Complex microbial inoculant for water quality purification and application thereof

Abstract

The invention discloses a complex microbial inoculant for water quality purification. The complex microbial inoculant is compounded by bacillus subtilis mutant strain, Aspergillus niger mutant strain, Pichia pastoris mutant strain and lactic acid bacteria mutant strain which are in a ratio of (1-3):(1-3):(2-6): (3-9). The complex microbial inoculant for water quality purification, a preparation method and application thereof, provided by the invention has the beneficial effects that nitrite, ammonia nitrogen and other harmful substances in a water body can be rapidly degraded and pollutants can be decomposed rapidly; the bottom environment of a pond can be improved and the occurrence of diseases can be prevented effectively; meanwhile, the immunity of aquatic livestock can be enhanced and internal micro-ecological microflora balance of aquatic livestock can be regulated; the redox potential and DO (Dissolved Oxygen) at the bottom of the pond can be improved, the pH value of the water body can be stabilized, trace elements can be supplemented and the dynamic balance of plankton can be kept; and the growth of pathogenic microorganism in the aquatic water body can be inhibited.

Description

technical field [0001] The invention relates to the field of microbial preparations, in particular to a composite bacterial preparation for water purification and its application. Background technique [0002] In the past 50 years, nitrogen pollution has become a global pollution problem. The increase in the content of inorganic nitrogen compounds in the water environment has led to acidification and eutrophication of the aquatic ecosystem, which has brought a series of negative effects on aquatic animals. Therefore, research on nitrogen pollution The impact on aquatic animals is particularly urgent. [0003] With the rapid development of the world economy, the scale of the aquaculture industry continues to expand. However, the traditional aquaculture method one-sidedly pursues economic benefits, strengthens the input of energy substances outside the water system, and overfeeds, resulting in a large amount of metabolic waste in the water. In the process of aquaculture, beca...

Problems solved by technology

Objectively speaking, my country's fishery resources are rich, but the output is not high, the output value is not large, and the chain is not long

The main reason is due to the low utilization rate of suitable water surface and the low content of fishery technology
