Problems solved by technology

[0003] In the existing technology, the combination of water collection pipes and underground pipe galleries is often used to collect and utilize rainwater. Usually, multiple water collection wells are set in the pipe gallery to collect rainwater and accumulated water in the pipe gallery. However, the rainwater falls Sometimes it will be mixed with dust in the air, and a certain amount of sand will be mixed with the houses and the ground when it is washed. This situation is especially serious in northern cities with strong wind and sand. The sediment in the well will greatly reduce the water storage capacity of the water collection well, and in severe cases, it will paralyze the drainage system of the entire city

Embodiment 1

[0047] see Figure 1-Figure 14 , a continuous urban sewage treatment device, comprising a pipe gallery and a rainwater collection pipe 2 and a drainage pipe 1 arranged in the pipe gallery, the rainwater pipe is connected to the drainage system on the ground, the bottom of the pipe gallery is inclined in the middle, and the center of the bottom surface of the pipe gallery There is also a water collection tank 5 at the position, and a filter plate 6 is arranged on the water collection tank 5, and the water collection tank 5 is arranged obliquely along the length direction of the pipe gallery; there are multiple drainage sections in the pipe gallery, and a water collection well 3 is provided in any drainage section And collecting silt well 14, also be provided with mud cake drying well 18, mud cake drying well 18 is arranged on silt collecting well 14 side; There is a cover plate 4, and an inner filter plate 1213 is arranged in the water collection well 3. The inner filter plate ...

Embodiment 2

[0053] A method for continuous treatment of urban sewage, comprising the following steps:

[0054] S1. Start the stirring device 8 and the air pump 10; the stirring drum 803 rotates, and the spiral plate 804 at the lower part of the stirring drum 803 lifts the silt deposited at the bottom of the sump 3, while the stirring rod 806 at the upper part stirs to mix the muddy water in the sump 3 Simultaneously, the air pump 10 continues to ventilate in the stirring shaft 801 by pipeline, when the auxiliary air hole 805 on the stirring drum 803 is aligned with the main air hole 802 on the stirring shaft 801, the gas in the stirring shaft 801 is discharged, and the mixing of muddy water is accelerated.

[0055] S2. Start the sewage pump 11, the sewage pump 11 transports the mud-water mixture to the exhaust device 12 through the pipeline, and the heating pipe in the exhaust device 12 heats the passing mud-water mixture, and the gas dissolved in the mud water is formed by air bubbles 121...

Embodiment 3

[0061] see Figure 16 , a continuous treatment device for urban sewage, the only difference from Embodiment 1 is that there are two reversing gears 1508, and the two reversing gears 1508 are symmetrically arranged in the lifting box 1504 up and down.

Abstract

The invention belongs to the technical field of urban sewage treatment and recycling, and discloses an urban sewage continuous treatment device and a treatment method thereof. The device comprises a pipe gallery, a rainwater collecting pipeline and a drainage pipeline, the rainwater collecting pipeline and the drainage pipeline are arranged in the pipe gallery, a plurality of drainage intervals are arranged in the pipe gallery, a water collecting well and a silt collecting well are arranged in each drainage interval, a desilting device and a washing device are arranged in each water collecting well, a mud-water separator connected with the desilting device is arranged on each silt collecting well, and a cake pressing device is arranged in each silt collecting well; the treatment process comprises the steps of mud-water mixing and stirring, exhausting, mud-water separation, mud cake forming, drying and the like, the problem that in the prior art, the water storage capacity of silt obtained after rainwater precipitation is reduced is solved, and the obvious effects that mud-water separation and mud cake forming can be achieved, and follow-up water resource treatment and utilization are facilitated are achieved.

Description

technical field [0001] The invention relates to the technical field of urban sewage treatment and resource utilization, in particular to a continuous urban sewage treatment device and a treatment method thereof. Background technique [0002] Cities and industrial enterprises produce a large amount of domestic sewage and industrial wastewater every day, as well as a large amount of rainwater brought by precipitation. Compared with domestic sewage and industrial wastewater, rainwater has a higher degree of cleanliness and can be used for irrigation and flushing after simple treatment. Simple uses such as pavement; in fact, rainwater harvesting and utilization systems have been used for decades abroad, such as the rainwater harvesting and utilization system of the Century Dome in London, the rainwater harvesting in Berlin, the rainwater utilization in Nigeria and Denmark, and the rainwater has been treated simply Afterwards, it can be used for flushing toilets in block apartmen...
