摘要： The present invention relates to an apparatus for removing suspended matter, organic matter and nitrogen compounds in the sewage. A processing tank is provided with a floating-separation zone at the upper portion thereof and an electrolysis zone below the floating-separation zone. A bed of porous adsorbent is disposed in the electrolysis zone and electrodes are disposed among the adsorbent. Bubbles generated upon the feed of current to the electrodes rise up through the floating-separation zone to remove the suspended matter and the organic matter in the sewage before introducing the sewage into the electrolysis zone. The porous adsorbent is polarized by the feed of current to the electrodes and results in removing matter remaining in the sewages, especially nitrogen compounds.

摘要： A filtration method employs a water tank, a filtration tank within the water tank and provided with a filter material for straining solids from sewage supplied to the water tank, to produce filtered water within the filtration tank, a shield or guide plate encompassing the filtration tank adjacent the filter material to provide a liquid flow passage therebetween, and a bubble generator having a plurality of openings for generating bubbles within the flow zone, so that the bubbles pass along the filter material. Sewage water that is supplied to the water tank is conducted to the flow zone where part of the water passes through the filter material and solids suspended therein are strained out and attached to the outer surface of the filter material. The generated bubbles passing through the flow zone create a difference in pressure between a point at which the fluid including the bubble is flowing in the water flow zone and an opposite point within the filtered water chamber of the filtration tank, which will dislodge the solids attached to the filter material and prevent clogging of the filter material so that the filtration and passage of bubbles may be continuous without clogging.
摘要翻译：过滤方法在水箱内采用水箱，过滤箱，并提供过滤材料，用于将固体从施加到水箱的污水中固化，在过滤罐内产生过滤水，围绕过滤罐的屏蔽或引导板邻近过滤材料以在其间提供液体流动通道，以及具有多个用于在流动区域内产生气泡的开口的气泡发生器，使得气泡沿着过滤材料通过。供给到水箱的污水进入到水分通过过滤材料的流动区域，悬浮在其中的固体被过滤并附着在过滤材料的外表面上。产生的气泡通过流动区域产生在包含气泡的流体在水流区域内流过的点与过滤罐的过滤水室内的相反点之间的压力差，这将移除附着的固体并且防止过滤材料的堵塞，使得气泡的过滤和通过可以连续而不堵塞。

摘要： A multi-stage distillation plant consisting essentially of a multi-flash evaporator provided with a multi-flash chamber which is divided into a heat recovery section and a heat rejection section. In this multi-stage flash distillation plant, the aforesaid flash evaporator is provided with a deaerator for deaerating cold sea water, a thickener for separating brine containing a relatively great amount of seeds, from concentrated brine which has been extracted from a front chamber of the final stage flash chamber, and a seed mixing tank for obtaining a seed-mixed brine, whereby part of the sea water which has passed through the deaerator is supplied as a feed sea water to the rear chamber of the final stage flash chamber, while the brine containing a relatively great amount of seed and extracted from the thickener is joined to the seed-mixed brine fed from the seed mixing tank. Thus, the confluent brine thus joined together is discharged for deaeration into the final stage flash chamber from a distributor provided in the rear chamber thereof. According to another aspect of the invention, the aforesaid deaerator is omitted and the feed sea water which has not been subjected to deaeration is joined to the aforesaid confluent brine and is discharged for deaeration from the distributor.
摘要翻译：一种多级蒸馏设备，主要由多闪蒸发器组成，多蒸发蒸发器设置有多闪蒸室，其分为热回收段和排热段。在这种多级闪蒸装置中，上述闪蒸器具有用于对冷海水进行脱气的除气器，用于从含有相对大量种子的盐水中分离的浓缩物，该浓缩盐水从已从最后阶段闪蒸室和用于获得种子混合盐水的种子混合罐，由此将通过除气器的一部分海水作为进料海水供应到最终级闪蒸室的后室，而含有相对大量种子并从增稠剂中提取的盐水与从种子混合罐供给的种子混合盐水相连。因此，这样连接在一起的汇合盐水从设置在其后室中的分配器排出进入最后阶段闪蒸室。根据本发明的另一方面，省略了上述脱气器，并且没有进行脱气的进料海水与上述汇合盐水接合，并从分配器排出以脱气。

摘要： The present invention relates to a method for removing suspended matter, organic matter, foaming matter and nitrogen compounds in sewage and to an apparatus for the method.The suspended matter and the organic matter are removed by means of first fine bubbles and the foaming matter is removed by means of second bubbles having a larger bubble average diameter. The sewage treated by the first and second bubbles passes through a bed of porous adsorbent polarized by the feed of current, so that nitrogen compounds and the organic matter remained in the sewage are adsorbed and removed. It is also provided with a step for removing the suspended matter and the organic matter remained in the sewage by means of third fine bubbles before transferring the sewage to the bed of adsorbent.
