The invention provides a continuous
reproduction technology using
biomass wastes and a waste liquid. The technology comprises the following steps: crushing the
biomass wastes,
drying, molding, sending the obtained
biomass wastes to a
dry distillation furnace, and carrying out
dry distillation to obtain
charcoal and crude
dry distillation gas; cooling
charcoal, packaging to obtain a finished product, condensing the crude dry
distillation gas to obtain a
gas phase which is
biogas, carrying out alkaline washing, separating, conveying to make the
biogas enter a gas storage cabinet, and allowing the
biogas to enter users through a
pipe network; standing a refluxing waste liquid obtained after condensation of the crude dry
distillation gas to realize layering and obtain an upper layer which is wood vinegar and a lower layer which is wood
tar, collecting the wood
tar, and packaging the collected wood
tar to obtain a finished product; and determining
organic matter components of the wood vinegar through
gas chromatography-
mass spectrometry, and respectively preparing a bacteriostasis and deodorization agent and an
environmentally friendly botanical
snow melting agent according to the content of
acetic acid. The technology has the characteristics of continuousness, no emission of the waste liquid, and
environmental protection, and solves the high value utilization problem of the waste liquid generated in the preparation of gas through biomass
pyrolysis; and the bacteriostasis and deodorization agent has strong bacteriostasis, the
ammonia odor removal rate can reach 100%, and the
snow melting agent has the advantages of no
corrosion, low
snow melting temperature,
chlorine harm eradication and excellent
environmental protection performance.
