The invention discloses a rural domestic
sewage integrated advanced treatment device. The rural domestic
sewage integrated advanced treatment device comprises a grit tank, an anaerobic tank, an anoxic tank, an aerobic tank, a membrane
biological reaction tank and a baffling type autotrophic
denitrification filter tank which are sequentially connected along the
sewage treatment direction; the baffling type autotrophic
denitrification filter tank comprises a
sewage treatment area for filtering sewage and a
clean water tank communicated with a water outlet of the
sewage treatment area, and partition plates are arranged in the
sewage treatment area in the vertical direction so as to divide the sewage treatment area into a plurality of treatment chambers; and each treatment chamber is filled with an autotrophic functional filler for providing
electron donors for microorganisms in the sewage, each partition plate is provided with a connecting section for communicating the adjacent treatment chambers, and the connecting sections on the adjacent partition plates are arranged in a staggered manner, so that the sewage in the sewage treatment area flows in an S-shaped flow direction. Under a same occupied area, the flow path of the sewage is maximized, the
denitrification effect is improved, only a small
filter material area is needed for completing the same
water treatment amount, and the
filter material cost is saved.
