Abstract

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.

Description

technical field [0001] The invention is a sewage treatment technology in the discipline of environmental engineering, and is an advanced technology applied to the treatment of small and medium-sized domestic sewage and industrial waste water. Background technique [0002] At present, biological treatment is the main method of sewage treatment, which can be divided into activated sludge method and biofilm method. Due to the mature technology and reliable equipment, the activated sludge method is widely used in large-scale sewage treatment plants, but it has problems of unstable operation and high energy consumption in small and medium-sized sewage treatment. The main forms of biofilm method are: biological filter, biological turntable and biological contact oxidation method, etc., which are mostly used for small and medium-sized sewage treatment. The biological turntable originated in the former Federal Republic of Germany. Due to its high treatment...
