PURPOSE: A biological sewage processing sludge bulking enhancer, and a water treatment method using thereof are provided to improve the settling ability of sludge inside a settling tank, for improving the bulking phenomenon. CONSTITUTION: A biological sewage processing sludge bulking enhancer contains 30~50wt% of ethylamine, 30~50wt% of polyaluminum chloride, and 10~40wt% of water. A water treatment method using the sludge bulking enhancer comprises the following steps: biologically decomposing organic compounds contained in sewage flowing into an aeration tank(10); solid-liquid separating the sewage inside a settling tank(40), and discharging supernate to the outside; and returning activated sludge precipitated on the bottom of the settling tank to the aeration tank. The sludge bulking enhancer is inserted into the sewage flowing into the settling tank. |
