Analysis on polluted condition and self-purification ability of Baiyangdian upstream water system

摘要：

Samples that are used to measure the value of PH, CODCr, TN, NH4+-N and TP are taken from the inland river of Baoding. And during the test, we find that the water quality of the inland river of Baoding does not reach the requirement of the five kind of water quality standard which said in the Environmental quality standards for surface water(GB3838-2002). Although each river section has the ability of selfpurification, the self-purification capacity of water body is dramatically lower than the speed of pollutant emissions.
