预氧化加复合絮凝剂处理高温石油废水

水污染治理预氧化加复合絮凝剂处理高温石油废水曲久辉　雷鹏举　栾兆坤　田宝珍　于忱非(中国科学院生态环境研究中心环境水化学国家重点实验室,北京100085)摘要　采用自制PCM2复合药剂处理含油和高分散细微悬浮物石油废水。研究证明,使用现有单一的有机或无机絮凝剂无法达到对这种具有特殊水质的石油废水的期望处理效果。在被处理水为室温的条件下,适量的PCM2不仅有效去除水中的油,而且可以将难处理的细微悬浮物含量降到较低。在高温处理条件下,采取预氧化加PCM2可以显著提高对水中油尤其是细微悬浮物的去除效率,处理后水质可以达到油田回注标准。关键词　复合絮凝剂　预氧化　石油废水HIGHTEMPERATUREOILWASTEWATERTREATMENTBYCOMPOUNDFLOCCULANTWITHPREOXIDATIONQuJiuhuiLeiPengjuLuanZhaokunTianBaozhenYuZhenfei(StatekeyLaboratoryofEnvironmentalAquaticChemisty,ResearchCenterforECO2EnvironmentalSciences,ChensesAcademyofSciences,Beijing100085)ABSTRACT　Thispaperstudiesthetreatmentofwastewaterwithoilandhighdiffusedmicro2suspend2edcolloidsusinganewcompoundflocculantPCM2madeinourlaboratory.Theexperimentshowedthatthiskindofwastewatercouldnotbetreatedefficientlybytheordinaryandsingleflocculant.Thecom2poundflocculantPCM2howevercouldmeettherequirementoftrreatment.AsuitablecontentofPCM2wasnotonlyabletoremoveoilbutalsothemicro2suspendedcolloidsfromwastewaterefficientlywhichcanhardlyberemovedbythenormalmet
