Municipal sewage sludge is produced by the sewage treatment process of organic matter, microbial groups such as microbial sedimentation material and the floating surface of floating debris floating in the water, which contains a large number of pathogens, parasites, pathogenic microorganisms, dioxins and arsenic, Mercury, chromium and other toxic heavy metals. How to further deal with the sewage sludge generated by the world's environmental protection is a major problem in the field.

Since the 1990s, developed countries have put the disposal of sludge into the focus of environmental protection work. The traditional methods of sludge disposal mainly include sanitary landfill, incineration and heat utilization, new building materials and so on. The sanitary landfill is relatively simple in equipment requirements, but requires a lot of landfill sites and sludge transportation costs, but also prone to groundwater pollution and odor dissipation and other secondary pollution problems; incineration and heat utilization technology to take full advantage of the biogas generated Power plant, the energy self-sufficiency rate can reach more than 50%, but incineration equipment and operating costs are expensive, easy to cause air pollution, still left about 1/3 of the amount of solid inorganic matter. At present, most of the municipal sewage treatment plants in China can control the sludge after treatment to 80% water content, but this has been unable to meet the status of China's urbanization accelerated.

Conventional treatment processes and old-fashioned filtration equipment are no longer sufficient. To this end, I joint domestic companies, large municipal engineering companies and other partners, take the road of production and research joint innovation, the successful development of the depth of municipal sewage sludge drying needs of a new generation of pressure filter.

Features:
1) high production efficiency, each working cycle time in 1 to 2 hours;
2) after the treatment of the cake automatically peeling off, reduce labor intensity;
3) integrated design concept, the use of significantly improved after the environmental stench;
4) The treated sludge has a moisture content below 60% (the minimum data value is less than 40%), which can meet the sludge disposal requirements such as incineration and landfill, and realize multi-channel disposal of sludge.
5) with mature and reliable sludge conditioning technology with low operating cost of equipment to meet, including BOT, etc., including a variety of operating methods.
6) equipment investment economy, only the price of imported equipment 1/5.
