<p>The present invention relates to a reusing device and method of wastewater treatment by combining sequencing batch and membrane separation. The present invention introduces a batch reactor process in a separation membrane process, and minimizes microorganism concentration (mixed liquor suspended solids; MLSS) of mixed microorganism which flows in a membrane filtration process. The batch reactor operates a biological nitrogen-phosphorous removal process in aerobic condition and anaerobic step, maximizes treatment of organic matters and nutrient salts, and minimizes separation membrane unit pollution which can be on the rise in a MBR process, thereby extending life of a separation membrane unit and extending the replacement period.</p> |
