Description

Technical Field

[0001] The utility model relates to the technical field of filter press devices, in particular to a filter press device for biological sludge treatment. Background Art

[0002] Sludge filter pressing refers to a sludge dehydration method that uses positive pressure filtration to force sludge water to filter through the medium. Sludge treatment is the process of reducing, stabilizing and harmlessly treating sludge. The higher the degree of sewage treatment, the more sludge residue will be produced and need to be treated. For modern sewage treatment plants, sludge treatment and disposal has become the most complex and costly part of sewage treatment system operation.

[0003] At present, most sludge filter pressing processes rely on filter pressing devices, but most of the existing biological sludge treatment filter pressing devices generally have the problem of low treatment efficiency. During the treatment process, operators can only wait on site and cannot do other work at the same time. In addition, a lot of time is required for loading and unloading operations before and after the treatment, resulting in frequent equipment shutdowns, which further reduces the overall treatment efficiency.

[0004] Therefore, those skilled in the art provide a filter press device for biological sludge treatment to solve the problems raised in the above background technology. Utility Model Content
