| Abstract: | NH3 -N removal in wastewater by chemical precipitation was studied. The effect of different operational conditions such as pH values in solutions,formulas of precipitants,and initial molar concentration of NH3 in wastewater on the NH3 removal efficiency was investigated experimentally. Under the optimal conditions,about 99% of NH3 in wastewater can be removed and the concentration of NH3 in water through treatment is less than 1 mg/L(lppm). The reaction mechanism of chemical precipitation process was explored. |
