产品概述
美国Challenge公司的AER-208活性污泥呼吸仪/有氧/厌氧呼吸仪适用于环境及微生物领域，同时也适用于土壤或固体废弃物的评估、堆肥和生物降解物质的研究。
AER-208具有全自动、高精度并实时记录耗氧速率（OUR），比耗氧速率（SOUR），以及微生物产气等各种微量气体产量的实时测量，最多可扩展到24通道同时工作。目前在全球数以百计的环境及微生物研究的实验室中已经成为主要的研究工具。Challenge公司时刻与技术人员保持着密切的沟通，听取研究者的实验需求，以使我们的技术更能从根本上满足用户的需求。
应用领域
·耗氧速率（OUR）
·活性污泥处理过程中耗氧速率设置点的控制
·快速BOD5
·毒性的评估
·评估治疗急性毒性的植物
·废水样品的生物降解试验
·评估营养
·混合废水生物降解动力学
·化学制品固有的生物降解动力学
·土壤及堆肥样品的耗氧量
详细资料
AER-208活性污泥呼吸仪/有氧/厌氧呼吸仪由控制主机，反应器，多通道Flow Cell组成。在做有氧/厌氧试验时，反应器产生的气体流入Flow Cell,在Flow Cell中形成气泡，这些气泡在流过Flow Cell中的毛细管时，激活红外计数器，气泡的数量被记录在与之相连的计算机中，从而得到气体的实时体积曲线和速率。
美国Challenge公司的Flow Cell，采用专利技术，每个Flow Cell均经过标定，使得每个气泡的体积为标准体积，通常为0.05ml左右。毛细管每秒最多允许通过2-3个气泡，最大速率可达500ml/Hr

污泥在厌氧环境中产甲烷量检测方案
uestions often arise as to how much residual biodegradable matter remains in sludges from biological processes after previous treatment has been completed( EPA’s F-bio test). In one case, sludge samples were removed from two facultative lagoons. Tests were conducted to determine the methane potential remaining in the sludges and to determine if the sludges were suitable for land spreading. Samples of the sludge containing 20.5 and 22.7 g VSS were transferred to respective reaction vessels and methane production was measured over a period of 18 days. Methane production ranged from 120 mL in one sample to 160 in the second sample as shown in the Figure below. The gas production rate was high for only about 2 days and then leveled off to a rate of about 4 mL/day. The COD conversion equivalent of the produced gas was only about 0.3 to 0.4 g per sample, thereby representing VSS conversions of 1.47 and 1.76 %. The sludge was then deemed to be suitable for land application without further treatment. 微生物降解呼吸仪链接：http://www.instrument.com.cn/netshow/SH101516/C121937.htm#
