- Abstract:
- Sludge treatment is an important component of the water environment comprehensive improvement projects. The sludge here mainly involves river/lake sediment, sewer sludge, municipal sewage sludge, excrement dregs of septic tanks and slurry from construction projects. In the project of water environment comprehensive improvement in Maozhou River basin, the innovative pattern of “in-situ reduction + secondary treatment + resource utilization”and “six-party simultaneous project”work were adopted to sludge treatment. For the river/lake sediment, sewer sludge and slurry from construction projects, environmentally friendly treatment processes including debris separation, multi-stage sand extraction, sludge conditioning and plate-frame pressure filtration were applied to achieve resourceful utilization. The successful experience provides reference to similar projects at a river basin scale.
