摘　　要：根据工程确定的进水水质情况及出水水质要求,污水二级生物处理工艺宜采用生物脱氮除磷处理工艺。依据活性污泥工艺、生物膜工艺及膜生物反应器3大类生物工艺的特点,在满足地下式布置要求的前提下,结合工艺能耗、运行费用、操作管理等方面,选择切实可行且经济合理的生物处理工艺,是实现整个污水处理厂最佳工艺方案的保障。According to assured the water quality condition and water quality requirements in the project, sewage secondary biological treatment process used biological denitrification and phosphorus removal processappropriately. Based on the characteristics of three types of biological process, including activated sludge process, biofilm process and membrane bioreactor, on the premise of meet the requirements of the underground type, combined with the process energy consumption, operation cost, operation management, etc., choosed the feasible and economic and reasonable biological treatment process. This ensured optimum process scheme is to implement in the entire sewage treatment plant.
