污泥处置翻译1014.pdf

西安水务集团污泥处置项目工作情况 Status of Sludge Disposal Project of Xi’an Water( Group) Co.Ltd 目前，我市污水处理能力快速提高。截止 2010 年底中 3 心市区建成污水处理厂8 座，污水处理能力达到114 万m /d， 3 实际处理量约85 万m /d，日产生含水率约80%的脱水污泥（以 下简称污泥）约 1000t。目前，水务集团管理运营的污水处 理厂3座，分别为第三、第四和第五污水处理厂，污水处理 3 3 能力为60万m /d，实际处理量约45万m /d，日产污泥约500t。 由于污泥机械脱水后含水率仍然高达 80%，我市污水处理厂 污泥均未得到妥善处置。 Currently, the sewage wastewater treatment capacity of Xi’an city has been rapidly increased. By the end of 2010, eight (8) municipal sewage treatment plants have been built up and operated in the downtown and the total design sewage treatment capacity has reached 1.14 3 3 million m / d. About 850,000 m wastewater have been actual properly treated everyday, meanwhile daily produces approx. 1000t dewatered sewage sludge with about 80% moisture content (hereinafter referred to as sewage sludge). At present time, Xi’an Water (Group) Co.Ltd manages and operates three (3) sewage treatment plants ,named Xi’an No. 3, No. 4 and No.5 STP, of which the total Sewage 3 treatment capacity is 600,000 m /d,the actual treatment 3 amount is about 450,000 m /d and daily produces sewage sludge more or less than 500t. The sludge generated from the sewage treatment plants of Xi’an city has not been properly disposed, as the moisture content in the sludge after mechanical dewatering is still up to 80%. 浓缩了污水中大部分污染成分的污泥是由多种微生物 形成的菌胶团及其吸附的有机物和无机物组成的集合体，含 有病源体、重金属和持久性有机物等有毒有害物质，未经有 效处理处置，极易对水体、土壤和大气造成二次污染，直接 威胁环境安全和公众健康，使污水处理设施的环境效益大大 降低。 Concentrated the most amount contaminants of sewage water, The municipal sludge was kind of very complicated mixtures formed by var
