区域尾水处置研究进展

A review on disposal of regional treated wastewater

基于水污染的区域化和流域性特点,提出了区域尾水的概念,并对其范围和内涵作了讨论与界定。通过综述国内外区域尾水处置的研究和实践,评述了区域尾水的三种控制模式的优缺点,认为要有效解决区域性尾水处置问题,必须根据区域的社会、经济、环境的实际情况,将人工处理、尾水分流与生态处理三种处置模式有机结合,通过整合与集成,建立区域性的尾水处置体系。根据水污染控制的工作程序和尾水处置的实际情况,提出“三级控制、三级标准”的尾水控制模式可能是建立系统契合、全过程控制的区域水环境污染治理的有效途径之一。

Based on the characters of water pollution in different regions and drainage areas, the concept of regional treated wastewater was put forward, with its scope and notion defined and discussed. Then the progresses of regional treated wastewater disposal were reviewed, and the advantages and disadvantages of three disposal methods, including artificial treatment, treated waste water diversion, and ecological treatment, were compared. Effective disposal of regional treated wastewater would not be realized only by combination of the above three based on the actual conditions of society, economy and environment, etc. Finally, according to the procedure of water contamination control and the actual condition of treated wastewater disposal, a model of triple control and triple standard was put forward, and it would be one of the most effective ways to realize regional water pollution remediation.
