摘要
通过环氧化合物胺化的方法制得的阳离子型聚胺类化合物,可以作为废水处理的混凝剂或助凝剂使用,对于降低工业废水的悬浮物和色度效果显著。若与一定量的无机絮凝剂,如三价铁盐或三价铝盐共同作用,则效果更佳。聚胺类化合物曾用来处理造纸、制革、印染等工业废水,结果令人满意。
Cationic polyamines obtained by amination of epoxy compounds may be used as flocculating agents or flocculant aids for the treatment of certain industrial wastewater. It can be utilized effectively for the removal of suspended solids and colours, particulary when inorganic flocculant, for example salts of Fe (Ⅱ) or Al (Ⅲ), is added simultaneously. Polyamines have been applied to treat wastewaters from paper making, tanning and textile printing-dying with satisfactory results
