Stuffing composite rotating bio-disc sheet

The present invention is combined stuffing biological turntable sheet and relates to advanced domestic sewage and industry effluent treating technology in environment engineering science. The biological turntable sheet consists of porous spherical or elastic stuffing, water sprinkling board, frame, rotating shaft and netted cover. The porous spherical or elastic stuffing has 60-120 mm diameter and is made of polyethylene. The spherical stuffing includes two layers of balls, the outer is hollow netted ball and the inner is rotating ball. The elastic stuffing is in circular radial filament structure and is combined into string for suspension.
