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.

用Peroxone工艺去除饮用水源中的臭味和恶臭化合物:实验室和中试规模研究

摘要

某些蓝细菌和放线菌物种的代谢产物,例如土臭素和2-甲基异冰片醇(MIB),通常是地表水中的泥土和霉味的来源。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的系统中,都研究了用过氧化物处理工艺去除MIB的方法。使用2 mg / LO 3剂量的不同H 2 O 2:O 3比值来确定MIB去除的H 2 O 2:O 3最佳比例。最佳H 2实验室系统中的O 2:O 3比和接触时间分别确定为0.3和5分钟,而中试系统分别为0.5和15分钟。尽管两个系统的性能在相似的运行条件下都不同,但在特定于实验室和中试规模的最佳条件下,MIB去除效率可达到80%以上。
