Anaerobic wastewater treatment method for high strength wastewater with high nitrogen content

摘要

The invention talriaek food waste, livestock waste, leachate, and some industrial waste such as high concentrations of nitrogen and organic matter relates to the anaerobic treatment of the waste water system containing at the same time, in the process of anaerobic treatment of waste water in the anaerobic microorganism is an anaerobic waste water treatment process can be repeated by the anaerobic treatment in effectiveness by preventing the activity to decrease by the ammonium nitrogen to provide a system for anaerobic treatment of waste water containing a high concentration of nitrogen and the organic matter that can be completed at the same time it is an object. ; anaerobic treatment system of the organic substance-containing waste water with high concentration of nitrogen of the present invention, ; organics in the waste water are converted to methane gas and carbon dioxide gas as the primary bio jujongin anaerobic reactor that is converted to ammonium nitrogen are organic nitrogen in the wastewater; Primary effluent ammonia and adhesion growth aerobic reaction tank to reduce the expression levels of nitrite nitrogen and nitrate nitrogen to ammonium nitrogen conversion by using the nitrogen containing aerobic microorganisms in the anaerobic tank; Nitrite nitrogen and nitrate nitrogen is added to the reaction which is removed by reaction with the organic matter is converted to nitrogen under anaerobic conditions in the second anaerobic reactor is made occur at the same time, the waste water is introduced into the first anaerobic reactor and the aerobic reaction tank secondary Throughout the anaerobic reactor is treated in turn.
