Abstract

The invention relates to a microbial water-purifying agent and a preparation method thereof. The microbial water-purifying agent is prepared by fermenting corncobs, sugar cane residue, wheat bran, rapeseed meal, zeolite powder, potassium dihydrogen phosphate, sodium chloride, light calcium carbonate, water and liquid strains in a fermentation bin. The preparation method of the microbial water-purifying agent comprises the following steps: firstly, crushing the corncobs into particles with diameters smaller than 5 mm; proportionally adding and mixing the sugar cane residue, the wheat bran, therapeseed meal, the zeolite powder, the potassium dihydrogen phosphate, the sodium chloride and the light calcium carbonate; adding 25 percent of water; sending the mixture to an air steamer; adding high-pressure steam to the air steamer to increase the air pressure to 1-2 MPa and the temperature to 140-200 DEG C; keeping the pressure for 4-6 minutes; momentarily releasing the mixture in the air steamer; sending the mixture to the fermentation bin so that the temperature falls to 30-37 DEG C; then, inoculating 3-5 percent of strains; fermenting in the fermentation bin for 72 hours; and discharging from the bin to obtain a finished product. The product has good water-purifying effect, and air-steamed stalks are culture media for strain growth as well as excellent vectors. The invention can prepare strains by strains, stimulate the mass propagation of microorganisms to form dominant strains and have the yield-improving efficiency.

Description

technical field [0001] The invention relates to the water quality purification technology of immobilized microorganisms, specifically adopting steam-exploded corncobs as the main immobilized carrier to carry out multi-strain mixed fermentation to produce microbial water purifiers for aquaculture water bodies and flowing water bodies and a preparation method. Background technique [0002] In recent years, the rapid development of the aquaculture industry has seriously deteriorated the aquaculture water body, resulting in a large number of aquaculture diseases. When it is discharged in large quantities, it will lead to eutrophication of the aquaculture water body and adjacent water bodies; on the other hand, although a large amount of urban sewage is treated by sewage plants, From time to time, excessive sewage flows into rivers and lakes, causing eutrophication, causing algae to grow wildly in the water body, and aquatic animals such as fish die due to lack of oxygen, which br...
