Description

technical field [0001] The invention relates to a sludge treatment technology in the environmental protection industry, in particular to a product technology of a vacuum filtration combined with electric dehydration sludge treatment system. Background technique [0002] Sludge dehydration treatment is an important task in the environmental protection industry. How to dehydrate a large amount of sludge generated in the process of treating industrial sewage and municipal sewage in an efficient, energy-saving and environmentally friendly manner has always been a major technical issue in the environmental protection industry. The traditional sludge dewatering technology mainly uses plate-and-frame or belt-type or stacked-screw-type or centrifugal-type dewatering machines to dewater sludge mechanically. The disadvantages are: 1) Low operating efficiency, and it is impossible to treat a large amount of sewage at the same time. 2) The dehydration effect is poor, and the moisture c...

AI Technical Summary

Problems solved by technology

The traditional sludge dewatering technology mainly uses plate-and-frame or belt-type or stacked-screw-type or centrifugal-type dewatering machines to dewater sludge mechanically. The disadvantages are: 1) Low operating efficiency, and it is impossible to treat a large amount of sewage at the same time. 2) The dehydration effect is poor, and the moisture content of the sludge after dehydration is still maintained at about 80%; 3) The cost of dehydration is high, not only to purchase a large number of expensive mechanical equipment, but also during the dehydration process. consumes a lot of energy

According to the characteristics of extremely low permeability and high organic matter content of sludge, as well as the principles and characteristics of vacuum filtration dehydration and electric dehydration treatment technology, the dehydration effect of sludge dehydration treatment using vacuum filtration dehydration or electric dehydration treatment technology is average; However, the combination of vacuum filtration dehydration or electric dehydration treatment technology and mechanical dehydration technology can significantly improve the dehydration effect of sludge treatment, but the treatment cost is higher than that of mechanical dehydration technology alone, and its economy is worse.
