摘要
Abstract
Advanced treatment for coking wastewater was investigated experimentally by A/A/O+MBR combination treatment process, due to the water quality usually could not meet the discharge standards after conventional biological treatment A/A/O process. The results showed that A/A/O+MBR was more effective than A/A/O process for removing ammonia nitrogen (NH3-N) and other refractory compounds. The concentration of NH3-N and CODGr after the treatment by A/A/O+MBR process were 5~10 mg/L and 200 mg/L, respectively. Moreover, it was found that the excessive sludge yielded reduced by 10 % relatived to the system before the transformation, which was a significant reduction in the cost of sludge treatment and disposal. Also, modular-automatic control of MBR membrane modules simplified the operation and maintenance, and eliminated the membrane fouling effectively.关键词
