NOVELTY - Domestic sewage treatment device comprises horizontal tank (1), domestic sewage inlet (2) on front end of horizontal tank, window (4), and horizontal clean water outlet (9). The tank body end is connected with deposition corrosion chamber (3). The sewage inlet of horizontal tank body is connected in series with non-sand filter chamber (6), activated carbon absorbing chamber (7), and bioenzyme catalysis chamber (8). The corrosion deposition chamber is connected with sand filter chamber with clapboard (16).    USE - Device for treating domestic sewage.    ADVANTAGE - The device has low processing cost and good purifying effect, improves the living environment, reaches the national comprehensive discharge standard for treated domestic sewage, and effectively solves the problem of domestic sewage and river polluted underground water, which avoids the underground pipeline blocking, reduces the sewage processing factory, and improves the dredging convenient service life of the device.    DETAILED DESCRIPTION - Domestic sewage treatment device comprises horizontal tank (1), domestic sewage inlet (2) on front end of horizontal tank, window (4), and horizontal clean water outlet (9). The tank body end is connected with deposition corrosion chamber (3). The sewage inlet of horizontal tank body is connected in series with non-sand filter chamber (6), activated carbon absorbing chamber (7), and bioenzyme catalysis chamber (8). The corrosion deposition chamber is connected with sand filter chamber with clapboard (16). Floating slag separating net is set between filter chamber and activated carbon absorbing chamber. Lower part of clapboard is connected between active absorbing chamber and bioenzyme catalysis chamber. The upper part of clapboard is set with connecting ports. The bioenzyme catalysis chamber and the clean water outlet are connected with each other.    DESCRIPTION OF DRAWING(S) - The drawing is a schematic view of domestic sewage treatment device.
