3、注意收集分析各种信息，不断改进工作

水质对冷却设备的影响是缓慢地，往往不引起人们的重视，一旦出现问题。

几乎没有什么高效的方法可纠正。因此，必须重视对各种信息的收集，做到防微杜渐，预先处理。系统发生腐蚀、结垢，在水质指标中总会有所反映，尽管这种反映是细微的，容易被忽略。

如水中总铁浓度上升甚至居高不下，说明系统产生了腐蚀；水中的浊度、异养菌、粘泥、正磷上升，或Ca2+与其他离子浓度比例失调，都说明系统可能有沉积发生和有微生物问题。冷却循环设备大、小修时，换热设备打开进行检查

，更是检验水处理效果难得的机会。当换热设备打开时，需要仔细观察设备是否有腐蚀、结垢、生物粘泥的问题存在，这是对水处理效果的真正判断。有时在可能的情况下，专门开一两台设备供检查以取得可靠的信息。对所取垢样进行分析，也能帮助判断出问题所在。

3. Pay attention to collecting and analyzing various information and continuously improve the work

The impact of water quality on cooling equipment is slow and often does not attract attention, once problems occur. There are few efficient methods to correct. Therefore, it is necessary to attach importance to the collection of various types of information, so as to prevent the gradual decline and deal with it in advance. Corrosion and scaling of the system will always be reflected in the water quality indicators, although this reflection is subtle and easily overlooked. If the total iron concentration in the water rises or even remains high, it indicates that the system has undergone corrosion; The increase in turbidity, heterotrophic bacteria, slime, and positive phosphorus in the water, or the imbalance in the concentration ratio of Ca2+to other ions, all indicate that there may be sedimentation and microbial problems in the system. During major and minor repairs of cooling circulating equipment, opening the heat exchange equipment for inspection is a rare opportunity to verify the effectiveness of water treatment. When the heat exchange equipment is turned on, it is necessary to carefully observe whether there are corrosion, scaling, and biological sludge problems in the equipment, which is a true judgment of the water treatment effect. Sometimes, when possible, one or two devices are specially opened for inspection to obtain reliable information. Analyzing the scale sample taken can also help identify the problem

4、注意工艺条件对水处理效果的影响

循环水是用于换热设备的冷却介质，其引起腐蚀、结垢等问题与设备本身的工艺条件也有很大关系，特别是工况设计低流速、温度高的设备，影响更为显著。这就是同一循环水系统中，不同工况的设备，其腐蚀或结垢倾向表现出很大不同的原因之一。

4. Pay attention to the impact of process conditions on water treatment efficiency

Circulating water is the cooling medium used for heat exchange equipment, and its causes of corrosion, scaling, and other problems are also greatly related to the process conditions of the equipment itself. Especially for equipment with low flow rate and high temperature designed under operating conditions, the impact is more significant. This is one of the reasons why the corrosion or scaling tendencies of equipment under different operating conditions in the same circulating water system differ greatly.

补给水的水质管理

补给水水质发生变化也会影响循环水水质，补给水PH、悬浮物、总铁、氯离子等超过规定指标时，将会造成循环水水质变化，甚至恶化。

Quality management of make-up water

Changes in the quality of make-up water can also affect the quality of circulating water. When the PH, suspended solids, total iron, and chloride ions of make-up water exceed the specified indicators, it will cause changes in the quality of circulating water, or even deterioration.

正常运行阶段水处理技术的关键

就是如何妥善处理好化学水处理中的水质指标、药剂方案及浓缩倍数的关系。水质指标、药剂方案与浓缩倍数是相辅相成的、互相牵制的

Key points of water treatment technology in normal operation stage

It is how to properly handle the relationship between water quality indicators, reagent schemes, and concentration multiples in chemical water treatment. Water quality indicators, pharmaceutical schemes, and concentration multiples are complementary and mutually constraining
