The Development and Application of Non-ammonium Deliming Agent

This paper developed the new non-ammonium deliming agents which made from the acid salt and the weak acid or the acid salt and the weak acid salt.And these materials were compared with the market non-ammonium deliming agent and the ammonium chloride.The experiments proved that the new non-ammonium deliming agents were safe,had a good deliming performance and could reduce the content of the ammonia nitrogen and COD in the waste water.
