本幻灯片概述了一项关于在有无臭氧的情况下使用生物活性炭（BAC）过滤器去除味道和气味（T&O）并改善水质的研究的中试结果。试点目标是评估以下措施的有效性: 中试预处理装置去除颗粒物， 有机物和任何导致T&O的化合物； BAC过滤器，用于在存在和 没有臭氧；和 pH值降低和添加过氧化氢对反应的影响 臭氧氧化去除T&O。 观察结果包括: G/S过滤器配置不会对颗粒物造成任何损害 移动 天然有机物（NOM）的G/S、A/S和过滤性能相似； G/S为生物附着/生长提供了更好的座位，并可能 通过生物降解提高NOM去除率； 臭氧在一定条件下可使贾第虫失活0.5 log 剂量约为2.5 mg/L（目标O3/TOC比率为0.5）； 在臭氧剂量为2.5-2.7 mg/L（O3/TOC比率为0.5）时 提供高达75%的MIB去除率和45%的TTHMs减少率； 以H2O2/O3的比例添加H2O2可能不会提高MIB的去除率；生物GAC（G/S）过滤器可提供高达30-40%的MIB 通过生物氧化去除； 生物无烟煤过滤器（A/S）显示MIB去除率为10-18% 通过生物氧化； 由澄清-臭氧氧化-GAC组成的工艺序列 生物过滤器有望提供足够的颗粒物、NOM和MIB （90%或以上）移除； 由澄清组成的过程序列- GAC生物过滤器（无 臭氧）、NOM、MIB的去除和TTHM的减少预计将得到改善 与包括臭氧氧化的方法相比更低；和 该工艺序列中的MIB去除预计将在30到40分钟内完成 百分比范围。额外的MIB清除需要通过 加入PAC。包括数字。

This slide presentation outlines the pilot scale findings of a study on removing taste and odor (T&O) and improving water quality with biologically active carbon (BAC) filters in the presence and absence of ozone. Pilot objectives were to evaluate the effectiveness of: pilot pretreatment unit in removing particulate, organics and any T&O causing compounds; BAC filters for removing T&O in presence and absence of ozone; and, impact of pH depression and peroxide addition on ozonation for removing T&O. Observations include: G/S filter configuration will not result in any compromise in particle removal; G/S and and A/S and filter performances are similar for natural organic matter (NOM); G/S provides better seat for biological attachment/growth and may improve NOM removal by biological degradation; ozone can provide 0.5-log inactivation of Giardia at an applied dose of approximately 2.5 mg/L (target a O3/TOC ratio of 0.5); at an ozone dose of 2.5-2.7 mg/L (O3/TOC ratio of 0.5) will provide up to 75 percent MIB removal and 45% TTHMs reduction; adding H2O2 at a H2O2/O3 ratio may not enhance MIB removal; biological GAC (G/S) filters may provide up to 30-40 percent MIB removal through biological oxidation; biological Anthracite filters (A/S) show 10-18 percent MIB removal through biological oxidation; a process train consisting of clarification - ozonation - GAC biofilters is expected to provide adequate particle, NOM and MIB (90% or more) removal; a process train consisting of clarification - GAC biofilters (without ozone), NOM, MIB removal and TTHM reduction is expected to be lower compared to the one including ozonation; and, MIB removal in this process train is expected to be in the 30 to 40 percent range. Additional MIB removal need to be achieved with the addition of PAC. Includes figures.
