摘　　要：煤层气田产出水经过反渗透处理后的浓水中含有较高质量浓度的Li+,本文以山西某煤层气田产出水经反渗透处理后的浓水为样本进行配水提Li+试验,结果表明:控制Al/Li(物质的量比)为3.3,Na/Al(物质的量比)为2.6,同时滴加铝盐溶液和NaOH溶液并不断搅拌,在恒温55℃下反应120min后,Li+沉淀率最高,为88.71%。The water produced with coal-bed methane concen-trated water under RO treatment contains Li^＋ of high concentra-tion. Tests on extracting Li^＋ by preparation of water based on concentrated water of coal-bed methane produced water treated by RO showed that the highest Li^＋ precipitation rate of 88.71% could be obtained by controlling AI/Li = 3. 3, Na/Al = 2. 6, adding and stirring constantly Al^3＋ solution and NaOH solution under the conditions of constant temperature 55 ℃.
