摘要： Disclosed herein is a dynamic aperture driving apparatus for adjusting the amount of light of a projection optical system and a method of controlling the same. The system includes a rotation means, a driving means, a first detection means and a first detection means. The rotation means is connected at the upper end thereof to the dynamic aperture to be rotated to the right and left within a range of rotating angles. The driving means rotates the rotation means to the right and left according to a predetermined electric signal. The first detection means detects the position of the rotation means using a Hall effect. The second detection means detects the operational error of the first detection means due to variation in temperature.

摘要： The present invention provides to a method for removing nitrogen and phosphorous in wastewater simultaneously from wastewater by employing fermentation broth obtained by anaerobic fermentation of organic solid wastes. The method for removing nitrogen and phosphorous in wastewater of the invention comprises the steps of subjecting organic waste material to anaerobic fermentation at 30 to 40° C. for 2 to 4 days by using anaerobic sludge to obtain fermentation broth; and, adding the fermentation broth to a sequencing batch reactor with alternating anaerobic-aerobic-anoxic cycles under anaerobic and anoxic conditions in a separate manner. In accordance with the present invention, nitrogen in the influent wastewater can be removed more than 95% in total and phosphorous concentration can be kept below 1 ppm regardless of the concentration of organic materials in the influent wastewater. Further, the present method requires no extra pretreatment steps or chemicals which are essential to remove residual ammonia nitrogen in the prior art systems, and lowers the overall cost for wastewater treatment due to the usage of organic waste materials.
摘要翻译：本发明提供一种通过使用通过有机固体废物的厌氧发酵获得的发酵液，从废水中同时除去废水中的氮和磷的方法。本发明废水中除氮和磷的方法包括以下步骤：通过使用厌氧污泥将有机废物在30〜40℃进行厌氧发酵2〜4天，得到发酵液; 并将发酵液添加到在厌氧和缺氧条件下以分开的方式交替的厌氧 - 需氧 - 缺氧循环的测序间歇反应器。根据本发明，流入废水中的氮总量可以去除95％以上，磷浓度可以保持在1ppm以下，而与进水废水中有机物质的浓度无关。此外，本方法不需要额外的预处理步骤或在现有技术系统中除去残余氨氮所必需的化学品，并且由于使用有机废物材料而降低了废水处理的总体成本。
