Embodiment 1

[0012] Embodiment 1, this technique is made up of following steps:

[0013] (1) Separating the collected kitchen swill from solid impurities, and removing the oil layer on the surface of the swill; then performing centrifugal dehydration on the swill, crushing the dehydrated swill sediment, and setting aside;

[0014] (2) According to the percentage by weight, take 45-50% of the swill sediment prepared in the step (1), prepare with 5-8% of corn flour and 42-50% of tap water, and the sum of the percentages of each component is 100%. Then put it in a pressure cooker, keep the pressure at 0.048-0.110MPa, temperature 111-122°C, and after 1-1.2 hours, turn on the pressure cooker to obtain the base liquid of the bio-promoter, and set it aside; (3) to be prepared in step (2) The temperature of the good bio-growth-promoting agent base solution is lowered to 5-10°C, add 3-3.5% of pancreatic digestive enzyme solution, keep the temperature at 45-50°C, stir evenly, and react for 2-2.5h to...

Embodiment 2、1

[0018] Embodiment 2, 1. Go to the sanitation station to obtain swill, first separate the solid impurities in the swill in the solid impurity separation equipment, use the principle of isobiter to absorb the oil layer on the surface of the swill, and then pass the swill without solid impurities into The solid-liquid separator is used for centrifugal dehydration, and then the dehydrated sediment is crushed and crushed with a pulverizer; 2. The ratio of 45% of the treated swill, 5% of corn flour, and 50% of tap water is prepared and placed in the pot .

[0019] 3. Increase the pressure to 0.048MPa, the temperature is 111°C, turn off the switch about 1 hour after the pressure is reached, and turn on the pressure cooker after 30 minutes of heat preservation to obtain the base liquid of the bio-growth accelerator, and set it aside;

[0020] 4. Preparation of pancreatic digestive enzyme liquid, wherein the proportion of pancreatic digestive enzyme liquid is: pancreatic digestive enzy...

Embodiment 3、1

[0026] Embodiment 3, 1. Go to the sanitation station to obtain swill, first separate the solid impurities in the swill in the solid impurity separation equipment, use the principle of isobiter to absorb the oil layer on the surface of the swill, and then pass the swill without solid impurities into The solid-liquid separator is used for centrifugal dehydration, and then the dehydrated sediment is crushed and crushed with a pulverizer; 2. The ratio of 50% of the treated swill, 8% of corn flour, and 42% of tap water is prepared and placed in the pot .

[0027] 3. Increase the pressure to 0.110MPa, the temperature is 122°C, turn off the switch about 1.2 hours after the pressure reaches, and turn on the pressure cooker after 40 minutes of heat preservation to obtain the base liquid of the bio-promoter, and set it aside;

[0028] 4. Preparation of pancreatic digestive enzyme liquid, wherein the proportion of pancreatic digestive enzyme liquid is: pancreatic digestive enzyme 8%, wat...

Abstract

The invention belongs to the technical field of kitchen waste swill innocent treatment, and particularly relates to a process for preparing a bio-stimulant by utilizing swill. The process comprises the following steps: (1) separating solid impurities of collected kitchen swill, and removing the oil layer on the surface of the swill; centrifugally dehydrating the swill, and grinding the dehydrated swill precipitate for later use; (2) preparing a basic liquid of bio-stimulant for later use; (3) preparing a stock solution of the bio-stimulant; and (4) regulating the pH value of the prepared stock solution of the bio-stimulant in the step (3) to 5.0-5.5; and concentrating the stock solution of the bio-stimulant to 55-60 times to obtain the bio-stimulant. The process is mainly used in the field of wastewater treatment.

Description

technical field [0001] The invention belongs to the technical field of harmless treatment of kitchen waste swill, and in particular relates to a process for preparing biological growth-promoting agents from swill. Background technique [0002] Swill refers to leachate or diluent of leftover soup leftovers discarded in canteens, restaurants, etc. It is mainly composed of water and dry matter, of which water accounts for about 80% and dry matter accounts for about 20%. Among them, dry matter mainly includes carbohydrates, animal protein, fat, vegetable oil, napkins, tableware, plastic bags, etc.; it is rich in amino acids, fat and protein. Protein accounts for about 26% in dry matter, and digestible energy is about 3.2kcal / kg. On the one hand, swill has a high content of organic substances and less toxic substances; but on the other hand, swill is perishable and degenerates, giving off stench and seriously polluting the environment. [0003] Food waste is a breeding ground f...
