A kind of urban sewage treatment equipment

Abstract

The invention discloses an urban sewage treatment equipment, the structure of which comprises a treatment box, a sewage inlet pipe, a sedimentation structure, a partition, a treatment chamber, and a slag discharge pipe. The sewage inlet pipe is vertically installed on the left surface of the treatment box, and the sedimentation structure is embedded Installed on the inside of the treatment box. There are three partitions and welded with the inside of the treatment box to separate the treatment chamber. The slag discharge pipe is embedded and installed at the bottom of the front of the treatment box. The sewage inlet pipe is provided with a sewage inlet and runs through the treatment box. There is a slag outlet in the slag pipe and it communicates with the inside of the sedimentation structure; the sedimentation structure includes a channel, a barrier structure, a filter plate, an inner partition, and a sedimentation treatment chamber. The channel is located on the left side of the barrier structure and communicates with the sewage inlet. The invention sets up a sedimentation treatment chamber on the right side of the barrier structure, which facilitates sedimentation into the lower sedimentation chamber for collection. While stabilizing the sedimentation, it prevents the sedimentation from flowing out along the supernatant, and better sedimentation treatment of sewage.

Description

technical field [0001] The invention belongs to the field of sewage ecological treatment, and in particular relates to urban sewage treatment equipment. Background technique [0002] Sewage is water that does not meet hygienic standards due to pollution, and domestic sewage is the wastewater discharged from people's daily life. Because domestic sewage contains more germs or emits foul smell, if it is not treated, it will pollute the water. , land and other ecological environments, so when urban sewage is discharged, it is necessary to treat the sewage to make it meet the discharge standards and better protect the ecological environment, but the existing technologies have the following deficiencies: [0003] Since the sewage pipes are often large, and in the urban domestic sewage, there are often residues or impurities that can be washed out. After entering the sewage treatment equipment, sedimentation treatment is often carried out, and the sedimentation tank has always main...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a kind of urban sewage treatment equipment to solve the problem that in the prior art, because the sewage pipes are often large, and the domestic sewage in the city often contains some slag that can be washed out. After entering the sewage treatment equipment, the residues or impurities of things will often undergo sedimentation treatment, and the sedimentation tank has always maintained a high water level, which is filtered out by the supernatant, and if the sewage inlet pipe is at the lower end, it is easy to wash away the sedimented debris. If it is at the upper end, it is easy to flush the unsettled sewage directly out of the sedimentation tank
