A kind of sludge/sludge dehydration equipment and dehydration method

Abstract

The invention relates to a sludge / sludge dewatering device and a dewatering method, which comprises a mud storage container, a three-dimensional dehydration assembly installed in the mud storage container, and a pressure plate arranged above the three-dimensional dehydration assembly and capable of moving up and down . A driving assembly for driving the pressure plate to move up and down and providing pressure to the pressure plate, the three-dimensional dehydration assembly includes a lower permeable plate located at the lower part of the mud storage container, and is arranged above the lower permeable plate And the upper water permeable plate detachably connected with the pressure plate, and the multiple vertically extending drainage elements connected between the lower water permeable plate and the upper water permeable plate, the mud storage container At least one side wall can be opened and closed. By setting the three-dimensional dewatering components as corresponding lower permeable plates and upper permeable plates, and connecting multiple drains between them, the sludge drainage channel is increased, and the pressurizing plate is pressurized through the driving component, Deep dehydration of sludge is achieved.

Description

Technical field [0001] The invention belongs to the field of sludge dewatering, and relates to a dewatering device, in particular to a sludge / sludge dewatering device and a dewatering method. Background technique [0002] At present, two problems in my country’s water environment have become increasingly prominent: (1) The newly-built or established sewage treatment plant processes a large amount of sewage and produces a large amount of sewage plant sludge; (2) A large number of polluted rivers and lakes The bottom mud is dredged and a large amount of silt is produced. The common feature of sludge and sludge is that it contains a lot of water. How to effectively reduce the quantity through dehydration has become an important technical requirement in the treatment of water environment in my country. According to relevant research reports, it is expected that by the end of the “12th Five-Year Plan” period, the annual output of urban sludge (with a water content of 80%) in my countr...
