Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a device for cleaning scum and sludge in a sewage treatment tank. Background Technique

[0002] In sewage treatment, after standing for a certain period of time, the sludge therein will deposit at the bottom of the sewage tank, and the scum will float on the surface of the tank. The traditional method is for operators to continuously fish the scum in the sewage tank and discharge the bottom sludge through the sewage discharge port at the bottom of the sewage tank. Due to the large range of the scum, it is time-consuming and laborious to clean; the number of sewage discharge ports is limited, the convergence of the sludge is not good, and the discharge efficiency is not high.

For example, the Chinese utility model patent with the application number CN201120537559.X and the name of sewage scum and sludge treatment device raises the bottom of the scum tank and cancels the pipeline returning to the lifting tank. According to the liquid level and the stock of scum in the scum tank, the hoist is opened in a timely manner, so that the scum in the scum tank can accumulate to a certain amount and then enter the sludge thickener to be pressed into mud cakes for discharge. By reducing the unnecessary backflow in the scum tank, the energy efficiency is improved, the scum concentration in the scum tank is increased, and the effective discharge of the scum is facilitated.
