| 摘要 |
The invention relates to a process for biological treatment of waste water, comprising gradual treatment of waste water by immobilized microorganisms on fiber carrier at first in anaerobic, and then in aerobic conditions, and at the stage of anaerobic purification fiber carrier is placed half submerged into waste water, and also the part of fiber carrier, placed in gas medium, irrigated by recirculated water from lower part of reactor, that is allowed decreasing the purification degree of waste water to 5-10 % and increasing the oxidation rate of organic substances. |
