摘要： Waste water containing organic materials is introduced into an aeration tank, and is subjected to aeration treatment in the presence of activated sludge, while supplying oxygen to the aeration tank. The tank provided with an air diffusion pipe at the bottom of the tank, an air dispersion device above the air diffusion pipe and a plurality of inside cylinders above the air dispersion device. An overall circulating stream and partial circulating streams are generated in the aeration tank.

摘要： Method of and apparatus for separation of solids from a liquid employs an elastic sheet filter which has pores of diameter larger than an average diameter of the solid and smaller than the maximum diameter thereof. The liquid is filtered under pressure by a filtered residue layer developed on the sheet filter. Then liquid is rapidly introduced to the sheet filter portion from the reverse direction to liquid flow occured during the filtration of the liquid so that the sheet filter and filtered residue layer pressed during the filtration is rapidly pressed in the reverse direction, whereby the filtered residue layer is flaked out in the liquid and separated therefrom.

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。
