The high-efficiency high-pressure sewage treatment integrated system device is a mobile and efficient treatment device that integrates sludge conditioning, dosing concentration, pressurized filtration, and diaphragm pressing. This equipment has made significant improvements to the traditional box filter press, integrating multiple advantages such as low investment cost, high dehydration efficiency, small footprint, and simple operation and maintenance. This equipment is widely used in sludge dewatering, river dredging, oilfield drilling and other sludge treatment fields. It can significantly reduce the secondary pollution of sludge to the environment and achieve the goal of low-cost resource utilization of sludge.
