Abstract: Disclosed is a sequencing batch reactor (SBR) for sewage treatment. The SBR is applicable to an energy-producing sewage treatment system. The SBR includes a treatment tank and a hybrid bacterial strain screening tank. The treatment tank removes ammonium contained in supernatant liquid using anaerobic ammonium-oxidizing (anammox) bacteria. The hybrid bacterial strain screening tank screen anammox bacteria granules out by passing the supernatant liquid discharged from the treatment tank through the hybrid bacterial strain screening tank. The SBR generates biogas using the anammox bacteria and reduces the nitrogen content in the supernatant liquid. The SBR can separate the anammox bacteria granules with high separation efficiency, thereby shortening sewage treatment time and recycling activated sludge, resulting in a dramatic decrease in the amount of waste sludge.

Abstract: A method and program for generating a responsive image is provided. The method includes obtaining, by a computer, a first image, receiving, by the computer, an input for specifying a specific playback range, and specifying playback range, the playback range corresponding to an entire interval or a partial interval in the first image, connecting, by the computer, a specific input operation to an entire region or a specific region of one or more image frames included in the playback range. The input operation adjusts movement of the image frames in the playback range and corresponds to motion of an object of the playback range in the first image. The computer connects an image captured by a typical image capture device to a specific input operation such that a user feels as if the image detects and responds to his or her input operation upon playback.
