| Fuxin is a famous coal habitat in our country, it had more than hundred years coals mining history. The gangue by coal mine mining has spread the Fuxin entire area. Facing the massive gangues resources, this paper carries on the comprehensive gangue ingredient analysis, selecting the reasonable technical process to carry on the chemical production. This is not only may place the unemployed person but also may, mobut also may recycle energy and creatie economic efficiency for nation.This research uses the Fuxin gangue to study highly effective inorganic high. Turns into the water treatment medicament from massive industrial production reject. This paper has carried on the chemical composition analysis to the Fuxin gangue, designs a new technical process system through the massive experiments to crate the Polymeric Ferric Aluminum Silicate Sulfate, scientifically obtains by using the orthogonal experiment method with the least most experimental number of times best response condition for withdrawing the alkali and the silicon the gangue. Through analysis the coagulant alkalize, the waste water pH value, the coagulation time, this paper use the single factor cut-and-try method to discuss separately to the waste water processing effect influence. The experiment proved that, We uses this craft to produce PFASS, the product processing effect is good, COD average removing rate is about 45%, the decolorization rate also above 85%, the water leakage water quality basically conforms to the requirement.The findings indicated that: We uses this craft to produce PFASS, the product processing effect well. It also the price is inexpensive, has the good market prospect. |
