PURPOSE: A method and an apparatus for continuously eliminating phosphorus and suspended materials from wastewater are provided to improve the accuracy and the efficiency of a sludge dehydrating process by easily coagulating suspended materials containing high concentration phosphorus. CONSTITUTION: A suspended material collecting chamber and an inclined discharging pipe are installed at the inner upper center of a first gravity acceleration-rapid precipitating bath(40). The suspended materials of wastewater are collected in the suspended material collecting chamber and are discharged to the outside through the inclined discharging pipe. A back washing nozzle is installed at both sides of the first gravity acceleration-rapid precipitating bath and collects the suspended materials in the suspended material collecting chamber based on the spray of purifying water. The wastewater through the first gravity acceleration-rapid precipitating bath is introduced into a first aerating bath(50). A second gravity acceleration-rapid precipitating bath(40') is in connection with one side of the first aerating bath to eliminate precipitated and suspended materials. Liquid material is introduced into a second aerating bath to precipitate active sludge from the wastewater.
