Description

Technical Field

[0001] The utility model relates to the field of filter boxes, in particular to a filter box for treating domestic sludge. Background Art

[0002] Domestic sludge refers to the sludge produced in urban residences and public facilities, which mainly comes from the process of treating domestic sewage in urban sewage treatment plants. The components of domestic sludge include organic matter, inorganic matter, microorganisms, heavy metals, volatile substances, ash, pathogens (such as bacteria, viruses and parasite eggs), toxic substances, etc.

[0003] Domestic sludge usually has a black or dark brown appearance, is fluid or cake-like, has a high water content, and has a foul odor. Due to the large amount of water contained in it, domestic sludge is not easy to handle and dispose of. Therefore, it is necessary to filter and dehydrate the domestic sludge through a filter box to reduce its volume and water content for subsequent treatment and disposal.

[0004] However, when the existing filter box is used, it is not conducive to replacing the filtering components in the filter box. After long-term use, the filtered domestic sludge is easy to clog the filtering components in the filter box, which will affect the working efficiency of filtering the domestic sludge.

[0005] Therefore, we propose a filter box for domestic sludge treatment. Utility Model Content
