Embodiment 1

[0040] The present embodiment provides a kind of composite bacterial agent comprising: white rake tooth bacteria, rumen microorganism, Bacillus subtilis, Bacillus cereus, Bacillus stearothermophilus, Klebsiella oxytoca, Bacillus licheniformis and Aspergillus niger , and the dry basis mass ratio of each bacteria is: 4:4.5:6:6:10:4:6:4.5. The dry matter of each bacterium of the composite bacterial agent of the present invention can be obtained through existing conventional processing methods, for example, carry out vacuum low-temperature concentration to each bacterium culture solution, and then freeze-dry to make bacterium dry powder, and then mix each according to the mass ratio. Bacteria dry powder, the dry powder mixture of the composite bacterial agent of this embodiment is prepared, and then packaged and stored for later use, the solid mixture takes up little space, and is convenient for dormant storage of each bacterium, prolonging the storage time.

Embodiment 2

[0042] This embodiment provides a method for fermenting and treating kitchen waste using the composite bacterial agent provided in Embodiment 1, including the following stages:

[0043] Bacterial cell activation stage: add the dry powder mixture of 1 kg of the composite bacterial agent prepared in Example 1 into the processing equipment, add 200 ml of water, adjust the temperature to 35 degrees, and activate for 6 hours;

[0044] Fermentation treatment stage of food waste: Then add food waste to the processing equipment, mix it evenly with the activated compound bacteria agent, and carry out fermentation and decomposition. The ratio of compound bacteria agent to food waste can be adjusted according to actual needs , the larger the proportion of the composite bacterial agent, the faster the speed of decomposing the garbage. In this embodiment, 2 kg of kitchen waste is put into a batch; For 16 hours, the activated bacteria rapidly grow and increase in value through the nutrients...

Embodiment 3

[0049] Such as Figure 1-7 As shown, this embodiment provides a treatment device, which provides a suitable reaction environment for the composite microbial agent and kitchen waste, and effectively improves the treatment efficiency of kitchen waste.

[0050] The processing equipment of the present embodiment comprises a cabinet 1, and the upper part of the cabinet 1 is connected with a loam cake 2 that is convenient to open and close; the inside of the cabinet is provided with a stirring device, a heating device and a driving device 4, and the stirring device includes a mixing bucket 31, and a stirring device is provided inside it. Shaft 33, stirring blade 32 is arranged on the circumference of stirring shaft 33, and stirring barrel 31 is used to accommodate composite bacteria agent and kitchen waste; heating device can be arranged on the inside and / or outer wall of stirring device to heat stirring device, drive The device 4 is transmission-connected with the stirring shaft 33...

Abstract

The invention provides a composite bacterial agent and a method for treating kitchen waste through the composite bacterial agent and relates to the technical field of kitchen waste treatment. The technical problem of low degradation efficiency for the kitchen waste in the prior art is solved. The composite bacterial agent comprises IrPex Cacteus, rumen microorganisms, bacillus subtilis, bacillus cereus, bacillus stearothermophilus, klebsiella oxytoca, bacillus licheniformis and aspergillus niger. By means of the composite bacterial agent and a treatment device and method, 90% or above of organic waste in the kitchen waste can be degraded, and the treatment efficiency is high.

Description

technical field [0001] The invention relates to the technical field of kitchen waste treatment, in particular to a composite microbial agent and a method for treating kitchen waste. Background technique [0002] With the improvement of human material living standards, domestic waste has become a serious social problem, and due to the large amount of food consumption and bad eating habits, kitchen waste accounts for the largest proportion of domestic waste. [0003] At present, food waste is usually treated according to the treatment methods of ordinary solid waste, such as landfill and incineration. At present, there are the following problems in the utilization of food waste treatment resources in my country: there is no perfect management system for the harmless treatment and resource utilization of food waste; the built resource facilities cannot operate at full capacity; there is a lack of thorough harmless treatment and a high degree of resource utilization Practical te...
