Background

The biofilm method is a method for treating organic sewage by using microorganisms attached and grown on the surfaces of certain solid matters. The biological membrane is an ecological system consisting of highly dense aerobic bacteria, anaerobic bacteria, facultative bacteria, fungi, protozoa, algae and the like, and a solid medium attached to the biological membrane is called as a filter material or a carrier. The biomembrane self-filtering material can be divided into an anaerobic layer, a good air layer, an attached water layer and a moving water layer outwards. The principle of the biomembrane method is that the biomembrane firstly adsorbs organic matters attached to a water layer, the organic matters are decomposed by aerobic bacteria of an aerobic layer and then enter an anaerobic layer for anaerobic decomposition, and a flowing water layer washes away the aged biomembrane to grow a new biomembrane, so that the aim of purifying sewage is fulfilled.
