| Abstract: | Based on investigation and laboratory test of the field soil quality in the sewage irrigation area and the Yellow River irrigation area in Baiyin city,the influences of sewage irrigation on the field soil quatity were analyzed.The results showed that those harmful substances,such as Cr,Cu,Pb,Zn,Cd,As,Hg,F etc,had exceed the content limit of the national standard and the tendency has been increasing year by year.In addition,the countermeasures for sewage irrigation control and polluted soil improvement have been preliminarily discussed. |
