摘要
根据湟水污染物现状调查监测,湟水流域每年向黄河输送的主要污染物为75 193 t。依据《地表水资源质量评价技术规程》(SL395—2007),采用单指标评价法,由湟水2010—2011年水质监测资料,得出湟水流域水功能区水质达标率为42.9%;采用季节性Kendall检验方法,对近5 a湟水水质站水质进行趋势分析,表明湟水流域水质整体状况无趋向。随着污水管网建设、污水处理厂的投入运行和河道综合治理,湟水流域的水质将逐步好转,各水功能区水质目标将逐步实现。
Based on the investigating and monitoring of the Huangshui River contaminants status,the main pollutants from the Huangshui River releasing to the Yellow River is 75 193 t every year.According to ＂Technical Specification for Assessment of Surface Water Quality＂（SL395-2007）,using the single index evaluation method and based on the 2010-2011 water quality monitoring data of the Huangshui River,the water quality standard-reaching rate of water function zones is calculated for 42.9% in the Huangshui River basin.Adopting seasonal Kendall examination method,this paper analyzed the water quality trend based on the last 5 year data monitored by water quality stations of the Huangshui River,and the result shows that the overall water quality has no trend in the Huangshui River basin.With the sewage pipe system construction,the sewage treatment plant put into operation and river comprehensive treatment,the water quality of every water function zone in the Huangshui River basin will be gradually improved and reach its objective.
