Problems solved by technology

The valve is large in size, high in cost, troublesome to use, and installing the valve at the water outlet of the constructed wetland will reduce the diameter of the water outlet and limit the flow, making it impossible to easily adjust the water level of the constructed wetland
Elbow adjustment is also based on experience, and it is impossible to control the water level of the constructed wetland
There is no report on the device for quantitatively regulating the water level of the constructed wetland. Therefore, the development and research of a simple and effective water level regulating device is of great significance for the operation of the constructed wetland.

Embodiment Construction

[0015] Attached below figure 1 And attached figure 2 The embodiments of the present invention are described in detail.

[0016] figure 1 and figure 2 Among them, 1-distribution pool or drainage ditch and outlet, 2-constructed wetland drainage pipe, 3-sleeve, 4-sealing ring, 5-sleeve off-line.

[0017] as attached figure 1 As shown, the constructed wetland drainage pipe 2 is composed of an elbow connecting a horizontal pipe and a vertical pipe. A coaxial casing 3 is arranged outside the vertical pipe of the drainage pipe, and a sealing ring 4 is arranged between the drainage pipe and the casing pipe, and the sealing ring is arranged at the top of the vertical pipe of the drainage pipe.

[0018] as attached figure 2 As shown, mark the scale on the vertical pipe of the drain pipe with the bottom of the drain pipe 2 as the 0 reference point. The sleeve 3 is of fixed length.

[0019] By sliding the sleeve up or down, the water level of the constructed wetland can be adju...

Abstract

The invention discloses a device for quantificationally regulating the water level of constructed wetlands. The device comprises a wetland drain-pipe, a water level regulating casing pipe and a water distribution trough, wherein the constructed wetland drain-pipe is arranged on the water distribution trough; the water level regulating casing pipe is sleeved on the drain pipe; and a sealing pad is arranged at the place where the drain pipe is sleeved with the water level regulating casing pipe. With the adoption of a casing pipe type water level regulating device, a communicator is formed between the drain pipe and the constructed wetland; the water in the constructed wetland is drained into the water distribution trough; when the water level regulating casing pipe is well positioned, the water in the wetland is higher than the height of the water outlet of the water level regulating casing pipe, the water flows out from the water outlet of the water level regulating casing pipe, then the water in the wetland is kept still the same as the height of the water level regulating casing pipe. As the drain pipe is provided with mark scales, the water level of the constructed wetland is the sum of the length of the casing pipe and the scale of a vertical tube. Therefore, the water level of the wetland can be regulated quantificationally by regulating the position of the casing pipe.

Description

technical field [0001] The invention belongs to the technical field of artificial wetland engineering. Background technique [0002] Constructed wetland is a new type of wastewater treatment technology. It is composed of gravel, pebbles, sand and other substrates, water distribution pipes, various wetland plants and pools. The purification of sewage by constructed wetlands is the absorption and utilization of constructed wetland plants and the adsorption of substrates. And the results of the joint action of microbial film on the fill in the wetland. Constructed wetland systems can generally be divided into three types according to the different water distribution methods or the different flow methods of sewage in them: free surface flow wetlands, horizontal subsurface flow wetlands and vertical flow wetlands. Different types of constructed wetlands have different water levels, plants in constructed wetlands and microorganisms in the substrate have different living environme...
