As we all know, the spiral sludge dewatering machine is widely used in the sludge dewatering stage in the middle and late stage of wastewater treatment. Before the sludge is dehydrated, the sludge concentration value of the sludge dehydrating agent must be added to cause the sludge to be separated into the internal filter press of the screw stacking machine, so that it will have a very ideal solution to the actual effect. The specifications of the superimposed spiral sludge dehydrator must be selected as a sludge dehydrating agent, because it can make the sludge report tight and the dedrying effect is very good. When the spiral promoting shaft is located in the outer field of the driving shaft, several fixed and movable polyimide films are relative moved, in which water filters out from the winding gap of the relative move to complete rapid concentration.

The sludge enriched by sludge dehydrant moves forward with the rotation of the screw shaft. Along the inlet and outlet of the filter cake, the tooth spacing of the screw shaft is slow, and the gap between the ring and the ring is also slow. The volume of the screw cavity becomes smaller. Finally, the dewatering of the sludge is completed.

So what kind of agent is added to make the actual effect of sludge dewatering stronger. The cost is lower. In order to have a stronger actual dedrying effect and lower usage, it is necessary to carry out the decision of pharmaceutical dosing sample based on the analysis and inspection of sludge. The amount of sludge dehydrating agent should be calculated according to the melting concentration, the common melting proportion of sludge dehydrating agent is 1/1000, and the sludge dehydrating agent aqueous solution is evenly added to the sludge according to the machine equipment, and the sludge is set up after solid-liquid separation.
