ABSTRACT

Organic carbon source deficiency is still one of the core problems for nutrient removal in an activated sludge system. When microorganisms in this system cultivated through alternative famine/feast period, a metabolic response of microorganisms can be induced to accumulate / decompose cell energy storage polymers with the existence of external carbon source. Based upon this fact, the applicant intends to couple the removal process of nitrogen with the removal of organic pollutants, during which some parts of organic carbon can be converted and accumulated in the form of cell polymers, subsequently, those cell polymers were used as electron donor for denitrification process, thus realize a denitrification process driven by cell polymers. The process could be expected to solve the problem of the lack of carbon source for biological denitrification, and meanwhile could reduce the energy consumption as some of organic matters has been converted, which was of great application potential. To start some basic research concerning the mentioned above, an integration technology of multi-disciplinary theory and analysis methods for wastewater treatment engineering, microbiology and biochemistry might be employed, and our main objectivies are to explore the formation and types of cell polymer related to different organic More... »
