The invention discloses a method for producing
compost by using beer production waste. The method includes preparing raw materials: according to a weight ratio, mixing one or more of
dewatered sludge, waste
lees and
silica gel sludge which are discharged through beer production, determining pH of the materials to be 7-7.5 and regulating a
water content to be 55-60%; composting: adding the prepared raw materials in to a
compost reactor, feeding in air continuously, guaranteeing that the reactor operates under an aerobic state, stacking for 13-17 days to finish the composting, during the stacking process, turning the stack once every 2-3 days, and detecting pH, temperature,
oxygen uptake rate and humification coefficient of the stack; analyzing a
compost product: measuring content of various elements of an end product compost, screening and
grinding the compost after stabilizing and
drying, and applying directly to an
organic fertilizer or an organic or
inorganic compound fertilizer. The method is simple in operation, low in operation cost, free of secondary
pollution and convenient to manage.
