Sewage and waster water treatment using the electro coagulation and electro precipitation

摘要

A wastewater treatment apparatus using electrocoagulation and precipitation is provided to purify waste water cleanly with simple structure of the apparatus and to extend lifetime of electrodes. A wastewater treatment apparatus using electrocoagulation and precipitation includes a coagulation vessel(1) and a precipitation vessel(2). A plurality of plate-shaped electrodes(11) are installed in the coagulation vessel vertically. A plurality of reticular electrodes(21) are arranged inside the extraction reaction tub vertically. An inlet hole(1a) is formed on a part which is adjacent to the floor of the coagulation vessel. An outlet hole(1b) is formed on an upper part of the coagulation vessel. The inlet hole is formed in the in-between of the precipitation vessel. The outlet hole is formed on the top of the precipitation vessel. An iron oxide outlet(1c) is formed on the bottom of the coagulation vessel.
