Abstract:

The technology of biochemical - air floats - filtration - disinfection is used to process the salt -escaped waste water and the methanol wastewater. After the sewage is processed, all the indexes of the water quality surpass the nation’s standard that is stipulated in recycling sewage. Moreover, the water may also be reused as the cooling water. The project is considered cost effective.

Key words: methanol wastewater, biological fluidized bed, flocculation, gas floats
