| titleOfInvention | Domestication method of microorganisms for COD degradation in polluted water |
| abstract | The invention discloses a method for domesticating microorganisms for COD degradation in polluted water; the steps include: filling a biological contact oxidation tank with clean water, turning on aeration, adding compound bacteria and nutrients, and controlling the water temperature at 20-25°C, The pH value is controlled at 6.8-8.1; the compound bacteria are continuously cultivated; sewage is added to the biological contact oxidation tank to make the dissolved oxygen content 0.2-0.8 mg/L, and then the water inflow is stopped; After 48 to 72 hours, the dissolved oxygen rises back to 3.5 to 4.5 mg/L, and then stops the boring exposure; gradually increases the influent load, so that the concentration of COD in the influent is 3000 to 4500 mg/L, and the microorganisms after successful domestication are obtained. The invention enables the domesticated microorganisms to have better stability, has a higher degradation rate of COD in sewage and sludge reduction, and is a microorganism domestication method with excellent deodorizing effect on sewage. |
