在水处理工作中,算尺是很有用的工具。据称,国外较大的水处理公司都有自己的算尺,如美国Nalco公司,有能计算pH_5、雷兹纳指数及药剂成本等三功能的算尺。据了解,国内还没有,因此,试做了一把能计算:pH;s朗格指数;雷兹纳指数;二氧化碳、碱度及pH的关系;水在不同温度下的pH值;排污量及补水量等七功能的算尺。它可用于给水、循环冷却水及锅炉水的水质计算。本算尺的结构如图所示。现将其应用实
In the water treatment work, the ruler is a very useful tool. Allegedly, foreign large-scale water treatment companies have their own scales, such as the Nalco Company in the United States, which has three functions that can calculate pH_5, Rezina index, and pharmaceutical cost. It is understood that there is no domestic one. Therefore, one can calculate: pH;s Lange index; Rezina index; relationship between carbon dioxide, alkalinity and pH; pH value of water at different temperatures; The amount of water and other seven functions of the scale. It can be used to calculate the water quality of water supply, circulating cooling water and boiler water. The structure of the scale is shown in the figure. Apply it now
