And too much nitride and phosphate will cause the water abundant in alimentation. For long time, city wastewater factories mainly remove COD and SS and the effect of nitride and phosphate removal is usually not good. So how to control and decrease the concentration of nitride and phosphate in the wastewater and dispose of slightly polluted water has become the new task in the modern wastewater dispose field.
