| 在地下水处理中，去除硬度是一个重要的环节。硬水是指含有较多可溶性钙、镁化合物的水，这些化合物会导致水在加热时形成水垢，影响设备的正常运行和水的口感。以下是哈尔滨水处理公司一些常用的去除地下水硬度的方法： In groundwater treatment, removing hardness is an important step. Hard water refers to water containing a high amount of soluble calcium and magnesium compounds, which can cause water to form scale when heated, affecting the normal operation of equipment and the taste of water. Here are some common methods used by Harbin Water Treatment Company to remove groundwater hardness: 一、加热煮沸法 1、 Heating and boiling method 这是生活中常用的降低水硬度的方法。通过加热煮沸，可以使水中的碳酸氢钙和碳酸氢镁发生分解，生成难溶的碳酸钙和氢氧化镁沉淀，从而降低水的硬度。但这种方法适用于暂时硬度的去除，对于永久硬度效果不佳。 This is a commonly used method in daily life to reduce water hardness. By heating and boiling, calcium bicarbonate and magnesium bicarbonate in water can be decomposed to form insoluble calcium carbonate and magnesium hydroxide precipitates, thereby reducing the hardness of water. But this method is suitable for temporary hardness removal and has poor effect on permanent hardness. 二、药剂软化法 2、 Pharmaceutical softening method 药剂软化法是利用化学沉淀的原理，通过向水中投加适当的化学药剂，将水中的硬度转化为难溶盐而被去除。常用的药剂有石灰、纯碱、磷酸盐等。 The chemical softening method utilizes the principle of chemical precipitation by adding appropriate chemical agents to water to convert the hardness of the water into insoluble salts and remove them. Common medicines include lime, soda ash, phosphate, etc. 石灰软化：适用于硬度高、碱度高的水。石灰可以与水中的碳酸氢钙和碳酸氢镁反应，生成碳酸钙和氢氧化镁沉淀，同时去除水中的二氧化碳。此外，石灰还可以将镁的非碳酸盐硬度转化为钙硬度。 Lime softening: suitable for water with high hardness and alkalinity. Lime can react with calcium bicarbonate and magnesium bicarbonate in water to form calcium carbonate and magnesium hydroxide precipitates, while removing carbon dioxide from water. In addition, lime can also convert the non carbonate hardness of magnesium into calcium hardness. |
