| 摘 要： | 模拟试验表明，氨基酸厂废水可以在一定程度上促进旱坡地紫色土某些生态因子的改善，主要表现在该废水可以增加土壤氮素和有机质含量，改善土壤水分状况，降低土壤失水速率和极限失水率，但也存在氯、盐分的累积，以及铜、锌、锰、铅等重金属元素活性加强等危险，这些结果已从现场调查及采样分析中得到验证。

| Abstract: | A simulated experiment was conducted to de-termine the role of wastewater dixcharged from an amino-acidfactory in improving the characteristics of purple dryland soil. The results, which were consisted with the field investigationand analysis, showed that nitrogen and organic matter con-tents in the soil had been considerably increased;soil moisturecondition had been improved and water loss rate from the soilhad been decreased after the input of the wastewater. Howev-er,the negative effects as the accumulation of Cl iron and salt,increasing activity of the Cu,Zn,Mn,Pb and other heavy tnet-als were also observed in the experiment. These results werefurther confirmed with field investigation and sample analysis. |
