Description
Technical Field
The invention relates to the technical field of drainage systems, in particular to a whole-course odorless urban drainage system.
Background
Urban drainage systems are engineering facility systems for treating and removing urban sewage and rainwater, and are an integral part of urban public facilities. Urban drainage system planning is an integral part of urban overall planning. Urban drainage systems are generally composed of drainage pipelines and sewage treatment plants. Under the condition of diversion of sewage and rainwater, the sewage is collected by a drainage pipeline, sent to sewage treatment and then drained into water or recycled; after being collected by the drainage pipeline, the rainwater runoff is closely discharged into the water body.
Domestic sewage, excrement and the like in the urban drainage system are usually discharged into an underground septic tank through a sewer to be respectively stored, namely, solid residues are stored in one tank, and the domestic sewage is stored in the other tank; the domestic sewage is conveyed to a sewage treatment plant for purification treatment, and the purified sewage is discharged to surrounding natural water bodies; the excrement in the septic tank is sucked away by the septic tank through the excrement suction vehicle in some urban communities, and the excrement can be effectively treated and purified by other efficient sewage treatment systems which are arranged in the urban communities, so that the treated water quality can reach the discharge standard and is finally discharged into natural water. Rainwater in the urban drainage system is discharged into the drainage canal through a drainage outlet beside the road, then is discharged into the rainwater well through the drainage canal, and finally is discharged into the natural water body through a rainwater pipeline.
Urban residents generally consider that a pipeline for discharging domestic sewage can emit foreign odor when being blocked so as to influence the life experience of residents, but the odor can be easily ignored by a rainwater discharge system, when sundries such as fallen leaves, garbage, sludge and the like are accumulated in a drainage ditch below a rainwater inlet beside a road, organic substances are easily accumulated on the accumulated sundries, the organic substances comprise automobile emissions, food garbage and the like, malodorous odor can be generated when the organic substances are decomposed, and the malodorous odor is usually caused by compounds such as hydrogen sulfide, mercaptan and the like. The organic matter accumulated in the drainage ditch below each gully is usually not much, and even if the drainage ditch is not completely blocked, microorganisms are greatly propagated in the organic matter and decompose the organic matter, so that peculiar smell is emitted. People usually clean sundries accumulated in a drainage ditch below the gully regularly in a mode of treating the gully odor, and the odorizing source is directly taken away after the sundries are cleaned, so that organic substances are not easy to gather.
According to the related technology, even if sundries accumulated in the drainage ditch below the rain water inlet are cleaned, during subsequent rainfall, the rainwater still can convey the sundries on the road surface into the drainage ditch for accumulation, and then the accumulated and attached organic matters are accumulated again, the organic matters can emit odor again under the actions of temperature, humidity and microorganisms, and a city has thousands of rain water inlets, so that frequent cleaning of the drainage ditch can further cause heavy workload of sanitation workers for cleaning the drainage ditch.
