Device.
Background technique
Offshore pollution, frequent occurrence have resulted in catastrophic effect.To prevent and treat marine red tide, national departments concerned tissue
It implements the early warning of important sea areas red tide monitoring and demonstrative project of preventing and reducing natural disasters, strengthens red tide information management and the exceeded row sea of sewage
It manages, Sanya, Hainan Scenic Spot Area, or even require sanitary sewage disposal to reach five class water quality standard of earth's surface can just arrange sea.It grinds
Study carefully the origin cause of formation for showing red tide, ammonia nitrogen and phosphorus are the one of the major reasons of pollution.Therefore, how cost-effective control ammonia nitrogen is useless
Water pollution becomes the important topic of current environmental worker's research.Currently, water treatment technology is nothing more than physics, chemistry and biology
Three kinds of methods, what is generallyd use is biological method.It is considered from operating cost, biological method is minimum, and physical method takes second place, and works as dirt
Water pollutant biological method cannot degrade, and when physical method not can be removed, just use chemical method, the latter's operating cost ratio
The former wants high.
Existing denitrogenation sewage treatment has the disadvantage that and says on 1. stricti jurises that Nitrogen Removal Mechanism is still built upon biography
On the nitrification of system/denitrification theory, needed for denitrification 40% carbon source is only saved, this, which means that, also needs separately to add
60% carbon source.And carbon source selection and additive amount are difficult to control；It is exceeded to have added COD, has added that have lacked NH3-N exceeded, has increased simultaneously
Operating cost；2. in engineering practice, ammonia nitrogen is not in anaerobic effluent but not decline is increased instead, and nitration denitrification technique lacks
Point and insufficient early already known, theory are said very abstruse, and practical operation is troublesome, the control of reflux ratio difficulty.
