Lucun sewage treatment plant sludge drying and resource utilization project

Sewage treatment scale: 200,000 tons /d
Sludge treatment scale: 240t/d (80% moisture content)
Owner: Sludge of Wuxi Drainage Company
Treatment process: bioleaching deep dehydration + high temperature aerobic composting
Production Date: May 2012 Cooperation Mode: BOT (franchise for 25 years)
Project overview: The scale of the project is to directly treat the sludge generated by 200,000 tons/day municipal sewage, which is invested and operated by our company in BOT mode. It was completed and put into operation in May 2012, solving the problems of high water content of municipal sludge, obvious odor and pathogenic substances, which affect the subsequent disposal and utilization of sludge. The sludge dewatering process does not need to add any desiccant, flocculant, such as lime, PAC, PAM, etc. The dehydrated sludge can be reused by aerobic composting.
