以降低纯碱蒸氨废液浊度,满足灌注太阳池要求为目的,采用自然沉降和加絮凝剂的方法,进行了降低蒸氨废液浊度的试验研究.结果表明:蒸氨废液中含有CaSO4 · 2H2 O,CaCO3,Mg( OH) 2等水不溶物,是造成浊度高的主要原因;自然沉降速度较慢,添加硫酸铝钾絮凝剂,能够有效缩短沉降时间.

To reduce turbidity of the evaporated waste ammonia liquid of soda and meet the require-ment for pouring into solar pond,we conducted the lower steamed ammonia liquid turbidity test by adding flocculants and natural sedimentation.The results showed that the steamed ammonia waste liquid contained CaSO4· 2H2O,CaCO3,Mg (OH)2, which are the main causes of the high turbidi-ty.Compared to slow natural sedimentation rate,adding aluminium potassium sulfate flocculant,can effectively improve the sedimentation rate and shorten the settling time.
