Abstract
A method for treating wastewater in high-plateau and high-cold area, the wastewater and garbage leakage liquid being discharged through processes of physicochemical, biological and ecological steps. In the biological steps, carrier biological reaction device is employed, and by using immobilization technology of microporous biological carrier (WZT) and microorganism to improve the treating effect. In the ecological step, the artificial ecological wetland is employed. The method can treat wastewater especially wastewater in high-plateau and high-cold area with distinct effect because the critical technology of carrier biological reaction device and artificial ecological wetland can suit the climatic condition in high-plateau and high-cold area and it combines the physicochemical, biological and ecological steps organically, the wastewater treated can all reach the I class emission standard of country second category watershed.
Description
Affiliated field
The invention belongs to sewage treatment area, relate to particularly rubbish leachate treatment method of highland and severe cold areas sewage specifically.
Background technology
Administer sewage at present both at home and abroad and mainly contain methods such as biological treatment (as activated sludge process, anaerobic biochemical and biomembrance process etc.), materialization treatment process (as physics method, chemical method, physico-chemical processes etc.) and soil facture.The water temperature that activated sludge process requires is the suitableeest at 20～30 ℃, and for cold district, its decontamination effect improving will reduce greatly, in addition for the processing of high concentrated organic wastewater such as percolate, mud is very responsive to toxic substance, easily makes the miniaturization of mud flocs unit, and treatment effect degenerates.Could normally move after need cultivating domestication again to active sludge after the stoppage in transit, strengthen difficulty and the expense moved.The anaerobic treatment water outlet does not often reach emission standard, need carry out follow-up aerobic treatment, and its optimum temperuture is about 35 ℃, and when being lower than this temperature, processing efficiency reduces rapidly.Biomembrance process is subjected to weather effect bigger, and smell is big, and the filter tank fly is arranged, and operational flexibility is relatively poor, and the volume of equipment load is limited, and easy blockage phenomenon.The physics method needs bigger place and energy consumption, also needs the further processing of subsequent technique.Chemical method need consume a certain amount of industrial chemicals, can only be as the pretreatment technology of wastewater treatment.Physico-chemical processes remove to need certain device, also needs the solvent recycling of regenerating, and processing cost is higher.Because highland and severe cold areas has height above sea level, high and cold, hypoxemia, day and night temperature is big, sunshine is strong, air pressure is low, temperature is little climatic characteristic, direct or the single use of aforesaid method, not only implement and acquire a certain degree of difficulty, and all can not reach the ideal treatment effect.
Summary of the invention
Goal of the invention of the present invention is intended to overcome above-mentioned prior art defective, provide a kind of aforesaid method organically is combined into an integral body, get the length of the whole bag of tricks, effectively to the sewage of highland and severe cold areas particularly percolate handle, make water after the processing can reach the method for two class waters first discharge standards.
Technical scheme of the present invention is that this method comprises materialization step, biological step and ecological step.Sewage or percolate are successively through row discharging again after the processing of materialization, biology and ecological three steps;
Wherein materialization step is mixed in wastewater equalization pond for collecting sewage, regulate concentration of wastewater, will regulate mixed sewage and introduce the aeration stripping pond, Xiang Chizhong adds alkali control pH value, carry out the aeration stripping ammonia nitrogen, the sewage after the materialization step process enters biological step;
The technical process of biological step is: SBR (sequencing batch active sludge)---carrier organism---MBR film-biology---biological activated carbon, promptly in biological step, sewage passes through the processing that enters next step again after the processing of sbr reactor pond, carrier organism reactor, flocculation-air floating pond, MBR film-bioreactor and biological activity carbon decoloring device successively, in sbr reactor pond, carrier organism reactor, sewage carries out nitrification and denitrification, anaerobism and aerobic reaction, reduces COD, BOD loading; The effect in flocculation-air floating pond is the amount that reduces SS by flocs unit, and in the MBR film-bioreactor, hardly degraded organic substance is filtered, and free bacterium is trapped; Mainly carry out decoloring reaction in the biological activated carbon device, remove colourity, the sewage after materialization, biological step are handled finally enters ecological step and carries out further degradation treatment;
Ecological step adopts the artificial ecology wetland, and sewage enters in the artificial ecology wetland, and by the root system of the plant planted on the wetland and the rhizosphere microbial film of formation, organism, inorganics are absorbed and remove; For adapting to the highland and severe cold areas weather, the plant of artificial ecology wetland plantation is a highland and severe cold area waterplant Scirpus tabernaemontani, plants such as reed, fragrant plant thatch and Canna generalis Bailey; In the carrier organism reactor, adopt micropore bio-carrier (WZT) and microbial immobilized technology, the engineering complex microorganism is fixed in the carrier; WZT is the organic polyurethane foam of polymer, is the irregular mesh structure, and voidage 98% has the reactive functional group of static, can the active adsorption fixation of microbe, and microorganism and biological enzyme can not run off, improve wastewater treatment efficiency; Microorganism in the carrier organism reactor is a GCM30 microbial project composite bacteria, and it consists of EM+PSB+B350H+B110H, and wherein EM contains photosynthetic bacteria, milk-acid bacteria, yeast, acetic bacteria, actinomycetes; PSB is a swamp Rhodopseudomonas; B350H is the energy facultative type bacterium of decomposing protein, fat, carbohydrate and hydrocarbon polymer rapidly; B110H be can be in water the nitrifier of cracked ammonium rapidly.Its bacterial classification source is: EM buys from Jiangxi Province providence biotechnology development corporation, Ltd.; PSB buys from Sichuan Kang Di trip high-tech Industrial Co., Ltd.; B350H, B110H are that three safe square coenocorrelation technology ﹠ development Co.s buy from Beijing; Its microbial project composite bacteria proportion of composing is EM: PSB: B350H: B110H=2: 3: 4: 1.
Sewage water treatment method provided by the invention, wherein the flora in the carrier organism reactor is cultivated, is tamed through suitable the giving birth to of highland and severe cold areas severe winter, have water-fast amount, water quality, toxicity, soda acid, cryogenic impact capacity, can under the aerobic anoxic condition, carry out a series of biochemical reaction.Adopt porous carrier and microorganism curing technology in the carrier organism reactor, can improve the microorganism concn of wastewater treatment, keep high-efficiency strain concentration advantage, improve processing efficiency, shorten hydraulic detention time, reduce sludge yield, prevent sludge bulking.Microorganism is by immobilization technology, and energy is growth and breeding fast, forms diversity and the relative stability of microorganism, improves the organic broad spectrum of biological removal.Because gordian technique carrier organism reaction unit and artificial ecology wetland can adapt to the weather condition of highland and severe cold, whole in addition invention organically combines materialization, biology, ecological step, thereby to sewage particularly the sewage disposal of highland and severe cold areas have significant effect, wherein the clearance through sbr reactor pond COD reaches 70%, clearance through carrier organism reactor COD reaches 90%, reach 70% through artificial ecology wetland COD clearance, after above steps was handled, various sewage all can reach national two class waters I level emission standards.
