NOVELTY - A biogas septic and sewage treatment system device of high-rise building comprises biogas generation system and sewage treatment system.    USE - The biogas septic and sewage treatment system device used for sewage treatment in town high-rise building, especially for producing biogas with domestic sewage, and purifying and reusing sewage.    ADVANTAGE - The present invention provides biogas septic and sewage treatment system device, which can effectively processes domestic sewage and uses domestic sewage to produce biogas. It comprehensively utilizes the domestic sewage. The domestic sewage is reused after purification.    DETAILED DESCRIPTION - A biogas septic and sewage treatment system device of high-rise building comprises biogas collector (1), biogas generating tank (2), biogas slurry connected pipe (3), biogas tank shaft (4), biogas tank helical vane (5), conveying pipe (6), SBR aeration tank (7), reclaimed water connected pipe (8), film separation unit sedimentation tank (9), sterilizing pool (10), reclaimed water discharge pipe (11), high pressure pump (12), biogas slag pump (13), biogas slag excretory duct (14), domestic sewage pipe (15), and sludge port (16). Biogas collector (1), biogas generating tank (2), biogas slurry connected pipe (3), biogas tank shaft (4), biogas tank helical vane (5), conveying pipe (6), high pressure pump (12), biogas slag pump (13), biogas slag excretory duct (14), and domestic sewage pipe (15) form the biogas generation system. Conveying pipe (6), SBR aeration tank (7), reclaimed water-connected pipe (8), film separation unit sedimentation tank (9), sterilizing pool (10), reclaimed water discharge pipe (11), and high-pressure pump (12) form sewage treatment system. The biogas tank shaft (4) is vertically mounted in the biogas-generating tank (2). The biogas tank helical vane (5) is mounted on the biogas tank shaft (4). The conveying pipe (6) is mounted on the upper part of biogas generating tank (2) and connected to the high-pressure pump (12). The biogas slag excretory duct (14) is mounted on the bottom of the biogas-generating tank (2) and assembled with the biogas slag pump (13). The domestic sewage pipe (15) is mounted on the lower part of the biogas-generating tank (2). The conveying pipe (6) is connected to SBR aeration tank (7) through high pressure pump (12). The SBR aeration tank (7) is connected to film separation unit sedimentation tank (9) through reclaimed water connected pipe (8). The film separation unit sedimentation tank (9) is connected to sterilizing pool (10) through reclaimed water connected pipe (8). The end of sterilizing pool (10) is connected to reclaimed water discharge pipe (11).
