Wastewater treatment apparatus including upflow anaerobic reactor and wastewater treatment method using the same

摘要

The present invention is the introduction portion installed in the outer lower anaerobic reactor; An inlet device including a hole formed in a lower portion of the anaerobic reactor in direct connection with the electric inlet; Mixing devices installed at uniform intervals on the mixing device main shaft in the anaerobic reactor; An outlet device having a radial structure at the center of the installation of the weir, which is located above the anaerobic reactor so that the reaction water containing some sludge may flow out into the aerobic reactor in the reaction by the electric mixer; And a sludge aggregator located below the anaerobic reactor for collecting sludge precipitated by gravity from the reaction by the electric mixer to the center of the anaerobic reactor, and the apparatus comprising an upflow anaerobic reactor. It relates to a wastewater treatment method used. By using the wastewater treatment apparatus including the upflow anaerobic reactor of the present invention, not only biodegradable and toxic substances, or organic wastewater containing nutrients such as nitrogen and phosphorus and heavy metals can be biologically treated, The sludge can be kept smaller in volume than other biological reactors, making it possible to treat wastewater economically. In particular, the upflow anaerobic reaction tank of the present invention can omit the concentration tank in the case of sewage treatment plant due to the high concentration of sludge, and can use the primary sedimentation tank as a reaction tank, as well as save the construction cost and operating cost of the treatment plant. It can get a side effect.
