| titleOfInvention | The processing method of arsenic-containing waste water |
| abstract | The invention provides a kind of processing method of arsenic-containing waste water, including：A) by waste water and the first reaction material hybrid reaction, press filtration, filtrate is obtained；First reaction material includes hydrogen peroxide, ferric iron source compound, calcium oxide and diatomite；B) by the filtrate and the second reaction material hybrid reaction, press filtration, processed waste water is obtained；Second reaction material includes ferric iron source compound and polyacrylamide.The present invention is by hydrogen peroxide oxidation, then flocculating setting after ferric iron source compound, calcium oxide and diatomite Coagulation and Adsorption, tentatively reaches the purpose of arsenic removal；Then reach the purpose of final arsenic removal by ferric iron source compound oxidation and polyacrylamide coagulating sedimentation.Test result indicates that the processing method of the arsenic-containing waste water by the present invention, the water quality arsenic content that final process obtains is below 0.5mg/L. |
