上海市石洞口城市污水处理厂污泥干化焚烧工程(2)

烟气排出前通过半干法脱硫和布袋除尘器除

(GB18485-尘,参照《生活垃圾焚烧污染控制标准》2001)的排放标准排放

由于干化污泥燃烧特性接近褐煤,经过循环流化床焚烧炉现场试验,其焚烧特性良好,因此许多国内厂家均有能力配套,技术也相当成熟,采用国产的流化床焚烧炉。5　投资及运行费

本工程预计投资8000万元(含干化和焚烧设备、土建、自控及辅助设施),运行费用160元/t湿污泥(含水率为70%,并包含电费、药剂费、人工费、维修费等)。6结语

,做到了对城、减量化,并有一。其运行费用虽有所增加,但是低于垃圾焚烧的运行费用。

联合处理工艺尤其适宜于土地资源紧张、环境要求较高、经济较发达的城市选用。

申城进行二次供水设施改造

上海市目前共有屋顶水箱1017万只,泵房或水池

6294只,小区立管14486km。上海市计划到2010年

全面完成对居民住宅小区室内立管、水箱和水池进行改造的目标。对小区二次供水系统中屋顶水箱和地下水池的改造,主要采用防腐处理,使用不锈钢、环氧树脂等材质;立管改造主要有更换管道和清管涂膜两种方式,以确保二次供水水质。
