Abstract
A method of removing silicon dioxide in the waste liquid is provided. The liquid containing F- is added into the waste liquid containing silicon dioxide to react to obtain a product. A method of processing waste water is further provided. A micro-filter tube contains waste water which contains a first liquid and a second liquid containing silicon dioxide. A first clean step is performed to reduce the concentration of the first liquid to a first concentration. A third liquid is added into the tube to react with the second liquid to obtain a product. A second clean step is performed to reduce concentration of the third liquid which does not react to a second concentration.
