    • 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.
    • 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。

    • The present invention provides a method for manufacturing organic acid by high-efficiency fermentation, which comprises the steps of continuous culture of organic acid bacteria and collection of organic acid produced from the culture employing a cell-recycle multiple-stage continuous fermentor with serially connected fermentors, each of which comprises a fermentor containing a ferment container, temperature controller, stirrer, and pH controller; pumps for efflux-circulation of media from the fermentor; and, cell separator for separation and circulation of media from the pumps. According to the present method, the high-concentration lactic acid of 90 g/L can be produced with the high productivity of 50 g/L/h, which can reduce the facility cost and production cost in the bulk manufacturing process. In addition, the present invention can be effectively applied to the production of other organic acids such as acetic acid, formic acid, citric acid, malic acid, maleic acid, fumaric acid, and succinic acid, which show the end-product inhibition.
    • 本发明提供了一种通过高效发酵制造有机酸的方法,其包括以下步骤:连续培养有机酸细菌和收集由使用连续发酵罐的细胞循环多级连续发酵罐的培养物产生的有机酸 ,其中每个包含含有发酵容器,温度控制器,搅拌器和pH控制器的发酵罐; 用于来自发酵罐的介质的外排循环的泵; 以及用于从泵分离和循环介质的细胞分离器。 根据本方法,可以以50g / L / h的高生产率生产90g / L的高浓度乳酸,这可以降低批量制造过程中的设备成本和生产成本。 此外,本发明可以有效地应用于生产其它有机酸如乙酸,甲酸,柠檬酸,苹果酸,马来酸,富马酸和琥珀酸,这些有机酸显示出最终产物的抑制作用。

    • A switch assembly which has a mount (12), an elongate member (14), a switch (16) and a fulcrum (18). Pressing on elongate member (14) provides a force to actuate switch (16). Elongate member (14) is resilient or, alternatively, is resiliently biased to return to an unactuated position. Fulcrum (18) is movable along a length of elongate member (14). Positions of fulcrum (18) along the length enables variation of the force to actuate switch (16). As a result of this variation, different tactile feel of the switch assembly can be provided depending on position of fulcrum (18) relative to switch (16). Fulcrum (18) can also be positioned along elongate member (14) to provide a locking position that prevents switch (16) from being actuated.
    • 具有安装件(12),细长构件(14),开关(16)和支点(18)的开关组件。 按压细长构件(14)提供力以致动开关(16)。 伸长构件(14)是弹性的,或者可选地,弹性地偏置以返回到未致动位置。 支点(18)可沿细长构件(14)的长度移动。 沿长度的支点(18)的位置使得力的变化能够致动开关(16)。 作为这种变化的结果,可以根据支点(18)相对于开关(16)的位置来提供开关组件的不同触觉。 支点(18)还可以沿着细长构件(14)定位,以提供防止开关(16)被致动的锁定位置。
