Problems solved by technology

[0004] Food waste mixed with domestic waste and entering the landfill not only occupies a large amount of storage capacity, but also produces a large number of high-concentration organic pollutants in the leachate, which greatly increases the load and difficulty of landfill leachate treatment; the moisture content of food waste High, incinerated together with domestic waste, while reducing the calorific value of waste, it will also produce dioxins due to insufficient combustion, causing secondary pollution to the environment. In addition, the incineration and landfill treatment of kitchen waste will also cause waste of organic matter

Embodiment 1

[0017] Take 30 parts of Bacillus halotolerant, 30 parts of Bacillus licheniformis, 30 parts of Bacillus natto, 10 parts of Azotobacter torus, and 10 parts of Pichia pastoris.

[0018] Specific culture method: Bacillus halotolerant, Bacillus licheniformis, Bacillus natto, and Azotobacter torus were cultured in LB based on shaking at 30°C for 18 hours. Pichia pastoris was cultured with YPD based on shaking at 30°C for 36 hours.

[0019] Specific solidification method: use straw powder as the immobilization carrier, and attach bacteria to the carrier to form a solid bacterial agent. The ratio of compound bacterial liquid: solid carrier is 1:5. The bacterial liquid and straw powder are put into the appropriate mixing device in proportion for immobilization treatment, and it can be completed after 48 hours. The concentration of effective bacteria is required to reach 1.5~9.9×10 13 CFU / g.

[0020] Specific treatment methods:

[0021] Put the compounded bacterial agent and organ...

Embodiment 2

[0025] Take 35 parts of Bacillus halotolerant, 30 parts of Bacillus licheniformis, 35 parts of Bacillus natto, 10 parts of Azotobacter torus, and 5 parts of Pichia pastoris.

[0026] Specific culture method: Bacillus halotolerant, Bacillus licheniformis, Bacillus natto, and Azotobacter torus were cultured in LB based on shaking at 30°C for 18 hours. Pichia pastoris was cultured with YPD based on shaking at 30°C for 36 hours.

[0027] 1. Specific solidification method: After the fermentation of the bacterial liquid is completed, filter the bacterial liquid, discard half of the filtrate, use straw powder as the immobilized carrier, and attach the bacteria to the carrier to form a solid bacterial agent. The ratio of composite bacteria liquid: solid carrier is 1:5. Put the bacteria liquid and straw powder in proportion to the appropriate mixing device for immobilization treatment, which can be completed after 24 hours. The concentration of effective bacteria is required to reach...

Abstract

The invention discloses a bacterial agent used for processing organic garbage. The bacterial agent comprises 30-60 parts of salt-tolerant halobacillus halophilus, 30-60 parts of bacillus licheniformis, 30-60 parts of bacillus natto, 10-40 parts of azotobacter chroococcum and 5-15 parts of pichia pastoris. The invention also discloses a preparation method and a utilization method of the above bacterial agent. The bacterial agent disclosed by the invention is suitable for high-temperature, intermediate-temperate and low-temperature aerobic fermentation processes, and can effectively process organic rotten garbage to realize harmlessness, minimization and reclamation. Meanwhile, a processing process is simple and effective, a fermentation period is short, a processing cost is low, and the bacterial agent is friendly to the environment and is free from secondary pollution.

Description

technical field [0001] The invention relates to the technical field of organic waste treatment, in particular to a bacterial agent for treating organic waste, a preparation method and a use method thereof. Background technique [0002] With the continuous growth of the global population base and the improvement of people's living standards, the discharge of food waste is increasing day by day. On the one hand, a large amount of food waste has brought serious pollution, on the other hand, it has caused huge waste, which has brought great troubles to all countries. If these food wastes rich in biomass can be further utilized as resources, it will not only be beneficial to environmental protection, but also increase the utilization of renewable resources by human beings, which is in line with the development direction of sustainable development and circular economy. [0003] On December 24, 2012, the Ministry of Housing and Urban-Rural Development of the People's Republic of C...
