过氧化氢与臭氧联合消毒对泳池水灭菌效果的影响
|
摘要
为了研究过氧化氢与臭氧联合的消毒方式对泳池水的消毒效果及作用机理,采用不同浓度配比的过氧化氢与臭氧联合消毒方式对人工配置的较高负荷的泳池水进行消毒,并分析不同浓度配比的过氧化氢与臭氧联合消毒方式对水中氧化还原电位、大肠杆菌、细菌总数等指标的影响及持续消毒能力。结果表明:水温保持25℃,消毒接触时间2 h内,最佳的联合消毒配比宜为50 mg/L H_2O_2+0. 20 mg/L O_3,相对于50 mg/L H_2O_2单独消毒,氧化还原电位相对提高24. 46%,大肠群菌和细菌总数的灭菌率分别提高16. 08%、11. 34%。6 h后细菌总数和大肠群菌均无法检出,3项指标均满足标准要求。可见通过降低H_2O_2浓度同时投加少量O_3可有效提高并维持相对稳定的消毒效果。
In order to research on the effect and mechanism of the disinfection combined hydrogen peroxide with ozone on swimming pool water,hydrogen peroxide and ozone at different concentration ratios were used to sterilize the artificial pool water with high load to analyze the effects of hydrogen peroxide combined with ozone at different concentration ratio on the water quality indexes like ORP,Escherichia coli,the total bacteria and the ability of continuous disinfection. The results show that when the water temperature is kept at 25 ℃ and the contact time for disinfection is within 2 hours,the best concentration ratio of combined disinfection is 50 mg/L H_2O_2 combining with0. 20 mg/L O_3,and the ORP increases by 24. 46%,while the sterilizing rate of Escherichia coli and the total bacteria are respectively increased by 16. 08% and 11. 34% relative to only using 50 mg/L H_2O_2 for disinfection. After 6 hours,the total number of bacteria and Escherichia coli both can not be detected,and the three indexes all meet the requirements of the standard. It is concluded that reducing the concentration of H_2O_2 and adding a small amount of O_3 can effectively enhance and maintain a relatively stable disinfection effect.
