The objective of this joint project between Dr. Gene F. Parkin at the University of Iowa and Dr. Bruce E. Rittmann at the University of Illinois include evaluation of the rate at which soluble metabolic products are produced during anaerobic processes for wastewater treatment, determination of their chelation properties and role in reducing metal toxicity during the respiratory process. A unified conceptual model will be developed and utilized as a basis for evaluation of more rational approaches to design of treatment processes than are now possible be based on effects of solids retention time, metal and substrate loading on metal toxicity to the reaction and nutritional requirements of the methanogenic organisms involved in the treatment process. This is a project that is responsive to recent findings regarding the role played by residual metabolic products and trace metals in anaerobic wastewater treatment. Through this cooperative project, the investigators will coordinate their work utilizing intermediate results to relate results of chemostat research to comparable reactions on fixed biofilms reactors. Results are expected to result in improvements in engineering design of biotreatment processes used for industrial and municipal treatment practice.

爱荷华大学的Gene F. Parkin博士和伊利诺伊大学的Bruce E. Rittmann博士的联合项目的目标包括评估废水处理厌氧过程中产生可溶性代谢产物的速率，测定其螯合特性及在降低呼吸过程中金属毒性中的作用。将开发一个统一的概念模型，并将其作为评价处理过程设计的更合理方法的基础，而不是目前可能根据固体滞留时间的影响进行评价。金属和底物的负荷对反应的金属毒性和处理过程中涉及的产甲烷生物的营养需求。这是一个项目，是响应最近的发现关于作用的残余代谢产物和微量金属在厌氧废水处理。通过这个合作项目，研究人员将协调他们的工作，利用中间结果将趋化剂研究结果与固定生物膜反应器上的可比反应联系起来。研究结果有望改善用于工业和市政处理实践的生物处理工艺的工程设计。
