Abstract

A sewage treatment device capable of detecting failure of an air diffuser pipe, equipped with a sewage treatment tank for treating sewage, and a system for blowing air supplied from a blower into the sewage in the sewage treatment tank or The sewage treatment device of multiple systems of air diffusion pipes is further equipped with one or more systems of pressure sensors for detecting abnormal pressure on the inlet side of the one or more systems of air diffusion pipes.

Description

technical field [0001] The present invention relates to a sewage treatment device, and more specifically relates to a sewage treatment device equipped with an air diffusion pipe. Background technique [0002] Air diffuser pipes have been used for various purposes in conventional sewage treatment plants. For example, in the integrated treatment purification tank described in JP-A-10-192869, a total of five air-air diffuser pipes of No. 1 to No. 5 are used. The first air diffusion pipe is used in the contact blowing tank to keep the contact blowing tank in an aerobic state, and decompose the water through aerobic microorganisms, and decompose ammonia nitrogen into nitric acid and nitrous acid through the action of nitric acid bacteria and nitrous bacteria Sexual nitrogen. The second air diffusion pipe is also used in the contact blowing tank to peel off the biofilm attached to the contact material, proliferating and gradually thickening. The 3rd air diffuser pipe is arrange...
