Ecological water purification material for aquaculture

Abstract

The invention discloses an ecological water purification material for aquaculture. The ecological water purification material comprises a base film layer, a substrate support layer, a microbial preparation layer and a protective surface layer, wherein the substrate support layer and the microbial preparation layer are sequentially arranged on the base film layer from the bottom up; the base film layer is coated with the substrate support layer and the microbial preparation layer through the protective surface layer. A microbial preparation adopted in the invention is used for reducing pollutants in the water caused by culture, does not cause secondary pollution to the water, does not affect the growth of living things in the water and does not cause the accumulation of substances toxic to fishes and shrimps in the water; the microbial preparation layer is composed of bacillus amyloliquefaciens, bacillus laterosporus, lactobacillus acidophilus, nitrifying bacteria, denitrifying bacteria, bacillus subtilis and bacillus licheniformis, can be safely applied to pollution-free aquaculture and can effectively degrade harmful substances generated by self-pollution during aquaculture in the water.

Description

technical field [0001] The invention relates to a water purification material, in particular to an ecological water purification material for aquaculture, belonging to the technical field of water treatment. Background technique [0002] Statistics show that global per capita fish consumption has doubled in the past 50 years. However, due to the serious intervention of human activities on nature, such as environmental damage and overfishing, the number of most wild populations has decreased sharply, and even is on the verge of extinction. Therefore, aquaculture has become the main force in the supply of aquatic products in the future. According to statistics, in the past 30 years, the production of aquaculture has increased by 10 times. However, with the increase in production, problems have gradually appeared in traditional pond aquaculture in my country, mainly manifested in: high-density aquaculture, large amounts of feed and fish medicines, resulting in a large amount o...

Problems solved by technology

After analyzing the advantages and disadvantages of these methods, it is believed that the physical restoration method often requires a large amount of manpower and material support; the chemical restoration method has high cost, unstable effect, and easy to cause secondary pollution, etc. Even more toxic products will be produced; and bioremediation has low cost and can also play a role in the restoration of water ecological functions, etc., and will be the main restoration method in the future
