Abstract
The invention discloses a composite anaerobic-aerobic process for treating waste paper making wastewater. The method comprises that: the waste paper making wastewater enters a physicochemical treatment unit, and fibers are recycled; and the water yielded from the physicochemical treatment unit is distributed through an air pipe water distributor at the bottom of a composite anaerobic pool, pollutants are removed by anaerobic granular sludge formed by an active sludge layer at the lower part of the composite anaerobic pool, then the wastewater enters an anaerobic filter layer at the upper part of the composite anaerobic pool and is subjected to decomposition and metabolism by using microbes attached and grown on the surface of a filter material and inside pores, the top of the composite anaerobic pool yields water to an aerobic pool, the water yielded from the aerobic pool enters a sedimentation pool, the sludge and the water are separated, and the supernatant fluid water can be directly discharged and also can be recycled for paper making.
