摘　　要：对加入浮动生物床处理后的生活污水的湖体富营养化程度进行了分析。通过选用具有代表性的参数总氮、总磷及叶绿素a对水体进行了研究,考察了水温、pH、浊度等对水体富营养化的相关影响,结合水质评价标准判断水体富营养化状态及浮动生物床处理系统的能力。结果表明:磷是水体富营养化的限制性因子,且湖水接近中等营养水平。Water eutrophication with addition of sewage treated by suspended carrier bio-film bed reactor was analyzed.By studying the representative parameters including total nitrogen,total phosphorus and chlorophyll-a,the correlation between temperature,pH,turbidity and chlorophyll-a was discussed.The eutrophication process and efficiency of suspended carrier bio-film bed reactor was evaluated according to water quality assessment standard.Results indicated that total phosphorus was the restrictive factor,and the water was close to middle eutrophication level.
