Water quality purification bacterium agent from mix fermentation production with multiple bacterials and production method thereof

Abstract

The invention relates to a water purification microbial inoculum which is produced by blending and fermenting a plurality of bacteria. Straws are taken as raw materials and then seed solutions of a plurality of bacteria, a straw fermention medium and a concentrated nitrifying bacteria solution are added, thus obtaining the water purification microbial inoculum. A preparation method of the water purification microbial inoculum comprises the steps as follows: the straws are sent to a material steam explosion system and then a steam explosion is conducted to the straws; after the steam explosion, the straws are sent to a chelated reaction storage for reaction; after reacting in the chelated reaction storage, the straws are sent to a fermention storage for fermentation; 5 percent of the seed solution of a plurality of sporos and 30 percent to 40 percent of the straw fermention medium are added to the fermention storage; and before the straws are taken out of the storage, 2 percent to 3 percent of the concentrated nitrifying bacteria solution is added and stirred evenly, thereby obtaining the water purification microbial inoculum. The water purification microbial inoculum has the advantages that the valid viable bacteria number of the produced water purification microbial inoculum reaches 2 billion / g (slab) and nitration and subnitration can be realized; a purifier has comprehensive water purification functions which can effectively restrain the harmful bacteria of a cultured water body, thereby realizing the disease prevention and survival rate improvement; the degradation of the organic pollutant in the water body can be accelerated; and ammonia nitrogen can be decreased and dissolved, and oxygen can be increased, thereby achieving the aims of increasing production and income.

Description

technical field

[0001] The invention relates to the technology of microbial water purification, in particular to the production of an ecological preparation for purifying aquaculture water by multi-bacteria mixed fermentation and a preparation method. Background technique

[0002] my country is the largest aquaculture country in the world, and aquaculture accounts for about 70% of the world's total. However, the biggest threat to the aquaculture industry is that the aquaculture water body deteriorates year by year, which leads to the occurrence of aquaculture diseases and virtually increases the cost of aquaculture for disease prevention and treatment. Although some microbial water purifiers are currently being promoted, due to the low number of bacteria, high cost, and poor purification effect. Contents of the invention

[0003] The purpose of the present invention is to screen out a group of microbial flora with strong ability to purify water quality, use cheap steam-exp...
