摘要

摘要: 污水近零排放是提高高新区水资源利用效率,推动产业结构调整升级的有效途径。然而,目前近零排放研究多关注单元技术的开发与改进,缺乏园区整体的近零排放方案,制约了近零排放在高新区的实践与推广。针对这一问题,以高新区整体为研究对象,在系统分析高新区典型产业的用水、排水特征的基础上,提出耦合单元处理-分质利用、企业处理-综合利用、园区处理-市政杂用、生态处理-生态回用、再生处理-工业回用的"五级处理-五级回用"园区污水近零排放模式,剖析该模式推广运行面临的智慧决策系统开发、水处理关键技术研发以及运行保障体系构建等关键问题,为高新区污水近零排放提供了可行、有效的途径。

Abstract: Near zero liquid discharge (NZLD) of high-tech zone (HTZ) is an effective way to improve water resources utilization efficiency and promote industrial restructuring and upgrading.However,current NZLD research mainly focused on the development and improvement of unit treatment technology,and neglected the systematic NZLD scheme for an integrated zone,which restricted the practice and popularization of NZLD.To this end,taking the whole HTZ as the research object,on the basis of systematic analysis of water use and drainage characteristics of typical industries,a five-level-treatment&five-level-reuse NZLD mode was proposed,which was the coupling of in-situ treatment-reuse based on water quality,enterprise wastewater treatment-comprehensive reuse,zone wastewater plant treatment-municipal use,ecological treatment-ecological water supplement,regeneration treatment-industrial reuse.Key problems of the mode were also analyzed,such as the construction of an intelligent decision system,the development of water treatment technology,and the establishment of an operation guarantee system.The novel mode would provide a feasible and effective way for NZLD of high-tech zones.
