Experimental Study on Separating Aviation Kerosene from Oily Wastewater by Using Microwave Radiation

Abstract

According to the characteristics of oily wastewater, microwave technology was introduced to separate aviation kerosene from oily water. The uniform design with mixed level including main influence factors was applied to design the experimental scheme. The influence factors such as oil content, radiation power, radiation time length and standing time after radiation were considered. The influence of these factors on separation of oil from oily water was investigated through experiments, and deoiling amount formula was regressed. The results show that these four factors are positive to the separation of oily wastewater, of which oil content is the most important to the separation, the product of radiation power and radiation time is the second, and standing time is the third. Treatment of oily wastewater using microwave benefits to the efficiency of discharging sewage and the recovery of oil product to meet the relative standards.
