摘要
结合实际的污水回用工程情况,根据目前处理工艺出水品质以及回用途径对水质要求的高低,把回用途径分为三大类,从技术经济、安全角度分析了主要的城市污水回用途径,认为近期城市污水回用途径主要应以水质要求较低而回用风险性小的工业冷却水、城市杂用和景观环境回用为主,回用于农业灌溉的水量在近期仍将有限,城市污水回灌地下水不适宜我国目前的国情。
The paper analyzed approaches of municipal sewage reuse from technical, economic and safety view, and proposed the approaches of municipal sewage reuse suitable for the situation of Chinese. It is concluded that the suitable approaches are industrial cooling water, water-scenery and urban municipal water. The water quantity reused in agricultural irrigation will be limited in the near future, it isn＇t suitable for the situation of Chinese that the municipal sewage reuse for groundwater recharge.
