屠宰场废水处理毕业设计样本.doc

摘要本设计为湖北省某屠宰场废水解决设计。屠宰场在运营生产过程中会产生大量具有高浓度有机物废水，重要来自于各种牧畜、禽类、鱼类宰杀和加工，是国内最大有机污染源之一。该屠宰废水解决厂解决水量为1000m3/d，污水中各项污染物指标为BOD为1000mg/L，COD为mg/L,NH3-N为30mg/L以及SS为1500mg/L。由于该废水COD和BOD浓度较大，因此咱们规定解决后污水达到国家一级排放原则即：BOD≤25mg/L，COD≤100mg/L，NH3-N≤15，SS≤70mg/L。经分析可知该屠宰场废水重要包括是易沉淀悬浮物和无机物和易生化降解有机物，因此咱们可以采用物理解决和生物解决相结合方式来进行污水净化。一方面采用物理解决来去除污水中容易沉淀悬浮物和无机物，然后采用水解酸化-SBR工艺来去除污水中有机物。具备投资和解决成本低廉，工艺简朴和管理以便等诸多方面长处。核心字：屠宰场废水；水解酸化；SBR工艺ABSTRACTTheslaughterhousewastewateristreatmentinthisdesigninHubeiProvince.Alargeamountofwastewatercontaininghighconcentrationoforganicmatterisproduceinrunningofslaughterhouse，TheslaughterhouseWastewaterisoneofthecountry'slargestorganicpollutionsources，whichmaincomefromslaughteringlivestockbreeding﹑poultry﹑fishslaughterprocessing.Thewaterwhichneedstotreatmentintheslaughterhousewastewatertreatmentplantis1800m3/d.Varioustargetintherawwastewateris：theconcentrationofBODis1000mg/L，theconcentrationofCODis1800mg/L，theconcentrationofSSis800mg/L.fortheslaughterhousewastewater’sCODandBODishigh,soitrequesttheslaughterhousewastewatertomeetthenationalfirstdischargestandardsafterprocessing：BOD≤25mg/L﹑COD≤100mg/L﹑SS≤70mg/L﹑NH3-N≤15mg/L.Aftertheanalysis,thequalityofthisprocessingwaterbelongstothewastewaterthateasysedimentationofsuspendedsolidsandeasybiochemicaldegradationoforganicmatter.Sowecanadoptingthecombinationofphysicaltreatmentandbiologicaltreatmentmethodstodealwiththewastewater.Firstly，wecanadoptingphysicaltreatmenttoremovetheeasysedimentationofsuspendedsolidsinwastewater，afterthat，usetheprocessofhydrolyticacidification-SBRtoremovetheorganicmatterinwastewater.Hastheadvantagesoflowprocessingcost，simpleprocess，easytomanagementandsoon.Keywords：slaughterhousewastewater；hydrolyticacidification；SBRtechnology目录TOC\o"1-3"\h\uHYPERLINK\l_Toc6382摘要PAGEREF_Toc6382IHYPERLINK\l_Toc21415ABSTRACTPAGEREF_Toc21415IIHYPERLINK\l_Toc31585前言PAGEREF_Toc315851HYPERLINK\l_Toc7220第一章概论PAGEREF_Toc72202HYPERLINK\l_Toc211531.1设计任务PAGEREF_Toc211532HYPERLINK\l_Toc4751.
