Description

Technical Field

[0001] The utility model relates to the technical field of carbon neutrality, and in particular to a carbon neutrality sewage treatment device. Background Art

[0002] During the sewage purification process, the carbon dioxide produced by common microorganisms during their respiration will be discharged into the atmosphere, and the pollution will be transferred from the water to the atmosphere, and carbon neutrality has not been achieved. Methanogens can decompose organic matter in certain domestic and industrial wastewaters through fermentation, thereby purifying the sewage. In addition, during the sewage purification process, the metabolic product of methanogens is methane. Using methanogens to treat sewage can achieve carbon neutrality. However, since methanogens grow and reproduce very slowly, in order to effectively utilize the purification ability of methanogens, it is necessary to increase the effective contact between methanogens and sewage and carbon sources. In the prior art, methanogens are easily accumulated in sewage. In addition, carbon sources are placed at fixed points, resulting in uneven distribution in sewage. These all result in a small effective contact area between methanogens and sewage and carbon sources, affecting the purification efficiency. Utility Model Content

[0015] The present invention is described in detail below in conjunction with the various embodiments shown in the accompanying drawings, but it should be noted that these embodiments are not limitations of the present invention, and any equivalent transformations or substitutions in functions, methods, or structures made by ordinary technicians in the field based on these embodiments are all within the scope of protection of the present invention.

[0016] like Figure 1-4 A carbon neutral wastewater treatment device is shown, comprising an anoxic tank 1 and a tank cover 14 sealed and connected to the anoxic tank 1. The bottom of the anoxic tank 1 is also provided with a support leg 15. The anoxic tank 1 is provided with an inlet pipe 11 and a drain pipe 12, and the inlet pipe 11, the drain pipe 12 and the anoxic tank 1 are an integrated structure. The tank cover 14 is provided with an exhaust pipe 13, and the exhaust pipe 13 and the tank cover 14 are an integrated structure.

[0017] The anoxic tank 1 is provided with a plurality of connecting ropes 51, and the connecting ropes 51 are connected with a plurality of suspended ball fillers 5. Microorganisms can attach to the suspended ball fillers 5, so that the microorganisms can be evenly distributed in the sewage, increasing the contact area with the sewage and the carbon source, and improving the sewage purification efficiency.

[0018] The anoxic tank 1 is provided with an annular platform 4, and a plurality of through holes 40 are evenly spaced on the annular platform 4. One end of the connecting rope 51 is connected to the annular platform 4. Specifically, one end of the connecting rope 51 is connected to a hook 52, and the hook 52 is hooked in the through hole 40 to facilitate the operation of taking and placing the suspended ball filler 5 in the sewage. The other end of the connecting rope 51 is connected to a counterweight 53, and the counterweight 53 is located at the bottom of the sewage to keep the connecting rope 51 in a vertical state.

[0019] The anoxic tank 1 is provided with a carbon source adding mechanism 2, and the carbon source adding mechanism 2 includes a straight tube portion 21 and a hollow spherical crown portion 22 which are connected, and a plurality of adding ports 230 are evenly distributed around the bottom 23 of the hollow spherical crown portion 22. The straight tube portion 21 is provided with a first cavity 210, and the hollow spherical crown portion 22 is provided with a second cavity 220, and the second cavity 220 is in the shape of a hollow spherical crown, and the first cavity 210, the second cavity 220 and the adding port 230 are connected.

[0020] The straight tube portion 21 and the tank cover 14 are an integrated structure, and the hollow spherical crown portion 22 is located inside the anoxic tank 1. The specific length of the straight tube portion 21 can be designed according to the form of the carbon source. For example, if the carbon source is a gas, the straight tube portion 21 can be designed to be longer so that the hollow spherical crown portion 22 is deeply immersed in the sewage; if the carbon source is a liquid, the straight tube portion 21 can be designed to be shorter so that the hollow spherical crown portion 22 is located above the sewage surface.

[0021] The carbon source enters the second cavity 220 through the first cavity 210. Since the second cavity 220 is in the shape of a hollow spherical crown, the carbon source will evenly flow into the bottom 23 of the hollow spherical crown 22, and then be added to the sewage from the addition port 230. The use of multiple addition ports 230 arranged in a ring shape can make the carbon source quickly and evenly distributed in the sewage, and react with the microorganisms on the suspended ball filler 5 to achieve carbon neutralization treatment of the sewage.

[0022] The anoxic tank 1 is provided with a stirring mechanism. The stirring mechanism is located at the bottom of the anoxic tank 1, and the stirring mechanism includes a motor 31 and a stirring blade 32 driven by the motor 31. The carbon source can be quickly and evenly mixed in the sewage by regular stirring of the stirring mechanism to promote the growth and reproduction of microorganisms, so that the microorganisms, sewage and carbon source are effectively contacted. Stirring can also prevent sludge from being deposited on the bottom of the tank and maintain the stability of the nitrification reaction.
