To restore these functions and promote rapid and sustainable economic and social development, river dredging projects are essential. River dredging projects can deepen and widen river channels, making the water clearer and improving water quality. They can also enhance the normal functioning of river channels, such as flood control and waterlogging prevention, and reduce the harm caused by floods.

This device is provided with a separation layer on the inner side of the filter cartridge to separate the filter holes on the filter cartridge surface and the sludge, so that the sludge does not clog the filter holes during centrifugal rotation, and the water and sludge are separated, thereby solving the problem of existing centrifugal dewatering machines in which sludge particles are thrown out at high speed, and some sludge particles will adhere to the filter holes, resulting in a reduction in the effective radius of the filter holes, affecting the separation efficiency in mud and water, and in severe cases causing the filter holes to clog, resulting in the inability to perform the separation process normally.
