1. Experimental purpose:

Aerobic biological treatment technology is not only used for organic sludge and high concentration organic wastewater, but also can treat low concentration sewage. Compared with aerobic biological treatment technology, anaerobic biological treatment has high organic load, low sludge yield, energy consumption, energy consumption A series of obvious advantages. The lift -type anaerobic sludge bed (UASB) is a major structure of anaerobic biological treatment. It integrates anaerobic biological reactions and sedimentation separation. Organic load and removal efficiency are high, and no mixing equipment is required. This model is a teaching experimental equipment for lift -type anaerobic sludge beds. Through the hope of this experiment, the following goals are achieved:

1. Understand the internal structure of UASB;
