[0002] Among all the issues concerning the treatment and disposal of excess sludge in sewage treatment plants, sludge dehydration is always the core and key. General mechanical dehydration can only achieve a moisture content of about 80%, which is far from meeting the requirements for further disposal. To this end, technicians have successively developed a series of deep dehydration processes such as ultrasonic treatment, electrodialysis treatment, oxidation treatment, and heat treatment. Among them, heat treatment is one of the most practical methods.

[0003] The existing direct filter pressing device for thermal hydrolysis sludge still has some defects. Most of them are not thorough enough during filtration, and the water removal rate of sludge is low, which reduces the use value of the device. For this reason, we propose a direct filter pressing device for thermal hydrolysis sludge. Utility Model Content
