摘　　要：常用于天然气钻井废水处理的絮凝剂有无机物型和有机高分子型,无机絮凝剂投加量大、产生污泥多;有机高分子絮凝剂,选择絮凝剂的价格较贵,且单独使用效果不佳。因此针对天然气钻井废水水质,需要寻找一种价廉物美、无污染、制用方便,效果好的绿色絮凝剂。经实验合成了一系列磷酸酯胺盐表面活性剂,其反应的原料、过程和产物都较为绿色化。此磷酸酯胺盐是利用从植物中提取的类葡萄糖结构的无毒天然化工产品为原料制成的,具有分子量小、易生物降解的优点。以磷酸酯胺盐作为絮凝剂,与Al2(SO4)3溶液复配使用,在对川东天然气钻井废水的絮凝处理实验中获到一定效果。其结构兼具对金属缓蚀的功效,是一种多功能的绿色表面活性剂。The experiment synthesized a series phosphoric-acid-ester-amine surfactant. The material, process and products of this experiment are all green. The phosphoric-acid-ester-amine was synthesized by innocuous natural chemically product whose molecular configuration are similar with dextrose. It has small molecular weight,so it is easy to be decomposed. The experiment used the phosphoric-acid-ester-amine as a flocculant, and cooperated with liquor of Al2(SO4)3 to dispose waste water of nature gas well in east of Sichuan,and attained available result. Its molecular also has the effect of rust-inhibitor,it is a multifunctional green surfactant.
