1. Experimental purpose:
Anaerobic 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 a series of obvious advantages such as high organic load, low sludge production, and low energy consumption. Upflow anaerobic sludge bed (UASB) is a m*n structure of anaerobic biological treatment. It integrates anaerobic biological reaction and sedimentation separation. It has high organic load and removal efficiency and does not require stirring equipment. This model is a teaching experimental equipment for upflow anaerobic sludge bed. Through this experiment, we hope to achieve the following goals:
1. Understand the internal structure of UASB;
2. Master the startup method of UASB and the formation mechanism of granular sludge;
3. Conduct dynamic tests on a cert*n sewage to determine the process parameters and the water quality of the treated water.
