The invention discloses a process for preparing
biomass fuel by using rural town
domestic waste and agricultural and
forestry waste. The process comprises the steps of step one, waste
leachate treatment and foul smell deodorization; step two, waste screening, sorting and coarse crushing; step three, non-
organic matter magnetic separation,
winnowing and fine crushing; step four, agricultural and
forestry waste crushing and screening; step five, stirring of waste combustible materials, agricultural and
forestry waste,
sludge and water,
compression molding, airing and
biomass fuel obtaining; andstep six, waste
organic matter adding of
livestock and
poultry manure, and
organic fertilizer obtaining. According to the process, the
biomass fuel can be directly used in a boiler, and the problem that the
livestock and
poultry manure pollutes the environment in a
livestock farm is solved through the
organic fertilizer; for the construction of
waste treatment plants, the investment is small, thecost is low, and implementation is easy; the agricultural and forestry waste is collected with paying performed, so that the income of farmers is increased, and the
pollution is reduced; the
profit rate is high, and operating can last without government subsidy; the
waste gas, the waste liquid and the waste residue are subjected to the
environmental protection treatment so that new
pollution can be avoided.
