Abstract:

The experimental research and industrial practice on deep treatment of coking effluent with microwave technology was introduced in the paper. The test showed: the comprehensive effect of treatment of start microwave flow is better than stop microwave flow, there exists non-thermal effect in deep treatment of coking effluent process of microwave technology with microwave oven, namely existence of two functions (instantaneous and continuous functionsp）,  the quality index of effluent from system is better than first class standard given in GB 8978—1996,  the quality of coking effluent after treatment meets the quality requirement of return water.  The microwave technology for treatment of waste water is the effective way of reducing fresh water consumption per ton of coke.
