我国尤其是北方矿区严重缺水,许多矿区需要开辟新水源,矿井水资 源化是解决矿区水问题的最佳选择,目前矿井水的处理利用率低,有些矿 区利用率 , 较高,但往往未达到饮用水的卫生标准,而且处理成本很高。本 文针对这一现实以及阜新矿区严重缺水的状况,提出了矿井水资源化的最 佳方案、最佳处理方法和处理设施以及最佳工艺流程,实现了“优质水优 用,低质水低用”的原则,并通过实验室的混凝实验研究确定了最佳的药 剂配合和最佳投药量以及最佳PH值,这些研究成果具有一定的理论意义和 实用价值,并且值得推广应用。 关键词:矿井水资源化处理利用方法絮凝实验宁工程技术大学硕士学位报告 ABSTRACT 从值ter15seriousdefieieniesPeeiallyinoureountrynorthminingarea,manyminingarea needopenuPnewWatersource,miningdrainage15ehangedusefulresouree15theoPtimuxn seleetionofsolvingminingwaterProblem,atPresenttherate15lowabouttreatmeniand utilizeminingdrainage,someminingareatherate15high,butofteneannotreaehdrinking watersanitationstandard,eventhoughreaehdrinkingwatersanitationstandard,butthe capital15veryhightreatmeniit,basingontheserealityandtheseriousdefieientwaterstate inFuxinminingarea,inthisP叩erbring即optimumplanand’optimumtreatmentmethod andoPtimumteehnologiealProeessrealizethePrineiPleaboutexeellentqualitywaterandexeellentusefulness,lowqualityWaterandlowusefulness,阴dbyeoagulationexPerimentin thelaboratoryaseertainthatoPtimummedieamenioPerateineoordinationandoPtimum medieationquantityandoPtimumPHvalue,theresearehProvidedWitheertainlytheoretieal meaningandPractiealvalue,anddeservePoPul而zeapPlieation.
