Wetland ecological purification system and construction method thereof

Abstract

The invention discloses an ecological wetland provided with a vertical flow purification wetland. The ecological wetland comprises a wetland pond, a suspended box body, a lower partition plate, an upper partition plate and a water pump, wherein the suspended box body is arranged above the wetland pond. The ecological wetland is characterized in that: a box bottom plate is arranged at the bottom ofthe suspended box body; filter cotton is arranged between the lower partition plate and the box bottom plate; ceramsite is arranged between the lower partition plate and the upper partition plate; cultivation holes are evenly formed in the upper partition plate; water permeable baskets are placed in the cultivation holes; water plants or vegetables are planted in the water permeable baskets; water permeable holes are formed in the lower partition plate in the length direction of the lower partition plate. According to the ecological wetland, even if too much fish feed is fed, water pollution,oxygen deficit and eutrophication cannot be caused in the wetland, long-term ecological balance in the wetland can be maintained, long-term survival of organisms such as fishes in the wetland is guaranteed, and the purification effect of the wetland ecological purification system on water can be brought into full play.

Description

technical field [0001] The present invention relates to a wetland ecological purification system and a construction method thereof, more specifically, to a wetland ecological purification system provided with a vertical flow purification device and a construction method thereof. Background technique [0002] Wetlands have the effect of viewing and adding vitality to the environment. As a micro-ecological system, wetlands need to maintain the long-term survival of animals, plants and other organisms in the wetlands in order to perform the purification function of the wetlands, and keep the water in the wetlands always with sufficient content. Only when the amount of oxygen is needed can the respiration and metabolism of animals and aerobic organisms in the wetland be guaranteed. For the existing wetland ecosystem, in order to make the wetland economically valuable, fish that can generate economic value are usually raised in the wetland, and the fish that generate economic val...

Problems solved by technology

However, for the vast majority of people, it is impossible to grasp the amount of feed, and there are often situations where excessive feed is put in. Excessive feed will cause eutrophication of the water body in the wetland, and the microorganisms in the wetland cannot consume the excessive amount of water in the water body. The organic matter and ammonia nitrogen will reduce the oxygen content of the water body, which will easily cause the death of fish and other organisms in the wetland, resulting in the failure of breeding
