    Abstract: PURPOSE: Disclosed is an apparatus for treating wastewater electrochemically, in particular for treating high concentration wastewater by using electrolytic oxidation reaction adopting insoluble catalytic electrodes and a conductive floating catalyst, thereby free of additional chemicals or processes. CONSTITUTION: A reactor mainly consists of a power supplying means (1), an aerator (6), a plurality of air injection holes (10), a plurality of cathodes (4), a plurality of anodes (2). Wastewater which is stored in a storage basin (5) flows into the reactor (9) through an inlet port (8), and discharged through an outlet port (7) after contacting with anodes, cathodes, and conductive floating catalyst (3). The anode made by immobilizing Ru-Ir-Sn oxides on the surface of titanium plate decomposes organics and color-causing materials, dissolved heavy metals in wastewater are electrodeposited on the surface of cathode made of iron or nickel plate. Also, the floating titanium/iron catalyst coated with iron oxides accelerates organics decomposition through chemical reaction with hydrogen peroxide generated in the surface of anodes. In the reactor, anodes and cathodes are installed to be different height each other for maximizing contacting area between wastewater and each electrode, and aeration is accompanied to both separate bubbles generated in the each electrode and maintain wastewater flow stable.

    Abstract: PURPOSE: A system for simultaneously removing organics, solids, nitrogen and phosphorus by alternated aeration is provided, which is characterized in that only two submerged filtering reactors are additionally installed to conventional biological process. Two submerged filtering reactors are operated with alternated aeration, so anoxic and aerobic conditions are built alternately. CONSTITUTION: The system is composed of the following parts continuously: an anaerobic tank(1), two submerged filtering reactors(2)(3), a contact oxidation tank(4), and a sedimentation tank(5). For increasing treatment efficiency, media is packed into two submerged filtering reactors(2)(3). Quantity of packed media is 3/5 of depth of reactor for synergistic effect of attached microorganism and suspended microorganism.

    Abstract: PURPOSE: Disclosed is a wastewater treatment system with a pair of biofilm reactors being interconnected each other, in which one biofilm reactor is operated in an aerobic condition, the other biofilm reactor is operated in an anaerobic condition. Wastewater flows into the upper mouth of an anaerobic reactor, travels through the anaerobic reactor into the upper mouth of an aerobic reactor via a pair of interconnecting pipes (6A, 6B). In addition, back-washing is conducted periodically to prevent clogging of packed media and back-wash water travels through a storage tank (13) into a flow equalization tank (2). CONSTITUTION: This wastewater treatment system consists of a pair of biofilm reactors being interconnected each other in which two diffusers (11A, 11B) are installed at each reactor respectively, and pipes (10A, 10B) for back washing are installed at the bottom of each reactor; interconnecting pipes (6A, 6B) cross-interconnecting two biofilm reactors.

    Abstract: 본발명은연계교차된 2 상하향류생물막반응기시스템및 이를이용하여폐수내에존재하는유기물, 고형물, 질소및 인을동시에제거하는폐수처리방법에관한것이다. 본발명의폐수처리방법은 2대의하향류생물막반응기 (제1 및제2 반응기)에서폭기공정의작동과정지를번갈아수행함으로써, 각반응기의운전조건을반응기의체류시간에따라한 사이클에서는각각혐기성과호기성으로, 다음사이클에서는각각호기성과혐기성조건으로변화시키면서서로연계처리한다. 이때, 한반응기내에서운전조건이호기성→ 혐기성→ 호기성→ 혐기성으로계속적으로변화시키면서폐수를처리하므로, 호기성조건에서유기물산화, 고형물여과, 질산화및 인섭취반응이일어나고, 혐기성조건에서유기물분해, 고형물여과, 탈질화및 인방출반응이일어나, 폐수내에존재하는유기물, 고형물, 질소및 인이모두제거되고, 운전후에는생물막충전층의역세척공정을수행하므로, 생물막충전층의막힘현상을예방할수 있다.
