Granular composite bottom treatment bacterium and preparation method thereof

Abstract

The invention provides a granular composite bottom treatment bacterium and a preparation method thereof. The formula of the composite bottom treatment bacterium comprises the following components: 0.5-1.5% of photosynthetic bacterium flocculant, 0.1-1% of liquid Bacillus natto, 35-53% of bentonite, 35-53% of granular zeolite powder, 1-5% of attapulgite, 2-6% of sodium percarbonate, 0.5-1.5% of sodium dihydrogen phosphate and the balance of normal saline. The preparation method comprises the following steps: evenly sprinkling the photosynthetic bacterium flocculant and the liquid Bacillus natto on the zeolite powder, evenly mixing, adding the bentonite, and then mixing; evenly mixing the sodium percarbonate, the sodium dihydrogen phosphate and the attapulgite; and mixing the two mixtures obtained in the previous steps, adding the normal saline, sufficiently stirring and mixing, putting in a granulator, and granulating. According to the invention, the viable granular composite bottom treatment bacterium has a high survival rate, can quickly sink to the bottom after being directly sprinkled, has remarkable cracking effect when encountering water and is convenient to use; sludge at the bottom of a pool can be quickly decomposed and degraded into organic substances; harmful substances can be effectively adsorbed; the acidity of a water body can be reduced, the pH value of the water body can be stabilized, minor elements can be supplemented, and the transparency of the water body can be enhanced; and bottom sediments can be improved, and water can be purified.

Description

technical field [0001] The invention belongs to the technical field of microbial treatment for aquaculture water purification, and relates to a granular compound bottom-modifying bacterium and a preparation method thereof. Background technique [0002] Sea and freshwater aquatic animal nursery ponds and grow-out ponds, especially ponds with a lot of silt bottom, often due to years of silt that has not been cleaned, the mud at the bottom of the pond is aging, the water quality is black and smelly, and aquatic animals such as fish and shrimp die in ponds. Contents of the invention [0003] The purpose of the present invention is to provide a method that can quickly increase the oxidation-reduction potential and dissolved oxygen at the bottom of the pool, decompose the sludge at the bottom of the pool, degrade residual bait, feces, animal and plant corpses and organic debris at the bottom of the pool, and can effectively adsorb ammonia nitrogen and nitrous acid at the bottom o...
