Sludge disposal problems are also on the rise. The illegal dumping, stacking and landfilling of the past cannot solve the current needs. The future direction is resource utilization and incineration. Depending on the characteristics of the sludge, it eventually flows into cement and is incinerated in power plants. Now, local government departments have clearly stipulated that the sludge moisture content of sludge production units cannot exceed 50% or 60%; The only way to solve this standard is to increase sludge conditioner sludge depth dehydration and sludge drying.

If there is no effective chemical conditioning and modification, the sludge can no longer be deformed after being squeezed to a certain extent, and it is difficult to combine the water pressure under great pressure. On the basis of effective conditioning, high pressure can speed up the dehydration rate and improve the dryness after pressing.

The sludge conditioned by the sludge conditioner is injected into the filter chamber of the filter press at a pressure of about 1.0MP, which is conducive to efficient filtration of free water in the sludge. The sludge accumulated in the filter chamber reaches the design capacity of the filter press and enters the filter press. High pressure crimping. The final dryness of the press dehydrated sludge is closely related to the effect of chemical conditioning modification, as well as the filling degree of the press chamber, the increase rate of press pressure and the retention time of press pressure.
