Abstract: The problem addressed by the present invention is to provide a method of treating an organic substance-containing waste liquid, and a treatment apparatus therefor, and an additive for treating an organic substance-containing waste liquid, and a bacterium for degrading an organic substance component or the like in the waste liquid, capable of accomplishing at least one of treatment of the organic substance-containing waste liquid with a high efficiency and a high treatment rate, without substantially generating a foul odor, and obtainment of water quality that is suitable for releasing to sewage, a public water area, or the like. This problem is solved by providing a method of treating an organic substance-containing waste liquid characterized by contacting an activated sludge containing a specified bacterium with an organic substance-containing waste liquid.

Abstract: A catcher frame apparatus is provided including a catcher frame and a catcher roller mounted to the front lower end of a catcher supporting unit of the catcher frame along the direction of the width of a machine body. The catcher frame is connected to the machine body so as to be capable of rotating about an axis of rotation extending along the direction of the width of the machine body, and the catcher supporting unit of the catcher frame is arranged in front of a lawn mowing unit, so that substantially the entire weight of lawn chips stored in a grass catcher supported by the catcher supporting unit is applied to the catcher roller.
