The invention provides a
biogas slurry ecological treatment breeding
system and a working method thereof. The
biogas slurry ecological treatment breeding
system comprises a
solid-liquid separation tank, a
decomposition treatment tank, an
aeration treatment tank, a pH value regulation tank, an
algae culture tank and an animal raising tank which are sequentially arranged according to a treatment process. The
solid-liquid separation tank, the
decomposition treatment tank, the
aeration treatment tank, the pH value regulation tank, the
algae culture tank and the animal raising tank are sequentially connected in series end to end through connectors. The
solid-liquid separation tank is used for carrying out
sedimentation treatment and disinfection treatment on
biogas slurry; the
decomposition treatment tank is used for carrying out anaerobic and aerobic
catabolism treatment on biogas slurry; the
aeration treatment tank is used for carrying out aeration treatment on biogas slurry; the pH value regulation tank is used for carrying out supplementing and adjustment on the concentration, the pH value and the nutritive salt ingredient of biogas slurry;
algae are cultured in the algae culture tank, and biogas slurry and biogas are utilized for providing nutrients for algae and are purified by algae; various aquatic animals are raised in the animal raising tank in an isolated mode, and main feed comprising algae is provided for aquatic animals. According to the biogas slurry ecological treatment breeding
system and the working method thereof, a cyclic and ecological culture industry is formed, and the environment is improved.
