Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment, in particular to a sludge dehydration filter screen. Background Art

[0002] A sludge treatment method that removes water from flowing primary, concentrated or digested sludge and converts it into semi-solid or solid mud blocks. After dehydration, the moisture content of the sludge can be reduced to 55% to 80%, depending on the properties of the sludge and sediment and the efficiency of the dehydration equipment. Further dehydration of sludge is called sludge drying, and the moisture content of dried sludge is less than 10%. The main methods of dehydration are natural drying, mechanical dehydration and granulation. Natural drying and mechanical dehydration are suitable for sewage sludge. Granulation is suitable for coagulated and precipitated sludge.

[0003] At present, when dehydrating sludge, due to the high water content inside the sludge, in order to save the time of subsequent drying, filter plates are usually used for pre-dehydration. Since the sludge is in a flowing state, the filter plates are easily blocked during filtering and dehydration, resulting in low circulation efficiency of the sludge during dehydration.
