题目：A/O工艺解决石化污水设计院系：专业：班级：学生姓名：指引教师：论文提交日期：年月日论文答辩日期：年月日摘要本设计题目是设计一座化工污水解决厂。该污水解决厂位于某石油化工厂内，其解决污水量为3.6万吨/天，初始BOD5浓度为350mg/L,SS浓度为450mg/L。本设计采用工艺为A/O生物除磷系统，该工艺在污水解决方面属较为新颖办法，技术较为成熟，较之普通污水解决工艺有其不可比拟长处，在经济和技术上均有明显优势。出水指标能达到国家二级排放原则。该工艺流程是：污水经粗格栅去除大体积杂质，再通过调节池对初进污水进行整流和均质，由细格栅进入隔油池，重要是去除悬浮于污水中油类物质。接着污水进入厌氧池，可吸取去除一某些有机物，并释放出大量磷，设计为矩形反映池。污水又进入好氧池，使废水中有机物得到好氧降解，同步污泥将大量摄取废水中磷。设计为推流式矩形反映池。再经由配水井流入二沉池排放，二沉池污泥经回流泵房后剩余污泥通过污泥泵打入厌氧池，使得污水中BOD5、SS达标排放。同步，在此污水解决过程中产生污泥量较少，经简朴浓缩池浓缩、脱水后外运。本设计采用可靠安全办法，合理布局，美化环境，把污水解决厂建成一种花园式厂区。核心词：厌氧好氧A/O生物除磷系统Abstract:Thetitleofthisthesisistodesignasmallmunicipalsewagetreatmentplant.Thisplantliesinthesuburbofsomedistrict.Itcandispose36,000cubesewageeveryday.TheprimaryconcentrationofBOD5andSSis400mg/Land350mg/L.Theprocessofthisthesisisman-madewetlandtreatmentsystem，whichisanewpathwayinthesewagetreatment.Thetechniqueofthisprocessisoffercomparativeadvantagesineconomicandtechnology.Thequalityofdisposedeffluentisuptothesecondclassofnationalstandard.Thefirststepofthisprocessisscreening，whichremovesbig-sizedtrash.Thenthecomminutingdevicecommutateandshredthesolidsinthesewageandthewasteflowintotheprimarysettingtankthroughthemeshgrid，Thesewagegothroughthethingrilltotheinitialsinkingpond，atthisstepthesolidsuspensionwhichmayprecipitateinthesewageareremoved.Accordingtorequestandthiscraftcharacteristicwhichdesignsneeded，takethespoketoflowthetypesedimentationpond.Afterwardsthesewageenterstiresoftheoxygenpond，mayabsorbremovespartoforganicmatters，andreleasesthemassivephosphorus.Theinteriordesignofthetiresoftheoxygenpondistherectangle.Whenthesewageenterstheoxygenpond,theorganicmatterinthewastewateraredegradedbythegoodoxygen，simultaneouslythesludgemassivelywillabsorbthephosphorusinthewastewater.Respondedtheponddesignforpushspreadthetyperectangleresponsepond，thedesignspecificationisthesameastheinitiallysinkingthepond.Twosinkthedirtymireofthepondwaspassedbydirtymireinsurplusinempressinpumphouseinrefluxthedirtymirepumpbeatsintolacktokeepthepond，atwhichtheBOD5andSSofthewaste
