为探讨非吸附性稳态二氧化氯固体消毒剂(文华206消毒剂)对饮水的消毒效果,用双盲法调查了文华206消毒剂对深井水的消毒效果。结果表明,文华206消毒剂1 mg/L作用30 min后对水质有明显改善,水的色度从作用前的20度降至10度,铁、锰、细菌总数、大肠菌群分别从0.35 mg/L、0.11 mg/L、1 250个/L、46个/L降至0,但氯化物含量略有增高。文华206消毒剂5 mg/L作用30 min后,与经超滤除菌的深井水对照相比,口感好的分别占24%和42%,口感差的百分率均为0,有明显异味的分别占8%和2%。结论:文华206消毒剂1 mg/L消毒30 min后对水质有明显改善,且不影响口感,可作为部队野外作业、外出执勤、执行紧急任务、部队演练和作战时的饮水消毒。
In order to explore the disinfection effect of non-adsorbed steady-state chlorine dioxide solid disinfectant (Wenhua 206 disinfectant) on drinking water, the disinfection effect of Wenhua 206 disinfectant on deep well water was investigated by double-blind method. The results showed that the water quality of Wenhua 206 disinfectant was significantly improved after treated with 1 mg / L for 30 min, the chroma of water decreased from 20 degrees to 10 degrees before the effect, the total iron, manganese, bacteria and coliform were from 0.35 mg / L, 0.11 mg / L, 1 250 / L, 46 / L down to 0, but the chloride content increased slightly. Wenhua 206 disinfectant 5 mg / L for 30 min, compared with the ultrafiltration of deep well water control, the good taste accounted for 24% and 42% respectively, the percentage of poor mouthfeel was 0, with significant odor Accounting for 8% and 2% respectively. Conclusion: Wenhua 206 disinfectant disinfected at 1 mg / L for 30 min had obvious improvement on water quality without affecting the mouthfeel. It could be used as field work of the troops to go out on duty, perform emergency tasks, exercise troops and disinfect water during combat.
