摘要
对直接耐晒翠蓝GL传统生产工艺中的盐析进行了彻底改革。用两次沉降取代了两次盐析,用少量絮凝剂取代了大量的氯化钠,工业废水的治理也得到了简化。
The production of Direct Light Turquoise GL has thoroughly improved. Double settling is used instead of double salting out, and less flocculant to replace large amounts of common salts required, thus the treatment of the waste is largely simplified.
