[0002] Urban wastewater treatment plants generate large amounts of sludge, which is characterized by high water content, foul odor, and heavy metals. my country widely adopts a combination of flocculation concentration and mechanical dewatering, but the resulting sludge is approximately 60-90 million tons with a water content as high as 80%. Mechanically pre-dewatered sludge (PDS) far exceeds the requirements for resource utilization. Due to the complex colloidal structure of sludge, low particle settling volume, and high compressibility of flocs, PDS is a colloidal soft solid gel, which is difficult to dewater deeply without pretreatment.
[0003] The existing technology has the following problems: The existing stacked filter press dewatering device requires batches of sludge to be fed and the multiple layers of sludge after feeding to be compressed and filtered. The continuity of the sludge filtration operation is poor and it is impossible to continuously dewater the sludge, resulting in low efficiency of the sludge filtration dewatering operation. To address these problems, we propose an ultra-high pressure stacked filter press dewatering device. Utility Model Content
