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： PURPOSE:To carry out efficient anaerobic digestion with a small setting area by providing two partition plates at the upper part of a digestion vessel to separate the vessel into a liquid mixture part consisting of an ascending part and a descending part, and providing a rectifying plate extending from the lower part of the solid-liquid separation part to the liquid mixture part. CONSTITUTION:A digestion vessel 1 having an untreated liquid inflow part 2 at the bottom, a partition plate 3 extending from above the liquid surface of the vessel 1 into the liquid and separating the upper part of the vessel 1 into a solid-liquid separation part 5 and a hermetic liquid mixture part 4, a treated liquid pipe 14 communicating with the upper part of the solid- liquid separation part, and a gas discharge pipe 15 communicating with the upper part of the liquid mixture part are provided. And a partition plate 6 whose upper end is situated under the liquid surface of the liquid mixture part, whose lower part is inclined downward while keeping an interval from the leading end of the partition plate 3 and extends to the lower part of the solid-liquid separation part, and which separates the liquid mixture part into an ascending part 7 and a descending part 8, and a rectifying plate 10 are provided. Namely, the flow of generated gas into the solid-liquid separation part is prevented, and the sludge settled at the solid-liquid separation part is returned to the digestion part by utilizing a spiral flow of the generated gas. Accordingly, the anaerobic digestion is efficiently carried out with a small setting area.

摘要： PURPOSE: To provide an electromagnetic filter of small power consumption and low running cost, by connecting a controlling means, used for changing the magnetic force of a magnetic material which is magnetized by an exciting coil, to the exciting coil.
CONSTITUTION: A perforated plates 2 made of magnetic materials are arranged at the upper and lower sides in the inside of a filtering tower 1 made of stainless steel plate, and steel balls and steel wire-nets made of magnetic materials are packed between the plates 2 to constitute a magnetic filter-layer 3. A return frame 4 is provided to the outside of the tower 1 by surrounding the layer 3, and an exciting coil 5 is arranged in the inside of the frame 4. A controlling means 7 is provided to the place between an electric power source 6 and the coil 5 to gradually enhance the intensity of an impressed magnetic field and stengthen a magnetic force by the controlling means 7 during running, that is, through the period of initial, intermediate, and final stages of water passing. The controlling means 7 is used for changing an electric current value to be supplied to the exciting coil stepwise or in a stepless state, or changing the number of turns of the exciting coil substantially.

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 prevent a pressurized gas from contacting a filtration device by cleaning the filtration device reversely by supplying a pressurized gas to a cushion tank intervening in a permeated liquid delivery line and stopping the cleaning when the amount of the permeated liquid becomes less than a predetermined amount. CONSTITUTION:A cushion tank 10 having a capacity to be able to store a permeated liquid in a predetermined amount as well as pressurized gas supplying means 12 to pressurize the permeated and stored liquid and a detector 11 to detect the amount of a permeated liquid discharged by the pressurized gas is installed in a permeated liquid delivery line 7. Further, at the time of reverse cleaning, a pressurized gas is supplied to the tank 10 and the permeated liquid in the tank 10 is made to flow to a raw liquid side 2 by a reverse cleaning controlling means 15 so that pressurized gas supply may be controlled to stop when the amount of the permeated liquid in the tank 10 becomes less than the predetermined amount. As a result, the pressurized gas is prevented effectively from contacting the filtration device 1 and the back-washing is carried out safely.
