摘要
污水灌溉在国内外的许多地区都得到应用和发展,但盲目污灌带来了一定的后果。结合近年的研究成果综述了污水灌溉的益处和不科学的污水灌溉可能带来的不良影响,如对土壤、地下水、农作物和直接接触污水人员的影响。介绍了污水灌溉的主要技术措施。对我国来说,国情决定了污水灌溉是现实的选择,但存在着一些必须重视的问题,针对这些问题提出了建议以及对今后科研方向的一点想法。
Wastewater irrigation has been applied and developed in many countries. However, blind wastewater irrigation caused some aftermath.Combining with the research result of recent years, the paper summarized the advantage of wastewater irrigation,and the bad influence which unscientific wastwater irrigation may cause, such as on soil, groundwater,crop and the person who contacts wastewater directly. Main technique measures were also introduced. To our country, the situation of the country determines that wastewater irrigation is a realistic choice, but there are some problems to which must be attached importance. Suggestions to these problems and some ideas of the research direction of aftertime were put forward.
