AI Technical Summary

Technical Problem

The existing sewage sedimentation tank cannot effectively clean up the tar floating on the sewage surface, resulting in high frequency of blockage of sewage pumps and requires production and cleaning.

Method used

A sewage sedimentation tank is designed, including a box, an oil barrier, a first channel, a second channel and a third channel. The bottom wall sinking mechanism of the third channel realizes the precipitation of dust and impurities, and the oil barrier blocks the floating tar, separates sewage and tar, and facilitates cleaning of sediment and tar through the cleaning window.

Benefits of technology

It effectively reduces the frequency of sewage pump blockage, and easily and quickly realizes the separation and cleaning of sewage, dust sediment and tar, improving the efficiency of sewage treatment.

Abstract

The utility model discloses a sewage settling tank which comprises a tank body and an oil baffle plate, a water inlet and a water outlet are formed in the tank body, and a first channel communicated with the water inlet, a second channel communicated with the water outlet and a third channel used for communicating the water outlet end of the first channel with the water inlet end of the second channel are arranged in the tank body. The bottom wall of the third channel is located below the first channel and the second channel, the oil baffle plate is fixed to the top wall of the second channel, and the water outlet is located above the bottom end of the oil baffle plate. According to the sewage settling tank provided by the utility model, when sewage passes through the third channel, impurities in the sewage can be settled in the third channel due to the sinking of the bottom wall of the third channel, then the sewage flows out through the second channel and the water outlet, and when the sewage passes through the second channel, the impurities in the sewage can be settled due to the fact that the water outlet is positioned above the bottom end of the oil baffle plate. Therefore, tar floating on the surface of the sewage is blocked by the oil baffle plate and cannot pass through, so that the sewage and the tar are separated.
