Embodiment Construction

[0022] like figure 1 As shown, a water distribution device for a large-scale constructed wetland sewage treatment system includes a regulating pool 1 and a water distribution pool 2. The shape of the regulating pool 1 is a cylindrical structure. The regulating pool 1 includes a base 12 of a gravel cushion and a wall of waterproof concrete. Body 8, a plurality of water distribution pools 2 are constructed on the outer edge of the regulating pool 1, and the preferred number of water distribution pools is 20. The water distribution pools 2 are connected with the wetland units one by one through the water distribution pipeline, and the wall of the regulating pool 1 is installed with water inlet pipes 11. The bottom of the regulating pool 1 is provided with an emptying pipe 9, the upper part of the wall of the regulating pool 1 is provided with an overflow pipe 10, and the water distribution pool 2 includes the base of the gravel cushion and the wall of waterproof concrete, such as ...

Abstract

The invention relates to a water-distributing device for a large-size artificial wetland sewage treatment system. A plurality of water-distributing tanks are constructed on the outer edge of an adjusting tank; the water-distributing tanks are in one-to-one correspondence with wetland units; a water inlet pipe is mounted on a wall of the adjusting tank; a discharging pipe is arranged at the bottom of the adjusting tank; each of the water-distributing tanks comprises a front unit of water-distributing tank and a rear unit of water-distributing tank; each front unit of water-distributing tank is separated from the adjusting tank through a wall; a water inlet of water-distributing tank is arranged on the wall; a water-distributing electrically operated valve is mounted at the water inlet of water-distributing tank; each front unit of water-distributing tank is communicated with the adjusting tank through the water inlet of water-distributing tank; each rear unit of water-distributing tank is separated from each front unit of water-distributing tank through the wall; a triangular weir is arranged on the wall; an adjusting baffle is mounted on the triangular weir; each rear unit of water-distributing tank is communicated with each front unit of water-distributing tank through the triangular weir; and a water-distributing pipeline is mounted in each rear unit of water-distributing tank. From pre-treating facilities to the artificial wetland main processing units, water can be uniformly distributed and reaeration is sufficient, so that the efficient treating capacity of the whole artificial wetland system can be brought into play.

Description

technical field [0001] The invention relates to a water distribution method for a large-scale constructed wetland sewage treatment system, and belongs to the technical field of environmental protection engineering and water treatment. Background technique [0002] With the rapid development of society and economy, the excessive consumption of natural resources, the deterioration of the ecological environment, especially the increasingly serious water pollution and eutrophication. In order to meet the requirements of sustainable development, it is urgent to find scientific, safe, convenient maintenance, economical and environmentally friendly means to treat sewage. [0003] At present, pollution source control and ecological restoration methods are mainly used for governance, and artificial wetlands are one of the important scientific methods. Constructed wetland is an evolving sewage land treatment technology. The basic principle of water purification technology in artifici...
