Immobilized nitrifying bacteria capable of removing ammonia nitrogen in aquarium and preparation method of immobilized nitrifying bacteria

Abstract

The invention discloses immobilized nitrifying bacteria for removing ammonia nitrogen in an aquarium and a preparation method of the immobilized nitrifying bacteria. The immobilized nitrifying bacteria comprises polymeric hydrogel with a grid structure and activated nitrifying bacteria fixed in the grids. The polymeric hydrogel is formed through free radical polymerization of water-soluble acrylate monomers. The invention further discloses a using method of the immobilized nitrifying bacteria in the aquarium, and further provides a using position of immobilized nitrifying bacteria in the aquarium. According to the immobilized nitrifying bacteria for removing ammonia nitrogen in the aquarium, provided by the embodiment of the invention, the ammonia nitrogen removal rate reaches 95%. Ammonia nitrogen in the aquarium can be treated by using nitrifying bacteria particles, high simpleness and convenience and high easiness in implementation are achieved, and the ammonia nitrogen removal rate is high.

Description

technical field

[0001] The invention relates to a nitrifying bacteria in the field of environmental purification and a preparation method thereof, in particular to an immobilized nitrifying bacteria and a method for removing ammonia nitrogen in an aquarium. Background technique

[0002] During the process of breeding aquatic animals in the aquarium, the feces and residual bait of aquatic animals contain a large amount of nitrogen. The nitrogen in the water mainly exists in the form of ammonia nitrogen, nitrite, nitrate and organic nitrogen. The accumulation of ammonia nitrogen and nitrite in the water body will cause a sharp drop in dissolved oxygen in the water body, an increase in harmful gases, and a large number of harmful bacteria and opportunistic pathogens, resulting in outbreaks of aquatic animal diseases and a large number of deaths. Usually, ammonia nitrogen and nitrous acid in aquarium breeding wastewater are removed by filter purification materials, such as f...
