| Abstract: |
| By analysis,choose the ion-exchange method as a basic method to reduce the total hardness and NO3-N content in the drinking water.Through the experiments,technologic conditions which reducing the total hardness by using the sodium ion-exchange method are given;the method which can remove NO3-N from drink water is studied by chlorine ion-exchange.According to the two methods,the technical flow that reducing the total hardness and NO3-N content in the drinking water is put forward.The method has been applied ... |
