引用土壤的净化能力与土壤环境客量概念，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应，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 concept of soil purification capacity and the amount of soil environment are quoted. The relationship between soil pollutant holding capacity, soil environmental purification capacity and soil treatment sewage level is discussed. The ecological effect of sewage entering the soil is taken into account, and the environmental effects of sewage entering the soil are also considered. Proposed sewage and anti-pollution measures: to protect the soil environment, rational use and development of soil self-purification capacity, the effective use of sewage to enhance land fertility. Improve the sewage irrigation methods and sewage irrigation system, give full play to the dual role of sewage irrigation in increasing production and protecting the environment.
