| 摘 要： | 以再生水厂进水、混凝沉淀出水和微滤出水作为实验对象，对比研究了温度对臭氧氧化效果的影响。结果表明，对于3种不同水质的再生水而言，臭氧对色度、UV254和UV410的去除存在最佳温度。在臭氧投加量为5 mg·L-1及停留时间为20 min的条件下，原水水质越好，臭氧氧化处理的最佳温度越低，并且臭氧灭菌效果越好。24℃以下时臭氧再生水的灭菌率均为100%。随水温升高，臭氧灭菌效果稍有减弱，但都高于98%。

| Abstract: | The effect of water temperature on ozonation was investigated for reclaimed water influent, coagulation effluent, and microfiltration effluent. The source waters show differing optimal temperatures for ozonation removal of chromaticity, UV254, and UV410. With 5 mg·L-1 dose of ozone and 20 min hydraulic retention time, the optimal temperature decreases with the influent water quality increasing. The disinfection effect of ozonation increases with better water quality. At temperatures below 24℃, ozonation achieves 100% disinfection. As water temperature increases, disinfection effect declines slightly, but remains above 98%. |
