ABSTRACT

Metabolites of some cyanobacteria and actinomycete species such as geosmin and 2-methylisoborneol (MIB) are generally the sources of earthy and musty odor in surface waters. Peroxone process, that is a combination of ozone (O3) and hydrogen peroxide (H2O2), has the potential to effectively remove these compounds. In this study, the removal of MIB with the peroxone process was investigated at both laboratory- and pilot-scale systems. Different H2O2:O3 ratios with 2 mg/L O3 dosage were applied for determining the optimum ratio of H2O2:O3 for MIB removal. The optimum H2O2:O3 ratio and contact time in the laboratory system were determined as 0.3 and 5 min, respectively, whereas they were 0.5 and 15 min for the pilot system, respectively. Although the performances of both systems were different at similar operating conditions, MIB removal efficiencies over 80% were achieved at the optimum conditions specific to laboratory and pilot scale.

通过过氧酮工艺去除饮用水源中引起味道和气味的化合物:实验室和中试规模研究

摘要

一些蓝藻和放线菌的代谢物,如土臭素和 2-甲基异冰片 (MIB),通常是地表水中泥土和霉味的来源。Peroxone 工艺,即臭氧 (O 3 ) 和过氧化氢 (H 2 O 2 ) 的组合,具有有效去除这些化合物的潜力。在这项研究中,在实验室和中试规模系统中研究了用过氧酮工艺去除 MIB。应用具有2mg/LO 3剂量的不同H 2 O 2 :O 3比率来确定用于去除MIB的H 2 O 2 :O 3的最佳比率。最佳 H 2实验室系统中的O 2 :O 3比率和接触时间分别确定为 0.3 和 5 分钟,而中试系统的分别为 0.5 和 15 分钟。尽管两种系统在类似操作条件下的性能不同,但在实验室和中试规模特定的最佳条件下实现了超过 80% 的 MIB 去除效率。
