Progress In Membrane Technology For Industrial Wastewater Treatment

According to Wang Xinfang, President of China Environmental Protection Industry Association, China's membrane technology has made great progress in wastewater treatment. In the future, membrane technology has wide prospects for water pollution control in China.

Wang Xinfang said that in recent years, membrane technology in China, including membrane bioreactor, reverse osmosis and membrane integration technology, has made great progress in the treatment of domestic sewage and industrial waste water in cities and towns. Among them, membrane technology has many successful operations in the treatment of domestic sewage in cities, and membrane technology has also been successfully applied to industrial wastewater treatment.

Membrane is a material with selective separation function and can be separated in molecular range. The aperture of the membrane is generally micron scale. Membrane technology is actually membrane separation technology. Compared with traditional separation technology, membrane technology has the advantages of high efficiency, energy saving, environmental friendliness, easy process control, convenient operation, and easy integration with other technologies.

Membrane technology is Water purification And the best means of purification, using membrane can remove suspended solids, bacteria, toxic metal substances and organic matter in water, and greatly improve water quality.

Wang Xinfang said, Membrane technology For domestic sewage, industrial waste water The disposal and utilization of resources are of strategic importance. Although our country is strengthening environmental protection work, the situation of environmental protection is still grim. In 2008, the total amount of wastewater discharged from the whole country, including industrial waste water and domestic sewage, was 57 billion 200 million cubic meters, and some rivers and lakes were already overburdened.

The use of membrane technology can significantly reduce the amount of pollutants discharged, especially in industrial wastewater such as printing and dyeing, leather, electroplating, coking and brewing. Membrane technology is one of the most important technologies for treating industrial wastewater.

In order to enhance the popularization of membrane technology in wastewater treatment, the relevant departments of the state have put the development of membrane technology and membrane materials in the planning of cultivating new industries.

The China Environmental Protection Industry Association will also cooperate with the environmental protection departments to promote the promotion of membrane technology in the wastewater treatment field in the economically developed areas. We should do a good job in demonstration projects of membrane technology for water pollution control in key drainage areas, and establish a market incentive mechanism to speed up the promotion of membrane technology in the field of wastewater treatment.
