Develop green water purification technology
Membrane technology, including conventional nanofiltration, reverse osmosis.
There are also efficient technologies, including graphene, carbon nanomaterial composite technology.
In addition, like pretreatment, large-capacity adsorption technology and efficient oxidation technology, efficient catalysis technology, etc., promote the application of new green materials and new technologies to remove new pollutants in clean water.
The new membrane technology includes the development of some new membrane materials that are resistant to high temperature, pollution and acid and alkali, have relatively stable performance, and are moderately costly.
01
Although the membrane and various adsorption, oxidation, ion exchange, can be organically combined, but for different water quality characteristics and for different water purification water service objects, the membrane process is optimized to achieve the highest cost-effectiveness ratio.
Therefore, the development of new membranes and the removal of new pollutants are also very important.
The new membrane is now also a controversial topic, and science is discovered in the process of debate, in the process of practice, through scientific testing, and summed up.
Therefore, the technology of the new membrane has not yet had a very unified definition or concept that everyone recognizes.
The new film may have the following connotations:
First, on the basis of the traditional film, the functional materials are composited, especially the functional materials based on nanomaterials, which increases the performance of the traditional film.
The second is to replace the traditional membrane with a new membrane, such as graphene membrane, and the membrane making process is different, in addition, the traditional membrane cannot be purified or purified by relatively poor water quality treatment, and the membrane can get good results.
So membranes that meet the following conditions:
01
New membrane technology
For example, the nanofiltration of the mixing mechanism, the nanoparticles such as molybdenum disulfide, metal-organic framework particles, and gold nanoparticles are incorporated into the preparation process of the traditional polyamide nanofilm to obtain a typical mixed matrix film with good performance.
02
New membrane technology
In addition, using ultrafiltration membranes as a medium to adsorb classification membranes, we are also studying the purification effect of drugs or personal care products.
03
New membrane technology
At the same time, the membrane separation technology and advanced oxidation process, or the organic combination of photocatalytic oxidation technology units, can effectively remove refractory pollutants in industrial wastewater, such as antibiotics.

Also pay attention
The role of nanomaterials in the control of new pollutants
Just now we mentioned that a considerable part of the new membrane is in the use of nanomaterials to improve the traditional microfiltration, nanofiltration, ultrafiltration, the purification effect of new pollutants is better than the traditional membrane, we want to strengthen the research in this regard.
