During the operation of the municipal sewage treatment plant, sewage treatment is mainly determined by reducing the volume reduction of the sludge. The entire process unit is referred to as a sludge treatment harmless process. Sludge treatment includes sludge concentration, dehydration, and digestion. The sludge-treated sludge or sludge product has a natural or artificial method to enable the final disposal of the sludge, which can achieve long-term stability and reduce the ecological environment without adverse effects. Sludge disposal, including land use, landfill and incineration, and comprehensive utilization.
Haiqi sludge coupled biomass：
The pyrolysis gasification treatment technology utilizes the heat of the sludge itself, and combines a small amount of cheap biomass fuel to dry the sludge as a heat source, thereby greatly reducing the cost of sludge drying. The most costly part of sludge treatment is in the dehydration stage. Through the treatment of pyrolysis gasification technology, the total exhaust gas generated by the process is 20% of direct incineration, and the harmful gas content is less than 10% of incineration, so the tail gas treatment cost is also greatly reduced, and it is easy to meet environmental emission standards.
