Description

technical field [0001] The invention relates to the field of offshore oily sludge treatment, and more specifically relates to a horizontal screw press type offshore platform oily sludge pretreatment device. Background technique [0002] The horizontal screw filter press sludge treatment and concentration system is to use the new horizontal screw filter press to optimize and upgrade the new generation equipment to centrifugally separate the oily sludge. The filtered sludge can achieve a moisture content of less than 80% in the wet sludge, which can greatly reduce the volume and floor space of the sludge, and provide a good pre-treatment for subsequent resource utilization. Moreover, there are generally problems in the sludge dewatering process such as high moisture content of sludge, high energy consumption, and difficult treatment of filtrate. Therefore, it is necessary to conduct research on sludge dewatering performance, sludge deep dewatering agent and process, and find ...
