PHOTOOXIDATION WATER TREATMENT DEVICE

摘要

A photooxidation water treatment device 10 includes a ultraviolet ray-ozone reaction chamber 40. To an inlet 44a of the reaction camber 40 is connected a pump 12 for supplying water to be treated via a T pipe 20 to which an oxidizing agent tank 30 is connected. An outlet 46a is connected to an upper inlet 44b via a circulating pump 50 and an ejector 52. A protection tube 60 is provided axially in the central portion of the reaction chamber 40. A mercury lamp 62 is provided in the protection tube 60 which is connected to a filter 72 and the ejector 52. The inlets 44a and 44b and outlets 46a and 46b are formed horizontally obliquely to a line normal to the circumference of the reaction chamber 40 so as to cause a spiral flow of water to be treated about the protection tube 60.
