Problems solved by technology

[0002] At present, the molasses alcohol waste mash discharged from all sugar factories is high-concentration organic heavy-acid high-load polluted wastewater, and its COD is as high as 80,000-120,000 mg / L. If the sewage is directly treated, it will not only cost a lot of money, but it is really difficult to meet the standard
If this heavy acidic waste mash flows into acidic soil, it will aggravate the deterioration of soil quality, make the soil harden, and even damage the roots, stems and leaves of plants.

Embodiment 1

[0014] Example 1 The high-temperature Bacillus coagulans bacterial liquid (>1×10 7 / ml) evenly mixed into the bagasse, then put into a woven bag, and fixed at the outlet of the high-temperature waste mash. After the waste mash is filled with the pool, the liquid temperature drops below 45°C, and 0.5% of the waste mash is added to produce alkali Bacillus 0841 and Alcaligenes faecalis 01720 (1:1) mixed bacterial solution (>1×10 7 / ml) ferment for more than 72hrs at an aeration rate of 5m3 / hr, and when the pH reaches 5, add 0.5% of the waste mash to Bacillus peptiformis, Bacillus megaterium and Rhizobium radiata (1:1:1) Mixed bacteria solution (>1×10 7 / ml) was fermented at 5m3 / hr ventilation for 72~96hrs, the waste mash liquid was applied to sugarcane field at 10 tons / mu, and tea, bananas, etc. were applied at more than 1 ton / mu, and the yield increase rate was more than 10~15%.

Embodiment 2

[0015] Example 2 After the tank is filled with high-temperature waste mash, add high-temperature Bacillus coagulans bacterial liquid with 0.5% waste mash, and when the liquid temperature drops below 45°C, add Alcaligenes 0841 and feces with 0.5% waste mash The mixed bacterial liquid of Alcaligenes 01720 is fermented for more than 72hrs under the ventilation rate of 5m3 / hr, and when the pH reaches 5, the mixed bacteria of Bacillus peptiformis, Bacillus megaterium and Rhizobium radiata with 0.5% of the waste mash are added liquid, under 5m3 / hr aeration rate, fermented 72~96hrs, and this bacterium liquid all has more than 10~15% yield increase rate on different crops according to example 1 application rate.

Embodiment 3

[0017] Put the barreled high-temperature coagulum Bacillus coagulans liquid (>1×10 7 / ml), when the high-temperature waste mash above 90°C is just discharged, it flows into the waste mash from the outlet through a straw, and the others are injected into the pool mouth at the same time. When the liquid temperature drops to 45°C, add 0.5% of waste mash The mixed bacterial solution of Alcaligenes 0841 and Alcaligenes faecalis 01720 was fermented for 80hrs at an aeration rate of 5m3 / hr. When the pH reached 5, the same fertilizer-effect mixed bacterial solution was added according to the above ratio. Under the same aeration rate, , Fermented more than 80hrs, this bacterium liquid is applied on the same crop according to embodiment 1, all has the effect of increasing production of about 15%.

Abstract

The invention discloses a method for preparing a fertilizer effect type molasses alcohol waste mash bacterial liquid through triple fermentation. The method comprises steps of: inoculating high-temperature bacillus thermocoagulans Sp.nov. into a high-tempreature (90 DEG C) molasses alcohol waste mash which is just discharged to be fermented preferentially so as to prevent the waste mash from getting smelly in a cooling process due to putrefying bacteria contamination; cooling the waste mash to be below 45 DEG C, and then inoculating strains of Alicaligenes ACCC 02841 and strains of Alicaligenes faecalis ACCC 01720 for secondary fermentation so as to improve the pH of the waste mash; and finally, adding Bacillus macilaginosus, BacillusmegateriumGMCC 1.270 and Rhizobiumradiobacter for the third fermentation, thus preparing the organic waste mash bacterial liquid which is safe and odor-free and has a lasting fertilizer effect. The waste mash bacterial liquid after triple fermentation can be fully used as an agricultural liquid fertilizer, is safe and odor-free, realizes zero emission of the waste mash and is an organic bacterial liquid fertilizer which is popular with most peasants. Applications of a plurality of sugar mills prove that the bacterial liquid can replace at least more than half of the application amount of a chemical fertilizer; and by utilizing the bacterial liquid, soil is improved, the rhizosphere active fertility is increased, and plant diseases and insect pests are reduced.

Description

technical field [0001] The present invention is designed to solve the effective utilization of zero discharge of heavy acidic molasses alcohol waste mash in sugar factories, specifically three fermentation processes are carried out with high-temperature bacteria, Alcaligenes bacteria and nitrogen-phosphorus-potassium fertilizing bacteria. Background technique [0002] At present, the molasses alcohol waste mash discharged from all sugar factories is high-concentration organic heavy-acid high-load polluted wastewater, and its COD is as high as 80,000-120,000 mg / L. If it is directly treated with sewage, it will not only cost a lot of money, but it is really difficult to meet the standard. If this heavy acidic waste mash flows into acidic soil, it will aggravate the deterioration of soil quality, compact the soil, and even damage the roots, stems and leaves of plants. It is imperative to reduce its acidity (increase pH) and develop and utilize it comprehensively. Contents of ...
