The main characteristics of anaerobic digestion technology are briefly described.

Anaerobic digestion technology mainly has the following characteristics:

(1) has the characteristics of controllable process, fast degradation and closed production process;

(2) the energy utilization effect is good, and the low-grade bioenergy in the waste organic matter can be converted into high-grade biogas which can be directly utilized;

(3) The operation is simple, compared with aerobic treatment, anaerobic digestion does not need ventilation power, the facilities are simple, and the operation cost is low, which is an energy-saving treatment method;

(4) The product can be reused and is suitable for treating high-concentration organic wastewater and wastes. After anaerobic digestion, the garbage is basically stable and can be used as agricultural fertilizer, feed or compost raw materials;

(5) The growth rate of anaerobic microorganisms is slow, the treatment efficiency of conventional methods is low, and the equipment volume is large;

(6) Odor gases such as H2S will be produced in the anaerobic process.
