Embodiment 1

[0018] A technological process for treating sick and dead animal sewage, the treatment process comprising the following steps:

[0019] (1) Pretreatment separation process

[0020] Cool the sewage in the sewage tank of sick and dead animals to 35°C, seal and heat-preserve the deep water anaerobic stirring for 24 hours, the sewage is separated by a tube-bundle centrifuge, and the solid phase is returned to the crusher; the liquid phase is kept at 35°C through a microflow reactor Anaerobic reaction for 90 minutes, the sewage is centrifuged by a three-phase horizontal centrifuge, and the solid phase is returned to the crusher; after the liquid phase and activated microorganisms are mixed evenly, the aerobic reaction temperature is controlled at 40°C for 56 hours of biochemical reaction, and the sewage is passed through three After centrifugation in a horizontal centrifuge, the solid phase is returned to the temporary storage tank for activated microorganisms, and the liquid phase...

Embodiment 2

[0026] A technological process for treating sick and dead animal sewage, the treatment process comprising the following steps:
