太子河冰封期污染特征分析

Analysis on pollution characteristics of Taizi River during frozen period

以冰封期太子河本溪城区段河流为研究对象,通过现场调查采样分析各项污染物在水体和冰体中的含量及变化规律。结果表明,太子河水体中总氮含量相对较高;在冰封期,太子河冰体中的污染物向水体中发生迁移;水体中总氮含量、总磷含量与化学需氧量显著相关。

Taking Benxi urban section of Taizi River in icebound period as the research object,the content and change rule of various pollutants in water and ice body were analyzed through field investigation and sampling.The results show that the total nitrogen content in Taizi River is relatively high.During the icebound period,pollutants in the ice body of Taizi River migrate to the water body.The content of total nitrogen and total phosphorus in water was significantly correlated with the content of chemical oxygen demand.
