The sludge is sent to the "sludge dryer" through a screw conveyor, where it is stirred and mixed, and the sludge is gradually dried by heat conduction. Finally, the exhaust gas is discharged to the dust collector.
A large amount of lye is produced in the industrial production process. The cod value in the lye is high. If the lye is not treated in time, it will be difficult to operate the biochemical treatment tank in the sewage treatment process. At the same time, the waste lye contains a large amount of odorous substances and is easy to be polluted. serious1
