| 摘要 |
The present invention provides a process and apparatus for autothermal aerobic thermophilic treatment of high strength and high temperature wastes. Waste material is injected into a reactor vessel (12) having thermophilic microorganisms to form a volume of bulk liquid in the reactor vessel (12). An oxygen-containing gas is also injected into the reactor vessel (12) for aerobic treatment of the waste material. The oxidation-reduction potential and temperature of the reactor bulk liquid are monitored and at least a selected one of the rate of injection of the oxygen-containing gas, the oxygen-transfer efficiency of the oxygen-containing gas and the volume of bulk liquid in the reactor (12) are adjusted in response to the oxidation-reduction potential and temperature of the reactor bulk liquid to maintain the temperature of the reactor bulk liquid within a predetermined range. |
