DU type activated sludge wastewater treatment is equipment using vacuum negative pressure as impetus to separate the solid and liquid. The filter district is arranged levelly to sequentially finish the procedure of filter, rinse, dry and regeneration of the filter cloth with high efficiency, high output, good rinsing effect, low moisture, agile operation and low repair cost. It can be used to separate solid and liquid in the fields of metallurgy, mine, chemical industry, papermaking, food, pharmacy and environmental protection, especially for dehydration of gypsum in the process of smoke desulfurization.

1. Annular friction belt is fixed between vacuum tank and rubber filter belt, to be sealed with water, lubricated and cooled so that the vacuum is airtight and reliable. This can maintain stable authenticity, lower the water content in the filter cake, and facilitate stabilizing operating process conditions. In addition, annular friction belt has a smaller friction resistance, and thus has a longer service life, easy and fast for replacement;
2. Air-cushion support or water-film support with closer rollers is adopted for the belt. Belt will run by floating on the support cushion, reducing resistance during running and prolonging the service life of rubber belt;
3. Adopting annular friction belt, it has a bigger tensile strength and longer service life;
4. Modular designing is adopted for the whole structure, which is flexible for installation and convenient for transportation and installation;
5. The automatic realigning device for air-bag filter cloth can ensure stable running of filter cloth;
6. Automatic liquid discharging and separating device or that of liquid column type is available in vacuum balance state, which can be flexible in achieving automatic liquid discharging of potential difference of liquid discharging of high potential difference for the vacuum belt filter, This can meet requirements for various operating conditions;
7. PLC is adopted for the control system while due consideration is provided for the design of interface technique with remote DCS control; It is possible to effect PID setting for equipment running, on-site and remote automatic control, and safety control and process monitoring for equipment running 

Now it has been widely used in the solid-liquid separation, such as metallurgy, mining, petrification, chemical industry, coal washing, paper marking, fertilizer, food, pharmacy and environment protection, as well as the industry of gypsum dehydration in the flue gas desulfurization.
