The overall goal is that the harmless disposal rate of urban sludge reaches 90% by the year 2020, and the harmless disposal rate of urban sludge reaches 75% in other cities; county and city strives to reach 60% ". The sludge treatment market will be further developed as the next environmental hot spot following sewage treatment.

In the projects built by the five departments of China, importance is placed on the treatment protection of the environment, and a plurality of environment treatment systems are built, for example, 9 seats of a ballasted sewage treatment plant and 4 seats of a village sewage treatment plant are newly built aiming at the sewage treatment project of the Shanxi province, the Shangshi, luo, and the total treatment scale of the sewage is 7740m3/d. The engineering effluent quality of the sewage treatment plant in the Shangzhou area is discharged according to the yellow river A standard, and a sewage pipe network of 192.755km and related facilities are built in a matched mode.

In actual production practice, however, there are the following problems:

2. In the sludge container in the prior art, the sludge discharge opening of the centrifugal machine cannot be arranged too large, the sludge container below the centrifugal machine needs to be as large as possible, and the sludge has poor fluidity, so that the sludge cannot be uniformly accumulated.

3. The sludge in the prior art has large peculiar smell and causes environmental pollution. However, the existing centrifuges do not have deodorizing function.

5. The integrated device in the prior art cannot realize replacement and cleaning maintenance of internal components or media.

6. In the floating ball structure in the prior art, only for liquid application, the floating ball floats upwards to prop up the piston, and the liquid above the floating ball falls down, but the floating ball structure cannot be used for solid, and even if the solid is powder, a small gap (a gap between a ball rod and a cylinder) which is difficult to be yielded by the piston is formed.
