Description
Technical field
The utility model relates to a kind of paper-making effluent advanced treatment and reclamation device, and is especially a kind of based on electricity flocculation and the waste water advanced treatment recovery device BAF technology, that effectively design at the paper-making effluent features of pollution after secondary biochemical treatment.
Background technology
At present, paper-making effluent advanced treatment and reclamation technology mainly contains flocculation-air floating or precipitation technology, high-level oxidation technology, adsorption filtration technology, membrane filtration technique and Ecological Disposal technology etc.There are problems such as poor processing effect, sludge yield be big in flocculation-air floating or precipitation technology; Though high-level oxidation technology, adsorption precipitation technology and membrane filtration technique have comparatively ideal treatment effect to paper-making effluent, processing costs is high, does not have the engineering using value; The Ecological Disposal method is remaining organism in the degrading waste water further, but has that floor space is big, the soil salinization, easily grows problem such as mosquito, winter poor processing effect.Above technology just rests on lab scale, pilot scale stage because built-in problem does not all have the application of mass-producing, and reasonable economically, technical reliable paper-making effluent advanced treatment and reclamation technology is in blank at home.Simultaneously, the pulping and paper-making industry is as high water consumption industry, in short supply day by day along with water resources, water of productive use is arranged side by side with raw materials for production, become an important factor of restriction enterprise development, economically viable paper-making effluent advanced treatment and reclamation technology has the vast market demand in the pulping and paper-making industry.
Summary of the invention
Technical assignment of the present utility model is at above weak point, and the paper-making effluent advanced treatment and reclamation that a kind of system stability is good, processing costs is low, treatment effect is good device is provided.The technical scheme that its technical problem that solves the utility model adopts is: the utility model is mainly by being connected in twos by pipeline successively between water collecting basin, electric flocculation basin, reaction tank, settling tank, distribution reservoir, BAF pond, sterilization pool, water reservoir, the strainer; Lift pump is set in the water collecting basin; Gas blower connects the BAF pond; The backwashing pump import is connected with water reservoir, and outlet connects the BAF pond; On the pipeline topping-up pump is set between water reservoir and the strainer; The settling tank outlet is connected with sludge sump.The electricity flocculation basin adopts dc electrolysis device or pulse electrolysis device, and pole plate adopts carbon steel, cast iron, aluminium or other metal and alloy material.Reaction tank adds calcium hydroxide or calcium oxide.Settling tank adopts horizontal sedimentation tank, radial-flow sedimentation tank, tube settler or inclined-plate clarifying basin.Mix sanitary sewage in the distribution reservoir, mixed ratio is 5%～10%.BAF pond filtrate adopts gac, active sand, haydite or cobble.Sterilization pool adopts ozonization, disinfection by chlorine dioxide, ultraviolet disinfection or electrosterilization.Waste water is successively handled through electric flocculation basin, reaction tank, settling tank, distribution reservoir, BAF pond, sterilization pool, water reservoir and 8 workshop sections of strainer.The electricity flocculation basin reduces the content of organic pollutant in the waste water significantly, destroys the molecular structure of remaining organic pollutant in the waste water simultaneously, improves the biochemical property of remaining organic pollutant, and treating processes does not also increase the saltiness of waste water; The effect that reaction tank removes hardness in the waste water by adding calcium hydroxide in the mixed solution of electric flocculation basin water outlet, reaching, improves the flocs unit sedimentation function by adding calcium hydroxide, can be saved and add the high coagulant aids PAM of price; Settling tank is realized separating of suspension flco thing and waste water in the waste water; Distribution reservoir is introduced a certain amount of sanitary sewage, can effectively be that electricity flocculation back waste water replenishes nutrition sources such as nitrogen phosphorus and trace element, need not to add nutrition to the BAF system separately again, has reduced working cost; The BAF pond is by the pollutent in the highdensity biomass degrading waste water, the water quality of purifying liquid waste; Sterilization pool is killed the microorganism in the waste water, is beneficial to reuse; Water during water reservoir is temporary is used for the recoil of strainer front pump and the back flushing of BAF; The strainer suspended substance in the waste water that efficiently dams improves the water outlet quality, widens the reuse approach, and the strainer effluent reuse is in pulping and papermaking processes.
The utility model is compared with prior art, has following characteristics: one, the utility model design science is reasonable, and materialization and biochemical treatment are organically combined, and guarantees the good result of waste water advanced processing; Two, the utility model treating processes does not increase the saltiness in the waste water, has reduced simultaneously the indexs such as organic pollutant, suspended substance, hardness of waste water significantly, for the reuse of waste water is laid a good foundation; Three, the utility model need not outer Ensure Liquid by introducing sanitary sewage as nutrition source to the BAF system, saves processing costs; Four, the utility model has reduced the expense of waste water advanced treatment recovery significantly when guaranteeing water treatment effect.
