Manufacturing process of fecal treatment equipment

The manufacturing process of fecal treatment equipment mainly includes the following steps:

Pre treatment: During the pre-treatment stage, it is necessary to adjust the moisture and carbon nitrogen ratio of feces. Usually, it is necessary to adjust the moisture content of feces to around 60% to ensure fermentation efficiency

High temperature aerobic fermentation: This stage includes rapid heating, high temperature stage, and cooling stage. Under the action of microorganisms, feces rapidly heat up to 50-65 ℃ within 8 hours, then remain at high temperature for 16 hours to decompose. Finally, oxygen demand is met through stirring and ventilation, and after fermentation is completed, the temperature is lowered to below 40 ℃

Automatic material collection: The materials in the fermentation chamber fall layer by layer under the action of gravity generated by the main shaft mixing, and are discharged through the discharge port

The process characteristics and advantages and disadvantages of different fecal treatment equipment:

Stacking processing equipment:

Advantages: fewer equipment, easy operation, and lower investment.

Vertical fermentation tank:

Advantages: High degree of mechanization, precise control of temperature and oxygen concentration, insulation not affected by climate.

Processing equipment for Yinuo Environment:

Advantages: Simple operation, high degree of automation, temperature and oxygen content control, insulation and energy saving not affected by climate, easy collection and control of odors, short fermentation cycle, small footprint, and low civil engineering investment
