摘　　要：由于我国总体水资源不足,随着国民经济的快速发展和人民生活水平的提高,灌溉用水不断被工业和城市生活用水所挤占,农业缺水日趋严重,不得不用大量的污水灌溉农田。国内外污水灌溉在规模上发展很快,由于污灌用水水质严重超标,并大多未经处理直接引用,其引发和加剧的土壤、地表水和地下水的污染日趋严重。为了科学地进行农田污水灌溉,当务之急是提高工业污水循环利用率和增强生活节水意识,减少污水排放量,大力推行农田灌溉污水预处理技术;使用EM等生物技术净化水体,改善灌溉水质和农业生态环境;建立健全农田污水灌溉的规范化管理体系;加强对污水灌溉的科学研究。Due to the shortage of water resources in China, along with the fast development of national economy and the enhancement of lives level of people, the irrigation water is unceasingly occupied by the industrial and the city life water, and the lack of agricul ture water is severely day by day, so the farmland has to be irrigated by using a great deal of sewage. In the world, sewage irrigation develops very quickly in the scale. Because the water quality of the sewage used for irrigating exceeds the allowed standard seriously, and the great mass of sewage is used directly without treatment, it has initiated the pollution on the soil, the surface water and the ground water intensifies severely day by day. For the sake of scientific sewage irrigation in farmland , the urgent work is to raise the industrial sewage circulation reuse ratio , to enhance consciousness of saving life water, to reduce sewage quantity, vigorously pro mote sewage pretreatment technology for irrigation in farmland , to use EM biological technology to purify the water body and improve irrigation water quality and the agricultural ecological environment, to establish the perfect farmland sewage irrigation standardized management system, and to strengthen the scientific research on sewage irrigatior.
