METHOD AND APPARATUS FOR AEROBIC TREATMENT OF ORGANIC WASTE SOLUTION

摘要

PURPOSE:To provide a method and apparatus for the aerobic treatment of an org. waste soln. capable of subjecting a reaction soln. to membrane separation in a high flux while preventing the clogging of a separation membrane to obtain treated water of high quality to enable the reutilization of water and capable of reducing the vol. of excessive sludge without lowering load and treatment efficiency. CONSTITUTION:An org. waste soln. 13 is introduced into an aerobic treatment tank 1 to be subjected to aerobic treatment and this reaction soln. is subjected to membrane separation in a membrane separator 12 to be separated into a filtrate 12b and a conc. soln. 12c and the reaction soln. or the conc. soln. is introduced into an ozone treatment tank to subject activated sludge to ozone treatment and the ozone treated sludge is introduced into the aerobic treatment tank 11.
