摘要
总结了近几十年来源分离处理技术在国内外污水处理、资源回收以及污水源分离的收集与输送系统等方面的发展,基于污水源分离的分散式处理系统,可以灵活地满足不同处理规模和水资源利用的要求,在资源回收利用上更加高效,日益受到人们的关注。认为污水源分离技术无论在污水处理效果、资源回收能力以及投资成本和运行维护方面,都更加适合当前的"资源-人口"发展形势。应将源分离技术与分散式系统相结合,根据不同的源分离程度合理选择处理系统的规模,使得污水处理后可以就近回用,减少长距离输送带来的成本,同时形成规模化的资源回收与输出,又能在一定程度上实现集中管理。
The development of source separation treatment technology in the field of wastewater treatment, resource recovery and collection and delivery system of wastewater source separation at home and abroad in recent years was summarized. Considering the flexibility to different scales and the requirements for water reuse and high efficiency of resource recovery, decentralized system based on source separation becomes more and more popular.Pointed out that the wastewater source separation system can satisfy the "Resource-Population Nexus" better on pollutants removal, resource recovery,as well as initial investment, operation and maintenance. The source separation should be combined with decentralized system, and select reasonable treatment scale based on different degree of source separation which would reuse treated wastewater convenient, reduce cost of long distance delivery,form large-scale resources recovery and output and realize centralized management partly.
