Reclaimed Systems Survey: Operational Impact on Organic Carbon and Biostability 回收系统调查:操作对有机碳和生物稳定性的影响
发布日期: 2009-11-01
本powerpoint演示文稿首先简要概述了经处理废水的再利用和再利用应用。概述了有机碳和再生的影响,以及研究目标,包括:调查处理过的废水-关注再生 21个污水样本中的驱动因素和处理过程; 在4个设施进行为期12个月的密集调查——处理、储存 以及分布对微生物生长关键驱动因素的影响;和 消毒研究——在4个设施部署管道回路进行测试 再生驱动菌和微生物的消毒策略 密度。实验方法包括可同化有机碳(AOC)生物发光。本文介绍了废水调查的结果以及消毒研究的结果。结论表明:AOC的快速生物发光法是成功的 测量再生水的生物稳定性;天然有机物的含量对环境产生了巨大的影响 再生水的微生物学;膜生物反应器可有效降低AOC和BDOC水平, 确认出水水质良好——数据表明,其他 技术可以用来生产类似质量的产品;活性污泥技术——能够产生废水 生物降解有机碳含量低;露天储存和消毒可提高AOC和BDOC水平;厌氧条件下,硫化物的产生。 包括数字。
This powerpoint presentation begins by presenting a brief overview of the reuse of treated wastewater and reuse applications. The impact of organic carbon and regrowth is outlined, along with study objectives that include: survey treated wastewater effluents - focus on regrowth drivers and treatment process in 21 effluent samples; intensive 12-month survey at 4 facilities - treatment, storage and distribution impacts on key drivers of microbial growth; and, disinfection study - deploy pipe loops at 4 facilities to test disinfection strategies on regrowth drivers and microbial densities. Experimental methods included assimilable organic carbon (AOC) bioluminescence. Results of the wastewater survey are presented, along with results of disinfection studies. Conclusions indicate the following: the rapid bioluminescence method for AOC was successful for measuring the biostability of reclaimed waters; the levels of natural organic matter had a dramatic impact on the microbiology of reclaimed water; membrane bioreactors effectively reduce AOC and BDOC levels, confirmed high quality of effluent - data suggests that other technologies can be operated to produce similar quality; activated sludge technology - capable of producing effluent with low levels of biodegradable organic carbon; open storage and disinfection increase AOC and BDOC levels; and, anaerobic conditions, sulfide production. Includes figures.
