东辽河流域平水期污染现状及治理对策研究

在平水期对东辽河河段进行实地采样和检测,获得温度、pH值、溶解氧、化学需氧量、氨氮、总磷6项数据。结果表明:化学需氧量和氨氮含量有不同程度的超标,工业点源污染、城市生活污水污染得到一定的控制,但在部分地区仍然存在,农业面源污染成为污染物来源的主体,并呈加剧趋势。针对东辽河污染物来源现状,提出人工湿地技术用于污染治理的解决方案,对其可行性进行分析。

Pollution in the basin of east Liao River on normal water period and the research of control measures

From field sampling and testing in the east Liao River on normal water period,we measure 6 Indicators including temperature,PH,dissolved oxygen,chemical oxygen demand,ammonia nitrogen and total phosphorus.The results show that the content of chemical oxygen demand and ammonia nitrogen overweight by different level,that industrial point pollution and city sewage pollution have controlled,but it still exists in some areas,that agricultural pollution is the main pollutant source and shows increasing trend.Cons...
