The performance of combined process of visible light photocatalysis and three-phase biofluidized bed in treatment of the 4-chlorophenol wastewater was studied.

Test study on three-phase biological fluidized bed treating wastewater containing phenol in refinery;

Hydraulic Residence Time Distributions(RTDs) in an inner loop three-phase biological fluidized bed reactor were measured under different flow regimes using pulse stimulus-response technique method.

A determination method on k_La in three-phase biological fluidized bedhad founded firstly according to the experiment in this paper.

And simulated tests using three phase biological fluidized bed to degrade artificial phenol containing wastewater and practical phenol containing wastewater which was produced in the refinery of Yanshan Petrochemicd Company are conducted.

The formula of expansion characteristic in the three phase biological fluidized bed has been founded in this study.

Two types of inner loop three phase biological fluidized bed pilot reactors are introduced,and they are used to treat domestic wastewater.

A combined process of hydrolytic acidification,inner loop three phase biological fluidized bed,anoxic/oxic(A/O)and valveless filter applied in the treatment and reuse of the urethane elastic fibre industrial wastewater is presented in this paper.
