Traditional thermal hydrolysis has been widely used in Europe and the United States, which is an effective means of sludge and other organic solid waste treatment, and has been implemented in many cases in China. Aerobic thermal hydrolysis developed by the Tongji University team has been significantly improved in the following three aspects on the basis of traditional thermal hydrolysis:

First, more efficient: the traditional thermal hydrolysis is basically sequence batch production, the operation labor intensity is large, the energy loss is large in the production process, and the odor of the production workshop is large. The aerobic hot water can be continuous, fully closed, fully automatic operation, treatment efficiency is greatly improved, energy loss is small, and the production workshop has no odor.

Two, more energy saving: the traditional thermal hydrolysis of organic materials for thermal hydrolysis release relatively less heat, need to supply a large number of external heat sources. The aerobic thermal hydrolysis of organic matter by oxygen oxidation in water will release a lot of heat, at the same time, through the efficient energy recovery system design to recycle this part of the heat, can realize the heat self-sustaining reaction, save a lot of energy consumption.

Three, more thorough: traditional thermal hydrolysis for anaerobic reaction, just a simple cooking dissolution, on the sludge and kitchen waste in the organic matter of the wall breaking effect is limited, and produce refractory hydrolysate, to subsequent utilization and treatment bring great difficulties. Aerobic thermal hydrolysis, through the strong oxidation of oxygen, has a very good cell wall breaking effect, and decomposes into small molecular organic matter, good biodegradability, and can also be used as a supplementary carbon source for resource utilization, greatly reducing the subsequent treatment cost.
