A multifunctional ecological purification system for large-scale circulating aquaculture water

Abstract

The invention relates to a multifunctional ecological purification system for large-scale circulation breeding water, which is used for exchanging water in a pond and purifying the breeding wastewater in the pond. The purification system comprises an efficient precipitation and filtration region, an ecological breeding purification region, an artificial wetland purification region, a water collecting pond and an automatic water quality monitoring and regulating device, wherein the efficient precipitation and filtration region, the ecological breeding purification region and the artificial wetland purification region are used for purifying a water body, and the automatic water quality monitoring and regulating device is used for monitoring the quality of the water body in the purification system and controlling operation of the purification system. Compared with the prior art, the system can be used for automatically monitoring the water quality in the system, so that water in the pond can satisfy the requirements of aquaculture water after being subjected to circulation treatment of the purification system. Meanwhile, aquatic animals and plants and bottom mud generated in the purification system can be recycled. The system provided by the invention can be applied to purifying large-scale aquaculture wastewater and has good economic and environmental benefits.

Description

technical field [0001] The invention belongs to the field of aquaculture technology and water treatment technology, and specifically relates to a multifunctional ecological purification system for large-scale circulating aquaculture water. Background technique [0002] With the rapid development of my country's aquaculture industry, the aquaculture method has gradually changed from the traditional extensive breeding model to large-scale and intensive farming, which has greatly improved the output and quality of aquatic products. Due to the large amount of water, if the aquaculture tail water is discharged indiscriminately without treatment, it will pollute the water environment and waste water resources. Usually, nitrogen and phosphorus nutrients, dissolved organic matter, suspended solids and pathogens in aquaculture wastewater are the focus of treatment, especially ammonia nitrogen and nitrite nitrogen that are toxic to aquatic products. Scholars at home and abroad have co...

AI Technical Summary

Problems solved by technology

[0006] The wastewater produced by aquaculture contains a lot of nutrients such as nitrogen and phosphorus, and with the discharge and treatment of wastewater, a lot of nutrients are wasted

Therefore, it is also necessary to pay attention to the recycling and utilization of resources in wastewater and sediment while treating aquaculture wastewater, but currently less attention has been paid to this aspect
