洞库供水,水源地点分散,水体中大肠菌群数一般在5000个/升左右,明显超过国家饮水卫生标准。因此,洞库水非消毒不行。本次试验目的:就现有条件下,找出一种简便、易行、有效的加氯消毒方法,保证部队饮用水安全、可靠。一、对象和方法选择甲、乙两个地区的五个不同容积的洞库井,试用间隔加氯法,即在一次较大量投氯之后,利用其密封保护好,不易污染的优点,以期维持较长时间的消毒效果。根据三杯试验测定各水源耗氯量和余氯量,对五个水源的加氯量试加入4~7mg/L,
Cave water supply, water scattered locations, coliform bacteria in the water generally at about 5000 / liter, significantly more than the national drinking water health standards. Therefore, non-sterilized caves water not work. The purpose of this experiment: to find a simple, easy and effective method of chlorination disinfection under the existing conditions, to ensure that units of drinking water is safe and reliable. I. Object and method Five caverns of different sizes in A and B areas were chosen for trial interval chlorination. After a large amount of chlorine was injected, the advantages of good seal protection and non-pollution were taken advantage of in order to maintain Disinfection for a longer period of time. According to the three cup test to determine the amount of chlorine and residual chlorine in each water source, add chlorine 4 ~ 7mg / L to five water sources,
