Complex active bacterial biological water purifying a gent and method for preparing same

Abstract

The invention discloses a composite live bacterial organism purifying agent and a method for the production thereof, the biological purifying agent contains Bacillus subtilis KX-1 CCTCC No. M 208057, Bacillus subtilis KX-2 CCTCC No. M 208058, and Bacillus subtilis KX-4 CCTCC No. M 208060, and the total bacteria count is larger than 1x10<8>CFU/g. The biological purifying agent can effectively remove ammonia nitrogen and nitrite in water and improve the water pollution; and degrade organic macromolecules and reduce the rich nutrition level in water; and the three bacilli can decompose organic macromolecule matters in water into saccharide, amino acid, vitamin, bioactive substances (hormone), etc. that can be absorbed by animals and plants, thereby realizing the complementary nutrition and harmonious symbiosis, and forming a complex and stable microbial system in water by proliferation.

Description

technical field [0001] The invention belongs to the technical field of microbial inoculum, is applied to water pollution environment control and purification treatment of liquid discharges from aquaculture and other farms, and specifically relates to a microbial water purification inoculum containing beneficial living bacteria and a preparation method thereof. Background technique [0002] Water pollution is a worldwide water environment problem. Although my country's water resources and environmental protection has made positive progress, the situation is still grim. On the one hand, urban pollutant emissions far exceed the environmental capacity. On the other hand, in aquaculture, as the excrement of animals increases, a large amount of toxic substances are produced under the action of spoilage bacteria. Similarly, liquid discharges from other farms also have such problems. [0003] As one of the high and new technologies, biotechnology has a long history in water pollut...

Problems solved by technology

However, this kind of composite bacterial agents has limitations to varying degrees, such as poor applicability, and can only be used for some specific toxic wastewater or high-concentration wastewater with a single component; the production cost of some of them is too high, such as nitrifying bacteria ; In particular, the degradability is limited, the sustainability is poor, and it is often required to add, which also increases the cost
