Abstract

The work conducted a pilot-scale study of sewage treatment of a certain river in the Yuquan District of Huhhot by aerobic-anaerobic fixed-bed bioreactor constructed by Kaldnes carriers. After the reactor started off to work, the biological film on the stuffing increased the thickness to about 1 mm a week later. It is shown from the results after a continuous operation of 30 d that the ammonia nitrogen will become 5-10 mg/L when the water ingress COD is 60-150 mg/L and will get lower than 2 mg/L when the effluent COD is under 40 mg/L. If the concentration of effluent suspended solid without precipitation is below 10 mg/L and the chroma is inferior to 1,00 after the device is of stable operation, it can be indicated that the reactor is effective for the removal of organic matter, ammonia nitrogen and chroma. The pilot-scale experiment in the work verifies the feasibility and advantages of river sewage treatment in use of this reactor, which proposes the new concepts and methods for the river sewage treatment.
