Process principle

A sludge incubator is added into the traditional activated sludge wastewater treatment process, in which the sludge is used to deodorize odor-inducing components in the sewage  in situ. Meanwhile, the sludge of the secondary clarifier is returned to the inlet of the sewage structure, to adsorb and degrade the odor-causing components in the sewage of pretreatment stage, so as to reduce the odor emission concentration in it.

Application field

This method is mainly used in urban sewage treatment plants which use activated sludge process.
