Problems solved by technology

However, the natural exchange function between the river and the soil is poor, and the water environment cannot be renewed. For a long time, the water quality of the river has deteriorated, and even blackened and smelly.
Traditional protection projects pay too much attention to economic interests, without comprehensive analysis and consideration of the natural evolution of the river and the service functions of the river ecosystem. A large number of concrete is used, which is easy to damage the vegetation on the bank slope and damage the nearby environmental zone. to adversely affect

Embodiment 1

[0032] see Figure 1-2 As shown, the present invention provides a river sewage treatment device, including a device body 1 arranged at the river sewage outlet 10, the device body 1 is provided with an interception area 11, a sewage treatment area 12 and a discharge area 13, and the interception area 11 is arranged on the device The front end of the body 1, and the intercepting area 11 is connected with the river sewage outlet 10, the sewage treatment area 12 is arranged in the middle of the device body 1, and the sewage treatment area 12 is provided with a sewage treatment device that uses microorganisms to treat sewage. After the outflowing sewage enters the device body 1 through the interception area 11, it is treated by the sewage treatment device to meet the discharge standard and then discharged from the discharge area 13. The discharge area 13 is set at the rear end of the device body 1, and the discharge area 13 is far away from the river sewage outlet One end of 10 is ...

Embodiment 2

[0037] see Figure 1-2 As shown, this embodiment is optimized and limited on the basis of the above-mentioned embodiment 1.

[0038] The sewage treatment device includes a microbial bed and an aerator 3 for oxygenation. The aerator 3 is arranged on the surface of the sewage treatment area 12 and floats on the water surface by the buoyancy of water. In this embodiment, according to the width of the river, the depth of water and the amount of water, an appropriate number can be set, more than one aerator 3, so that the oxygen content of the water body in the sewage treatment area 12 is increased, and microbial bacteria are thrown into the sewage treatment area 12. After the agent (symbiotic bacteria), the aerator 3 can provide enough oxygen to activate and amplify the added microbial agent, gradually form a microbial bed, and dilute and degrade the pollutants in the sewage treatment area 12 through microorganisms At the same time, it is also possible to nitrify the bottom sludg...

Embodiment 3

[0040] see Figure 1-2 As shown, this embodiment is optimized and limited on the basis of the above-mentioned embodiment 1.

[0041] There are two automatic valves 2, and the two automatic valves 2 are arranged side by side on both sides of the discharge area 13 away from the river sewage outlet 10, so as to facilitate the control of the discharge of the water flow, and the valve can be automatically closed after the set water flow is discharged; The water flowing through the discharge area 13 can be directly discharged through the automatic valve 2 and enter the downstream stage after being tested by the water quality testing device to reach the corresponding standard. At this time, the treated water itself has self-purification ability (carrying the formed microbial bed) , It can also purify the slightly polluted water downstream. Add the microbial agent to the sewage treatment area 12 at least once a month.

Abstract

The invention relates to the technical field of sewage treatment, and discloses a riverway sewage treatment device and a treatment method thereof. The riverway sewage treatment device is provided withan interception area, a sewage treatment area and a discharge area. Garbage floating in the sewage is blocked through the interception area, and meanwhile, the sewage and the garbage flowing out of the sewage draining exit of the river channel can be prevented from directly flowing into the river; microorganisms are adopted in the sewage treatment area to carry out ecological restoration on a polluted water body to form a benign water environment, so that the ecological balance of the water body is achieved, pollutants in the water body are biologically decomposed and purified, the surrounding ecological environment is not damaged, and the forward balance of the water body is improved; and the water flow with the water quality reaching the standard is controlled to be discharged into theriver through an automatic valve of the discharge area.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a river sewage treatment device and a treatment method thereof. Background technique [0002] River water pollution is a major problem facing river management at present, and the sources of water pollution are mainly industrial, agricultural and domestic sewage. At present, the acceleration of urbanization is the current trend of social and economic development. With the increase in the number of cities and the increase in population, a large amount of domestic wastewater and garbage are constantly pouring into the river, resulting in worsening water quality in the river. Imperfect, lagging river management, river pollution intensified. [0003] Most of the previous river channel management projects considered the function of flood control. At the same time, due to the limitations of construction conditions and technology, they were more inclined to prevent ...
