Abstract

The utility model discloses a sewage treatment device used for urban construction, comprising a cylindrical fermentation tank with one end provided with a water inlet pipe and the other end provided with a water outlet pipe. The upper part of the cylindrical fermentation tank is provided with a gas accumulating cover, on which a methane educing pipe is arranged; a baffle plate is arranged in the cylindrical fermentation tank. When in use, sewage is fed in the cylindrical fermentation tank through a feed port and is baffled by the baffle plate, and the flow state of fermented fluid is changed to ensure full fermentation so as to generate methane; and then fermented fluid enters into another part of the cylindrical fermentation tank while the fermented methane is gathered in the gas accumulating cover and sent to users through the methane educing pipe on the gas accumulating cover; the treated liquid is discharged through the water outlet pipe to a hydraulic room. The sewage treatment device used for urban construction has simple structure, and is explosion-proof with full fermentation.

Description

Sewage treatment device for urban construction

technical field

The utility model relates to an environmental protection device, in particular to a device capable of treating sewage and generating biogas.

Background technique

At present, in China's urban construction, the sewage treatment method is relatively simple. Most of the sewage is directly discharged into the septic tank of the traditional brick-concrete structure and discharged along the sewer without treatment. This not only pollutes the environment, but also affects people's health. And in recent years, especially in summer, biogas explosions in septic tanks and sewers have occurred from time to time, seriously affecting the lives and property safety of the people. Utilization, when the biogas reaches a certain amount, explosion accidents are easy to occur, and the biogas explosion is directly related to the structure of the traditional brick-concrete septic tank. The traditional brick-concrete septic tank has a single structure, including square The septic tank body and the sealing cover above are poorly airtight if the brick-concrete type is used, and it is easy to leak and pollute the groundwater source. When there is a lot of methane accumulation, it is easy to overflow from the pipe mouth, and it will explode when it encounters an open flame. , and the construction of the traditional brick-concrete septic tank body structure is troublesome, uneconomical, and not environmentally friendly.

Utility model content

The purpose of the utility model is to provide a sewage treatment device for urban construction which has a simple structure and prevents methane explosion.

In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: including the water inlet pipe, the water outlet pipe, and the fermentation tank body, the water inlet pipe is at one end of the fermentation tank body, and the water outlet pipe is at the other end of the fermentation tank body. There is a gas-gathering hood, and a biogas outlet pipe is arranged on the gas-gathering hood.

The fermenter body is long columnar.

A baffle is arranged radially inside the fermenter body.

The fermenter body is made of fiberglass.

When in use, the sewage treatment device for urban construction is buried obliquely by laying a sand cushion, and the sewage flows from the water inlet pipe to the fermentation tank body. The biogas produced by fermentation will first gather in the gas gathering hood when it diffuses, and it is not easy to overflow from the pipe mouth. , and then transported to the user through the biogas outlet pipe installed on the gas gathering hood, which is convenient for the user and prevents the explosion of excessive accumulation of biogas, and the treated liquid is discharged from the discharge port to the water pressure room; fermentation The tank body adopts a long cylindrical shape to facilitate processing and manufacturing. Due to the inclined embedding, the sewage flows downward by its own weight and is deflected by the baffle plate, which changes the flow state of the fermentation liquid and can be fully fermented better. The gas gathering hood can also be used It is used as a channel for entering and exiting the tank when cleaning the tank regularly; the fermenting tank is made of glass fiber reinforced plastic to reduce weight, prevent leakage and cause environmental pollution; the whole device can save space above the ground after being buried underground, and can be greened on the ground.

Description of drawings

Fig. 1 is a structural schematic diagram of a sewage treatment device for urban construction.

Detailed ways

The sewage treatment device for urban construction shown in Fig. 1 comprises a long cylindrical fermentation tank body 2, an inlet pipe 1 is provided at one end of the fermentation tank body 2, an outlet pipe 3 is provided at the other end, and a water outlet pipe 3 is provided at the fermentation tank body 2 top. The gas-gathering hood 5 is equipped with a biogas outlet pipe 4 above the gas-gathering hood 5, and a baffle 6 is arranged radially inside the fermenter body 2. The whole device adopts a buried type, and is placed obliquely by laying a sand cushion 7.

When in use, the sewage enters the fermentation tank body 2 from the water inlet pipe 1, passes through the baffle plate 6, and enters the other part of the fermentation tank body 2, and the fermented biogas gathers in the gas gathering hood 5, and then passes through the biogas outlet pipe 4 Transported to the user, the treated liquid is discharged from the water outlet pipe 3 to the water pressure room.
