In order to explore the application methods and practical effects of agricultural Jiaosu in sewage treatment,and to explore the feasibility of using effluent for farmland irrigation,this study used the visualization software VOSviewer to comprehensively analyze 1 952 relevant literatures on agricultural Jiaosu in CNKI and Web of Science databases.The results showed that:1)The research directions of sewage treatment with agricultural Jiaosu at home and abroad mainly focus on the fermentation process of agricultural Jiaosu,effective components of agricultural Jiaosu,pollutant removal effect,Jiaosu addition and treatment conditions,environmental impact and application examples.2)Agricultural Jiaosu is a complex and stable ecosystem formed by anaerobic fermentation of microorganisms,which integrates beneficial microorganisms,organic acids,a variety of hydrolases and other active metabolic components.It can improve the degradation efficiency of pollutants in sewage.The treated sewage meets the standard of farmland irrigation water quality.3)As a low-cost and green preparation,agricultural Jiaosu has been gradually used in sewage treatment in recent years.Because domestic sewage contains mineral elements such as nitrogen,phosphorus and potassium,it has rich nutrients and irrigation water potential.The use of rural domestic sewage after Jiaosu treatment for farmland irrigation can effectively solve the problems of agricultural water shortage and rural domestic sewage pollution.To sum up,under the situation of global water shortage,as a new high-efficiency and low-cost way of sewage treatment and recycling,agricultural Jiaosu treatment of sewage is to build a model of returning domestic sewage and other resources to the farmland from the demand of agricultural sustainable development,which provides a new idea for the healthy development of farmland ecosystem.
