城市非点源污染治理与资源化技术研究

Treatment and Utilization Technology of Urban Non-point Pollution

城市降雨地面径流同时具有危害性与资源性,解决城市非点源污染的问题,亦应将削减污染与资源化结合考虑。本研究根据南方地区包气带中土壤水丰富的特点,设计出一种新型小区雨水处理利用方法。通过工程措施的一级沉淀处理和生态环境的二级生化处理使雨水径流得到处理和利用,实现污染治理与资源利用协调发展。

Urban rainfall flow is not only non-point pollution source but also available water resource. Control of urban non-point pollution should consider combining pollution reduction with utilization of rainwater source. A new technique of treatment and utilization of residential area rainwater was developed based on the characteristics of abundant soil water within aeration zone in southern cities, which can treat and utilize rainwater by means of primary precipitation and secondary biochemical treatment, to coordinate the pollution control with utilization of rainwater source.
