摘要
在概述了城市住宅小区污水特点及现状基础上,介绍了住宅小区污水处理的设计原则及常用工艺流程.在综合分析基础上,提出了CASS工艺处理城市住宅小区污水具有出水水质好、运行稳定、管理简单、占地少、产泥量低等特点,适合住宅小区污水的处理.最后详细介绍了CASS工艺的工作原理、工艺流程及出水回用的技术要点,CASS工艺的出水经过膜过滤和消毒处理即可达到中水回用的标准,为住宅小区污水处理及回用提供一种可供选择的工艺及配套设备.
The prime features of wastewater in residential quarters and the present situation of its treatment were introduced in this paper as well as the design principle and commonly used treatment progress of wastewater in residential quarters.It is pointed out that CASS technique has many excellences,such as that the treated water has good water quality,it runs stablely,it is easy to manage,occupies little area,produces low slob quantity and is suitable for the wastewater treatment in residential quarters.Finally,the principle and the process of CASS technique and key techniques of water reuse were introduced in detail.The treated water by CASS technique is further treated by membrane filtration and disinfection,the final effluent will be good enough to meet the requirement of the reuse standard.This process will be a candidate for the treatment and reuse of wastewater in residential quarters and provide an alternative technology and corollary equipment.
