The more economical and efficient sludge dehydrator

摘要

In the present invention, the sludge is introduced into the dewatering tank, and a ceramic separation membrane is formed inside the dehydration tank, and the sludge is transferred to the filtrate suction pipe through the suction pressure of the suction pump, and the remainder of the sludge excluding water in the ceramic separation membrane. Only the sludge solids, which are water, are adsorbed and filtered, and the filtered water can be discharged directly to a nearby river through the filtrate suction pipe. The dewatered sludge gravity falls to a storage unit formed at the bottom of the dewatering tank forming the upper gwanghyeop structure, and the dehydrated sludge is stored at the bottom of the filtration tank. In addition, in the water treatment process of the present invention, a dewatering device is installed in the middle of the transfer pipe between the bioreactors for the discharged sludge or the returned sludge, so that a separate pump or piping facility is not required, and only the operation of an automatic valve is used to operate the sludge tank as a batch. Sludge storage tank, sludge enrichment tank, dehydration filtration tank and other auxiliary facilities and coagulation mixing and chemical dewatering equipment are not required and are necessary for returning the returned sludge to the bioreactor. It relates to an economical and efficient sludge dewatering device characterized in that no expansion is required.
