针对农村生活饮用水存在细菌二次污染的问题,研究了3种载银抗菌吸附材料对于农村生活饮用水的杀菌效果,同时优化了应用条件。结果表明,较之于载银电气石和载银硅藻土,载银沸石在达到相同杀菌效果的前提下,可以更多的节约成本,更适合应用于农村生活饮用水的净化.当载银量为64.56 mg/g的沸石投加量为0.06 g(每100 m L水)时,杀菌率高达94.52%。用其处理黑龙江某地生活饮水,其杀菌率可达85.33%,饮用水处理后的微生物指标达到国家饮用水标准(GB 5749-2006)。
Aiming at the secondary bacterial contamination in rural drinking water, the sterilization effects of three silver-loaded antimicrobial adsorbent on drinking water in rural areas were studied, and the application conditions were optimized. The results show that silver-loaded zeolite can save more cost and is more suitable for purification of drinking water in rural areas than silver-loaded tourmaline and silver-loaded diatomaceous earth. When the zeolite dosage was 64 mg / g and the dosage of zeolite was 0.06 g (per 100 m L of water), the sterilization rate was as high as 94.52%. With its treatment of drinking water in Heilongjiang somewhere, the sterilization rate of up to 85.33%, microbial indicators after drinking water treatment to meet the national drinking water standards (GB 5749-2006).
