Continuous Batch Biofilm Reaction Wastewater Treatment System with Semi-Floating Carrier Receptor

摘要

The present invention relates to a wastewater treatment apparatus in which a semi-floating carrier receptor is installed in a continuous batch reactor, and has a slow growth rate by installing a semi-floating carrier receptor filled with a microbial fixation carrier which is moved up and down according to the flow rate of the reactor. The purpose of the present invention is to maintain a constant microorganisms, such as nitrifying bacteria, which are easily leaked to the outside, and to improve the treatment efficiency of high concentration wastewater with high nitrogen and phosphorus content and high load fluctuations. To this end, the present invention floats on the surface of the waste water introduced into the reaction vessel by buoyancy buoyancy buoy to move up and down by the flow rate of the waste water; A polyhedral semi-floating receptor formed in the upper part of the floating buoy, the upper part of which has a plurality of lattice-shaped spaces floating on the surface of the wastewater in the reactor while the lower part is submerged by the self-load and the buoyancy of the floating buoy; Filled in the space of the semi-floating receptor by installing a floating buoy and a semi-floating receptor which are installed at a place in the reactor and moved up and down by the change of the flow rate of the wastewater introduced into the reactor. It is characterized by including the microorganism fixed carrier. By this configuration, the present invention prevents the loss of nitrifying bacteria attached to the microbial fixation carrier, as well as the nitrification of the microorganisms attached to the microbial fixation carrier in contact with the air regardless of the operating conditions. It is effective in improving the removal efficiency of the high concentration of nitrogen and phosphorus contained in the waste water by causing denitrification continuously.
