On December 24, 2019, Tianjin Municipal Science and Technology Bureau released the "Tianjin City Energy-saving, Low-Carbon and Environmental Pollution Prevention and Control Technology Guidance Catalog" [Fourth Series]. The selected technologies this time are all through engineering demonstrations or user use. With the applied technology, our company's "Membrane Aeration Biofilm Reactor River and Lake Water Purification Technology" was successfully selected.

Membrane aeration biofilm reactor river and lake water purification technology is a new type of sewage treatment technology that combines gas separation membrane technology and biofilm water treatment technology. It is suitable for rivers, lakes, reservoirs and other black and odorous and inferior categories. Water purification field. The microbial membrane grows on the surface of the oxygen-permeable hollow fiber membrane, and the pollutants in the sewage are assimilated into microbial cells fixed on the biofilm or decomposed into inorganic metabolites, thereby purifying the water body. Membrane aerated biomembrane reactor river and lake water purification technology directly places the membrane module system in the river without civil construction, high oxygen utilization, and has outstanding engineering advantages, effect advantages, comprehensive cost advantages and sustainable advantages.

So far, the technology and products of our company have been applied to water environment treatment projects in dozens of cities in China. Some projects have been in continuous operation for more than 6 years and are still in stable work. The water quality is maintained at a good level, the operating cost is low, and the ecology is friendly. A large number of successful cases have repeatedly verified the advanced applicability of our technology, the high quality and excellent performance of our products.
