Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings.

[0020] Please refer to figure 1

[0021] In the present invention, the domestic wastewater in the community is concentrated into the sedimentation tank 3 through the wastewater recovery pipe network 1 for pretreatment, and the pretreated wastewater is lifted into the biochemical pool 4 through the automatic water lifting system 2 for biochemical treatment, and then The biochemically treated wastewater is discharged into the wetland purification zone 5, and the biochemically treated wastewater is repurified in the wetland purification zone by the cooperation of plants, fish and microorganisms in the zone.

[0022] Please refer to figure 2

[0023] The artificial wetland that uses self-circulation to purify the wastewater in the community includes: wastewater recovery pipe network 1, automatic water lifting system 2, and wastewater purification system. Waste water is...

Abstract

The artificial wetland that uses self-circulation to purify the wastewater in the community includes: waste water recovery pipe network, automatic water lifting system, and waste water purification system. Waste water is collected through the recovery pipe network, and the water head is raised through the automatic water lifting system to make the waste water in the waste water purification system. Form self-flow, and complete the purification of waste water in the waste water purification system. The automatic water lifting system is a water hammer pump, which lifts the waste water through the water hammer pump. While purifying the waste water, it can also generate electricity, and the waste water can be discharged to the national discharge Standard, not only saves the cost of wastewater treatment, but also saves water resources.

Description

technical field [0001] The invention relates to an artificial wetland, in particular to an artificial wetland which utilizes self-circulation to purify waste water in residential areas. Background technique [0002] Wetlands not only provide a variety of resources for human production and life, but also have huge environmental functions and benefits. Other systems have an irreplaceable role in other aspects, so wetlands are known as the "kidney of the earth". In the World Nature Conservation Program, wetlands, forests, and oceans are collectively called the three major ecosystems in the world. While pursuing urban efficiency one-sidedly, the functions and benefits of wetlands are ignored. Urban wetlands have reduced area, degraded functions, and serious pollution. In particular, the phenomenon of eutrophication is prominent, a large number of wetlands are eroded by the urbanization process, and industrial and domestic sewage make the water quality of urban wetlands continue...
