Abstract
The invention discloses a biomembrane process platy supporter and a production method thereof. The biomembrane process platy supporter is characterized in that the platy supporter is of a platy structure formed by hot rolling melt-blow fiber and powder supporters, wherein the powder supporters are uniformly distributed on the melt-blow fiber. As a continuous pore structure is formed on the cross section of a waste film, the waste ultrafiltration membrane is decomposed by physical refining, made to be the platy supporter, placed in a biomembrane tank as the supporter and used as a microbe carrier for adsorbing and decomposing organics, so that the treatment efficiency of the biomembrane tank is improved, and the waste ultrafiltration membrane can be recycled. Besides, the mobility of the platy supporter is limited, the platy structure and the powder supporters distributed on the platy structure are beneficial to biomembrane culturing, and the application range is wider.
