Problems solved by technology

[0003] With the increase of sewage, the number of sewage plants has also increased; as the name suggests, sewage plants are facilities for sewage treatment, and the most common problem in sewage plants is the lack of carbon sources in sewage treatment, and insufficient carbon sources will directly reduce the waste water plants Nitrogen effect, the general solution is to artificially add organic carbon sources or add chemicals, but this method greatly increases the treatment cost of the sewage plant, and does not meet the sustainable development strategy

Embodiment 1

[0028] refer to Figure 1-3 , a tail water deep denitrification device based on methane oxidation, comprising a sludge fermentation tank 3, the outer wall of the top of the sludge fermentation tank 3 is fixedly connected with an air inlet pipe 4, and the outer wall of one side of the sludge fermentation tank 3 is provided with a tail water Inlet 2, the outer wall of the intake pipe 4 is provided with a one-way valve 5, and the outer wall of one end of the intake pipe 4 is fixedly connected with the gas storage tank 6, and the side of the sludge fermentation tank 3 is provided with an aeration tank 12, and the outer wall of the aeration tank 12 is A sedimentation tank 10 is fixedly connected, and a denitrification cylinder 8 is arranged on one side of the sedimentation tank 10. The sludge fermentation tank 3 and the aeration tank 12, the sedimentation tank 10 and the denitrification cylinder 8 are all connected to each other through a suction pump. The side outer wall is provid...

Embodiment 2

[0037] refer to Figure 4 , a deep denitrification device for tail water of a sewage plant based on methane oxidation. Compared with Example 1, the inner wall of one side of the denitrification cylinder 8 is fixedly connected with an oxygen film 18, and one side of the denitrification cylinder 8 is provided with an oxygen storage tank 19 , the oxygen storage tank 19 is connected with the oxygen membrane 18 through the trachea to provide a better growth and reproduction environment for the methane oxidizing bacteria in the denitrification cylinder 8, thereby improving the denitrification efficiency.

[0038] Working principle: Compared with Example 1, the inner wall of one side of the denitrification cylinder 8 is fixedly connected with an oxygen film 18, and one side of the denitrification cylinder 8 is provided with an oxygen storage tank 19, and the oxygen storage tank 19 is connected to the oxygen film 18 through a trachea. The oxygen storage tank 19 transports oxygen throu...

Abstract

The invention discloses a sewage plant tail water deep denitrification device based on methane oxidation. The device comprises a sludge fermentation box, a gas inlet pipe is fixedly connected to the outer wall of the top of the sludge fermentation box, and a tail water inlet is formed in the outer wall of one side of the sludge fermentation box. A one-way valve is arranged on the outer wall of thegas inlet pipe, a gas storage tank is fixedly connected to the outer wall of one end of the gas inlet pipe, an aeration tank is arranged on one side of the sludge fermentation tank, a sedimentation tank is fixedly connected to the outer wall of one side of the aeration tank, a denitrification cylinder is arranged on one side of the sedimentation tank, and the sludge fermentation tank is connectedwith the aeration tank, the sedimentation tank and a denitrification cylinder through extraction pumps; a gas feeding pipe is arranged on the outer wall of one side of the gas storage tank, and the outer wall of one end of the gas feeding pipe is fixedly connected to the top outer wall of the denitrification cylinder. By arranging the sludge fermentation tank, the gas storage tank and the aeration tank, tail water and sludge can be separated, the sludge generates methane in the sludge fermentation tank, a nitrification carbon source is provided for the denitrification cylinder, the cost of asewage treatment plant is reduced, and emission of greenhouse gas is reduced.

Description

technical field [0001] The invention relates to the technical field of tail water treatment, in particular to a deep denitrification device for tail water of a sewage plant based on methane oxidation. Background technique [0002] With the rapid development of modern society and the rapid advancement of urbanization, the discharge of sewage is increasing day by day; the main pollutants of sewage include pathogen pollutants, oxygen-consuming pollutants, plant nutrients and toxic pollutants, etc. If these are not removed, Direct discharge will cause serious pollution to the ecology. [0003] With the increase of sewage, the number of sewage plants has also increased; as the name suggests, sewage plants are facilities for sewage treatment, and the most common problem in sewage plants is the lack of carbon sources in sewage treatment, and insufficient carbon sources will directly reduce the waste water plants Nitrogen effect, the general solution is to artificially add organic ...
