Drying Technology
The subsidy methods for sludge disposal in different parts of our country are different, but they are all aimed at the long-term sustainable operation of environmental protection projects. Regarding the amount of subsidy, both the country and the locality use the sludge disposal method and the achieved effect as the measurement standard. Therefore, in the future, the comprehensiveness, the scientifically advanced sludge treatment and disposal, and the effective sludge disposal project will be more popular.
