Embodiment 1

[0030] The spiral push flow type domestic sewage purification device in this example is as follows: figure 1 As shown, it is composed of an outer cylinder 8 and a central cylinder 11. The top of the outer cylinder 8 is a gas collection hood 2, and an air delivery pipe 1 is arranged on the gas collection hood 2; The inlet is connected to the sewage pipe; the outer cylinder 8 is provided with a spiral deflector 4, and the spiral deflector 4 spirals downward around the central cylinder 11 to the bottom of the outer cylinder 8; the top of the central cylinder 11 is higher than the top of the outer cylinder 8, The bottom of the central cylinder 11 is connected to the bottom plate of the outer cylinder 8, the bottom of the central cylinder 11 is provided with a central cylinder water inlet 5, the central cylinder water inlet 5 corresponds to the bottom of the spiral deflector 4, and the middle of the central cylinder 11 is provided with The water outlet pipe 10 is lower than the wa...

Embodiment 2

[0038] The inner diameter of the outer cylinder 8 of the spiral plug flow type domestic sewage purification device in this example is 2.5m, the cylinder height is 4.0m, and the height-to-diameter ratio is 1.6. The inner diameter of the central cylinder 11 is 0.9m, the width of the spiral deflector 4 is 0.8m, and the included angle with the horizontal is 25 ο , the vertical distance L between the two floors is 0.8m, and the saggy-height ratio of the gas collecting hood is 1 / 4.

[0039]The outer cylinder 8 is sealed to ensure that the spiral plug flow area 9 and the gas-gathering area 12 are in a strictly anaerobic state, and the upflow area 6 inside the central cylinder 11 is connected to the atmosphere to allow microorganisms to perform facultative oxygen treatment.

[0040] The total volume of the device in this example is about 24m 3 , suitable for joint account use.

[0041] All the other are the same as embodiment one.

Embodiment 3

[0043] The inner diameter of the outer cylinder 8 of the spiral push flow type domestic sewage purification device in this example is 2.5m, the cylinder height is 5m, and the height-to-diameter ratio is 2. The inner diameter of the central cylinder 11 is 0.5m, the width of the spiral deflector 4 is 1m, and the included angle with the horizontal is 23 ο , the vertical distance L between the two floors is 1m, and the saggy-height ratio of the gas collecting hood is 1 / 6.

[0044] All the other are with embodiment two.

Abstract

The invention belongs to a spiral flow pushing type domestic sewage purification device in the environmental protection field. The purification device is composed of an outer cylinder 8 and a central cylinder 11. A gas collecting hood 2 is arranged on the top of the outer cylinder 8, and a gas delivery pipe 1 is arranged on the gas collecting hood 2. A water distributing pipe 3 is arranged on the upper portion of the outer cylinder 8, and an inlet of the water distributing pipe 3 is connected with a sewage pipe. A spiral flow guiding plate is arranged in the outer cylinder 8 and is downwards coiled to the bottom of the outer cylinder 8 around the central cylinder 11. The top of the central cylinder 11 is higher than that of the outer cylinder 8, the bottom side of the central cylinder 11 is connected with a bottom plate of the outer cylinder 8, a central cylinder water inlet 5 is formed in the bottom of the central cylinder 11 and corresponds to the bottom of the spiral flow guiding plate 4, and a water outflow pipe 10 is arranged in the middle of the central cylinder 11 and lower than the water distributing pipe 3. A mud discharging pipe 14 is arranged on the bottom plate of the outer cylinder 8. The spiral flow pushing type domestic sewage purification device is high in effective capacity utilizing rate and purifying and treating efficiency and does not need additional power.

Description

Technical field: [0001] The invention belongs to the field of environmental protection, and in particular relates to a spiral push flow type domestic sewage purification device. Background technique: [0002] With the increasingly serious environmental pollution, the treatment of domestic sewage in villages and towns has attracted more and more attention. At present, most of the rural households in our country are in a state of scattered living, and the discharge of domestic sewage is neglected. Therefore, the unpowered self-operating small domestic sewage purification device suitable for single households or joint households has gradually developed into the main technology for the decentralized treatment of domestic sewage in China. , this type of device has also been promoted and developed to a certain extent, however, there are some problems in the space utilization efficiency and sewage flow control of the existing domestic sewage purification treatment device, mainly ...
