An apparatus for treating sewage and wastewater is provided to remove nitrogen and phosphorous as well as organic matter, and reduce the amount of solid generated during treatment of the sewage and the wastewater. A raw water input reactor(100) discharges raw water and inputs the raw water into an anaerobic bio-filtration reactor(200). The raw water input reactor has a flocculant input unit(101), wherein the flocculant input unit inputs a flocculant, alum, into the raw water at an input rate of 60-80 mg/L to remove phosphorous from sewage and wastewater. The anaerobic bio-filtration reactor includes a raw water input port(401), a sludge discharge port(204), a stirrer driven by a motor, a digestion bath(201) filled with carriers, and an anaerobic filter bath(202). An aerobic bio-filtration bath(300) is connected to the anaerobic bio-filtration reactor through a transfer pipe. The aerobic bio-filtration bath includes a diffuser(302) for diffusing air inputted by an external ventilator, a sludge discharge port(301), and a final water outflow port(305). The aerobic bio-filtration bath contains media therein. |
