Description
Technical field
The invention belongs to city domestic sewage and process and regeneration field, be specifically related to the implementation method of the normal temperature nitrosifying quick start method of low ammonia nitrogen sanitary sewage and semi-hitrosation.
Background technology
Along with urbanization process is accelerated, water pollution is also day by day serious in recent years, and the body eutrophication that particularly sanitary sewage nitrogen phosphorus exceeds standard and causes brought serious disaster to people's production and life, and the pollution of nitrogen more becomes the most important thing of sewage disposal.And traditional nitration denitrification is faced with the problem that carbon source deficiency and denitrogenation and dephosphorization efficiency by using are difficult to synchronous raising when denitrogenation, cause water outlet N, P not up to standard.
Up-to-date scientific research shows ANAMMOX(Anammox) technique is the most economical biological denitrificaion approach of current sewage water denitrification, is one of most important reaction in nature nitrogen cycle approach.It is that microorganism be take ammonia nitrogen as electron donor under anaerobism or anoxia condition, nitrite nitrogen is electron acceptor(EA), the process that is nitrogen by two kinds of nitrogen transformation, compare with traditional nitration denitrification denitrogenation technique, ANAMMOX have oxygen-consumption low, without additional carbon, working cost is low and volumetric loading advantages of higher.No matter in economic, operation, or in decarburization effect, ANAMMOX technology all has higher using value and potentiality to be exploited.Yet this technique water inlet requires NO
