The Water Quality Pollution Research about the Yellow River and the Feng River System before the Yellow River Diversion Works

ObjectiveWe carried out water quality surveil-lance and research for the Yellow river and Feng river system.ResultsAccording to 《The standard of ground water enviornmental quality(GB 3838-88)》6 to evaluate the water system quality,the tested result shows that 19 indexes accord with water quality standerd-typeⅢ.Some indexes eg.NII3-N,NII2-N,petroleum, Fe,Mn,etc exceed the water quality standard typeⅢ.Observed 8 times surveillance results at every surveillance spots,the NH₃-N in the yellow river exceed 5.90 times than that of standard 4 times, the higest concentrationis 1.38 mg/L.NO₂-N does 0.67 times 2 times,the higest concentration is 0.22 mg/l.The petroleum does 10.40 times 5 times,the higest concentration is 0.57 mg/l.The above indexes exceed 0.05~111.5 times than that of standard on the surveillace spots of the branches of the Feng river.ConclusionThe water qualities of the Yellow river and Feng river are polluted seriously.As aliving driking water,the water should be carried out the living driking standard(GB 5750-85)and get rid of the pollution to supply living water to the citizen.
