An/OSBR process for phosphorus removal effect of different sludge load and nitrate concentration condition Tian Xiaoyan1,a , Wang Liang1,b Key Laboratory of Songliao Aquatic Environment, Ministry of Education, Jilin Architectural and Civil Engineering Institute, Changchun 130118, China a txy1317@163.com, b 709917980@qq.com Keywords: biological removal phosphorus;reaction temperature;COD load of sludge; anaerobic release phosphorus Abstract: Based on An / OSBR, the paper explores the different sludge loading and nitrate concentrations under the conditions of An / OSBR effects of biological phosphorus removal systems.The influent phosphorus concentration constant at 10 ± 0.5mg / L, in order to compare the end of the anaerobic and effluent TP concentration.The results showed that: ①With the increasing of nitrate concentrations , PAOs release phosphorus in the anaerobic reaction zone is decreased, nitrate appears to reduce the synthesis of PHB, which is due to PHB synthesis and denitrification
