Abstract: An accelerated oxidation treatment method of performing oxidation treatment upon treatment water by supplying ozone and hydrogen peroxide to the treatment water, including an accelerated oxidation treatment process of bringing hydrogen peroxide and ozone into contact with the treatment water, and a bromate ion concentration measurement process of measuring the bromate ion concentration in the treatment water after the accelerated oxidation treatment process, with the amount of hydrogen peroxide supplied in the accelerated oxidation treatment process being adjusted on the basis of the measured value of bromate ion concentration.

Abstract: The process includes operation as follows: putting ozone generated by an ozone generator into raw water, in a normal mode, to subject the raw water to ozone treatment; injecting a flocculant into the raw water before or after the ozone treatment; filtering the raw water by a separation membrane after the ozone treatment and the injection of the flocculant; and intermittently setting cleaning mode to put a larger quantity of cleaning ozone than that in the normal mode into the raw water so as to intermittently increase the concentration of dissolved ozone, thereby cleaning the filtration membrane.

Abstract: This invention relates to a garment with a crotch part used in contact with skin, including: a garment main body including a stretchable crotch cloth piece; and a second crotch cloth piece on which an absorbent article is to be applied and held, provided on the inner side of the crotch cloth piece of the garment main body, wherein the second crotch cloth piece is mounted to the garment main body at its front and rear edges and is mounted to the crotch cloth piece of the garment main body at least in one portion of its center line, and right and left edges of the second crotch cloth piece are not bonded to the garment main body and are in free state. An absorbent article can be held at a determined position on the crotch part of the garment with stability and security. The garment also is excellent in close contact to the pudendal cleft region, is difficult to be steamed in use, and has fine appearance and good wearing comfort after mounting an absorbent article.
