Deep well aeration device and sewage treatment process thereof

Abstract

The invention belongs to the technical field of sewage treatment, and particularly relates to a deep well aeration device and a sewage treatment process thereof. The deep well aeration device comprises a canal communicated with a sewer, and a grit chamber, a deep well, a degassing tank and a secondary sedimentation tank which are sequentially arranged on the side, away from the sewer, of the canal; a thick grid and a thin grid are arranged in the canal; a float bowl is arranged between the thick grid and the thin grid; a pair of sliding grooves are formed in the side face of the canal on the side, away from the float bowl, of the thin grid, rotating shafts are slidably connected into the sliding grooves, and a set of cleaning rods are evenly distributed on the periphery of a roller fixedlyconnected to the middle of each rotating shaft and used for being inserted into the fine grid to clean white garbage during rotation; one end of the pull rope is fixedly connected with the float bowl, and the other end of the pull rope winds around a guide wheel at the bottom of the canal and then anticlockwise winds around the periphery of the roller; a storage tank used for recycling white garbage is arranged on the side, away from the thin grid, of the top of the sliding groove; according to the invention, the float bowls drive the rollers to rotate to clean the thin grids, and the filtering efficiency of the thin grids is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a deep well aeration device and a sewage treatment process thereof. Background technique [0002] Deep well aeration (Deep Shaft Process), also known as "ultra-deep water aeration", "ultra-deep aeration", is a new type of wastewater treatment process. The technological process is: fine grid - grit chamber - deep well aeration - degassing tank - secondary sedimentation tank - drainage. [0003] Because the deep well aeration process has the advantages of less land occupation, environmental friendliness, simple operation and maintenance, and low operating costs in the process of sewage treatment, it is greatly favored in areas where the city scale is expanding rapidly and the land area of ​​sewage treatment plants is restricted. [0004] There are also some technical solutions about deep well aeration in the prior art. For example, a Chinese patent with application number...

AI Technical Summary

Problems solved by technology

[0005] In order to make up for the deficiencies of the existing technology, all forms of fine grids in the existing deep well aeration device are easily blocked, and follow-up manual cleaning is required. The workload is heavy, the operation is not convenient, and sometimes even affects the sewage treatment. The problem of efficiency, the deep well aeration device and its sewage treatment process that the present invention proposes
