摘　　要：为了提高生化单元入水可生化性,采用紫外-芬顿法预处理固定床气化废水,通过单因素试验及正交试验法分析了H2O2投加量、FeSO4投加量及紫外灯功率对预处理效果的影响。结果表明:3种因素对COD去除率及可生化性影响都较为显著,最佳工艺参数为H2O2投加量22 mL/L,FeSO 4投加量2.7 g/L、紫外灯功率为2.5 kW;在最佳参数条件下进行72 h连续试验,COD去除率为50%~54%,出水可生化性为0.4~0.43,处理效果稳定。In order to improve the biodegradability of the influent into the biochemical unit,UV Fenton oxidation process was applied in the pre-treatment of fixed bed gasification wastewater.The influences of H2O2 dosage,FeSO4 dosage and UV lamp power on pretreatment effect was analyzed by single-factor test and orthogonal test.The results showed that all these three factors influenced the COD removal rate and biodegradability significantly.The optimal process parameters were H2O2 dosage=22 mL/L,FeSO 4 dosage=2.7 g/L and UV lamp power 2.5 kW.72 hours continuous test with the optimal process parameters stably resulted in a COD removal rate of 50%~54%and effluent biodegradability of 0.4~0.43.
