成都老式堆场底泥处理工艺设计及工程实践

Process Design and Project Practice for Sediment Treatment in Old Sludge Storage Site in Chengdu City

为有效解决成都市郊老式污泥堆场内的底泥淤积情况,通过技术比选和现场试验,最终采用新型淤泥处理工艺,在淤泥堆放现场引入高浓度泥浆专用离心脱水系统,对底泥减量化处理后外运,有效解决当地卫生安全隐患,避免二次污染。

To effectively remove a large number of sediments in the old sludge Chengdu City, a new sludge treatment technology, namely high-concentration centrifugal storage site in dewatering sys- tem was determined to be adopted after the technical comparison and the field test. The total amount of sludge can be minimized by this system, and then the dewatered sludge is transported out. The local health security and potential safety hazard were solved effectively, and the secondary pollution was avoi- ded.
