Problems solved by technology

[0005] The common points of the above several treatment processes are the combined treatment process under anaerobic (anoxic) and aerobic conditions. The existing units are relatively complicated, sludge or sewage reflux is required, there are many operating equipment, and the power consumption is large, which is not convenient for engineering. Management and other shortcomings

Embodiment Construction

[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0035] Such as figure 1 and image 3 In the shown air-lift internal circulation sewage treatment device, a partition 1 is set in the biochemical pool, and the biochemical pool is divided into two main functional areas, A area 2 and B area 3, and the area between the partition 1 and the pool wall is B area 3 is the non-aeration area, the area surrounded by the partition 1 is A area 2 is the aeration area, in order to ensure the smooth circulation of the mixed liquid, between the upper end of the partition 1 and the water surface, the lower end of the partition 1 and the bottom of the pool There is a certain space between them, and the partition plate 1 between the A zone 2 and the B zone 3 can avoid the short circuit of the water. In order to blow air into the pool, an aeration system...

Abstract

The present invention discloses one kind of airlift inner circulation sewage treating process and apparatus. The biochemical tank is provided with partition board or wall for separating the tank into one aeration area A with bottom aeration system for blasting air and one non-aeration area B. The area A is provided with the primary guide plate to alter water flow direction and realize water circulation between the area A and the area B; and the area B is provided with stuffing. The present invention has simple structure, low power consumption, increased sewage reflux ratio and raised pollutant eliminating effect.

Description

technical field [0001] The invention relates to a biochemical sewage treatment process and device, belonging to the technical field of sewage treatment in the environmental protection industry. Background technique [0002] Treatment process for removing difficult-to-degrade or high-concentration organic pollutants: In sewage treatment projects, in order to remove difficult-to-degrade or high-concentration organic pollutants, biochemical-based treatment processes mostly use anaerobic (anoxic) Combined biochemical process with aerobic biological treatment. [0003] Biological denitrification treatment process: Nitrification and denitrification treatment processes are generally used to remove total nitrogen. Biological nitrification refers to the process in which nitrifying bacteria oxidize ammonia nitrogen to nitrate nitrogen in an aerobic process; Under this condition, denitrifying bacteria reduce nitrate nitrogen to nitrogen gas to remove nitrogen from sewage. [0004] Bi...
