    摘要： A domestic and industrial type sewage biological purification system including a de-nitrification section (D1), an oxy-nitrification section (R1,R2), a settling section and a sterilizing section (TH2), said system comprising a single vertical structure including the above mentioned section therewithin. Said structure is partitioned by sloping separators (6,7) in three portions wherein the intermediate portion comprises the de-nitrification section (D1) connected with the oxy-nitrification section which comprises two mutually concentrical columns (R1,R2) wherein the outer one is connected with the settling section (TH2) which comprises the upper portion of this structure. The settling section is connected with the sterilizing section comprising the lower portion of this structure. Sewage enters the de-nitrification section, moves downwards along the outer column, rises through the inner column while mixing with oxygen and/or air, moving then downwards in the settling section. Water moves from the settling section to the sterilizing section, and leaves the system in a purified condition.
