污灌增产效益及其对土壤环境影响分析

Study of Product Increasing Benefit by Sewage Irrigation and Its Impact on the Soil Environment

引用土壤的净化能力与土壤环境容量概念，探讨土壤纳污能力，土壤环境净化能力与土壤处理污水水平的关系，既考虑到污水进入土壤后的生态效应，也考虑污水进入土壤的环境效就提出排污和防污的相关措施，保护土壤环境，合理地利用和开发土壤的自净能力，有效地使用污水增强土地肥力，改进污灌方法及污灌制度，充分发挥污水灌溉在增产和保护环境的双重作用。

The relationships of soil contamination capacity,soil environmental purification capaci ty and sewage treatment level by soil are studied,based on the introduction of soil environmental capacity.With the consideration of both ecological effect and environmental impact when sewage entering soil,the corresponding measures are put foreward,which may protect the soil envoiron ment,use soil purification capacity reasonally,and utilize sewage water effectively to enhance soil fertility.Through improvement of irrigation method and schedule,the roles of sewage in raising the output of products and environmental conservation are fully played.
