Lishui Economic Development Zone, the company R & D and manufacturing a set of high-tech equipment, can put 98% of the sludge to burn, the remaining 2% residue is used for making bricks.
The day before yesterday morning, from the National Engineering Research Center of pollution control, Shanghai, central and southern China Municipal Engineering Design and Research Institute,
Drainage Industry Association experts and business representatives gathered in Lishui to participate in the domestic first sets of comprehensive incineration sludge disposal system to promote the exchange, the first look at "artifact of sludge treatment in china".
In recent years, with the rapid growth of the urban sewage treatment capacity in China, city sludge production increased significantly. The sludge with high moisture content, large volume, difficult to storage and transportation. The common way of treatment is mainly simple landfill disposal of low level, or even illegal dumping, environmental pollution has caused great threat.
1 Deng Zhiguang, vice president of the central and southern China Municipal Engineering Design Research Institute introduced the amount of sludge generated by sewage treatment plant is about 0.15% - 1% of the volume of water treatment. The toxic and harmful substances in the sludge contains a large number of pathogens, parasites, pathogens, heavy metals and dioxins, radionuclides are difficult to degrade, and the sludge itself is smell, if improper handling can release the foul odor and other harmful pollutants, sludge disposal has become a problem that must be solved.
Comprehensive incineration sludge disposal system manufactured by Zhejiang Sanlian environmental protection machinery equipment Co Ltd R & D. The company is located in the Lishui eco industrial parks (Economic Development Zone), is a professional engaged in solid-liquid separation machinery R & D and production of high-tech joint-stock high-tech enterprise. At the Zhejiang
University and the Tongji University in Shanghai under the support of the enterprise for two years to develop a comprehensive incineration sludge disposal system. The system uses the existing incineration boiler, conveying equipment by increasing drying equipment and facilities, the use of incineration boiler flue gas heat, the moisture content of about 80% of the sludge drying to a certain extent, directly transported to the incineration boiler in direct combustion, to a depth of harmless, reduction, stable combustion, has wide adaptability. High combustion efficiency, load regulation scope and clean burning, its technology is simple and practical. The system can make 98% of the sludge treated by burning, the remaining 2% residue can be used for making bricks.
Wang Chunzhu on behalf of Tangshan Sanyou group said that their company sewage generated every day about 15000 tons, a large amount of sludge makes them a headache, could not find the right way. He said: "this trip to Lishui to see this set of comprehensive incineration sludge disposal system, our group finally found a solution."
