摘要
以新泰市柴汶河各监测断面2012—2014年的水质监测数据为基础,研究了该河流水质污染状况,利用单因子污染指数法、平均值法、超标率和分担率对水中化学需氧量、氨氮、总磷、高锰酸盐指数、阴离子表面活性剂、氟化物、粪大肠菌群及挥发酚等8项污染物质进行评价,得出该河流水质主要污染物质是氨氮和化学需氧量,河流水质受污染状况随季节性和河流沿程变化明显:枯水期>平水期>丰水期,中游>下游>上游;同时对造成该河流污染的主要原因进行分析并提出相应污染控制对策。
The water quality of Chaiwen River was examined based on the water quality monitoring data of the river from 2012 to 2014.The single factor pollution index,average concentration,exceed standard rate and the share rate were applied to evaluate the COD,NH3 -N,total phosphorus,permanganate index,anionic surface -active agent,fluoride,class of Escherichia coli,and volatile phenol.The evaluation results showed that the major pollu-tants in the river were ammonia nitrogen and COD.The water quality changed in different seasons and sections. The water was more polluted in dry season,followed by normal river flow period and wet season.The water quality was worse in the up -stream than the down -stream.The water quality was the best in the middle -stream.The corresponding pollution control measures were put forward.
