Problems solved by technology

[0003] Traditional sewage treatment tanks are all closed, but there are still gaps in the closure, and liquid-gas exchange is inevitable
In order to deal with the gas, the method of exhaust gas absorption is adopted. At this time, the air flow is larger, the volatilization is larger, and the gas concentration is high and there is a danger of explosion.

Embodiment 1

[0029] Such as Figure 1-2 As shown, a sewage treatment equipment with a floating roof includes a sewage tank 1 and a floating roof that can move up and down with the liquid surface; the sewage tank 1 includes an aeration tank, an anaerobic tank or a sewage collection tank, and the floating roof is one or Multiple, when there are multiple floating roofs, they are in contact with each other but not connected, there are gaps between them, and the floating roofs are flat roofs 2 .

[0030] The above-mentioned flat top 2 is a board or a hollow plastic board with a density of 0.8-0.9.

Embodiment 2

[0032] Such as Figure 3-5 As shown, a sewage treatment equipment with a floating roof includes a sewage tank 1 and a floating roof that can move up and down with the liquid surface; the sewage tank 1 is an anaerobic tank, and there are one or more floating roofs. At the same time, they are in contact with each other but not connected, there is a gap between them, and the floating roof is a raised roof 3.

[0033] The above raised top 3 is high in the middle, low at the edge, and slopes smoothly downward from the middle to the edge. The highest point in the middle of the raised top 3 is provided with an air outlet 9, and the air outlet 9 is connected to the air outlet pipe 4, and the air outlet pipe 4 is connected to the connecting pipe 5 , the diameter of the connecting pipe 5 is larger than the outlet pipe 4, and the end of the connecting pipe 5 is fixedly connected with the floating roof 2, and the end of the outlet pipe 4 is provided with a jacking valve, which can be driv...

Abstract

The invention provides sewage treatment equipment with a floating roof(s) and a methane gas recovery method. The sewage treatment equipment comprises a sewage pool and one or more floating roofs capable of moving up and down along a liquid level, wherein the sewage pool comprises an aeration tank, an anaerobic pool or a sewage collecting tank; in case of more floating roofs, the floating roofs arein contact with one another but not connected, gaps are formed among the floating roofs, and the floating roofs are flat roofs or convex roofs. The floating roofs are correspondingly changed along with ascent and descent of the liquid level, the collected gases can be safely guided out due to the arrangement of a jacking valve, organic waste gases do not directly evaporate, and the sewage treatment equipment is safe and convenient.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment devices, and in particular relates to sewage treatment equipment with a floating roof and a method for recovering methane gas. Background technique [0002] During the sewage treatment process, the organic matter in the sewage is decomposed, metabolized, and digested by anaerobic bacteria, which greatly reduces the organic matter content in the sewage and produces biogas at the same time. These gases need to be exported through pipelines. [0003] Traditional sewage treatment tanks are closed, but there are still gaps in the closure, and liquid-gas exchange is inevitable. In order to deal with the gas, the method of tail gas absorption is adopted. At this time, the air flow is larger, the volatilization amount is larger, and the gas concentration is high and there is a risk of explosion. Contents of the invention [0004] In view of this, the present invention aims to propose a sewage...
