Description

Handle the device of the aerobic biologic membrane of low-concentration ammonia-nitrogen
Technical field
The utility model belongs to the water environment protection field; Concrete relate to a kind of device of handling the aerobic biologic membrane of low-concentration ammonia-nitrogen; Be specifically related to a kind of solid phase and liquid phase utilized and cultivate the mode that combines; Cultivation is used for the aerobic biologic membrane of the nitrated removal of low-concentration ammonia-nitrogen in the surface water body (such as the lake, river, reservoir and pond).
Background technology
Environment is the basis that the mankind depend on for existence and development, yet along with industriallization and quickening of urbanization process, excessive ammonia nitrogen gets into water body, severe contamination water body environment.Ammonia nitrogen is a kind of nitrogenous compound, is present in the water with ionic state and two kinds of forms of nonionic attitude.Natural and do not receive human river and lake of polluting, the level of nitrogenous compound is often very low, generally also is to be locked in the water body in the plant and animal body.Yet along with the aggravation of mankind's activity, because direct discharging, peripheral soil pollution of area source and the aquaculture of life and trade effluent, surface water body comprises that ammonia nitrogen concentration rises in lake and the river, has caused surface water body ammonia and nitrogen pollution problem.
Surface water body ammonia and nitrogen pollution ammonia and nitrogen pollution in industry and sanitary wastewater has obvious difference, and its difference mainly is ammonia nitrogen concentration.According to the difference of ammonia-nitrogen content, industry and sanitary wastewater can be divided into three types of high-concentration ammonia nitrogenous wastewater (ammonia nitrogen concentration is greater than 500 mg/L), middle concentration ammonia nitrogen waste water (ammonia nitrogen concentration scope 50～500 mg/L) and low-concentration ammonia-nitrogen waste water (ammonia nitrogen concentration scope 5-50 mg/L).According to the wastewater treatment emission standard, ammonia nitrogen concentration is not higher than 15 mg/L and gets final product qualified discharge in the water outlet.Yet ammonia nitrogen concentration with regard to low many, generally can not be higher than 5 mg/L relatively yet in the surface water body of ammonia and nitrogen pollution.
The environment and the health problem that at present ammonia nitrogen in the surface water body are caused are familiar with unclear.Chlorated ammonia nitrogen can cause the problem of smelling flavor above 0.2 mg/L in the tap water.For freshwater species, the scope that ammonia nitrogen concentration is in 0.53 to 22.8 mg/L in the water body it is generally acknowledged poisonous, will cause problem but problem is an ammonia nitrogen greater than 0.1mg/L, may damage the growth of freshwater fish eyes, the gill and internal organs.Up-to-date research shows that ammonia nitrogen concentration is in 1 to 4 mg/L will help blue algae growth and outburst.Therefore, even ammonia nitrogen concentration is not high in the surface water body, also need to administer.
Mainly contain electroosmose process, reverse osmosis method, air stripping method, selection ion exchange method and biological denitrificaion method etc. for the low-concentration ammonia-nitrogen wastewater treatment method; Wherein electroosmose process and reverse osmosis method cost are very high; Air stripping method generally can only be as pre-treatment or subsequent disposal means with the selection ion exchange method; Biological denitrificaion method economy, effectively is that utilization is the widest at present, the method for tool prospect.Present biological denitrificaion ratio juris is to carry out through these two separate processes of nitrification and denitrification, and wherein the mikrobe nitrifying process needs consume oxygen.Nitrobacteria is an autotrophic bacteria, utilizes inorganic carbon source and does not utilize organic carbon source, and the speed of growth is very slow, cultivates and difficulty all compare in increment, so nitrifying process is the critical limitation step that ammonia nitrogen is carried out a biological disposal upon.The desired bio-reactor of nitrobacteria suspension growth must have the effect of the very strong mud that dams, thereby has limited the processing power of reactor drum or needed complicated sludge settling and return-flow system.And nitrobacteria microbial film mode has solved the problem of disharmony in interior hydraulic detention time of biological treatment system and the sludge retention time control, when improving the treatment capacity of system, can not cause the nitrobacteria of slowly growth to be discharged with current.
Need to prove that cultivating suitable low-concentration ammonia-nitrogen removal aerobic biologic membrane is the comparison difficulty.For the microbial film that makes cultivation has high nitrification activity under the low-concentration ammonia-nitrogen condition; Ammonia nitrogen concentration equally should be very low in the nutrient solution; Have the active microbial film of the high-concentration ammonia-nitrogen of removal because the ammonia nitrogen in high density nutrient solution can be tamed out usually, activity was low when still ammonia nitrogen concentration was hanged down in removal, and speed is low.Use the nutrient solution of low ammonia nitrogen concentration to cultivate, success ratio is not high, because the bacterial classification of inoculation is easy to run off, causes the culturing process failure.Therefore, need a kind of can in the nutrient solution of low ammonia nitrogen concentration, turning out fast of utility model to be fit to the device and method that low-concentration ammonia-nitrogen is removed aerobic biologic membrane.
