摘要:从再生水灌溉对土壤、作物、地下水和土壤斥水性4个方面简述国内外再生水灌溉的发展概
况和研究进展。已有研究表明:再生水灌溉对土壤肥力和土壤酶活性的影响尚未有定论;再生水对
农作物生长的影响尚有分歧;再生水灌溉对地下水水质具有一定的影响,并显著影响地下水水环
境;长期的再生水灌溉会引发土壤斥水性的产生,且土壤斥水持续时间与土壤有机质质量分数呈正
相关。目前存在的问题有:再生水灌溉对土壤和农作物的影响研究不一致,如何消除再生水灌水对
地下水和土壤斥水性的影响。认为由于再生水中含有作物正常生长的必要营养元素,若能克服再
生水灌溉存在的问题,可缓解淡水资源的压力和减少化肥的使用,避免环境的污染。

Abstract: Development progress and research advances in reclaimed water irrigation at home and abroad are
summarized according to the effects of reclaimed water on soil, crops, groundwater, and soil water repellency
There is no definite conclusion about the effects of reclaimed water irrigation on soil fertilizer and soil enzyme
activity, and reclaimed waters effect on crop growth is still controversial. Reclaimed water irrigation has a certain
impact on groundwater quality and a significant impact on the groundwater environment. Long-term reclaimed water
irrigation may cause soil water repellency, and there is a positive correlation between the soil water repellent
duration and soil organic matter content. Existing problems include the difference of opinions upon the effects of
reclaimed water irrigation on soil and crops, and determination of a way to eliminate the effects of reclaimed water
irrigation on groundwater and soil water repellency. Due to the presence of necessary nutrient elements for crop
growth in reclaimed water, reclaimed water irrigation could narrow the gap between the supply and demand of fresh
water resources and reduce the use of chemical fertilizer in order to avoid environmental pollution, if the problems
mentioned above can be overcome
Key words: reclaimed water irrigation; water resourees; research advances
我国水资源总量丰富,居世界第6位,但由于我资源的匮乏。用水量增加的同时也带来了污水排放
国人口基数大,人均水资源占有量仅是世界平均水量过大的问题,合理回收利用再生水可以缓解淡水
平的1/4左右,因此,我国是世界水资源极度匮乏的资源需求的压力,但我国再生水处理技术还尚不成
国家之一。近年来经济的迅速发展和人口的急剧增熟,有待进一步的提高。
长,极大地刺激了工农业及生活的耗水,加剧了淡水
再生水灌溉是指工业废水和生活污水经过无害
