                    强化混凝工艺对气田泡排液的处理分析

                    时间:2018-01-15 来源:山西建筑 作者:任聪,苗群 本文字数:3168字

                      摘    要: 星云棋牌官网下载选用了强化混凝工艺对气田泡排液进行预处理实验研究, 采取增加曝气流程以及改变药剂添加方式的方法, 对混凝工艺进行优化改进实验。结果表明, 增加曝气流程和分点加药联合的方式是处理气田泡排液的最优强化混凝工艺, 不仅可以提升混凝效率, 还能有效去除泡排液中的大量悬浮物、COD、油类及溶解性固体等主要污染物质。该研究成果能够为泡排液及类似油气田废水的预处理提供一些参考。

                      Abstract: In this paper, the enhanced coagulation process was used to pretreat the foam fracturing flowback fluid in gas field. Methods of increasing aeration process and changing the way of adding chemicals are adopted, optimizing and improving the coagulation process. The results show that, increasing the aeration process with change the adding chemical agentia point is the best enhanced coagulation processes for treating foam fracturing flowback fluid in gas field. It can not only enhance coagulation efficiency, it can also effectively remove a large number major pollutants as suspended solids, chemical oxygen demand, oil and soluble solids in effluent. The research results can provide some reference for the pretreatment of foam fracturing flowback fluid in gas field and similar oil-gas field wastewater.
