摘　　要：将脊髓灰质炎病毒（ Ｐｏｌｉｏ Ｖ） 及不同消毒剂投加到模拟水样中，按不同接触时间１ ，３ ，１０ ，３０ ｍｉｎ 取样，空斑定量． 当模拟水有机质含量 Ｃ Ｏ Ｄ 为２０ ｍｇ／ Ｌ，病毒浓度ｎ（ Ｐ Ｆ Ｕ） ≈１ ×１０５ ｍ Ｌ－ １ 时，分别投加氯制剂有效氯ρ（ Ｃｌ）１６ ｍｇ／ Ｌ，接触３０ ｍｉｎ ；ρ（ Ｃｌ Ｏ２） ＝ ８ ．０ ｍｇ／ Ｌ，３０ ｍｉｎ ； Ｃｌ＋ Ｃｌ Ｏ２ 联合消毒剂（５ ．０ ＋ ５ ．０） ｍｇ／ Ｌ，３０ ｍｉｎ ；ρ（ Ｏ３） ＝ １ ．２２ ｍｇ／ Ｌ，１０ ｍｉｎ 时；可使病毒彻底灭活． 它们使 Ｐｏｌｉｏ Ｖ 达到９９ ．９９ ％ 灭活的浓度时间乘积（ ρ×ｔ） 值分别是６６２ ．５ ，１２９ ．５ ，２００ ．０ 和３ ．２ ｍｇ Ｌ－ １ ｍｉｎ ． 消毒效果（ 顺序） 为 Ｏ３ ＞ Ｃｌ Ｏ２ ＞ Ｃｌ＋ Ｃｌ Ｏ２ ＞ Ｃｌ． 联合消毒灭活 Ｐｏｌｉｏ Ｖ 的效果为 Ｃｌ 的３ ．３ 倍，表明将 Ｃｌ 与 Ｃｌ Ｏ２ 联合应用具有协同效应。Poliovirus I in the simulated water made up of distilled water and fulvic acid was disinfected by desired concentrations of various disinfectants. Aliquots of water volume were withdrawn at 1, 3, 10 and 30 minutes and quantified with a plaque assay. When COD concentration was 20 mg/L and initial virus n (PFU)≈1×10 5 mL -1 in water, the exposure of poliovirus particles to 16.0 mg/L of chlorine, 8.0 mg/L of chlorine dioxide, and a combination of equal doses of 5.0 mg/L chlorine and 5.0 mg/L chlorine dioxide for 30 minutes respectively and to 1.22 mg/L of ozone for 10 minutes could result in complete inactivation of these viruses. The values of ρ × t for 99.99 percent inactivation of poliovirus by the above mentioned disinfectants were 662.5, 129.5, 200.0 and 3.2 mg/L min, respectively. Four disinfectants had the following order of inactivation of the virus: O 3>ClO 2>Cl+ClO 2>Cl. On the basis of ρ × t values, single chlorine was less effective than the combination of chlorine and chlorine dioxide by factor of about 3.3 fold for poliovirus, indicating that the combined disinfectant which could also reduce by products formation was superior to the single chlorine widely used in water disinfection.
