[0021] In view of the lack of oxygen in the current municipal sewage pipeline during the transportation process, aerobic microorganisms cannot grow well in the pipeline, and the pipeline only plays the role of transporting sewage, wasting the role of sewage treatment inside it The object of the present invention is to provide an inspection well that relies on the flow of water body to automatically replenish oxygen to the downstream sewage pipeline. A hydraulic agitation device is installed in the inspection well to stir the water flow to drive the external air to quickly supplement into the downstream pipeline, thereby improving The activity of aerobic microorganisms in the downstream pipeline enables it to decompose and absorb organic pollutants in the sewage, obtain the effect of reducing the content of pollutants in the water, and reduce the treatment load of the sewage treatment plant to help reduce the treatment of the sewage treatment plant cost

Embodiment Construction
[0034] The applicant's design idea is to rely on the good ventilation of the inspection well and the outside world, and place a water flow stirring device at the inspection well. , 4 sources, place a water flow stirring device (ie pumping water truck) in the inspection well, rely on the impact force of the upstream water flow on it as the energy source, lift the sewage in the pipeline out of the water surface, and rely on the cheap spray to make it in the air Oxygen dissolves in the sewage, and the pumping water truck has a certain disturbing effect on the water flow at the inspection well, making the water flow in an unstable state and increasing its chance of contact with the air.
[0035] The pumping water truck is fixed in the inspection well by the water truck bracket on the wall. The height of the pumping water truck depends on the vertical distance between the outlet of the upstream sewage branch pipe and the outlet of the upstream sewage branch pipe. The overall size of...

The invention discloses an inspection well for automatically supplementing oxygen to a downstream sewage pipeline by water flow. The inspection well comprises an inspection well body, an upstream branch sewage pipeline is arranged on one side of the inner wall of the inspection well body, a main sewage pipeline is arranged at the bottom of the inspection well body, water in the upstream branch sewage pipeline flows downwards into the main sewage pipeline, and a water-raising waterwheel is mounted at the bottom of the inspection well body, positioned on the water surface of the main sewage pipeline and fixed onto walls on two sides of the inspection well body by fixing supports. The inspection well is simple in structure and convenient to mount, detach and maintain. The used water-raising waterwheel has a certain buoyancy, the submerged depth of the water-raising waterwheel in the inspection well body can be properly adjusted according to the water levels of the pipelines, the water-raising waterwheel is prevented from stopping rotation due to excessively low water levels, rotation energy of the water-raising waterwheel comes from the flow speed of the water in the pipelines, external power and a complete energy supply device are omitted, and the inspection well is convenient to construct.
Description
technical field [0001] The present invention relates to the technology of automatically supplying oxygen to sewage in urban sewage pipes, and in particular to an inspection well that relies on water flow to automatically supply oxygen to downstream sewage pipes. A pumping water truck built in the inspection well that relies on the power of water flow to rotate independently can continuously Oxygenates the sewage flowing through the main sewage pipeline in the inspection well, improves the dissolved oxygen level in the pipeline, and enhances the decomposition activity of aerobic microorganisms in the sewage, so that the organic pollutants are continuously consumed by microorganisms in the sewage flowing in the pipeline, so as to reduce pollution indicators, and the effect of purifying sewage. Background technique [0002] At present, the drainage system design mechanism of cities in our country is relatively complicated, especially in the old urban areas of the city. Due to t...
