Abstract

This application relates to the field of wastewater treatment technology, specifically disclosing a Fenton process and equipment for reducing sludge in desulfurization wastewater. The process includes a reduction tank, multiple sets of support rods and channel plates within the tank, an installation frame on the channel plates, a lifting cylinder mounted between the support rods, a sludge lifting frame mounted inside the lifting cylinder, a sludge separation mechanism on the installation frame, and an aggregation structure on the inner bottom wall of the reduction tank. The multiple support rods support the channel plates while also providing vertical guidance and limiting for the lifting cylinder. The aggregation structure enables automatic sludge aggregation without static sedimentation and concentration, reducing sludge caking at the bottom of the tank. The aggregated sludge enters the sludge lifting frame and is then dewatered by the sludge separation mechanism installed in the middle of the reduction tank. This achieves a continuous and compact process, effectively reducing the time and space required for each treatment step.
