华东交通大学毕业设计1涪陵区江南片区污水处理工程设计摘要涪陵区江南片区污水处理厂,近期日处理水量为20万吨,远期日处理水量为25万吨。处理水主要对象是城市生活污水。生活污水中主要含有有机物、N、P。出水水质要达到一级标准B标准。本设计主要考虑提高N、P的去处率。污水厂占地面积41万平方米,包括远期预留。。。。本设计主体工艺采用氧化沟——Carrousel2000型,氧化沟前设置厌氧池。整体工艺流程为::采用氧化沟不设初沉池,处理设施大大简化。氧化沟具有传统活性污泥法的特点,有机物去除率高,也具有脱氮功能。设置前置厌氧池提高释磷菌的释磷效果,从而提高磷的去除率。这样有机物、N、P的处理均满足要求。处理后的水经紫外线消毒后直接排入水体。剩余污泥经过气浮浓缩、脱水后泥饼外运或当作肥料。关键词:氧化沟;厌氧池;N;P吴帆:涪陵区江南片区污水处理厂2FulingDistrictJiangnanDistrictofsewagetreatmentworksdesignAbstractJiangnanDistrictofFulingDistrict,asewagetreatmentplant,Recentprocessingcapacityof200,000tons,thelong-termprocessingcapacityof250,,N,,,000squaremeters,--:OxidationDitchnoprimarysettlingtank,,,,N,,:OxidationDitch;Anaerobicpond;N;P华东交通大学毕业设计1目录第一部分设计说明书1总论·····················································································································································································································································································································································································
