Advance in Biological Pollutants in Agricultural Irrigation with Reclaimed Water
Rational and safe utilization of reclaimed water is one of the effective ways to alleviate the shortage of freshwater resources in farmland irrigation.Reclaimed water contains certain nutrient elements,but also contains certain harmful elements.Through literature review,this paper introduced in detail the research progress of reclaimed water utilization in agricultural irrigation from the aspects of definition and utilization of reclaimed water,types of biological pollutants,risk identification of biological pollution and risk control technology of reclaimed water quality in order to provide the references for the utilization of reclaimed water.The key future researches on reclaimed water utilization in agriculture were put forward,including evaluating the safety of reclaimed water utilization through long-term positioning tests,analyzing the half-life of antibiotics and other emerging pollutants in reclaimed water,formulating corresponding utilization standards,and developing low-cost and rapid sewage treatment technology.
