Abstract

Reusing sewage water for crop irrigation becomes necessary due to freshwater scarcity, and groundwater depletion. Although the suitability of using treated sewage for crop irrigation remains a topic of argument among government authorities and policymakers. In light of this, this review article summarizes the present global situation and techniques for recycling and application of treated sewage water in agriculture. This paper highlights the environmental, health, and economic impacts of using wastewater as crop irrigation water, along with the advantages and disadvantages are carefully considered. The main objective of this study is to present a global scenario of treated wastewater being used to irrigate agricultural crops, along with the hazards associated with soil fertility, crop production, public health, and economic factors. This study compiled information on the best sewage treatment for agricultural irrigation disinfection practices. Eventually, database of laws and rules governing the use of sewage or wastewater in agricultural irrigation techniques for many countries throughout the world was created. As an environmental impact, effects on water bodies, quality of agricultural soil, microbial communities of soil, and growth of plants have been summarized. For the impact on public health, significant emphasis was given to the exposure to pathogens and heavy metals for both farmers and consumers. The potential risks of utilizing sewage water for human consumption have also been summarised. Focusing on summarizing economic impact involves financial investment and benefits to sewage treatment plants and farmers.

使用处理过的污水或废水作为农业灌溉用水-环境、健康和经济影响
由于淡水短缺和地下水枯竭,有必要将污水重新用于作物灌溉。尽管使用处理过的污水进行作物灌溉的适宜性仍然是政府当局和政策制定者争论的话题。鉴于此,本文综述了处理后的污水在农业中的回收和应用的全球现状和技术。本文强调了将废水用作作物灌溉水对环境、健康和经济的影响,并仔细考虑了其优缺点。本研究的主要目的是介绍一种用于灌溉农作物的经处理废水的全球情景,以及与土壤肥力、作物生产、公共卫生和经济因素相关的危害。这项研究汇编了有关农业灌溉消毒实践中最佳污水处理的信息。最终,建立了世界上许多国家在农业灌溉技术中使用污水或废水的法律和规则数据库。作为一种环境影响,综述了对水体、农业土壤质量、土壤微生物群落和植物生长的影响。关于对公众健康的影响,特别强调了农民和消费者接触病原体和重金属的情况。还总结了将污水用于人类消费的潜在风险。重点总结经济影响涉及到对污水处理厂和农民的财政投资和效益。
