Biofilm water treatment method

1. Biological filter: Make the wastewater flow through the biofilm growing on the surface of the filter material, and through the material exchange and biochemical action between the two sides, the organic matter in the wastewater is degraded to achieve the purpose of water purification.
2. Biological turntable: It is composed of several closely spaced disks fixed on a horizontal axis. A layer of biofilm grows on the surface of the continuously rotating disk to achieve the effect of water treatment and purification.
