宁波江北洪塘工业园区C区水质状况调查分析及防治对策

Investigation and Analysis of Water Quality in Area C of Ningbo Jiangbei Hongtang Industrial Park and Its Prevention and Control Measures

本研究主要对洪塘工业园区C区内的水体进行实地勘察和观测取样,并运用实验室相关方法,对取样水体的pH值、化学需氧量、溶解氧、氮磷、悬浮物、六价铬和叶绿素a等项目进行了检测。分析表明,洪塘工业园区C区内取样点水体的化学需氧量和氮磷等主要污染物检测指标平均值均属于V类水体,处于轻度富营养化状态,六价铬含量较正常水体超标2~3倍,存在污染风险。

This study mainly used field investigation and observation sampling of water bodies in Area C of Hongtang Industrial Park,and used laboratory methods to test pH,COD,dissolved oxygen,nitrogen and phosphorus,suspended matter,hexavalent chromium,and chlorophyll a in samples of water.The analysis showed that the average detection indicators of chemical oxygen demand and nitrogen and phosphorus of the main body of water in the sampling area of Area C of Hongtang Industrial Park belonged to the class V water body and were in a state of mild eutrophication,the hexavalent chromium content was two to three times higher than the normal water body,and there was a risk of pollution.
