| Abstract: | Sewage and sludge are a kind of organic fertilizer that is rich in organic matter,nitrogen and other microelements,and it also contains pathogeny microbes and parasitic ovum etc.The paper analyzes minimization of nitrogen,consolidation of phosphorus,the pollution of ground water caused by nitrate,the changes of heavy mental during agricultural sludge.And it also deals with how to use sludge reasonably so that the waste can be changed into resources and make sustainable development of agriculture mode that featured with unification of economic benefit,environmental benefit and ecological benefit as well. |
