摘要： PURPOSE:To prevent the agitation of a liquid mixture in a digestion vessel due to the ascension of generated gas and to prevent the deterioration of a treated liquid due to the breakage of flocs and a decrease in the digestion efficiency due to the mixing of bacteria by collecting the generated gas in the liquid, and liberating the gas in the vicinity of the liquid surface. CONSTITUTION:Untreated liquid supply means 2 and 3, a digestion vessel 1 having a treated liquid takeout means 4 and a gas takeout means 5, gas collecting means 14a and 14b arranged in a liquid and used for collecting generated gas in the digestion vessel 1, and vent pipes 15a and 15b whose leading end is opened in the vicinity of the liquid surface to liberate the collected gas are provided. Since the generated gas is collected and liberated in the vicinity of the liquid surface in this way, the agitation of the liquid mixture due to the ascension of the generated gas is prevented, and the deterioration of the treated liquid due to the breakage of flocs and a decrease in the digestion efficiency due to the mixing of bacteria can also be prevented. Accordingly, the anaerobic digestion can be efficiently carried out.

摘要： PROBLEM TO BE SOLVED: To provide a pressure flotation apparatus exhibiting extremely excellent flotation separation efficiency of suspended matter. SOLUTION: Mixed water of raw water with pressurized water is introduced into a center cage 12 through a supply pipe 14 and discharged from an opening 16 of a distributor 15 to the downstream side in the rotative direction. Since a guide plate 17 is projected into the downstream direction of the distributor 15, the mixed water discharged from the opening 16 is restrained from flowing toward a peripheral wall 1a and made to flow quietly to the peripheral direction while hardly forming a turbulent flow. Air bubbles generated from the pressurized water are stuck to suspended matter and the air bubble-stuck suspended matter rises to the surface and becomes floating scum. The floating scum is scraped to the vicinity of the peripheral wall 1a by scraping plates 21, 22, dropped in a scum box 6 by a skimmer 24 and discharged from a discharge port 7.

摘要翻译：要解决的问题：提供一种具有非常优异的悬浮物浮选分离效率的压力浮选装置。解决方案：原水与加压水的混合水通过供应管14被引入中心笼12，并从分配器15的开口16向旋转方向的下游侧排出。由于引导板17向分配器15的下游方向突出，所以从开口部16排出的混合水被抑制流向周壁1a，并且使其静止地流向周向，同时几乎不形成湍流。从加压水产生的气泡被粘附到悬浮物上，气泡粘附的悬浮物质上升到表面并变成浮渣。通过刮板24,22刮掉浮渣，并通过刮板24落下于浮渣槽6中并从排出口7排出，从而将周围壁1a刮到周围壁1a附近。（C）2007，JPO＆INPIT

摘要： PURPOSE:To operate the titled apparatus so as to conserve energy while reducing an installation area, by mounting a partition plate and a flow distribution plate which is inclined downwardly to a direction crossing said partition plate and extends to a liquid mixing part from the lower part of a solid-liquid separation part so as to hold the interval from the lower end of said partition plate. CONSTITUTION:When a raw solution such as waste water is supplied from a raw solution pipe 13 and air is supplied from an air supply pipe 15 to perform air diffusion from an air diffusion apparatus 2, said raw solution is mixed with the activated sludge in an aeration part 12 and aerated. The liquid mixture of the aeration part 12 rises from a liquid mixture part 4 through a rising part 7 and the decomposition of an org. substance is performed during rising by oxygen in air. The liquid mixture separated from air in the upper part of the liquid mixture part 4 is fallen through a falling part 8 and a part thereof rises through the solid-liquid separation part 5 and the greater part thereof is recirculated to the liquid mixture part 4 from the lower part of the solid-liquid separation part along a flow distribution plate 10 and receives aeration. Excessive sludge is conc. in a waste sludge pit 16 provided to the bottom part of the aeration tank 1 and discharged from a sludge discharge pipe 17.

摘要： PURPOSE:To obtain economically the water having a specified quality by supplying an adsorbent into an adsorption apparatus and discharging the water in association with the quality of the original water. CONSTITUTION:The flow rate and quality of the original water 11 to be supplied into a treating tower 1, such as an ultraviolet absorption rate (UV) and COD, are measured, and the value is inputted to a controller 16 such as a computer. And the amt. of an adsorbent necessary for making the present original water into the treated water having a specified quality is calculated in the controller from the specified quality of the treated water such as COD value, and the time of the exchange or removal of the adsorbent is also calculated. The calculated result is sent into a control 16b of the controller 16 which controls the supply of the new adsrobent at constant time intervals and the discharge of the adsorbent in the treating tower by an amt. almost identical with the supply.
