| titleOfInvention | A kind of method utilizing the nickeliferous sewage of modification infusorial earth advanced treating |
| abstract | Utilize a method for the nickeliferous sewage of modification infusorial earth advanced treating, belong to environment remediation technical field.Be made into the aqueous solution that concentration is not less than three (methylol) aminomethane of 2mmol/L, with salt acid for adjusting pH value to 8-8.8, obtain Tris-HCl cushioning liquid; Get a certain amount of Tris-HCl cushioning liquid, add the polyphenol compound that concentration is not less than 2mmol/L under stirring, dissolve completely; Add diatomite, addition is no more than 500g/L, and sealing and standing more than 12 hours after stirring, obtains the diatomite of modification; Washing, dries naturally; Be packed into post, the sewage that nickel concentration is no more than 0.8mg/L pours in Filter column, keeps being no less than 3 minutes, releases the advanced treating that filtrate can realize nickeliferous sewage.Low in raw material price, environmental friendliness, equipment is simple; Nickeliferous sewage can be realized process fast continuously, easy and simple to handle; Modification infusorial earth is renewable to be recycled. |
