| titleOfInvention | A kind of method of ammonia nitrogen in removal electroplating wastewater |
| abstract | The invention belongs to industrial waste water treatment, a kind of method for removing ammonia nitrogen in electroplating wastewater is disclosed, comprises the following steps (1) and adjusts the pH value of electroplating wastewater of the raw material containing ammonia nitrogen to 4~6 so that ammonia nitrogen is mainly with NH 4 + Form exist；(2) pretreated electroplating wastewater constant temperature constant speed under microwave radiation passes through modified alta-mud particle layers；(3) the modified alta-mud particle layers of adsorption saturation are regenerated using diluted acid.This hair is using modified alta-mud as adsorbent, compared to traditional activated carbon, zeolite adsorbents, capacity and better choice with bigger；Using microwave radiation, adsorption process can be promoted, and water quality is not strict with；Using regeneration means, bentonite can be caused to recover adsorption capacity completely, and ammonia nitrogen concentration is high in regenerated liquid, and recoverable, avoids secondary pollution. |
