Efficient deep dehydration system for sludge

Abstract

The invention relates to the field of sludge treatment, in particular to an efficient deep dehydration system for sludge. The efficient deep dehydration system for the sludge comprises a stirring type sludge pump, a sludge comprehensive response system, a conditioned medicament blending and adding system, a modified medicament blending and adding system, a flocculation medicament blending and adding system, a sludge screw pump, a membrane filter press, a clear water tank, a clear water pump and an electric control cabinet used for controlling all devices. According to the efficient deep dehydration system for the sludge, water supply plant sludge reduction can be effectively achieved, secondary pollution does not exist, the occupied area is small, the investment and operating cost is low, automation control is achieved in the whole process, and operation is safe and easy.

Description

technical field [0001] The invention relates to the field of sludge treatment, in particular to a high-efficiency deep dewatering system for sludge. Background technique [0002] At present, most urban waterworks draw water from surface water sources such as rivers, lakes, and reservoirs. The raw water undergoes processes such as coagulation, sedimentation, filtration, and disinfection to remove impurities in the raw water and produce water that meets the Hygienic Standards for Drinking Water. (GB5749-2006) of the finished water. [0003] While producing finished water, the waterworks also produce a large amount of sewage and sludge. The sewage mainly comes from the sludge discharge water from the sedimentation tank and the backwash wastewater from the filter, accounting for about 4% to 7% of the total clean water. At present, more than 95% of the waterworks in our country do not have sewage and sludge treatment facilities, and they are directly discharged into the water ...

AI Technical Summary

Problems solved by technology

[0005] 1) The period required for sludge treatment is long. On the one hand, the effective volume of the treatment structure is large, and the equipment configuration power is high or the number is large, resulting in high infrastructure costs for treatment facilities; on the other hand, the equipment runs for a long time, resulting in high power consumption;

[0006] 2) The concentration and dehydration effect of the current chemicals on the sludge from the waterworks is poor, resulting in a large dosage of chemicals and high operating costs during the sludge treatment process;

[0007] 3) The process route of the system is complicated, there are many equipments, and the operation and maintenance are inconvenient
