可溶性油类和溶解性有机物对砂加载混凝沉淀处理高悬浮矿井水效果的影响

Effect of Soluble Oils and Dissolved Organic Matters on Coagulation Treatment of High Suspended Mine Drainage

矿井水中可溶性油类和溶解性有机物含量对石英砂加载混凝沉淀效果的影响很少有系统的研究,影响机制也不清晰。为此,选用石英砂加载混凝处理高悬浮矿井水为研究对象,分析矿井水中乳化油、浓缩液、腐殖酸(humic acid,HA)、富里酸(fulvic acid,FA)和L-色氨酸(L-tryptophan,LA)含量对石英砂加载混凝处理高悬浮物矿井水效率的影响。分析结果表明:矿井水中乳化油、浓缩液和过量的HA含量不利于加载混凝沉淀处理的效率和沉淀速率。HA、LA和适量的FA含量并不能影响加载混凝沉淀处理高悬浮物矿井水的效率和沉降速率。响应面分析结果表明乳化油和浓缩液的浓度变化对砂加载混凝沉淀效率和过程的影响较大,而HA、FA和LA的浓度变化则对其影响较小。该结果为进一步认知砂加载混凝处理工艺,提升其处理效率,实现中国煤矿矿井水资源保护和合理化利用具有重要的意义。

Few systematic studies on the effect of content of soluble oils and dissolved organic matters on coagulation treatment of high suspended mine drainage.Therefore,the typical high suspended mine water was selected to analyze the effect of content of emulsified oil,concentrated liquid,HA(humic acid),FA(fulvic acid)and LA(L-tryptophan)on the efficiency of high suspended matter mine water treated by loading coagulation treatment with sand.The results show that emulsified oil,concentrated liquid,and excess FA were harmful for the efficiency and rate of loading coagulation treatment with sand.Whereas,the effect of HA,LA and lower FA content effect can be ignored.The results can effectively improve the operation technology of the loading coagulation with sand,realize the protection and rationalization of coal mine water resources.
