摘要
采用酸式盐和弱酸或弱酸盐开发一种新型的无铵脱灰剂,并与市售无铵脱灰剂、常规铵盐作比较。实验结果表明:该种新型无铵脱灰剂操作安全,具有良好的脱灰效果,在大幅降低废液中氨氮含量的同时不增加COD含量。
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.
