Example Embodiment

[0017] Example 1

[0018] The collected food wastes are crushed and sorted to remove inorganic substances. When cooking at 95°C, 0.01% high temperature resistant amylase (high temperature resistant α-amylase from Bacillus licheniformis, 40000U / g, purchased from Novozymes A / S company) and keep it for 2 hours. After the oil is poured out, add 0.03% glucoamylase (100000 U / g, purchased from Novozymes A / S company) when the temperature drops to 55℃, keep it for 2 hours; when the temperature drops to 37℃, respectively Add 0.01% protease (100000 U / g, purchased from Novozymes A / S) and 0.01% cellulase (100000 U / g, purchased from Novozymes A / S), which accounts for the weight of food waste The kitchen waste liquid is kept for 3 hours and separated from solid and liquid. The liquid is pumped into the fermentation tank. The high temperature sterilization condition is 121℃, sterilization for 25min. When the temperature is lowered to 35℃, the inoculation rate is 5% Bacillus subtilis and lichen ...

[0022] Example 2

[0023] After the collected food waste is crushed and sorted to remove inorganic matter, add 0.05% high-temperature amylase (40,000 U / g, purchased from Amano Enzyme Inc.) when cooking at 90°C and keep it warm for 1-2 hours, then pour out the grease Then, add 0.05% glucoamylase (100000U / g, purchased from Novozymes A / S) when the temperature drops to 60°C, and keep it warm for 2 hours; when the temperature drops to 40°C, add 0.03% protease ( 100000U / g, purchased from Novozymes A / S company) and 0.03% cellulase (100000U / g, purchased from Novozymes A / S company), which accounts for the weight of food waste, work together with kitchen waste liquid, and solid-liquid after 3 hours of heat preservation Separate and pump the liquid into the fermentation tank. The high-temperature sterilization conditions are 115℃, sterilization for 30min, and inoculate 3% Bacillus subtilis, Bacillus licheniformis, Bacillus megaterium, Bacillus natto, Bacillus coagulans when the temperature ...

[0028] Example 3

[0029] After the collected food waste is crushed and sorted to remove inorganic matter, add 0.03% high-temperature resistant amylase (40,000 U / g, purchased from Amano Enzyme Inc.) when cooking at 100°C and keep it warm for 1-2 hours, then pour out the grease Then, add 0.1% glucoamylase (100000U / g, purchased from Novozymes A / S) when the temperature drops to 50°C, and keep it warm for 2 hours; but when the temperature drops to 30°C, add 0.05% protease ( 100000U / g, purchased from Amano Enzyme Inc.) and 0.05% cellulase (100000U / g, purchased from Novozymes A / S) which accounts for the weight of kitchen waste, work together with kitchen waste liquid, and solid-liquid after 5 hours of heat preservation Separate and pump the liquid into the fermentation tank. The high temperature sterilization condition is 130℃, sterilization for 20min, and when the temperature is reduced to 35℃, 1% Bacillus subtilis, Bacillus licheniformis, Bacillus megaterium, Bacillus natto, Bacillus...

Abstract

The invention discloses a method for producing a microbial fertilizer or an inoculant for planting by using restaurant-kitchen garbage subjected to enzymolysis. The method comprises the following steps: crushing and sorting the collected restaurant-kitchen garbage to remove inorganic matters, adding high-temperature-resistant amylase during cooking and preserving heat, pouring out grease, adding glucoamylase in the cooling process and preserving heat, adding protease and cellulase and preserving heat, then performing solid-liquid separation on the restaurant-kitchen garbage subjected to enzymolysis, pumping liquid obtained by virtue of separation into a fermentation tank to perform high-temperature sterilization, inoculating microbial seed liquid for planting after cooling, fermenting for 24-48 hours at 25-37 DEG C, sub-packaging into each sealed container after fermentation to obtain the microbial fertilizer or the inoculant for liquid planting. The method disclosed by the invention aims to reduce the restaurant-kitchen garbage and perform high-valued application on the restaurant-kitchen garbage, and can be used for truly achieving restaurant-kitchen garbage treatment without secondary pollution; meanwhile, restaurant-kitchen garbage waste liquid with rich source and low cost is converted into a composite microbial fertilizer or the inoculant for planting with wide application prospects, and high-valued products are obtained; the method disclosed by the invention has particularly significant advantages.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a method for producing microbial fertilizer or bacterial agent for planting by enzymatically decomposing kitchen waste. Background technique [0002] Kitchen waste refers to the leftovers and waste edible oils and fats generated in food processing, catering services, unit meals and other activities other than residents' daily life, commonly known as swill, swill or slops. The generation of urban kitchen waste is extremely large, especially in large and medium-sized cities with developed economies, high living standards, and well-developed catering industries. According to relevant statistical data, the proportion of kitchen waste in several large cities in my country is about 37% in Beijing, 54% in Tianjin, 59% in Shanghai, 62% in Shenyang, 57% in Shenzhen and 57% in Guangzhou. Food waste has become a major pollution source of urban public environmental sanitation, the s...
