Biodegradation of Major Pollutants in Yeast Wastewater by Using Immobilized Micro-Aerobic Microorganism Technology

Abstract:

In order to provide an effective and economic method for the yeast wastewater′s treatment, this study taken yeast wastewater as objection, and applied immobilized micro-aerobic microorganism technology into yeast wastewater′s treatment, then explored the degradation effect of major pollutants in yeast wastewater. The immobilized carrier was analyzed by scanning electron microscope (SEM) and Fourier transform infrared spectrometer (FTIR), and dominant species in immobilized carrier were identified. The results showed that immobilized carrier was a composite carrier with porous structure, and removal rate of chemical oxygen demand (COD), ammonia nitrogen (NH₃-N), total nitrogen (TN) and total organic carbon (TOC) of yeast wastewater by using the immobilized micro-aerobic microorganism technology were 71.1%, 99.7%, 61.4% and 67.0%, respectively. Moreover, the dominant bacteria which attached in the carrier included Sphingomonas paucimobilis, Pseudomonas putida, Acinetobacter lwoffii and Pseudomonas stutzeri.
