绞吸与板框压滤组合技术在河道清淤 工程中的应用.

The river sludge in Wujin District, Changzhou City has seriously affected the surrounding environment, and the treatment and disposal of sludge has become a major problem. In this project, the combined technology of cutter suction and plate-frame pressure filtration is used to effectively treat the dredged river sludge. The combined technology specifically includes environment-friendly dredging system, pre-treatment system, conditioning and modification system, dehydration and consolidation system, and tail water treatment system. The results showed that the river sludge was separated into sludge cake and tail water from the solids/liquid mixture, wherein the sludge cake met the requirements of GB/T 23485-2009 Standard for Sludge Disposal and Mixed Landfill in Urban Sewage Treatment Plants, and the tail water met the standard of Class V water specified in GB 3838-2002 Environmental Quality Standard for Surface Water, meeting the design discharge requirements, with good social benefits.
