Sewage scum removal device and use method

Abstract

The invention discloses a device for removing scum from sewage, which includes a fishing device, a pretreatment device and a compacting device. The fishing device includes a sewage pipe and a lifting device. Inside the pipe, the top of the bobbin is closed, and the pipe wall inside the sewage pipe is connected with the inner wall of the sewage pipe, and the bobbin is located on the pipe wall inside the sewage pipe, and small holes are uniformly opened on the pipe wall inside the sewage pipe, and the bobbin is located in the sewage pipe. Part of the side close to the water inlet direction of the sewage pipe is provided with a feed inlet, the top of the bobbin is connected to the discharge port, and the inside of the bobbin is provided with a spiral blade, and a lifting motor is installed on the top of the bobbin, and the lifting motor drives the spiral blade . The invention can effectively remove the scum, not only greatly reduce the labor intensity of personnel, but also can recycle the scum, improve the quality of the environment, especially ensure good air quality.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage scum removal device and a use method. Background technique [0002] With the development of urban construction and the continuous improvement of people's living standards, the amount of urban sewage is increasing day by day. In order to protect and clean water sources, various cities and towns generally build sewage treatment plants, which process tens of thousands to millions of tons of sewage every day. Although this part of sewage is filtered by coarse and fine grids to remove debris, some fine debris and organic matter in sewage will flocculate into agglomerates and float on the water surface during the process of aeration oxidation or anaerobic fermentation. Watch, and emit harmful gases such as dioxins during the process of continuous oxidation in contact with air, affecting the quality of ambient air. Between the aeration grit chamber and the sedimentati...
