- Title:
- Study on the Compliance of Reclaimed Water for Agricultural Irrigation in the “Eco-Zone around the City” of Chengdu
- 摘要:
- 成都市规划了以城市中心公园带“环城生态区”为主的一系列城市生态农业景观体系，为城市发展提供绿色生态隔离空间的屏障。农田面积的增加势必加剧城市生活、工业与环境用水的矛盾，因此利用再生水进行农田灌溉是水资源可持续利用的有效途径。对再生水利用于成都市“环城生态区”农业灌溉的可行性和实施策略等进行了研究。系统地整理和分析了再生水处理厂的工艺、出水水质等，得出了研究区域再生水用于农业灌溉的可行性和风险点；区域主要再生水厂出水水质符合相关规范标准要求，出厂水水质相对稳定，但需要重点关注总氮、总磷、氯化物、无机盐和重金属等污染项目，防止该类污染物富集对环境造成不利影响；同时结合研究区域的水环境、土壤环境和农作物种类，提出了相应的实施策略和监管体系。
- Abstract:
- Chengdu has planned a series of urban ecological agricultural landscape systems dominated by urban central park “eco-zone around the city”, which provide green ecological barriers for urban development. The increase in farmland area is bound to aggravate the contradiction between urban life, industry and environmental water use, so the use of reclaimed water for farmland irrigation is an effective way of sustainable utilization of water resources. This paper investigated the feasibility and implementation strategy of reusing reclaimed water resources for agricultural irrigation in the “eco-zone around the city” of Chengdu. The technologies and effluent quality of reclaimed water treatment plant were systematically organized and analyzed, and the feasibility and risk of reclaimed water used for agricultural irrigation in the study area were obtained. The effluent quality of the main reclaimed water plants in the region met the requirements of relevant specifications and standards, and the effluent quality was relatively stable. However, it is necessary to focus on indicators such as total nitrogen, total phosphorus, chloride, inorganic salts and heavy metals to prevent the adverse impact of enrichment of such pollutants on the environment. In addition, corresponding implementation strategies and supervision system were proposed combined with the water environment, soil environment and crop species in the study area.
