Background

At present, municipal domestic sewage treatment plants basically treat sewage by using an activated sludge method, the process is mature, the treatment effect is stable, but the most serious defect is that a large amount of excess sludge is generated while treating the sewage, the sludge is generally rich in organic matters, germs and the like, and the cost for treating the excess sludge is high and accounts for about 20-50% of the operation cost of the sewage treatment plant.

Reduce the mud output from the source, can reduce later stage mud side treatment, processing cost by a wide margin, reduce the operation cost of sewage factory.

If a chemical (ozone, acid or alkali) treatment unit is added in the sludge backflow section, the residual sludge can be reduced by more than 40%, but the chemical treatment cost is higher, and meanwhile, the addition of chemical substances can cause toxic action on microorganisms in the water body, so that the normal operation of a water plant is influenced. Therefore, the problems that the sludge treated by the chemical process at present generally has more problems, such as difficult recycling, low sludge cracking rate, odor generation, operation cost and the like, can be seen. The ultrasonic sludge reduction technology is mainly used for reducing sludge through the cavitation action of ultrasonic waves.
