In order to solve the defects of the sludge dewatering technology of the lime method in the sewage plant

the deep dehydration treatment of the sludge was optimized

and the new type of polymer modified conditioner sludge dewatering treatment technology was studied. The invention relates to a novel high-molecular-modified conditioning sludge treatment

which mainly comprises the following steps of modifying and conditioning the sludge by a FeCl3 and an organic high-molecular conditioning agent

performing pressure filtration and dehydration treatment on a plate-and-frame filter press

wherein the water content of the dewatered sludge can reach below 60 percent

and the addition of the dry matter in the treatment process is small

The influence of the heat value of the sludge is not high

and the dewatered sludge cake can be used for making bricks and burning

and the like

and the subsequent disposal requirements can be met. The use of new type of polymer modified conditioner sludge deep The degree dehydration process can greatly reduce the amount of the conditioning agent and improve the processing efficiency of the single plate of the treatment equipment

greatly reduce the energy consumption and the drug consumption

and the quantity of the dry matter is small

the actual external transportation sludge amount can be reduced by about 1/3

and the final disposal cost of the sludge is greatly reduced.
