Ecological restoration method for penaeus vannamei boone aquaculture water body

Abstract

The invention relates to an ecological restoration method for Penaeus vannamei breeding water, comprising: collecting the tail water from the culture into a tail pond, using the self-settling effect of the water body to initially purify the residual bait and excrement, and then entering the ecological purification pool, and floating plants on the water surface The bionic water plant system is used for biological purification, and then the water pump is used to pump the purified water into the automatic filter for micro-mesh filtration, and then the water body is sterilized by the ultraviolet sterilization box, and then re-enters the aquaculture pond. Aiming at the problems of excessive total nitrogen, nitrite nitrogen and ammonia nitrogen concentration and high turbidity in the culture water of Penaeus vannamei, the present invention adopts technologies such as self-settling, floating plant absorption, bionic aquatic plant system purification, micro-mesh filtration and ultraviolet sterilization to remove large Part of the residual bait and excrement reduces the concentration of ammonia nitrogen and nitrite nitrogen, controls the excessive growth of algae, reduces the turbidity of the water body, improves the landscape effect and economic benefits at the same time, increases the ecological diversity of the aquaculture water body, and has a good application prospect .

Description

technical field [0001] The invention belongs to the field of aquaculture water treatment, and in particular relates to an ecological restoration method for aquaculture water of Penaeus vannamei. Background technique [0002] Although the output and scale of Penaeus vannamei aquaculture in China has ranked first in the world in recent years, it still faces serious problems of sustainable development. Farmers are blindly pursuing high yields and high benefits, and the aquaculture area is constantly expanding and the aquaculture output is constantly increasing. As a result, a large amount of aquaculture wastewater is discharged, toxic and harmful algae and bacteria reproduce in large numbers, the eutrophication of the aquaculture environment is intensified, the water body is severely damaged, and there are more and more types of pathogens, the harm is increasing, and the sustainable development of aquaculture is seriously affected. [0003] The vannamei farming area in Nantong ...

Problems solved by technology

[0011] The technical problem to be solved by the present invention is to provide a method for ecological restoration of Penaeus vannamei aquaculture water body, the method aims at the problems of excessive nutrient salt concentration such as total nitrogen, nitrite nitrogen and ammonia nitrogen in the culture water body of Penaeus vannamei and high water turbidity, Adopting technical methods such as self-settling, floating plant absorption, bionic aquatic plant system purification, micro-mesh filtration and ultraviolet sterilization, most of the residual bait and excrement have been removed, the concentration of ammonia nitrogen and nitrite nitrogen has been reduced, and the growth of algae has been inhibited. Increase the turbidity of the water body, improve the landscape effect and economic benefits at the same time, increase the ecological diversity of the water body, and have a good application prospect
