摘要

摘要污水的使用减少了淡水灌溉用水。经过处理的污水通常被倾倒在淡水水体中，现在已被转移到农场灌溉。污水含有许多营养物质，减少了灌溉施肥的需求，这使其成为传统水源的有利选择，尤其是在缺水和城市周边地区。这种做法在一些地区被证明是一种福音，因为它随着土壤肥力和产量的提高而带来了有希望的结果。由于污水中存在重金属等某些污染物的毒性，研究人员发现污水对农业和环境有害。本文着重介绍了污水的组成及灌溉用水的适宜性。

Sewage Water: From Waste to Resource – A Review

Abstract The use of sewage water has curtailed the utilization of water from freshwater sources for irrigation purposes. The treated sewage, which was usually dumped into the freshwater bodies, has now been diverted toward farms for irrigation. Sewage water contains many nutrients and cuts the fertigation demand which makes it a favorable choice over conventional water sources, especially in water-scarce and peri-urban areas. This practice proved to be a boon in some areas as it presented promising results with increase in soil fertility and production. Due to the presence of toxicity of certain contaminants in sewage such as heavy metals, researchers have found sewage water to be detrimental to agriculture and environment. The article focuses on the composition of sewage water and the suitability of water used for irrigation.

期刊介绍： The Environmental Claims Journal is a quarterly journal that focuses on the many types of claims and liabilities that result from environmental exposures. The ECJ considers environmental claims under older business insurance policies, coverage and claims under more recent environmental insurance policies, as well as toxic tort claims. Exposures and claims from all environmental media are considered: air, drinking water, groundwater, soil, chemicals in commerce and naturally occurring chemicals. The journal also considers the laws, regulations, and case law that form the basis for claims. The journal would be of interest to environmental and insurance attorneys, insurance professionals, claims professionals, and environmental consultants.
