　　内容简介：
　　讲座一：
　　Biological treatment systems have been used to treat municipal wastewater for at least 50 years. These systems are not used often to treat industrial waste due to misconceptions about the processes and organisms involved. This presentation will summarize the basics of biological treatment systems and present a specific example of the use of an anaerobic system to convert the energy in the organic material in winery wastewater to methane gas that can be used as a fuel for heating or power generation.
　　讲座二：
　　Nitrate contamination of groundwater from the overuse of fertilizer in agriculture or from improper disposal of municipal or industrial waste is a problem worldwide. Perchlorate is an industrial contaminant used in military ordinance, fireworks, and automobile air bags. It can be found in groundwater near production plants and near disposal facilities.
　　High intake of nitrate causes different health issues, most importantly methemoglobinemia, a condition where the blood cannot carry oxygen. To limit the risk to human health, the maximum acceptable concentration of nitrate in drinking water is set to be 45 mg /L as nitrate by USEPA. Perchlorate is known to inhibit the production of hormones from the thyroid gland. This affects all metabolic processes. 
　　This research presentation summarizes 15 years of research in the development of a technology to remove nitrate and perchlorate from contaminated groundwater. The technology combines the use of ion exchange processes to remove perchlorate and nitrate from drinking water with a biological treatment step to allow reuse of regenerant brine or direct regeneration of the resin. The presentation will include microbiological investigations as well as mathematical modeling of the chemical and biological reactions.
