三氯异氰尿酸是一种固体的、稳定的、有机氯制剂(Trichloroisoeyanuric acid,TCCA);但应用在饮水消毒方面至今尚未见到系统的报道。为了探讨TCCA对饮水消毒的效果和应用TCCA消毒饮用水,做了以下试验。一、实验室TCCA对饮水消毒的效果观察试验选用埃希氏大肠杆菌,用比浊法计算菌液含菌数,实验水体选用上海闸北自来水厂水,煮沸灭菌放冷备用。在27个组合组中,剂量1.4～3.4毫克/升,时间10～30分钟,水温5～30℃,pH5～9,除了水温5℃和PH9的7、19号组合组的除菌率只达99,94％外,其余的25个组合组的除菌率都达到了99.99％。
Trichloroisocyanuric acid is a solid, stable, organochlorine (TCCA) preparation; however, there is no systematic report on its application in drinking water disinfection. In order to explore the effect of TCCA on drinking water disinfection and the application of TCCA to disinfect drinking water, the following experiment was done. First, the laboratory TCCA effect on drinking water disinfection Ehs Escherichia coli test, turbidimetric method to calculate the bacterial count, the experimental water selection Zhabei Shanghai water plant water, boil sterilization standby. In the 27 combination groups, the dosage of 1.4 ~ 3.4 mg / L, the time of 10 ~ 30 minutes, the water temperature of 5 ~ 30 ℃, pH5 ~ 9, except the water temperature of 5 ℃ and PH9 7,19 combination group sterilization rate 99,94%, the remaining 25 combinations of groups have reached the rate of 99.99%.
