Fenton深度处理工程应用的技术经济性分析

Abstract:Thetreatmentperformanceandcostofa“Fenton/flocculation”processwereanalyzedbasedontheoperationdataofawastewatertreatmentplantofalargepulpandpaperenterprise.Theresultsshowthattheoptimallevel(TAL-3.84%)oftheeffluentCODis43mg/l,andtheguaranteedvalue(TAL-95%)56mg/lwhentreatedbyflocculation/Fentonprocess,whichcanmeettheintegratedwaterpollutantdischargestandardforHaiheriverbasin,inShandongProvince.Theoptimalvalue(TAL-3.84%)andtheguaranteedvalue(TAL-95%)ofCODremovalratewere88.3%and83.7%,respectively.Averagecostoftheadvancedprocesswas1.46yuan/m3,andthecostrangedfrom1.211.71yuan/m3,withthecostofchemicalsaccountingfor60%.Keywords:pulpandpapermakingwastewater;advancedtreatment;flocculation;FentonTechnicalandeconomicanalysisonflocculation/Technicalandeconomicanalysisonflocculation/FentonprocessforadvancedtreatmentofpulpingandFentonprocessforadvancedtreatmentofpulpingandpapermakingwastewaterpapermakingwastewaterLIUJin-kai1,SHIXiao-lei2,HUHong-ying1,2(1.SteteEnvironmentalProtectionKeyLaboratoryofMicroorganismApplicationandRiskControl,GraduateSchoolatShenzhen,TsinghuaUniversity,Shenzhen518055,China;2.StateKeyJointLaboratoryofEnvironmentalSimulationandPollutionControl,SchoolofEnvironment,TsinghuaUniversity,Beijing100084,China)TECHNOLOGY1022.12.2114171411511611711DPE!nh0mන೺؜຤৊຤31240402312406023124080231240:0ิࣅ؜຤ण຤׾ྃ຤ऐݝْܾקۏ׾ᅃْקۏ׾ݒᆌ׾ౄէྔሏಇ຤ݭ໗็ࣨॾQBNI3P3GfTP5Bm3)TP5*4࿫ౄ౪໫׾TECHNOLOGY11Jun.,2014Vol.35,No.12ChinaPulp&PaperIndustry3431240402312406023124080231240:021213141516171TT!nh0mන೺৊຤؜຤ᄱव72/12&ഄ໱4/39&ยԢች৹36/33&ۯ૰6/1:&ට߾6/4:&51555963677175798387911213141516171ೕຕDPE!nh0m131517191211؜຤DPE౪܈!nh0mೝ਩ኵǖ5:/7ዐक़ኵǖ5:o295ೕຕેओೕ୲ેओೕ୲!&ೕຕેओೕ୲9192939495969798999::112131415161718191ೕຕඁأ୲!&131517191211ેओೕ୲!&DPEඁأ୲!&!ೝ਩ኵǖ97/87!ዐक़ኵǖ97/12o295TECHNOLOGY124.244.1଼໗୩଼໗ჱཎḅӃມᄟ຤็ࣨݭ໗1/11/31/51/71/92/14562/2๑ᆩଉ!lh0n42/12/32/52/72/93/13/33/512131415161718191ೕຕDž131517191211ેओೕ୲!&ׯԨ!ᇮ0n4ศ܈ت૙ጺׯԨ!ᇮ0n4ೝ਩ኵǖ2/57ዐक़ኵǖ2/58!o295ೕຕેओೕ୲TECHNOLOGY13Jun.,2014Vol.35,No.12ChinaPulp&PaperIndustry
