Description
Technical field
The present invention relates to a kind of advanced treatment system and method.
Background technology
In recent years, along with industry and agriculture development, wastewater from chemical industry, a large amount of discharges and the chemical fertilizer of sanitary sewage etc., agricultural chemicals, a large amount of uses of weedicide etc., make the contaminated degree of surface water and Eutrophic Extent etc. day by day serious, the seasonal variation of water quality and quantity is remarkable, traditional coagulation, precipitation, filter, sterilization process is to ammonia nitrogen, micro-content organism, Dissolved Organic Matter, smell the control weak effect of taste etc., after processing, water outlet is difficult to meet the regulation of country to the relevant criterion of drinking-water quality, therefore, remove the ammonia nitrogen in water, organic micro-pollutants, Dissolved Organic Matter, smell taste etc. and become water-supply plant urgent need to solve the problem.
The high latitude area time length in winter is longer, and raw water turbidity is low, has obvious low-temperature and low turbidity feature, is subject to the pollution of micro quantity organic pollutant simultaneously, because of and belong to the category of micro-polluted water.Because the former glassware for drinking water of low temperature has higher viscosity, thereby in flocculation process, collision rate and the settling rate of de-steady colloid all can obviously reduce, in addition, in low turbid former water, impurity particle number is seldom and mainly that the small colloidal particle of size is main, its surface causes particle to have stronger electrostatic repulsion compared with high Zeta potential, further reduced collision rate between particle.Thereby traditional depositing technology is difficult to the former water of the reply low turbid heavily contaminated of winter low temperature.The pollution of biological sewage and trade effluent causes surface water eutrophication ubiquity, causes algal bloom.Because algae proportion is little, be difficult to sink, so traditional technology is difficult to be removed, most water factories adopt alga removalby coagulation, cross filtering algae, preoxidation removes algae and air floatation alga removing except algae, Microfilter except algae, adsorption of sediment precipitation.Adopt pressure air-dissolving air-float art breading low temperature and low turbidity water to obtain good effect, the flco of reporting to the leadship after accomplishing a task due to the sedimentation function of low temperature and low turbidity water formation exactly has good floating performance, algae proportion is little, its surface has again good hydrophobicity performance, therefore be easy to form with bubble adhesion the bubble flocculation zoarium that proportion is less than 1, therefore air-float technology is in giving water treatment, and especially low temperature, low turbid, heavily contaminated, eutrophication, high algae source water have good application potential.
Ozone BAC Technology is to grow up in the application practice of drinking water treatment, it takes first ozone oxidation, by charcoal absorption, and utilize the microorganism of activated carbon surface biology to carry out biological degradation to the pollutent of charcoal absorption, complete the adsorption function original position reparation of gac.Biological filter technology is mainly used in removing organic pollutants and nitrogen ammonia, current known removal nitrogen ammonia and organic effective and most economical feasible method, microorganism is attached to gradually on carrier under suitable external environment condition, under the sufficient condition of oxygen in water, there is aerobic oxidation effect, ammonia oxidizing bacteria on microbial film is finally oxidized to nitrate by ammonia nitrogen, and meanwhile, denitrogenation can occur to a certain extent in the existence of aerobic denitrifying bacteria.Organism in some heterotrophic microorganism oxygenolysis water on microbial film, is removed organic pollutant and micro-pollution in water, as oxygen-consumption, stink substance, Dissolved Organic Matter, atrazine, 2,4-D etc.Ozone oxidation or catalytic ozonation be mainly used in improving water quality Oranoleptic indicator, control algae, help solidifying, oxidation natural organic matter, control Chlorination Disinfection By-products, remove Micropollutants etc., part macromole organic pollutant in water is oxidized to small molecules pollutent, improve the biodegradability of water pollutant, improve the concentration of the inner nutritive substance in follow-up biological filter, can also provide sufficient dissolved oxygen for follow-up biological filter simultaneously, the amount reproduction that is conducive to heterotroph microorganism, improve biomass and biological activity, alleviate the competitive relation to dissolved oxygen between ammonia oxidizing bacteria and heterotrophic bacterium." ozone oxidation/catalytic ozonation-biological filter " technique has obtained approval in more water factory practical application.
Tradition rapid filter is as the last one important process operation entering before clear-water reservoir, under general employing to stream filtered model, filtrate adopts hard coal more, gac, quartz sand filter media or several filler compound use, but the particle diameter of selected filtrate is larger, filtrate is poor to the suspended particulate filter effect in water, to miniature organism in water, biological residual body and planktonic organism are as poor filtration effect such as Cyclops, biological penetration problem is more outstanding, although can kill after chlorination, but may there is naked eyes visible in final outflow water, water quality and water supply security are caused to disadvantageous effect.Membrane Separation for Water Treatment obtains applying more and more widely with its unique advantage in water treatment industry.But, in traditional membrane filtration application, owing to can not effectively preventing film to pollute, lack effective mulch film purging method, caused membrane flux continuous decrease, work applied pressure raises, and makes water production rate be difficult to maintain constant, system power consumption increases, and the maintenance workload of film system increases and reduce work-ing life.The applicant is through long-term exploration and actual combat, a kind of effective and easy immersion negative pressure film and upward flow fluidization biological filter coupled structure form have been proposed, to more effectively prevent, film pollutes, film wearing and tearing, and the film that forms science cleans, operation and management mode.
Meanwhile, urban human ground contradiction is increasingly sharpened, and the transformation of old factory, upgrading and novel waterworks construction are faced with the problem that cost of land raises.Therefore, must change traditional water technology and theory to adapt to the water quality standard of water source and the increasingly stringent of deterioration.
Existing most of water factory conventional treatment process upgrading adopts " coagulation-precipitation-front sand filtration-O3 contacted oxidation-activated carbon filter-rear sand filtration-sterilization-water supply " technical process more while being advanced treatment process, this remodeling method for setting up advanced treatment unit after original sand filtration technique, there is following problem: first, complex process, newly-increased capital construction area is large, drop into highly, be not suitable for some standby soil few or without the water factory of, economically underdeveloped area; The second, lower to high algae, low temperature, low turbid, high pollution, the complicated former water treatment effect of source of pollution; The 3rd, stereotyped, regional adaptability is poor, a little less than the emergency capability of water source burst Pollution.
