| Research Abstract |
In this study, low-cost, low environmental impact, possible acquisition of energy by methane recovery , focusing on anaerobic treatment. And yet, does not require the formation of granular sludge and can treat wastewater with high inhibitory, using the anaerobic reactor, examined adaptability of anaerobic treatment for water-miscible cutting oil wastewater. In the experiment, about 20 times diluted with tap-water soluble cutting oil wastewater was fed, performed more than 240 days of continuous water flow experiments. By 200 days, the amount of waste water is fed on 5L/day, CODCr removal rate stabilized at about 40 percent. Thereafter, Added nutrients and halfed the load. CODCr removal rate was about 50 percent, but good treatment quality were not obtained. For bacteria in the sludge adhering to the sponge microbial community structure were analyzed, acetogenic bacteria and oil degrading bacteria was confirmed. Suggested that the adaptability of anaerobic treatment to oil wastewater.
