Description

Combined type baffling water-treatment biological membrane reactor
Technical field
The utility model relates to water technology, relates in particular to a kind of technology of biological membrane of utilizing and waste water is carried out the bio-reactor of denitrogenation dephosphorizing.
Background technology
Improving constantly of the fast development of industrial or agricultural and people's living standard; it is serious that the feces of livestock and poultry of sanitary sewage, farmland discharging-irrigating water, trade effluent, aquaculture and large-scale breeding enters the urban water-body Eutrophic Extent that river course etc. causes; limited surface water resources is suffering pollution in various degree; water ecological setting worsens increasingly; species diversity is seriously damaged; not only affect mankind's orthobiosis, also restricted Economic development.Wherein the high-nitrogen waste water processing is a difficult problem always.
Due to biological restoration have advantages of economy, effectively, environmental friendliness, non-secondary pollution, and can realize the recycling that pollutes, be reliable method.In biological renovation method, algae, hydrocoles and waterplant, though or based on artificial swamp or the land system of waterplant, certain effect is arranged, its efficient is low, occupation of land is many, repairing effect is slow.And adopt method of microorganism to process, and effective, efficient is high, and biomembrance process especially wherein is higher to the removal efficient of organism in waste water etc., now has been widely used in the treating processes of water and waste water.Along with pollutent tend to gradually composition more complicated, easily accumulate difficult degradation and toxic effect is more long-term, thereby microorganism is just repaired and more seems important.And adopt the reactor process of active sludge to compare with biofilm reactor, and the former sludge creation amount in operational process is larger, and water quality is unstable, easily produces the operation problems such as secondary pollution.In biomembrance process, although ammonia nitrogen is removed in the biological filter and organic effect is relatively good, can make nitrate content increase in water, contain the high waste water of NO3-N and be discharged in environment, can cause secondary pollution again.
To the processing of nitrogenous effluent, many equipment and technology have been developed both at home and abroad.A kind of air-lift baffling inner circulation reactor and using method thereof are disclosed as Chinese patent 101386446, described inner circulation reactor is to be separated into advection district, top and baffling district, below by division plate (1) in casing, alternately stretch out traverse baffle (3) in the baffling district, baffling is offered material-feeding port (6) and monitoring and thief hole (8) in the district; Casing left hand external configuration oxygen charging pump (10), left side, aeration head (11) access baffling district.The using method of described device, treatment sewage input casing, regulate the Inlet and outlet water flow according to wastewater property, form the internal recycle baffling, from monitoring and thief hole (8) test dissolved oxygen, and regulate the aeration rate of oxygen charging pump (10) according to dissolved oxygen concentration, and form aerobic zone and anaerobic zone in the baffling district, emit unnecessary microbial film from discharge outlet (7); Treated water is discharged from water outlet (2) or discharge outlet (7).Realize wastewater biological denitrificaion and dephosphorization by microbial film, reactor and technique not only convenient operation but also reduce mud generation are beneficial to and apply.This reactor can't be processed the high water of dissolved oxygen, if in aeration, whole reactor, dissolved oxygen is too high, be unfavorable for denitrogenating, as aeration not, just can't move, aeration wherein can only be adjusted the dissolved oxygen of reactor, and biofilm biomass is few, power consumption is large, and the mud discharging mouth is many, therefore develops a kind of new-type bioreactor very necessary to wastewater treatment complicated and changeable.
Summary of the invention
The research major part that many technology and equipments are done is all to concentrate on nitrated this stage, and mineralized nitrogen is still to stay after nitrate to produce harm in water body.The utility model provides a kind of reactor that carries out high-efficient denitrification and dephosphorization for high-nitrogen waste water, pollutant characteristic for water body, adopt more novel biomembrane compounding baffling water-treatment biological membrane reactor, this reactor has the advantage of common biofilm reactor, the effect that has again obvious nitration denitrification can effectively reduce secondary pollution and other pollutent of nitrogen.
