中文摘要PAGE\*MERGEFORMAT-54-养猪场污水UASB+SBR工艺处理工程设计摘要养殖业污水中富含大量营养物质，若不经处理直接外排入水体，往往会造成水体富营养化。养猪废水的特点是排放集中、水力冲击负荷强、有机质浓度高、水解酸化快、沉淀性能好。本设计采用UASB+SBR处理工艺，该工艺优点在于艺对有机物、悬浮物、氮和总磷均有很好的去除效果。废水首先进入调节池,去除大部分悬浮物和少量有机物，出水流入集水井，通过泵输送到UASB反应器，大部分有机物被降解，并产生沼气。UASB反应器出水进入SBR反应器进行后续处理，部分有机物和大部分NH3-N被降解。由于SBR反应器出水SS、COD还较高，影响出水水质，因此通过氧化塘作进一步处理，以满足达标排放要求。废水经处理后达到《畜禽养殖业污染物排放标准》（GB18596-2001）排放标准，本设计采用的工艺可达到预期的处理效果。关键词：养猪场废水；有机废水；UASB；SBR；氧化塘英文摘要AbstractAlargenumberofaquaculturewastewaterrichinnutrients,ifnottreateddirectlydischargedintowaterbodiesoutsidewilloftenresultineutrophication.Emissionsfromswinewastewaterischaracterizedbyaconcentrationofstronghydraulicshockloads,highconcentrationsoforganicmatter,hydrolysisacidificationrapidsedimentationperformance.ThisdesignusesUASB+SBRtreatmentprocess,theprocessadvantagesofArtsoftheorganicmatter,suspendedsolids,nitrogenandphosphorusremovalwereverygood.First,adjustthepoolwatertoenter,removemostsuspendedsolidsandasmallamountoforganicmatter,waterwellsintothecollection,bypumpingtotheUASBreactor,mostoftheorganicmatterisdegraded,andproducemethane.UASBreactoreffluentintotheSBRreactorforsubsequentprocessing,partoftheorganicmatterandmostoftheNH3-Ndegradation.SBRreactoreffluentasSS,CODisalsohigh,affectingwaterquality,sobyoxidationpondforfurtherprocessingtomeetthedischargestandardsrequirements.Thetreatedwastewatertoachieve"emissionstandardsforlivestockandpoultrybreedingindustry"(GB18596-2001)emissionstandards,thedesignprocesscanbeusedtoachievethedesiredtreatmenteffect.Keywords:Piggerywastewater.；Organicwaste；USAB；SBR；Oxidationpond目录目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc295167705"摘要PAGEREF_Toc295167705\hiHYPERLINK\l"_Toc295167706"AbstractPAGEREF_Toc295167706\hiiHYPERLINK\l"_Toc295167707"目录PAGEREF_Toc295167707\hiiiHYPERLINK\l"_Toc295167708"第一章前言1HYPERLINK\l"_Toc295167709"1.1毕业设计课题及研究目的意义1HYPERLINK\l"_Toc295167710"1.1.1课题的意义1HYPERLINK\l"_Toc295167711"1.1.2课题研究的目的2HYPERLINK\l"_Toc295167712"1.2国内外养殖业
