<p>The present invention relates to an advanced sewage treatment apparatus. The advanced sewage treatment apparatus can conduct anaerobic and anoxic treatment processes in a biological treatment tank at the same time and reduce the amount of the floating sludge while maintaining a feed rate of the sewage. According to the present invention, the advanced sewage treatment apparatus includes a biological treatment tank which purifies the sewage through aeration, sedimentation, and extraction processes, and discharges the purified water to the outside after the sewage is supplied. The advanced sewage treatment apparatus also includes: a steel mesh structure fixed to the biological treatment tank at a predetermined height; and cylindrical contact members which are stacked and irregularly arranged in the steel mesh structure and have the opened upper and lower parts to let the sewage pass through.</p> |
