摘　　要：DQ催化剂母液水解液进行稀释,使HCl含量<20%,然后进行精馏,得到纯度约为86%～90%的乙醇,氯化氢浓度低于20%的盐酸,氯化氢浓度约20%的盐酸,釜底固体主要成分是二氧化钛。实现了催化剂母液水解液的部分回收及再利用,减少了废水处理量,降低了处理成本,同时降低了环境污染。DQ Catalyst mother liquid was diluted.Sending the HCl content less than 20%,then the rectification,to got the ethanol with purity in the scope of 86%~90%,hydrochloric acid with concentration below 20%,hydrochloric acid with concentration closing to 20% and solids of which TiO2 was the main component.Realizing the purpose of hydrolysate recycling,the amount of processed waste water was reduced,the cost was lowered and meanwhile the environment pollution was lessened in a certain sense.
