Resource utilization of sludge drying

At present, the methods of sludge treatment in sewage treatment industry are usually centrifugal, pressure filtration and plate and frame machine dewatering, and the moisture content of sludge is usually 80%. The project realizes low-cost and resource-based drying treatment of sludge through specialized system. The core of sludge closed-loop heat pump low-temperature drying project is Haomai drying. After years of efforts, it has the advantages of small floor area, short construction period, low operating cost and

At present, the methods of sludge treatment in sewage treatment industry are usually centrifugal, pressure filtration and plate and frame machine dewatering, and the moisture content of sludge is usually 80%. The project realizes low-cost and resource-based drying treatment of sludge through specialized system. The core of the sludge closed-loop heat pump low-temperature drying project is the sludge closed-loop heat pump low-temperature drying machine developed by Haomai drying Co., Ltd. after years of efforts, it has small floor area, short construction period, low operating cost and no impact on the environment. The project can be modified on the basis of the existing sludge treatment technology of sewage treatment plant. The water content of municipal sludge (moisture content 50% ~ 80%) is reduced to 20% ~ 30% after low-temperature drying treatment. The whole drying device is sealed, and no harmful gas is generated. After drying, the sludge can be reused for resource utilization, such as building materials utilization, power generation by mixed burning of thermal power plants, etc.
