<p>A method for treatment of wastewater by means of membrane bioreactor, in which wastewaters are delivered consists in withdrawing excess biological sediments from bioreactor, mixing them with liquid drains, which contain sufficient amount of polyelectrolyte and which are obtained at the stage of sediments drying, which is accompanied by introduction of polyelectrolyte, and dividing biological sediments filled with polyelectrolyte, and returning liquid drains free from polyelectrolyte, and returning formed liquid drains free from polyelectrolyte to the inlet of membrane bioreactor, and formed biological drains filled with polyelectrolyte are directed to the stage of drying.</p> |
