Abstract:
    This invention relates to a method for preparing organic fertilizer containing microbes by using waste filler and active sludge. The method comprises: placing waste filler and active sludge at a weight ratio of 1:(1-5) into an anaerobic fermentation tank, adding water to immerse waste filler and active sludge, keeping the fermentation tank at 10-50 deg.C and DO of 2-6 mg/L, and stirring at a low speed for 7-30 days to degrade waste filler and obtain the product. The method can degrade waste filler, prevent second pollution, and has such advantages as low cost and simple process. The waste filler is abandoned hollow fibers of natural plants containing saponins used as biological membrane reactor filler.
