本科毕业设计（论文）250吨/天印染污泥干化及焚烧处理工艺设计学院环境科学与工程专业环境工程设计总说明随着印染行业蓬勃发展，我国对印染废水处理力度在不断加大，每天处理污水产生相应大量污泥,污泥量日益增加，产生的污泥的组成成分日益复杂，如处理不当，必然会对自然环境造成二次污染，存在比较严重的环境安全隐患。本设计要求处理250吨/天的印染污泥，原污泥为经过板框压滤机压滤过的含水率约82%的湿污泥。针对印染污泥的特点，结合国外处理污泥的成功经验以及国内对印染污泥的成熟工艺，决定选用先干化后焚烧的工艺。该工艺具有工艺成熟、稳定、节能、占地少、效率高等优点。基本工艺流程为：储泥室→回转烘干机→制砖机→焚烧炉→炉渣、煤灰等回收。本设计所用的主要设备有Ф3.0×28m型回转烘干机、AB-200型焚烧炉、QTY8-15型砌块成型机、ppw64-7脉冲布袋收尘器、Ф1.5×16m脱硫塔、LXT-5型活性炭吸附塔。工程总投资为1305万元，每年的总运行费用为1264.34万元。关键词：印染污泥干化焚烧回收利用DesignilluminateWithprintinganddyeingindustryvigorousdevelopment,theprintinganddyeingwastewatertreatmentingrowing,everydaytoproducelargeamountsofsewagesludge,thesludgequantityincreasing,thecomponentsofsludgeproducedbytheincreasinglycomplex,suchasimproperhandling,isboundtocausesecondarypollutiontothenaturalenvironment,thereareseriousenvironmentalsafetyhiddentrouble.Inthisdesign,projectsrequiredtotreat250tons/dayprintinganddyeingsludge.Moisturecontentoftheoriginalsludge，whichhasbeenpressedbytheframefilter，isapproximately82%.Aimingatthecharacteristicofdyeingsludge,andinthelightofthesuccessfulexperienceofexternaltreatmentofdyeingsludgeandmaturetechnologyofinternaltreatmentofthat,weselectdryingandincinerationtechnology.Suchatechnologyhastheadvantageofmature,stable,energy-saving,smallfootprintandhighefficiency.Basicprocessis:Storedmudroom→Rotarydryerbrickmachine→Incineratorslag→Ashandotherrecycled.ThemainequipmentusedinthedesignisФ3.0×28mRotaryDryer,AB-200typeincinerator,QTY8-15blockmakingmachine,ppw64-7Pulsebagfilter,Ф1.5×16mdesulfurizationtower,LXT-5-typeactivatedcarbonadsorptiontower.Thetotalinvestmentis13.05millionyuan,thetotalannualoperatingcostis12,643,400yuanKeywords：dyeingsludgemummificationincinerationrecycle目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc358323397"1概述PAGEREF_Toc358323397\h1HYPERLINK\l"_Toc358323398"1.1设计名称PAGEREF_Toc358323398\h1HYPERLINK\l"_Toc358323399"1.2设计要求PAGEREF_Toc358323399\h1HYPERLINK\l"_Toc358323400"1.3处理处置的一般要求PAGEREF_Toc358323400\h1
