Background technology
Nitrogen is a very important pollution factor that causes body eutrophication and environmental pollution.Denitrogenation is a link very important in sewage treatment process.Traditional biological denitrification process, is first under aerobic condition, and ammonia nitrogen is oxidized to nitrous acid nitrogen by Nitrosomas, and then nitrous acid nitrogen is further oxidized to nitrate nitrogen by Nitromonas.Under anoxia condition, nitrogen as nitrate or nitrite is reduced into gaseous nitrogen by denitrifying bacteria subsequently.
Biological denitrification needs organic carbon source as electron donor, and along with environmental pollution and eutrophication problem constantly increase the weight of, for the processing of some nitrogenous effluents, carbon source deficiency is the subject matter that affects denitrification effect.Carbon source used generally has three classes: additional carbon, raw waste water carbon source and internal carbon source.Because the organic loading of municipal effluent is generally not high, therefore utilize the general TN clearance of Prepositive denitrification technique of former water carbon source not high.If further improve nitric efficiency, need additional carbon to carry out denitrification.
Nearest research is found, in biological denitrificaion process, bioenergy is internal carbon source by most of solvability substrate conversion, be stored in cell with internal carbon source (being mainly PHB form), in the situation that anoxia condition there is no additional carbon, the polymkeric substance storing can be served as electron donor, and denitrification process is carried out smoothly, improves the denitrification effect of system.Therefore, the denitrifying research carried out of internal carbon source storing for matrix is valuable, and less for the denitrogenation research directly storing by carbon source in Sludge System in research both at home and abroad, and substantially without the application of Practical Project.
