【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、UV_(254)和UV_(410)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 effects of temperature on ozone oxidation were studied by comparing the influent, coagulation-sedimentation effluent and micro-filtration water from the reclaimed water plant. The results show that there is an optimum temperature for the removal of chromaticity UV254 and UV_ _ (410) by ozone for three kinds of reclaimed water with different water quality. Under the condition of ozone dosage of 5 mg L ~ (-1) and residence time of 20 min, the better the raw water quality, the lower the optimum temperature of ozone oxidation treatment, and the better the sterilization efficiency of ozone regenerated water is when the ozone sterilization effect is below .24 鈩，
