污水的土地处理中污染物迁移转化规律的试验研究

污水的土地处理是一种污水处理的生物工程技术,其原理是通过农田、林地和苇地等土壤植物的生物、物理、化学等固定与降解作用,对污水中的污染物实现净化并对污水中氮、磷等资源加以利用。污水土地处理技术应用于农田灌溉可有效减小污水对农田的污染。研究设计了一套垂直土柱用以模拟贾鲁河污水进入土壤后发生的污染物迁移转化过程,从而找出污水中有机污染物、氮、磷和重金属等污染物进入土壤后的迁移转化规律。

Experimental Research on Pollutant Migration and Transformation Rule in Sewage Land Processing

Sewage land processing is a kind of advanced bio-engineering technology,its principle is that: through the fixing and degeneration of biology,physics and chemistry between soil and plant in farmland,woodland,reed bed and so on.The pollutant in sewage is purified,the nitrogen,phosphorus and other resources are utilized.The sewage land processing technology application to the farmland irrigation may effectively reduce pollution of the sewage into the farmland.The test research designed a set of vertical soil column in order to simulate the movement of the pollutant from Jialu River to soil,and find out the migration and transformation laws of organic pollutant,nitrogen,phosphorus,heavy metals,etc.in the sewage into soil.
