Aerobic biological treatment training device

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. A m--n structure of anaerobic biological treatment, which integrates anaerobic biological reactions and sedimentation, is separated, with high organic load and removal efficiency, and no mixing equipment is required. This model is a teaching experimental equipment for anaerobic reactor. Through the hope of this experiment, the following goals are achieved:

1. Understand the internal structure of anaerobic;

2. Master the method of starting the anaerobic, the formation of granular sludge;

3. Dynamic tests on a cert--n sewage to determine process parameters and process water quality.

Second, the purpose of membrane reaction experiments:

Film reactor sewage treatment device is a test device for integrated membrane biological reactors. The membrane bioreactor is a new sewage treatment process produced by the organic combination of membrane technology sewage biological treatment technology. Its production and development are the inevitable results of these two types of knowledge applications and development. Film technology and sewage biological treatment technology disciplines cross, combine, and open up new areas of sewage treatment technology research and application. Through the hope of this experiment, the following goals are achieved:

1. Understand the structure and working principle of membrane bioreactor;

2. Master the design and operation of the membrane biological reactor;

3. Merring the effectiveness of the membrane biological reactor to handle various sewage;

4. Explore the method of preventing membrane pollution and the method of membrane cleaning.
