三、名词解释8rf★济宁成人高考报名0537-2229526

1答:由于某种因素的改变活性污泥质量变轻、膨大、沉降性能恶化,SVI不断升高,不能在二沉池内进行正常泥水分离,二沉池污泥面不断上升,最终导致污泥流失,影响系统正常运行的现象。8rf★济宁成人高考报名0537-2229526

2答:也就是沉淀池的表面水力 负荷,沉淀池单位时间单位面积所承受的水量。8rf★济宁成人高考报名0537-2229526

5、指曝气池内每公斤活性污泥单位时间负担的五日生化需氧量公斤数。其计量单位通常以kg/(kg·d)表示。8rf★济宁成人高考报名0537-2229526

四、简答题8rf★济宁成人高考报名0537-2229526

1微生物的比增长速率就是单位重量微生物(活性污泥)的增殖速率。其单位为时间的倒数。污泥龄是控制曝气池中污泥排放时间的一个工程参数,是微生物从长成到排出曝气池的时间,和微生物的比增长率不同,但是根据其定义,其与污泥龄成倒数关系。8rf★济宁成人高考报名0537-2229526

2:是与活性污泥法并列的一类废水好氧生物处理技术,是一种固定膜法,是土壤自净过程的人工化和强化; 8rf★济宁成人高考报名0537-2229526

主要类别: 生物滤池普通生物滤池高负荷生物滤池塔式生物滤池;生物转盘;生物流化床;生物接触氧化8rf★济宁成人高考报名0537-2229526

3在有氧的情况下,由于微生物的或可降解有机物稳定化所需的氧量,称为生化需氧量, BOD5通常是在20oC下培养5天检查溶解氧的损失量。8rf★济宁成人高考报名0537-2229526

BOD2020度、20天的生化需氧量(BOD20)可作为第一阶段的生化需氧量; 8rf★济宁成人高考报名0537-2229526

CODcr当用重铬酸钾作为氧化剂时,硫酸银作为催化剂时,浓硫酸提供酸性环境,水中有机物几乎可以全部(约为9095%左右)被氧化。这时所剩的耗氧量称为重铬酸钾耗氧量或称化学需氧量。8rf★济宁成人高考报名0537-2229526

TOD表示高温下燃烧化合物所耗去的氧量;8rf★济宁成人高考报名0537-2229526

四者之间数值大小排列TODCODCrBOD20BOD58rf★济宁成人高考报名0537-2229526

4、空气在加压条件下溶于水中,再使压力降至常压,把溶解的过饱和空气以微气泡的形式释放出来。8rf★济宁成人高考报名0537-2229526

基本工艺:全溶气流程,部分溶气流程和回流加压容器流程。8rf★济宁成人高考报名0537-2229526
溶气方式:水泵吸水管吸气溶气方式,水泵压水管射流溶气方式和水泵空压机溶气方式。8rf★济宁成人高考报名0537-2229526

5隔板反应池的隔板间距是变化的,为了简化,一般分成3~4段,每段内的隔板间距不再变化,各段内的流速不同,所以拐弯处的水头损失3v2/2g也应分段计算。8rf★济宁成人高考报名0537-2229526

五、计算题8rf★济宁成人高考报名0537-2229526

解:两种污水混合后的BOD5浓度为8rf★济宁成人高考报名0537-2229526
