The invention relates to a rural domestic
sewage resource classification efficient
treatment system, and belongs to the technical field of
sewage treatment. The
system comprises a black
water treatment tank, a domestic
sewage first-stage treatment tank, a domestic sewage second-stage treatment tank and a domestic sewage third-stage treatment tank, wherein the black
water treatment tank comprises ablack water deodorization tank, an
anaerobic treatment tank, a composting tank, a liquid
fertilizer tank and a
urine tank. According to the
system, domestic black water is intensively collected intothe black water deodorization tank through a black
water collection pipeline; after being deodorized in the black water deodorization tank, the black water flows into the
anaerobic treatment tank, andis subjected to a reaction to generate
methane and black water, the
methane is collected and utilized by a
methane power generation device, and the black water enters the composting tank or the liquid
fertilizer tank; and the black water in the
urine tank and grey water are mixed and pass through the domestic sewage first-stage treatment tank, the domestic sewage second-stage treatment tank and the domestic sewage third-stage treatment tank so as to be purified. According to the invention, the method mainly solves the problem that rural domestic sewage is randomly discharged to pollute the environment, and has important effects in the improvement of rural ecological environments, the improvement of living quality of farmers, the increasing of
resource utilization rate of domestic sewage,and the like.
