| titleOfInvention | A kind of phosphorus in waste water of removing reclaims the method for tetracycline antibiotics in product |
| abstract | A kind of phosphorus in waste water of removing reclaims the method for tetracycline antibiotics in product, belongs to water pollution control and resource regeneration field, is a kind of method reducing phosphorus recovery Products Eco environmental risk.The method of the invention is: first adopt pre-treating method to remove the suspension in phosphorus-containing wastewater and colloidality is organic, then solid-liquid separation；The pH value of supernatant is adjusted to 8.0-11.0, adds a certain proportion of magnesium source or calcium source carries out ammoniomagnesium phosphate or calcium phosphate crystal precipitation, control the pH stable of reaction at 8.0-11.0 until reaction terminates by adding alkali；Solid-liquid separation again, the precipitate obtained is phosphorus and reclaims product.Phosphorus in waste water can be removed by above-mentioned steps and reclaim the tetracycline antibiotics in product.The present invention, under ensureing the premise that phosphorus reclaims productivity, by removing the organic matter of suspension and colloidality in waste water, reaches to remove the purpose of tetracycline antibiotics, reduces phosphorus and reclaim the Ecological Environment Risk that product is likely to cause. |
