摘　　要：以精制棉废水为研究对象,采用超声(US)、光化学氧化(UV/H2O2)和超声-光化学氧化(US+UV/H2O2)法处理精制棉废水,探讨了不同方法对精制棉废水的COD及色度的去除效果及其影响因素。结果表明,采用UV/H2O2+US联合处理废水时,在pH值为4,H2O2投加量0.8mL/L,超声功率为75W,紫外波长为365nm的条件下,反应40min时,COD去除率为37.83%,色度去除率为60%。COD去除率比单独使用US或UV处理时有较大的提高,但与采用UV/H2O2处理的结果相比提高不明显。UItrosonie（US）, Ultroviolet（UV）/H2O2 and US ＋ UV/H2O2 process were used to treat refined cotton wastewarter. Factors affecting the removal of COD and chroma with the different methods were discussed. The results show that for the UV/Hz 02 ＋US joint processing, under the condition of pH value of 4, H2O2 dosage as 0.8 mL/L, ultrasonic power as 75 W, ultraviolet wavelength as 365 nm and reaction time as 40 min, the removal rate of COD and chroma is 37.83% and 60%, respectively. The removal rate of COD under this condition is significantly higher than that of using US or UV technique alone, but no obvious degradation increase was found compared with that of using UV/H2O2 technique.
