| 摘 要： | 以鄂尔多斯市郝兆奎(HZK)生态城镇为例,考察了其灰水的水质特性,并提出了HZK生态城镇灰水集中处理工艺,分析了该工艺的可行性.结果表明:灰水的排放规律与居民的生活习惯有关,灰水处理系统的设计必须考虑到居民的生活习惯及当地的环境特点;HZK生态城镇灰水的阴离子表面活性剂浓度比混合污水的低,氨氮及总磷浓度与混合污水的基本相同,而COD及BOD5的平均浓度均比混合污水的高出30%以上;在灰水主体处理工艺前增加腐化池和调节系统作为前处理系统是十分必要的,腐化池对灰水中BOD5的平均去除率可达30%以上;HZK生态城镇灰水处理系统在满负荷运行时基本可以满足灰水处理的要求.

| Abstract: | Taking Haozhaokui(HZK) ecological town in Ordos City for example,the gray water quality characteristics were investigated.The gray water centralized treatment process in HZK ecological town was brought out and its feasibility was analyzed.The results show that the discharge rules of gray water relate with the habits and customs of the residents,and the people's living habits and the local environment characteristics must be take into account in design of a gray water treatment system.The gray water in HZK e... |
