| titleOfInvention | Method for biological treatment of industrial wastewater |
| abstract | The invention discloses a method for biologically treating industrial wastewater, wherein the industrial wastewater to be treated sequentially passes through an oil separation tank, an anaerobic tank, an anoxic tank, an aerobic tank and a secondary sedimentation tank, and the method comprises the following steps: 1) introducing industrial wastewater to be treated into an oil separation tank for treatment, and recovering floating oil on the upper layer of the oil separation tank; 2) introducing the wastewater treated by the oil separation tank in the step 1) into an anaerobic tank; 3) introducing the wastewater treated by the anaerobic tank in the step 2) into an anoxic tank; 4) introducing the wastewater treated by the anoxic tank in the step 3) into an aerobic tank, and adding nitrifying bacteria according to the proportion of adding 1kg of nitrifying bacteria to every 10L of wastewater every day; 5) introducing the wastewater treated in the step 4) into a secondary sedimentation tank, and directly discharging the wastewater treated in the secondary sedimentation tank. The invention is a biological treatment method of industrial wastewater, which can effectively treat the floating oil in the industrial wastewater and has good denitrification and dephosphorization effects. |
