Problems solved by technology

The ratio of the hydraulic retention time of the anaerobic section, the anoxic section and the aerobic section of the traditional A / A / O process, that is, the volume ratio of each reaction section, is generally 1:1:3~4, and the relative volume is fixed. Poor adjustability. It is difficult to adjust the hydraulic retention time and treatment load of each reaction section of industrial wastewater with special water quality. It cannot adapt to some industrial wastewater with high salinity, high COD, high concentration of refractory organic matter, high nitrogen, and high phosphorus. Development and application of similar biochemical reactor
[0003] Chinese patent CN201110157920.0 discloses "an adjustable biochemical pool and its adjustable A / A / O process for water treatment". Although the process is changeable, it fails to fundamentally change the anaerobic section and the anoxic section respectively. and the actual volume size of the aerobic section and the relative hydraulic retention time ratio
Chinese patent CN200510132777.4 "five-factor adjustable sewage treatment device", the volume ratio of anaerobic pool, anoxic pool and aerobic pool can be adjusted, but the anaerobic pool, anoxic pool and aerobic pool need to be arranged in sequence, and It is connected into a large rectangular pool and adjusted by moving partition walls. The layout of several reaction sections is single, difficult to adjust, and the application range is limited.
Chinese patent CN103755024A discloses "a rotary adjustable anaerobic-anoxic-aerobic biochemical reactor". The main part of the segment (outer corridor) cannot be adjusted

Embodiment 1

[0040] Such as figure 1 and figure 2 As shown, a biochemical reactor for wastewater treatment with adjustable rotation angle, the reactor is in the form of a circular corridor, and a continuous water passage corridor of equal width and height is provided, which is allocated as an anaerobic section 3. Oxygen section 5 and aerobic section 7, wherein along the direction of waste water flow, 2 moving partitions 4 are set on the starting corridor, slide rails 21 are set on the wall of the annular corridor, and a transmission device 20 is arranged at the annular center of the biochemical reactor. The rotary arm 17 is rotated, and the rotary arm 17 is connected with the movable partition 4 on the slide rail 21 , and the distribution and adjustment of the volume of each segment is realized by moving the partition 4 . The lower or upper part of the movable partition 4 is provided with a water passing hole 22 .

Embodiment 2

[0046] The reactor provided by the present invention is used to treat general industrial wastewater. The design and layout of the reactor passageway and the separation mode of each biochemical reaction section, the operation control mode and parameters of the reactor and the aeration device are the same as in Example 1. . The difference from Example 1 is that different distribution volume ratios of anaerobic section, anoxic section and aerobic section are adopted for different treatment objects.

[0047]For the treatment of refractory industrial wastewater, the water quality indicators of industrial wastewater before treatment: COD is 1000-3000mg / L, ammonia nitrogen is about 30mg / L, and total phosphorus is about 5mg / L. Using the above-mentioned rotary adjustable anaerobic -The anoxic-aerobic biochemical reactor needs to prolong the relative hydraulic retention time of the anaerobic section and strengthen the effect of biochemical treatment in the anaerobic section. 3:2:7 or 4...

Embodiment 3

[0049] The reactor provided by the present invention is used to treat high-phosphorus wastewater. The design and layout of the reactor passageway and the separation mode of each biochemical reaction section, the operation control mode and parameters of the reactor and aeration device are the same as in Example 1. . The difference from Example 1 is that different volume ratios of anaerobic section, anoxic section and aerobic section are adopted for different treatment objects.

[0050] For the treatment of high-phosphorus wastewater, the water quality indicators of industrial wastewater before treatment: COD (chemical oxygen demand) is 400-1000mg / L, ammonia nitrogen is about 10mg / L, and total phosphorus is about 20mg / L. Using the above-mentioned rotary type can Adjusting the anaerobic-anoxic-aerobic biochemical reactor requires phosphorus removal, prolonging the relative hydraulic retention time of the anaerobic section and the aerobic section to facilitate anaerobic phosphorus...

Abstract

The invention discloses a corner adjustable type wastewater treatment biochemical reactor which is of annular gallery shape and comprises an anaerobic section (3), an anoxic section (5) and an aerobiotic section (7), wherein the anaerobic section (3) is connected with a water inlet pipe (1); the aerobiotic section (7) is connected with a water outlet pipe (8); a moveable separating plate (4) is arranged on the annular gallery; a slide rail (21) is arranged on an annular gallery wall; the moveable separating plate (4) is located on the slide rail (21); a driving device (20) is arranged at the center of the annular gallery; the moveable separating plate (4) is connected with the driving device (20) through a rotating arm (17); a water hole (22) is formed in the moveable separating plate (4). The corner adjustable type wastewater treatment biochemical reactor is reasonable in structure design; the relative staying time of each section can be flexibly adjusted according to the quality condition of the to-be-treated water; the microbial population is relative independent; the corresponding biochemical reaction environment is more stable; when different wastewater is treated, the efficient biochemical treatment can be kept; a settling pond is arranged at the center, so that the purifying effect is more excellent.

Description

technical field [0001] The invention relates to a wastewater biological treatment device, in particular to a biochemical reactor for wastewater treatment with adjustable rotation angle. Background technique [0002] The traditional A / A / O process is a typical urban sewage treatment process, which can solve the problems of organic matter removal, nitrogen and phosphorus removal in sewage to a certain extent. The ratio of the hydraulic retention time of the anaerobic section, the anoxic section and the aerobic section of the traditional A / A / O process, that is, the ratio of the volumes of each reaction section, is generally 1:1:3~4, and the relative volume is fixed. Poor adjustability. It is difficult to adjust the hydraulic retention time and treatment load of each reaction section of industrial wastewater with special water quality. It cannot adapt to some industrial wastewater with high salinity, high COD, high concentration of refractory organic matter, high nitrogen, and hi...
