Abstract

The invention relates to the field of environmental protection, in particular to a sludge filter press and a sludge treatment method. A sludge filter press includes a frame, a filter press component, a feeding component, a discharging component and an electric control component, wherein , the filter press components include a push plate that slides on the frame to perform compression, a thrust plate that is fixed on the frame to cooperate with the push plate to compress, and several series-connected pressure plates that are arranged between the push plate and the thrust plate Filter plate unit; the filter plate unit includes a metal back plate, a piston plate, a pressure ring and a spring arranged between the back plate and the piston plate; several filter cavities are formed between the filter plate units, and the filter cavity is pushed The pressure action of the plate and the elastic force of the spring have the function of changing the size of the cavity. The life of the metal back plate is longer, and at the same time, it can increase the feeding pressure and pressing pressure, improve the practical efficiency of the equipment, strengthen the sludge dehydration effect, reduce the use of chemicals, and greatly reduce the per ton processing cost of materials.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a sludge filter press and a sludge treatment method. Background technique [0002] When the sludge is dehydrated and its water content is less than or equal to 50%, the fluidized sludge will become a lumpy sludge with a low water content that is easy to transport, and it is difficult to produce microorganisms and bacteria after dehydration, which will not pollute the environment. Sludge filter press, as a kind of environmental protection equipment, is mainly used in the slag discharge process of sewage treatment. Its main function is to pressurize and dehydrate the sludge with high water content generated in the process of sewage treatment, making it a water content Lower mud cake for easier transport and landfill. For example, CN102126820A discloses a membrane filter press, which adopts a glass-limited reinforced polypropylene membrane filter plate, and injects water int...
