Embodiment 1

[0031] Please refer to Figures 1 to 4 , the present embodiment provides an ecological and biochemical combination unit device, which is an ecological and biochemical combination unit device for aeration, and is set in the ecological biochemical pool of the vertical A / A / O process, and the ecological biochemical pool is provided with There is a combined ecological zone, and a sludge stabilization zone I is provided at the bottom of the combined ecological zone. To be connected with the intake pipe (not shown) in the sewage treatment system, the upper opening of the three-way pipe 9 is connected with the air pipe 8, and the two lower openings of the three-way pipe 9 are respectively connected with one of the air pipes. The aeration tube 3 is connected, the combined filler 2 is arranged on the carrier bracket 1, the aeration tube 3 is arranged horizontally, and the middle position of the aeration tube 3 communicates with the three-way tube 9, so The aeration tube 3 is used for a...

Embodiment 2

[0036] Please refer to figure 1 , Figure 5 and Image 6 , the present embodiment also provides an ecological and biochemical combination unit device, which is an ecological and biochemical combination unit device for backflow, and is located in the ecological and biochemical pool of the sewage treatment system, including a carrier bracket 1, a combined filler 2, and an air pipe 8 , a three-way pipe 9 and a vertical return module 4, the upper end of the air pipe is used to connect with the intake pipe (not shown) in the sewage treatment system, and the upper port of the three-way pipe 9 is connected to the air pipe 8, the two lower ports of the three-way pipe 9 are respectively connected to one of the vertical return modules 4, and the combined filler 2 is arranged on the carrier bracket 1.

[0037] Please refer to Figure 8 , the vertical return module 4 at least includes a vertically arranged return air pipe 10 and a sleeve 11 sleeved outside the return air pipe, the retu...

Embodiment 3

[0042] This embodiment provides an ecological biochemical pool, wherein a combined ecological area is provided, and a sludge stabilization area I is provided at the bottom of the combined ecological area, and several use as described in Example 1 are arranged in the combined ecological area. In the ecological and biochemical combination unit device for aeration and the ecological and biochemical combination unit device for reflux as described in embodiment 2, the adjacent two ecological and biochemical combination unit devices are arranged at intervals,

[0043] Therefore, through the arrangement of several ecological and biochemical combination unit devices used for aeration, the change of dissolved oxygen content in the vertical direction is realized, and then the combined ecological zone is divided into sludge stabilization zone I, anaerobic zone I and anaerobic zone from bottom to top in the vertical direction. zone II, anoxic zone III and aerobic zone IV;

[0044] Further...

Abstract

The invention provides two ecological and biochemical combined unit device and an ecological and biochemical pool. A combined ecological zone is arranged in the ecological and biochemical pool, a sludge stability zone is arranged at the bottom of the combined ecological zone, a plurality of ecological and biochemical combined unit devices for aeration and a plurality of ecological and biochemical combined unit devices for backflow are arranged in the combined ecological zone, and every two adjacent ecological and biochemical combined unit devices are arranged at an interval, so that the content variation of vertically dissolved oxygen is realized through the arrangement of the ecological and biochemical combined unit devices for aeration, and further, the combined ecological zone is sequentially divided into the sludge stability zone, an anaerobic zone, an anoxic zone and an aerobic zone from bottom to top in the vertical direction. Backflow of a mixed liquor between the anoxic zone and the aerobic zone is realized through vertical backflow modules in the ecological and biochemical combined unit devices for backflow.

Description

technical field [0001] The invention relates to the field of water pollution control, in particular to an ecological biochemical combination unit device and an ecological biochemical pool. Background technique [0002] With the acceleration of urbanization, the aggravation of water pollution and the continuous increase in the control of sewage discharge and standards in China, various new sewage treatment processes are emerging, and the treatment cost is low and the treatment effect is still biochemical treatment technology. [0003] With the improvement of drainage standards, new requirements are put forward for biochemical systems. The treatment efficiency of COD, ammonia nitrogen, and phosphorus must be improved. At the same time, the biochemical aeration system and filler system of the previous biochemical treatment system are fixed in the tank. If maintenance is required, the biochemical treatment system needs to be emptied, which affects the The treatment capacity of ...
