摘要
通过对沙颍河水系水质的溶解氧(DO)、五日生化需氧量(BOD5)、氨氮、高锰酸盐指数、化学需氧量(COD)、总磷、氟化物、氰化物、水温、pH值、流速等11个参数,在2005年1月至2007年5月间的监测与评价,总结了近几年来沙颍河水质的变化规律,同时归纳总结了沙颍河水从1990年到2006年的几个重要水质参数的变化规律,在此基础上分析其原因,提出了有效的解决办法.
The present study has been undertaken to measure the water quality parameters： chemical oxygen demand, ammoniac nitrogen, dissolved oxygen , phosphorus , fluoride, cyanide, pH, velocity of flow, temperature of water, basis Five day biochemical oxygen demand, permanganate index of oxygen demand of the section（Zhou Kou（2） ） in the Sha-Yinghe river from 2005-01 to 2007-05. The study summarized the change regularity of the water quality parameters of Sha-Yinghe river quality from 1990 to 2006 years, and discovered that water quality deteriorated gradually year by year. The reasons on water quality were analyzed and the effective methods were put forward based on this foundation.
