Description
Technical field
The present invention relates to a kind of Sewage treatment systems, be specifically related to a kind of multifunctional high-efficiency sewage treatment system with zero discharge.
Background technology
Along with industrial flouring day by day; Industry " three wastes " also produces thereupon in a large number, environment has been caused very big destruction, instantly; We also strengthen the protection consciousness of environment gradually; Effective processing of industry " three wastes " becomes matter of utmost importance naturally, and wherein, it is particularly important that the processing of industry and sewage just becomes.Mainly from the production process of factories and miness, owing to produce the different of used raw material and production process, the character of waste water is also different with composition for trade effluent.The waste water that contains a large amount of organic pollutants is from industrial enterprises such as food, plastics, oil refining, sugaring, chemical industry; The waste water that contains organism and inorganics simultaneously is from pharmaceutical factory, gas generating station, coke-oven plant, nitrogen fertilizer plant, rubber plant etc.; The waste water that contains organic/inorganic substance is from coal separation, material of construction, Iron And Steel Plant etc.; The waste water that contains heavy metal is from industry such as plating, mine, smelting, paint, pigment.
Common WWT mode is activated sludge process and physico-chemical processes, and Activated Sludge Process is a kind of most widely used waste water aerobic biochemical processing, and it mainly is made up of aeration tank, secondary sedimentation basins, aerating system and mud return-flow system etc.The active sludge that waste water refluxes bottom secondary sedimentation basins behind primary sedimentation pond gets into the aeration tank simultaneously, and through aeration, active sludge is suspended state, and fully contacts with waste water.Suspended solids in the waste water and gelatinoid be by activated sludge absorption, and the dissolved organic matter in the waste water is by the nutrition of the mikrobe in the active sludge as self-reproduction, and metabolic conversion is a biomass cells, and is oxidized into final product (mainly being CO2).The non-solubility organism need change into dissolved organic matter earlier, then just by metabolism and utilization.Waste water is purified thus.Purify back waste water and in secondary sedimentation basins, separate, upper strata water outlet discharging with active sludge; A mud part of separating after concentrating is returned the aeration tank, and to guarantee keeping certain density active sludge in the aeration tank, all the other are excess sludge, are discharged by system.
Physico-chemical processes is to utilize that extraction, absorption, IX, membrane separation technique are gentle operating process such as proposes, and handles or recycle the method for trade effluent.Mainly contain following several kinds: (1) extraction process.Water-immiscible solvent is dropped among the sewage, and pollutent utilizes the density difference of solvent and water by changing in the water in the solvent, and with solvent and water sepn, sewage is cleaned, and utilizes additive method to reclaim solvent again.(2) absorption method.Utilize porous solid matter, make one or more materials in the sewage be adsorbed on solid surface and remove.(3) ion exchange method.Utilize the ion exchange of ionite to replace the ionic state material in the sewage.(4) electroosmose process.A new technology that on the ion exchange technique basis, grows up has been saved the process with the regenerator regenerating resin.(5) reverse osmosis method.Utilize a kind of special semipermeable partition to hold back pollution substance soluble in water.Waste water extraction treatment method is to utilize extraction agent, makes the method for purification of waste water through extraction.According to a kind of solvent different substances is had this character of different solubilities, can some pollutent that be dissolved in the waste water be separated wholly or in part.In waste water, add water insoluble or be insoluble in the solvent (extraction agent) of water, some pollutent (extract) that is dissolved in the waste water is changed in the extraction agent at the interface through between extraction agent and waste water two liquid phases.
Mostly existing Sewage treatment systems is to handle according to a kind of method wherein the sewage of different properties or kind, and the treatment time is longer, handles not thoroughly, and environmental pollution is more serious.
Summary of the invention
The object of the present invention is to provide a kind of multifunctional high-efficiency sewage treatment system with zero discharge; Use this system can either handle the sewage that is suitable for Wastewater Treated by Activated Sludge Process; Also can handle the sewage that is suitable for using the physico-chemical process processing; Processing efficiency is high, and the sewage after the processing can reach emission standard, and the sewage sludge solid after the processing can utilize again.
