沙河周-漯段水质变化规律研究

Temporal distribution regularity of water quality in Zhou-Luo reach of the Shahe River

通过对沙河周-漯段河水水质的化学需氧量、5日生化需氧量、氨氮、总磷、高锰酸盐指数、溶解氧、氟化物、氯化物8个参数在2004年1月-2006年5月的监测和研究,总结了近几年沙河水质的变化规律,并比较了不同断面的水质,找出了颖河汇入沙河时对沙河水质的影响.

The present study has been undertaken to measure and monitor the water quality parameters： Chemical oxygen demand , Five days biochemical oxygen demand ,dissolved oxygen , ammoniac nitrogen, permengemand index of oxygen demand , phosphorus, fluoride and chlorine of the two sections （Zhoukou （1）, Mamenzhashang） in Zhou-Luo reach of the Shahe River from 2004--01 to 2006--05. The study summarized the change regularity of Shahe River water quality in recent years,and compared the water quality form different sections, and examined the impact on water quality when Yinghe River flowed into Shahe River.
