Embodiment 1

[0030] The spiral flow plate is installed inside the municipal sewage pipeline, and the spiral flow plate is fixed at the center bottom of the municipal sewage pipeline through the spiral flow plate bracket. The center line of the municipal sewage pipe shall be kept horizontal; the diameter of the aeration air pipe shall be in the range of 100mm to 150mm, and shall be fixed to the bottom of the municipal sewage pipe through the support of the aeration air pipe, and shall be installed on one side of the spiral flow plate with a horizontal distance from the spiral flow plate at The range of 50mm to 100mm; the aeration nozzle is connected to the aeration air pipe at an angle of 45 degrees through the connecting pipe, and the inclination direction is opposite to the direction of the water flow; the upper end of the aeration nozzle reaches the middle of the spiral flow plate, and the aeration nozzle The distance is in the range of 100mm to 150mm; the aperture of the aeration nozzle ...

Embodiment 2

[0033] The composition of the anti-clogging spiral flow biological aeration municipal sewage pipeline of this embodiment is the same as that of Embodiment 1.

[0034] An anti-clogging spiral flow bio-aeration municipal sewage pipeline in this embodiment, when the sewage is full of 3 / 4, adjust the air volume control valve to control the volume ratio of air volume and water flow to 1:3, the sewage presents a spiral flow state, suspended The particles do not appear to settle; the sewage treatment effect is the same as that of Example 1.

Embodiment 3

[0036] The composition of the anti-clogging spiral flow biological aeration municipal sewage pipeline of this embodiment is the same as that of Embodiment 1.

[0037] A kind of anti-clogging spiral flow biological aeration municipal sewage pipeline of the present embodiment, when the sewage completely fills the sewage pipeline (that is, when the fullness is 1), the air volume control valve is adjusted to control the air volume and water flow volume ratio to be 1:4, The sewage presents a spiral flow state, and the suspended particles do not appear to settle; the sewage treatment effect is the same as that of Embodiment 1.

Abstract

The invention discloses an anti-blocking spiral-flow biological aeration municipal sewage pipeline, and relates to the field of municipal drainage and sewage treatment. The anti-blocking spiral-flow biological aeration municipal sewage pipeline is composed of a municipal sewage pipeline, a spiral-flow plate, a spiral-flow plate support, an aeration air pipe, an aeration air pipe support, a connecting pipe, an air volume control valve, an air volume meter, an aeration fan and an aeration pipe nozzle. The anti-blocking spiral-flow biological aeration municipal sewage pipeline has the following two characteristics in an operation process: firstly, through the structure design of the spiral-flow plate in the municipal sewage pipeline and the control of the aeration quantity, sewage in the municipal sewage pipeline is in a spiral flow flowing mode, so that the municipal sewage pipeline is prevented from being blocked; and secondly, organic matter in the sewage can be degraded by the aeration effect, so that biogas can be prevented from being generated by anaerobic fermentation of the sewage in the municipal sewage pipeline, and a certain biological treatment and purification effect is achieved on the sewage.

Description

technical field [0001] The technical solution of the present invention relates to the field of municipal drainage and sewage treatment, in particular to an anti-clogging spiral flow biological aeration municipal sewage pipeline. Background technique [0002] In the process of transporting urban sewage, the existing municipal sewage pipelines generally have relatively serious sewage pipeline blockage problems, which not only cause poor drainage of sewage in municipal sewage pipelines, but also lead to serious water accumulation on roads and cause environmental pollution. The solution to the clogging of traditional municipal sewage pipes mainly relies on manual dredging, which brings about heavy dredging work of sewage pipes, and produces methane due to clogging and sludge accumulation, resulting in frequent occurrence of methane poisoning incidents of dredging workers . [0003] CN207032424U discloses a kind of anti-clogging municipal sewage collection pipeline, which realiz...
