依据不同废水来源(城市/工业废水、养殖废水(水产养殖废水和家畜养殖废水)),综述废水灌溉最新研究进展。比较不同废水灌溉可能产生的环境和健康风险后,提出处理后的家畜养殖废水灌溉在提供植物生长所需养分的同时,不会产生城市/工业废水灌溉所引起的重金属、NO3-和药物等危害环境问题。展望了目前的研究重点应从城市/工业废水转变到家畜养殖废水方面,从环境科学角度转变到土壤和植物营养学角度,深入研究废水灌溉这种水肥耦合新模式对土壤、作物和环境的影响。
Based on different sources of wastewater (municipal / industrial wastewater, aquaculture wastewater (aquaculture wastewater and livestock farming wastewater)), the latest research progress on wastewater irrigation is reviewed. After comparing the possible environmental and health risks associated with different wastewater irrigation, it is proposed that the treated livestock wastewater can provide the necessary nutrients for plant growth without the hazards of heavy metals, NO3- and drugs caused by irrigation of municipal / industrial wastewaters Environmental issues. It is expected that the current research emphasis should shift from urban / industrial wastewater to livestock farming wastewater from the perspective of environmental science to soil and plant nutrition, and further study on the impact of wastewater irrigation on soil, crops and environment.
