Abstract:

The test of a flat plate film SMBR device in the coking plant is described. The result shows that the coking wastewater treatment with the flat plate file SMBR device is characterized by many advantages, such as strong impact resistance capability, high removal efficiency of ammonia nitrogen and COD, stable sludge concentration, less generated sludge amount, film strong resistance capability to pollution, long cleaning interval, stable discharged water index and so on. The externally discharged water can be up to the national class I standard.
