る。[Effects of Copper and Titanium Oxide on Cleaning Wastewater] In connection with water treatment, copper or titanium oxide is used alone to remove odor components of general bacteria, fungi and algae contained in various wastewaters. There were some reports that were used for the above, and it was thought that the combined use of both would offset each function and function. The present invention finds that copper and titanium oxide are reversely used in combination, and various wastewaters are more effective in removing general bacteria, fungi, algae, other odor components, etc. than by using them alone. It is something. It has long been known that copper has a bactericidal action against microorganisms and the like. The effect of the copper material used in the present invention is improved at a purity of 99.90% or more, but it is found that the purity is further increased, and at a purity of 99.9999% or more, ionization into an aqueous solution is increased. The active oxygen in the aqueous solution is activated by using the above titanium oxide in combination, and general bacteria, fungi, algae, BO
The present inventors have found an effect of improving the disinfection and removal effect on D, COD, etc. by about 100 times, and the present invention utilizes the effect. In addition, by irradiating various types of wastewater using copper and titanium oxide in combination, the catalytic effect of light is promoted, active oxygen is remarkably activated, and the effect is also expanded to sterilize pathogenic bacteria such as Escherichia coli and deodorize ammonia. It is known. It has been found that when copper and titanium oxide are used together, the effect is synergistic when both are placed at a distance from each other, but the detailed action mechanism is unknown.

る事が判る。[Experimental Examples] Experimental Conditions and Samples Washing and discharging water discharged from a kitchen in a service area that is operated daily is collected at the outlet of an oil / water separation tank, and discharged to a 30-liter plastic tank for each test section. A device was prepared to contain 20 L each and output 10 L per minute, and the level of 20 L was maintained by adding effluent water as needed until the test was completed.
Each test section has a width of 30 mm, a thickness of 0, 1 mm, and a purity of 99.
99% copper chips and 90.5% pure titanium oxide were baked on aluminum and 10mm wide, 0mm and 1mm thick chips were installed at intervals of 1cm in 20L discharge water with the addition amount shown in the table of experimental results. After 3 hours, each effluent was sampled and analyzed in accordance with the discharge standards. Experimental result From the table, the washing wastewater treated with the combined use of copper and titanium oxide is also surely reduced in microorganisms, odor components and some other wastewater standard items, and excellent sterilization with the combined use of copper and titanium oxide,
It is clear that a gradual removal effect can be obtained, which means that it is practically effective.
