    摘要: Developer-containing waste water is subjected to a multi-stage biological treatment. A waste water treatment apparatus for carrying out a two-stage biological treatment has an adjustment tank for receiving raw waste water and for preliminarily adjusting water quality of the waste water. First and second contact aeration tanks are used to biologically treat the waste water. First and second settling tanks are connected to the first and second contact aeration tanks for separating by sedimentation sludge from the waste water. Specifically, the first settling tank is connected to the second contact aeration tank. Sludge separated from the waste water is returned from the first and second settling tanks to first and second mixing tanks, respectively, and mixed with Bacillus Subtilis Kubota (BSK) and excess household sludge. The mixture is aerated and then transferred to the first and second contact aeration tanks, respectively. The aerated mixture in the first mixing tank is also transferred to the adjustment tank in accordance with the water quality of the raw waste water.

    摘要: A water treating apparatus is provided which can treat waste water for use as raw water in an ultrapure water producing system without addition of various kinds of chemicals. The apparatus includes a first water tank for receiving acid waste water, a second water tank for subjecting the waste water from the first water tank to solid-liquid separation and discharging supernatant liquid, an ion exchange tank including ion exchange resin and an aeration tube for generating treated water through a membrane filter, a precipitation tank for settling ion exchange resin, an air lift pump for introducing ion exchange resin from the precipitation tank into the first water tank, and a return air lift pump for returning ion exchange resin from the second water tank to the ion exchange tank. The ion exchange resin acts to exchange ions with fluorine ions of treated water in the ion exchange tank and is regenerated by acid waste water in the first water tank.

    摘要: An operation of a user is inputted to an operating section. A display shows information to the user. A controller causes, in accordance with the operation inputted to the operating section, the display to selectively show: a first screen image showing a plurality of groups, each of which includes at least one digital image stored in a storage medium and categorized in accordance with a predetermined condition, so that the user designates at least one of the groups through the operating section; and a second screen image showing, in a substantial full-screen manner, the at least one digital image included in the at least one of the groups designated by the user, so that the user browses the at least one digital image one by one to specify the number of sheets to be printed with respect to at least one browsed digital image, through the operating section. The controller is operable to cause a printer to execute a printing operation in accordance with the specification performed in the second screen image when a print instruction is inputted to the operating section.
