Problems solved by technology

[0003] At present, biological contact oxidation tanks are often used in the process of domestic sewage treatment. By setting fillers in the oxidation tanks, they are used as biofilm carriers. After being aerated with oxygen, the waste water to be treated flows through the fillers at a certain flow rate. Biofilm contact, biofilm and suspended activated sludge work together to purify wastewater. However, the existing biological contact oxidation tank still has certain deficiencies. During use, the residence time of oxygen in the treatment tank It is short and cannot fully contact with the biofilm in the filler, resulting in low biofilm activity. Therefore, it is urgent to design a biological contact oxidation tank for domestic sewage treatment to solve the above problems

Embodiment 1

[0030] refer to Figure 1-4 , a biological contact oxidation tank for domestic sewage treatment, comprising a treatment tank 1, the inner wall of the treatment tank 1 is fixedly connected with a partition 11, and a filter mechanism is arranged between the partition 11 and the treatment tank 1, and the bottom inner wall of the treatment tank 1 Equidistantly distributed stuffing cylinders 2 are provided, and the adjacent stuffing cylinders 2 are fixedly connected by connecting pipes 4. The inside of the treatment tank 1 is provided with a backwater chamber 5, and one stuffing cylinder 2 is connected to the backwater chamber 5 through a fixed pipe 19. The inner wall of the bottom of the treatment tank 1 is provided with a return pipe 6, and one end of the return pipe 6 communicates with the return chamber 5, the inner wall of the bottom of the treatment tank 1 is provided with a water pump 9, and the water pump 9 passes through the water guide pipe 7 and the packing cylinder 2 Th...

Embodiment 2

[0038] refer to Figure 5 , a biological contact oxidation pond for domestic sewage treatment. Compared with Embodiment 1, this embodiment also includes a heating plate 30 arranged on one side of the outer wall of the partition 11 .

[0039] A temperature sensor 31 is provided on one side of the processing tank 1, and the temperature sensor 31 is connected to a controller through a signal line, and the signal input end of the controller is connected to the switch of the heating plate 30 through the signal line.

[0040] Working principle: when in use, the sewage in the treatment tank 1 can be heated through the heating plate 30, and the temperature of the sewage can be detected through the temperature sensor 31. When the appropriate temperature is reached, the heating plate 30 is prompted to stop working, so that the sewage can be maintained At an appropriate temperature, to ensure the activity of microorganisms in the stuffing cylinder 2, the use effect is better.

Abstract

The invention discloses a biological contact oxidation pond for domestic sewage treatment. The biological contact oxidation pond comprises a treatment pond, the inner wall of the treatment pond is fixedly connected with a partition plate, a filtering mechanism is arranged between the partition plate and the treatment pond, filler cylinders distributed at equal intervals are arranged on the inner wall of the bottom of the treatment pond, the adjacent filler cylinders are fixedly connected through a communicating pipe; a water return cavity is formed in the treatment tank, one filler cylinder iscommunicated with the water return cavity through a fixing pipe, a water return pipe is arranged on the inner wall of the bottom of the treatment tank, one end of the water return pipe is communicated with the water return cavity, and a water pump is arranged on the inner wall of the bottom of the treatment tank and communicated with the filler cylinder through a water guide pipe. According to the invention, the oxygen supply amounts of all parts in the packing cylinder can be kept consistent, and part of oxygen led out of the air holes can be remained in the fixed cover on the air guide pipe, so that the retention time of the oxygen in the packing cylinder is effectively prolonged, the oxygen can be in full contact with microorganisms, and the treatment effect is better.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a biological contact oxidation pond for domestic sewage treatment. Background technique [0002] Sewage treatment refers to the process of purifying sewage to meet the water quality requirements of being discharged into a certain water body or reused. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering In various fields, sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. [0003] At present, biological contact oxidation tanks are often used in the process of domestic sewage treatment. By setting fillers in the oxidation tanks, they are used as biofilm carriers. After being aerated with oxygen, the waste water to be treated flows through the fillers at a certain flow rate. Biofilm contact, biofilm and s...
