摘要
现今的通沟污泥处置多采用干化直接填埋的方式，会带来污染环境和浪费土地资源的问题。上海浦东新区选择采取预处理＋回收利用联合处理的新工艺来处置通沟污泥，先初步分离出大块物料，然后通过装置对污泥进行冲洗分离，冲洗干净的颗粒物（粒径为0．2—10mm）进行回收利用，污泥中的有机物质、有害物质经污水管道输送至污水厂处理，能够基本解决通沟污泥直接填埋对土壤的污染问题。
Nowadays, the disposal of dredging sludge utilizes the drying and direct landfill meth- od, which can cause some problems such as environmental pollution and waste of land resources. Shang- hai Pudong New District adopts the combined process of pretreatment and recycling to dispose of the dred- ging sludge. First, bulk materials are preliminarily separated, and then the sludge is washed out by means of separation device, and the washed particles with diameter of 0.2 to 10 mm are recycled. The organic matter and hazardous substances in the sludge will be transported to the sewage treatment plant through the sewers. The land pollution problems caused by direct landfill can be basically solved.
