Gold Patent Award for Circular Economy Association In 2018

In the field of water treatment, gas floatation is a common solid-liquid separation technique for the removal of light pollutants in water. At present, the dissolved air floatation method is the most widely used one, but the dissolved air floatation method has been faced with bottleneck problems including low dissolved air efficiency, limited removal of dissolved organic matter, high energy consumption and large occupation area. In order to solve the above problems, the research of "gas floatation separation device (ZL200410073500.4)" has declared the invention patent "one kind of multistage ozone gas floating integration device (ZL 201410616487.6)" in 2004, the patent for invention effectively improve the efficiency of the dissolved air flotation, enhancing the solubility of organic matter removal, and has more practical industrial application value to realize the industrialization.
