一种无害化处理BDO有机废液的方法
摘要：
本发明公开一种无害化处理BDO有机废液的方法，包括以下步骤：(1)将BDO有机废液投料入反应釜，加酸调pH值，蒸馏分离收集轻沸物、水份；(2)将反应底物分离盐和醇液；(3)分离出的盐用有机溶剂洗涤精制；(4)分离盐后的醇液再进行进一步的精馏提取。本发明不仅将BDO有机废液进行处理得到BDO和钠盐产品，更主要的是实现了BDO有机废液的100％无害化和零废物排放处理，同时生产效率可提高5倍以上，一次除盐率达99％以上，本发明方法不用催化剂，简单易行、好操作，更易实现规模化生产，成本更低。
摘要（英）：

The invention discloses a method for harmlessly treating BDO organic waste liquid. The method includes the steps of firstly, adding the BDO organic waste liquid into a reaction kettle, adding acid to regulate pH, and performing distillation separation to collect light end and moisture; secondly, performing salt and alcohol solution separation on reaction substrate; thirdly, washing and refining the separated salt with organic solvent; fourthly, performing further distillation extraction on the alcohol solution after salt separation. The method has the advantages that the BDO organic waste liquid is treated to obtain BDO and sodium salt, 100% harmless and zero waste emission treatment of the BDO organic waste liquid is achieved, production efficiency is increased by more than 5 times, one-step desalting rate reaches more than 99%, and the method which does not use catalysts is simple and practical, easy to operate, easy to achieve large-scale production and low in cost.
