官方网站膜技术主要是利用压力作为动力，使膜分离的过程中为产生官方网站压，官方网站需要使用水泵给包含了废水或者盐水溶液施压，以用来克服自然渗透压及膜的阻力，让水能够渗透官方网站膜，把水中的有污染的杂质阻挡在官方网站膜的另外一侧。今天就给大家科普下官方网站膜在水处理中的应用。
Reverse osmosis membrane technology mainly uses pressure as power to produce reverse osmosis pressure in the process of membrane separation. We need to use water pump to pressurize the solution containing wastewater or brine to overcome the natural osmosis pressure and membrane resistance, so that water can penetrate reverse osmosis membrane and prevent the contaminated impurities in water from reverse osmosis. The other side of the membrane. Today, we will give you the application of reverse osmosis membrane in water treatment under popular science.
1.常规应用：水作为官方网站日产生活中不可或缺的物质条件，目前已经走向了日益匮乏的状态，现在全球官方网站水处理装置已经可以处理将近日均百万吨的废水。
1. Conventional application: As an indispensable material condition for our daily production and life, water has become increasingly scarce. Now the global reverse osmosis water treatment device can handle nearly one million tons of wastewater in recent days.
2.城市污水方面：官方网站膜水处理技术目前在城市污水以及二级出水回用及中水回用方面已经开始受到高度重视。
2. Urban sewage: Reverse osmosis membrane water treatment technology has begun to receive high attention in urban sewage, secondary effluent reuse and intermediate water reuse.
3.重金属废水处理：含重金属离子废水的一般处理方法主要是即将废水中溶解的重金属转化成沉淀或更加易于处理的形式，其实大多数情况下比较后都是填埋处理，依然存在二次污染的危害。
3. Treatment of heavy metal wastewater: The general treatment method of wastewater containing heavy metal ions is mainly to convert dissolved heavy metals into precipitation or more easily treated form. In fact, most of the cases are landfill treatment, and there are still secondary pollution hazards.
4.含油废水方面：含油废水是一种排放量大并且面积广的工业废水，若直接排入水体，会对环境造成严重污染。像油田采出水处理到锅炉用水水质于是处理后的水回用于电站锅炉给水。
4. Oily wastewater: Oily wastewater is a kind of industrial wastewater with large discharge volume and wide area. If it is discharged directly into the water body, it will cause serious pollution to the environment. Such as oilfield produced water treatment to the boiler water quality and then the treated water is reused for power plant boiler feed water.
