| Abstract: | The effluent of wastewater treatment plant is treated by combing diatom earth and biological contact oxidation process. The concentration of ammonia nitrogen decreases from 10 mg/l to 0. 5mg/l, the removal rate reaches 70% to 95%. The removal rate of total phosphorus is higher than 95% by passing diatom earth clarification tank. The process also has excellent removal effects on chromaticity color and degree of turbidity. |
