Adsorbent processing waste water is closed, COD value is remarkably decreased in the waste water after processing, and compound adsorbent can significantly remove the phosphorus in sewage
Element, has obvious facilitation to waste water treatment process.For ammonia nitrogen concentration, the effect of adsorbent is little, if
Addition is small on the ammonia nitrogen concentration influence after sewage disposal, can ignore substantially.
