Embodiment Construction

[0020] Embodiment of the present invention is described below in conjunction with accompanying drawing, embodiment does not constitute limitation of the present invention:

[0021] oxygen concentration

[0022] With the progress of aerobic fermentation of domestic waste, the activities of microorganisms consume oxygen all the time. In order to ensure the quality of aerobic fermentation, the oxygen content should be supplemented in time according to the changes of various indicators in the fermentation materials during fermentation.

[0023] Appropriate range: During the aerobic fermentation process of organic waste, the appropriate oxygen concentration is 14% to 17%. If it is too low (<10%), the lack of oxygen will inhibit the growth of aerobic bacteria and stop aerobic fermentation; otherwise, if the oxygen concentration is higher than 20%, the air volume should be reduced until the oxygen concentration is suitable.

[0024] Adjustment method:

[0025] (1) During the stirri...

Abstract

The invention relates to the field of fermentation, and particularly relates to a control method for organic waste fermentation. The method comprises oxygen content control, temperature control, pH value control, humidity control, organic matter content control, and carbon nitrogen ratio control; six factors of affecting organic waste fermentation are required to be monitored in real time in an aerobic fermentation process of domestic waste, for example, determined data of the organic matter content, the humidity, the carbon nitrogen ratio and the pH value when the organic waste enters a reservoir, and change data of the oxygen concentration, the C / N ratio, the organic matter content, the humidity, the temperature and the pH value in the fermentation process. The factor is required to be timely adjusted if one factor deviates from the appropriate range, so that the biological degradation process of the organic waste can be smoothly carried out; the method adjusts measures to local conditions, adjustment is carried out by adopting the organic waste, a foreign intervention material is reduced, and the method is low in cost and good in regulation effect.

Description

technical field [0001] The invention relates to the field of fermentation, in particular to a method for controlling the fermentation of organic waste. Background technique [0002] Organic matter in life is organic matter and nutrient salts. Such substances include cellulose, furfural, and grease discharged from industry, feces, detergents, and food residues in domestic sewage, and waste liquid from chemical fertilizers. Divided into 4 types of organic pollutants: volatile, refractory, and persistent, which cause pollution and are difficult to be effectively used. However, it is not worthwhile to use special equipment for fermentation and fermentation. A fermentation control with high raw material utilization is needed. method. Contents of the invention [0003] Purpose of the invention: In order to provide an environmentally friendly method for controlling the fermentation of organic waste, see the multiple substantial technical effects in the specific implementation p...
