以果冻为主的食品生产废水处理工程实例_胡军周以果冻为主的食品生产废水处理工程实例胡军周1,李洪涛1,杨明友2(1.河南省科学院地理研究所,河南郑州450052;2.新乡市蓝海环境工程有限公司,河南新乡453000)[摘要]根据以果冻为主的食品生产废水的特点,采用“预处理+气浮+厌氧+好氧”的综合工艺进行处理。运行结果表明,该工艺处理效果良好,运行稳定,系统总COD去除率达97%,BOD5总去除率达98.5%,SS总去除率达94.9%,动植物油总去除率达93.4%,氨氮总去除率达85.7%。出水各项指标均优于《污水综合排放标准》(GB8978—1996)中二级标准的要求。[关键词]果冻食品废水;预处理;气浮;厌氧;好氧[中图分类号]X703.1[文献标识码]B[文章编号]1005-829X(2014)07-0081-04Engineeringexampleofthetreatmentofwastewaterfromfood(mainlyjelly)productionHuJunzhou1,LiHongtao1,YangMingyou2(1.InstituteofGeographicalSciences,HenanAcademyofSciences,Zhengzhou450052,China;2.XinxiangBlueOceanEnvironmentalEngineeringCo.,Ltd.,Xinxiang453000,China)Abstract:Accordingtothecharacteristicsofwastewaterfromfood(mainlyjelly)production,thecombinedprocess“Pretreatment+Airfioatation+Anaerobic+Aerobic”hasbeenusedforitstreatment.Therunningresultsshowthattheprocesstreatmenteffectivenessisgood,andrunsstably.ThetotalremovingrateofCODis97%,totalremovingrateofBOD598.5%,totalremovingrateofSS94.9%,totalremovingrateofanimalandplantoil
