Biomembrane water purifying gate for aquaculture and in-situ water processing method of biomembrane water purifying gate

Abstract

The invention discloses a special biomembrane water purifying gate for aquaculture and an in-situ water processing method thereof. The biomembrane water purifying gate is made mainly according to the size of a pond and composed of at least two ropes tying multiple linear solid elastic fillers, and the linear solid elastic fillers form a carrier of a microorganism community so as to form a biomembrane; the biomembrane water purifying gate is directly arranged in the aquaculture pond; and the biomembrane water purifying gate is vertically suspended below the water surface of the pond and at a certain distance from the pond bottom. According to the invention, based on the characteristics of the aquiculture water environment in a pond (including a soil pond and a cement pond) and by using the biomembrane repairing technology and ecological principle, the biomembrane is applied to the in-situ repair of aquiculture water, influence of aquiculture pollutants on the bred animals and water environment is remarkably reduced, and water conservation, emission reduction, energy conservation, effect enhancement and sound growth of the bred animals are realized.

Description

technical field [0001] The invention relates to an aquaculture water treatment facility, in particular to a special biofilm water purification fence for aquaculture and an in-situ water treatment method for the biofilm water purification fence. Background technique [0002] The current aquaculture mode is mostly based on bait feeding, and eutrophication factors such as residual bait, feces, N, and P are discharged into the water body, so that ammonia nitrogen, nitrite nitrogen, chemical oxygen demand (COD), and biochemical oxygen demand in the aquaculture water body (BOD) etc. seriously exceed the standard, produce stress to farmed animals, increase the incidence of disease of farmed animals such as fish and shrimp and reduce output. Therefore, improving the water environment of aquaculture is an urgent problem to be solved in the production of aquaculture. [0003] The existing aquaculture water treatment system must be outside the pond culture water, and then occupy a cer...

AI Technical Summary

Problems solved by technology

[0003] The existing aquaculture water treatment system must be outside the pond culture water, and then occupy a certain area of ​​land to build a water treatment system. Usually at least three treatment unit pools need to be built: sedimentation tank, biological filter, sand (or other physical filter) Materials) filter ponds, etc., first, occupy a large area and need corresponding supporting water treatment facilities, resulting in large investment; second, the daily operation cost is high, due to some water treatment facilities and in order to form the water cycle between the treatment unit pool and the aquaculture water body Flow, etc. require power consumption

Therefore, it is difficult for the vast majority of aquaculture industry to accept this type of technology for productive application, which also leads to the fact that more than 95% of aquaculture sewage in my country is directly discharged without sewage treatment, making pond aquaculture the main source of pollution in my country One, causing increasingly serious eutrophication pollution in large areas of inland rivers and coastal waters
