摘要
水体富营养化现象已成为人类面临严重的水环境问题之一 ,降低废水中氮和磷含量是防止水体富营养化的主要任务。软性填料淹没式生物膜序批式 (SBR)处理工艺 ,可使COD去除率达90 %以上 ,BOD去除率可达98 %以上 ,氮去除率75 %以上 ,磷的去除率可达90 %左右。是适合中小规模城镇生活污水脱氮除磷行之有效的技术之一。
The eutrophication of water is one of the serious water environment problems that the human being has to face. It is our main task to remove nitrogen and especially phosphorus from wastewater to prevent the receiving water from eutrophication and deterioration.The submerged biofilm sequerncing batch reactor process, COD、TN and TP removal efficiency are respectively reached, over 90%,75% and 90%.This treatment process is effective for the removal of nitrogen and phosphorus from demestic wastewater in midium and small towns.
