| description | The circular utilization of Y-type molecular sieve exchange washing water includes the following steps: adding flocculant into molecular sieve exchange washing water and stirring to form clear liquidand solid precipitate; separating the clear liquid from the solid precipitate; making the separated clear liquid pass through cationic exchange resin; and compounding the clear liquid into molecular sieve exchange solution for circular utilization. The said method can reduce the preparation cost of molecular sieve effectively and reduce the amount of drained sewage. |
