes colloidal solid form for flco, flco has network structure, easily voids, thus improve daf efficiency, furthermore, water can form foam if any surfactant (such as detergent), also have the effect that attachment particle rises together.Using air-float method to remove suspension refuse faster than precipitation, and clearance is good, can reduce biochemical sludge below to a certain extent, therefore air supporting is widely applied.
The equipment that air supporting method uses is generally referred to as air-flotation separation equipment, it is a kind of solid suspension, oils and fats and sewage treatment equipment of various jelly removed in various industry and municipal wastewater, before being generally used for biochemical treatment, it has included the flotation tank of separation process and has produced the auxiliary device of bubble.But current flotation tank structure is single, the pattern removing waste water contamination is single, and when running into heavier dirt, it is impossible to make it suspend so that water treatment effect is deteriorated.
Utility model content
The technical problems to be solved in the utility model is to overcome existing air-flotation separation equipment structure single, removes the defect that the pattern of waste water contamination is single, it is provided that a kind of efficient air-floating segregation apparatus.
In order to solve above-mentioned technical problem, this utility model provides following technical scheme:
A kind of efficient air-floating segregation apparatus, including the chemical reaction pond being sequentially communicated, FLOTATION SEPARATION pond and clear water reserviors；
Described chemical reaction pond is divided into third-order reaction pond by two dividing plates；Dividing plate includes deflection plate and deflector；The top of described deflection plate is fixed on the top of described chemical reaction pond, bottom not with the bottom connection of described chemical reaction pond；Described deflector is fixed on the bottom of described chemical reaction pond, and not top with described chemical reaction pond, upper end connects.Feature for different waste water can set different dosing kind, quantity and the reaction conditions such as PH, ORP value, so that pollutant reach best chemical reaction and coagulation, flocculating effect in reaction tanks at different levels；Original float knot dosing coagulation and flocculation in the subparticle and the waste water that produce after chemical reaction, then by arranging different response speed, gradient, generate the agglutinating matter of larger particles, to reach optimal coagulation and flocculating effect；
Described FLOTATION SEPARATION pond is made up of contact chamber, flash trapping stage pond, aerosol filtering area and the second-order separation pond successively, and described contact chamber, flash trapping stage pond, aerosol filtering area connect with the top in the second-order separation pond, and bottom cuts off.The waste water that coagulation is good initially enters contact chamber and flash trapping stage pond, waste water carries out being fully contacted mixing with dissolved air water in contact chamber, the micro air bubble of dissolved air water release is gathered in around flocculate formation copolymer, proportion obtains FLOTATION SEPARATION less than the copolymer of water in flash trapping stage pond, and proportion sinks to assembling more than the copolymer of water and periodically got rid of to the sludge bucket of bottom, flash trapping stage pond；Then proportion enters aerosol filtering area and the second-order separation pond close to the copolymer of water with current, the a large amount of micro air bubbles being full of dissolved air water release in aerosol filtering area and produce, when remaining flocculate in waste water passes through filtering area with current, the flocculate surface of remaining is surrounded by micro air bubble rapidly, the copolymer generated is lighter than the copolymer proportion that contact chamber produces, and then obtains fast-flotation in the second-order separation pond and separates；After the second-order separation, water outlet enters clear water reserviors through collector pipe uniform collection, and the scum silica frost on top, FLOTATION SEPARATION pond scrapes to sludge sump discharge by chain-type Slag Scraping Device.FLOTATION SEPARATION pond carries out secondary flotation separation to the flocculate in waste water, the most thoroughly removes all kinds of flocculation polluters in waste water；
Clear water reserviors are storage air supporting final outflow water and can use as molten gas recirculation water.Water level control apparatus is set in clear water reserviors, in order to regulate FLOTATION SEPARATION pool water level.
Further, FLOTATION SEPARATION pond is provided with blowdown apparatus
Further, described bottom, flash trapping stage pond is provided with precipitation bucket and automatic sewage discharging device, can be according to water quality situation auto-controll operation, it is not necessary to manual intervention.
Further, the reaction tanks at different levels of described chemical reaction pond are provided with control instrument and chemicals dosing plant.
Of the present utility model wastewater treatment equipment uses integration apparatus, it is suitable for the materializing strategy of various variety classes complexity waste water, in the case of waste water type and water quality condition occur bigger deviation, remain to reach the expection purpose of design, and Automatic Control operation can be realized, easy for installation, put into operation fast, floor space reduces.This device greatly strengthen the reliability of all kinds of Waste Water Treatment, improves effluent quality, compared with prior art, has a following technique effect:
One, the setting of chemical reaction zone, the adaptability that waste water is processed by equipment is greatly enhanced, the conventional treatment effect can be only achieved through two stage treatment or multistep treatment, this equipment can disposably be removed, and decreases equipment investment, operating cost and floor space；
Two, FLOTATION SEPARATION pond is provided with contact chamber, flash trapping stage pond, aerosol filtering area, the second-order separation pond, be equivalent to secondary air-floatation separate, additionally flash trapping stage pond is provided with precipitation bucket, compared with conventional air supporting, there is obvious advantage, conventional air supporting water inlet float is less demanding in 1000mg/L, and this equipment water inlet float reaches as high as then 10000mg/L；Conventional air supporting is only applicable to oily waste water or float proportion is less than or is slightly larger than in 1.0, this equipment is not only applicable to oily waste water or float proportion is less than or slightly larger than in 1.0, the suspended material contrasting more than 1.0 or heavy oil etc. also have the treatment effect being not less than sedimentation tank；Conventional air supporting is to suspension class material clearance typically below 75%, and this equipment may be up to more than 95%, substantially increases water outlet quality；
Three, efficient air-floating segregation apparatus of the present utility model, under the conditions of the equal process water yield, prime dosing can reduce 1/3, under the conditions of equal chemical feeding quantity, processes the water yield and can improve 1/3, and the adaptability substantially increasing equipment also reduces floor space and operating cost.
