Abstract

The invention relates to an adjustable-water-pressure sewage treatment tank which comprises a tank body (9), wherein the tank body (9) is in a cuboid shape; the upper end is provided with a sewage inlet pipe (91), and the lower end is provided with a treated water outlet pipe (92); the inner cavity of the tank body (9) is sequentially divided into an upper treatment section (93), a middle treatment section (94) and a lower treatment section (95) from top to bottom; a first sewage treatment plant (931) is arranged in the upper treatment section (93); a second sewage treatment plant (941) is arranged in the middle treatment section (94); a third sewage treatment plant (951) is arranged in the lower treatment section (95); and a separation structure is respectively arranged between the upper treatment section (93) and middle treatment section (94), and between the middle treatment section (94) and lower treatment section (95).

Description

technical field [0001] The invention belongs to the field of sewage treatment, in particular to a sewage treatment tank with adjustable water pressure and a cleaning method thereof. Background technique [0002] Sewage treatment tank is a kind of sewage treatment equipment commonly used in the field of sewage treatment. Sewage treatment tanks are usually equipped with multiple treatment devices with different functions from top to bottom to perform multi-level treatment of sewage, such as physical filtration, chemical removal, sedimentation, etc. [0003] Sewage treatment tanks often need to be maintained and cleaned after being used for a certain period of time. However, during the cleaning process, especially during reverse cleaning, it is easy to cause cross-contamination of sewage treatment devices at different levels, thereby causing damage to the treatment equipment. Contents of the invention [0004] The object of the present invention is to provide a sewage treat...
