Problems solved by technology

However, there are also major limitations. In general, the microorganisms introduced into the system are scattered in the water body, "dwelling without a fixed place", and the stability of the community is not high. It is difficult to compete with the indigenous microorganisms and become the dominant species for a long time.

Abstract

The invention discloses an aquaculture water purifying agent. The aquaculture water purifying agent comprises the following components in part by weight: 5 to 20 parts of tourmaline, 20 to 60 parts of montmorillonite, 100 to 500 parts of zeolite, 5 to 30 parts of molasses, 0.5 to 5 parts of phosphate, 0.1 to 1 part of tryptophan and 10 to 50 parts of microbial agent. The purifying agent is compounded by using the microbial agent, mineral biological activating agents and nutrient elements; and the tourmaline, the montmorillonite and the zeolite can promote microbe growth and metabolic activity, and can be attached to or fix microbes to play a barrier protection role. The nutrient elements can regulate the carbon nitrogen ratio balance of the water and promote the growth and the degrading effect of the microbes, and the zeolite and the montmorillonite are good controlled release carriers and have remarkable controlled release effect on the nutrient elements. The purifying agent can strengthen and activate the metabolic activity and the environmental adaptability of the microbial agent; and by compounding the minerals and the nutrient elements, the optimal ecological environment of microbe degradation is regulated and controlled, a biodegradable micro-ecological system for constructing the culture water is optimized and biological repair of the water is promoted.

Description

technical field [0001] The invention relates to a purifying agent, in particular to an aquaculture water purifying agent. Background technique [0002] my country has formed the largest aquaculture industry in the world. However, behind the rapid development of China's aquaculture industry, we must face the fact that the environment of aquaculture waters is facing continuous deterioration, and water quality pollution and disease breeding have increasingly plagued the aquaculture industry. Aquaculture pollution has caused varying degrees of damage to the ecological environment, environmental waters, and biodiversity. It has brought huge losses to the fishery economy and seriously threatened the quality and safety of aquatic products. [0003] Microbe-based bioremediation technology is widely used in aquaculture water quality control. There is a micro-ecological system composed of diverse microorganisms in the aquaculture water body. In most cases, the natural conditions of...
