在众多的净水设备当中，净水机和软水机是两种较为常见的，不少用户在挑选的时候，
Among many water purification equipment, water purifier and water softener are two common ones. Many users choose them,
有点茫然了，净水机和软水机哪个好呢？对于这个净水器知识问题，不同的用户有不 同的需求，所以给出的答案也是不一样的。下面就从净水机和软水机的原理、功能和 优缺点来进行详细的介绍。
A little confused, which is better, water purifier or water softener?
For this water purifier knowledge problem, different users have
different needs, so the answers are different. The principle, function,
advantages and disadvantages of water purifier and water softener are
introduced in detail below.
净水器知识——净水机净化效果好，使用时间长
Knowledge of Water Purifier - water purifier has good purification effect and long service time
净水机采用 0.01 微米的超滤膜分离技术，能有效祛除水的泥沙，铁锈，悬浮物，胶体，
细菌，病毒，大分子有机物等有害物。净水机过滤的密度是比较高的，经过净水机过
滤之后的水，如同矿泉水一样，是可以直接来饮用的。净水机的流量大，可以满足用
户人数比较多的需求量。净水机的滤芯使用时间长，并且可以实现自动清洗滤芯的效 果，避免出现二次污染。
The water purifier adopts 0.01 micron ultrafiltration membrane
separation technology, which can effectively remove harmful substances
such as sediment, rust, suspended solids, colloids, bacteria, viruses,
macromolecular organics and so on. The filtration density of the water
purifier is relatively high. The water filtered by the water purifier,
like mineral water, can be directly drunk. The flow of the water
purifier is large, which can meet the demand of a large number of users.
The filter element of the water purifier has a long service time, and
can realize the effect of automatic cleaning of the filter element to
avoid secondary pollution.
净水机是不需要消耗电能的，同时也不会产生废水，不会造成浪费。不过净水机也有
一些缺点，比如对水质比较硬的地区，去除水垢和水碱的效果不佳，而适用中等以下
硬度地区。水中所存在的异味是不能彻底消除掉的，不能彻底去除水中重金属，所以 水的口感比较差，饮用起来并不是很好。净水机更换滤芯比较麻烦。
The water purifier does not need to consume electric energy, and will
not produce waste water and waste. However, the water purifier also has
some disadvantages. For example, in areas with hard water quality, the
effect of removing scale and water alkali is poor, but it is suitable
for areas with medium hardness or less. The peculiar smell in the water
can not be completely eliminated, and the heavy metals in the water can
not be completely removed. Therefore, the taste of the water is poor and
it is not very good to drink. It is troublesome to replace the filter
element of the water purifier.
净水器知识——软水机可去除水碱和水垢
Knowledge of Water Purifier - water softener can remove water alkali and scale
软水机根据离子交换的原理，即用 Na+交换 Mg2+Ca2+，使水中的硬度降低到 70 毫
克/升以下成为软水，此水处理设备主要功能是祛除水碱，水垢。软水机可以将水垢去
除掉，水碱也是没有问题的。在使用的时候，出水量比较大，是不会降低水压的，清
洁能力强。日常饮用可以放心，而且洗脸、洗澡等，还能起到保护肌肤，美容养颜的 功效。用来清洗衣物等，节约洗涤用品降，低家务强度。软水机水处理设
According to the principle of ion exchange, the softener exchanges Mg2 +
Ca2 + with Na + to reduce the hardness of water to less than 70 mg / L
and become soft water. The main function of this water treatment
equipment is to remove water alkali and scale. The water softener can
remove the scale, and there is no problem with water alkali. When in
use, the water output is relatively large, the water pressure will not
be reduced, and the cleaning ability is strong. Daily drinking can rest
assured, and washing and bathing can also protect the skin, beauty and
beauty. It is used to clean clothes, save washing supplies, reduce
housework intensity. Water treatment equipment of softener
