Description

Technical Field

[0001] This utility model belongs to the field of oxidation ditch technology, specifically relating to a scum removal device for oxidation ditches. Background Technology

[0002] An oxidation ditch is an activated sludge treatment system. Its aeration tank is a closed ditch, so its hydraulic flow pattern differs from the traditional activated sludge process. It is a circulating aeration ditch with interconnected ends, also known as a circulating aeration tank. The earliest oxidation ditches were not built with reinforced concrete, but were earthen ditches with slope protection. They were intermittently filled with water and intermittently aerated. In this respect, the oxidation ditch was the earliest technology for treating wastewater using a batch process. The entire wastewater treatment process of the oxidation ditch, such as water inflow, aeration, sedimentation, sludge stabilization, and effluent, is completed within the oxidation ditch. The earliest oxidation ditches did not require separate primary sedimentation tanks, secondary sedimentation tanks, or sludge return equipment. Later, as the scale and scope of treatment gradually expanded, it typically adopted delayed aeration and continuous influent and effluent. The resulting microbial sludge was stabilized while the sewage was being aerated and purified, eliminating the need for primary sedimentation tanks and sludge digestion tanks, thus greatly simplifying the treatment facilities. Currently, during the operation of oxidation ditches, oxygen deficiency is easily caused by aeration and agitation, leading to the floating of scum. After floating, the scum accumulates and produces a foul odor, reducing the oxidation efficiency of the oxidation ditch. Therefore, a scum cleaning device for oxidation ditches is needed. Utility Model Content
