氨基酸厂废水促进紫色旱坡地土壤生态建设的研究

The Role of the Waste Water Dispoxed form the Amino Acid Factory in Impro-ving the Purple Dryland Ecosystem

模拟试验表明，氨基酸厂废水可以在一定程度上促进紫色旱坡地的土壤生态建设，主要表现在该废水可以提高土壤的养分、抗旱性与抗蚀性，但也存在Ｃｌ、盐分的累积，以及Ｃｕ、Ｚｎ、Ｍｎ、Ｐｂ等重金属元素活性的加强等危险，这些结果已从现场调查及采样分析中得到验证。

Abstract The simlulated experimental were conducted to determine the role of wastewater dispose d from the Amino Acid Factory in improving the purple dr-yland ecosystem,The field investigation an d analysis results showed thefertility,drought resistance,and erosion resistance of the purple soils ir- rigated with the waste water h ad been enhanced considerably. Noticeably,the harms such as the accumulation of the Cl-and salt and the increase ofthe activities of the certain heavy metals w ere observed in the experiments.
