Description

TECHNICAL FIELD

[0001] The utility model relates to the field of artificial wetland water inlet channel, especially to an artificial wetland water inlet channel preventing blockage. BACKGROUND

[0002] Artificial wetland is a kind of ground similar to marsh constructed and controlled by people, mainly used for sewage treatment, which utilizes the physical, chemical and biological triple synergies of soil, artificial medium, plants and microorganisms to purify sewage through adsorption, retention, filtration, oxidation and reduction mechanisms.

[0003] The artificial wetland water inlet channel is an important part of the artificial wetland system, and its main function is to introduce the sewage to be treated into the interior of the wetland. The design of the water inlet channel needs to consider the flow and velocity of the sewage and the treatment capacity of the wetland system to ensure that the sewage can enter the wetland uniformly and stably, thereby improving the treatment efficiency of the wetland system. The existing artificial wetland water inlet channel has the problem that the residence time of the effluent in the water inlet channel is too long, and the silt deposition causes the blockage of the artificial wetland water inlet channel, which seriously affects the operation and maintenance of the wetland and the quality of the effluent.

[0004] Therefore, in view of the above-mentioned existing artificial wetland water inlet channel, a kind of artificial wetland water inlet channel preventing blockage can be designed to increase the water passage, which ensures the flow of effluent and saves the filler. SUMMARY

[0005] In order to overcome the problem of the existing artificial wetland water inlet channel that the residence time of the effluent in the water inlet channel is too long, and the silt deposition causes the blockage of the artificial wetland water inlet channel, which seriously affects the operation and maintenance of the wetland and the quality of the effluent.

[0006] The technical scheme of the utility model is as follows: an artificial wetland water inlet channel preventing blockage, comprising a pool body, a water inlet pipe, a flow dividing wall, a water passing wall, a gate valve module, a wetland area, a water collecting area and a flow dividing area; the pool body is linearly provided with a flow dividing wall for guiding the flow of water inlet and a water passing wall for preventing blockage and dividing flow; the flow dividing wall and the pool body form a water collecting area, the flow dividing wall and the water passing wall form a flow dividing area, the water passing wall is provided with a gate valve module for controlling the flow of drainage, and the water collecting area is provided with a water inlet pipe passing through the pool body for water inlet.

[0007] Preferably, the diversion wall for guiding the flow of water inlet and the water-passing wall for preventing siltation are linearly and integrally formed in sequence within the pool body. The pool body is divided into a water collection area, a diversion area, and a wetland area. Using a gate valve module located on the water-passing wall, the drainage flow is controlled, ensuring smooth water flow through the artificial wetland, proper positioning of the partition trough, and overall subsurface flow in the wetland. This effectively purifies phosphorus and nitrogen, promotes healthy growth of aquatic plants, maintains the station's appearance, and allows irrigation water to be drawn from the water collection and diversion areas, achieving resource utilization, extending the effective lifespan of the wetland, and realizing cost reduction and efficiency improvement.

[0008] As a preferred option, a wetland area is formed between the water-passing wall and the pool body. The bottom of the wetland area, the water collection area and the diversion area are all equipped with pebble groups for separating silt. The upper end of the pool body is surrounded by mounting holes for installing guardrails. Through the mounting holes, protective fences can be installed to ensure the appearance of the station.

[0009] Preferably, the diversion wall is provided with corrugated grooves running through it from bottom to top, and water flow holes are provided running through it horizontally between the two sets of corrugated grooves. Water flows through the corrugated grooves and water flow holes running through it from bottom to top, forming multiple directions of diversion into the diversion area.

[0010] As a preferred embodiment, the water passage wall is composed of multiple sets of porous brick masonry. The water passage wall has a first diversion hole and a second diversion hole that are horizontally distributed and intersected. The center of the water passage wall has a hollow groove corresponding to the gate valve module.

[0011] As a preferred option, a water channel is provided on the water passage wall. The water channel is set 20cm down on the water passage wall, and the overall height of the water passage wall is 30cm. The 30cm water channel is built at the water inlet channel with perforated bricks. This ensures the flow of water out and saves on filler.

[0012] As a preferred option, the diversion wall and the water passage wall are integrally formed with the pool body. The two ends of the water passage wall are provided with limit holes for corresponding gate valve modules at the connection with the pool body. The positioning push rod can be positioned through the limit holes.

[0013] Preferably, the gate valve module includes a balance plate, a gate, a push rod, and a cylinder. Both ends of the balance plate are vertically inserted with push rods that enter the limit hole. The upper end of the push rod is equipped with a cylinder. The center of the balance plate is equipped with a gate. The cylinder drives the push rod to move the gate up and down. The top of the cylinder is equipped with an electric control switch. When control is performed, the cylinder drives the push rod to move the gate up and down.

[0014] The beneficial effects of this utility model are:

[0015] 1. Unlike existing constructed wetland inlet channels, which suffer from sludge buildup and blockage due to prolonged water retention, this new system features a linear, integrated design within the wetland. The inlet channel is divided into a collection area, a distribution area, and a wetland area. Gate valve modules on the distribution walls control drainage flow, ensuring smooth water flow through the constructed wetland, maintaining normal water levels in the isolation tanks, and achieving subsurface flow throughout the wetland. This effectively purifies phosphorus and nitrogen, promotes healthy aquatic plant growth, and maintains the wetland's appearance. Irrigation water can be drawn from the collection and distribution areas, enabling resource utilization, extending the wetland's effective lifespan, and achieving cost reduction and efficiency improvement.

[0016] 2. During diversion, water enters through the inlet pipe, and the water flow gradually increases, filling the collection area. Subsequently, the water flows through the corrugated grooves and flow holes in the diversion wall from bottom to top, forming multiple directions of diversion into the diversion area. The diversion state is used to avoid clogging in the collection area. The electric control switch drives the cylinder to drive the push rod to raise the gate to a certain position, controlling the water flow. The water flows through the first diversion hole, the second diversion hole and the water channel on the water wall, flowing into the wetland area in sequence. The entire wetland achieves subsurface flow, effectively purifying phosphorus and nitrogen. Attached Figure Description
