Abstract:
A wastewater treatment conduit through which wastewater containing organic contaminant materials is passed to have the organic contaminant materials oxidatively decomposed therein which comprises:(a) a straightly tubular part having a rectangular or circular cross section; (b) a radical generating part consisting of (b1) a first truncated pyramidal or conical tubular member having a coating layer of a water-insoluble metal oxide coming into contact with the wastewater to serve as a positive electrode and connected at the broader end to the upstream end of the straightly tubular part, the narrower end being open, and (b2) a rod member having a surface of a corrosion-resistant metal to serve as a negative electrode and inserted into the truncated pyramidal or conical tubular member along the axial line thereof, and (c) an ultrasonic part consisting of (c1) a second truncated pyramidal or conical tubular member connected at the broader end to the downstream end of the straightly tubular part, the narrower end being open, and (c2) an ultrasonic vibrator mounted on the second truncated pyramidal or conical tubular member (c1).
