| abstract | [PROBLEMS] To reduce the amount of sludge adhering to the membrane surface of the separation membrane, reduce the power consumption for sludge removal, and to make the treatment facility compact, efficient and free from the risk of bulking. The purpose is to reduce excess sludge, reduce sludge odor, promote denitrification and dephosphorization, etc. SOLUTION: A low aeration treatment step 2 for biologically treating raw wastewater containing organic matter by low aeration, a membrane separation treatment step 3 for separating sludge from the treated water of the low aeration treatment step 2 by membrane separation, and a membrane separation treatment A sludge digestion treatment step 4 for subjecting the sludge separated in step 3 to a low aeration treatment, and the treated water in the sludge digestion treatment step 4 is returned to the low aeration treatment step 2 as electron acceptor adjustment water. The amount of dissolved oxygen in the low aeration process 3 is 3 mg / L or less, preferably 1 mg / L or less. The separation membrane 5 in the membrane separation treatment step 3 is preferably a hollow fiber membrane module 5. [Selection] Figure 1 |
