摘要： PROBLEM TO BE SOLVED: To remove a foreign matter by removably fitting an adapter to a vacuum valve when a controller is removed from the vacuum valve, connecting the vacuum valve and one end of an intake pipe via a three-way valve, and connecting a vacuum generating member to the other end of the intake pipe. SOLUTION: When such an abnormality occurs that a foreign matter 30 is pinched between the valve element 3a and valve seat 3b of a vacuum valve 3, a vacuum valve controller 4 is removed from the vacuum valve 3, and an adapter 11 having a connection pipe 12 branched from a three-way valve 13 is fitted. The tip of the connection pipe 12 and the tip of an intake pipe 7 are connected to the three-way valve 13, a vacuum generating member 14 is fitted to the other end of the intake pipe 7, and the vacuum valve 3 is opened. After the foreign matter 30 is moved and sucked into a vacuum main pipe via a vacuum branch pipe and the vacuum valve 3 is returned to the normal state, the adapter 11 is removed, and the vacuum valve controller 4 is fitted. The foreign matter 30 of the vacuum valve 3 is quickly removed, and the maintenance efficiency can be improved.

摘要： PURPOSE:To reduce the burden of exposure to air in a sewage treatment works by exposing a vacuum tank to oxygen including gas after the tank is set under atmospheric pressure at night, to drain soil water in the tank, and by making the tank and vacuum pipings communicate with each other, to suck the soil water in a soil water measure, to the tank. CONSTITUTION:For about 16 hours during a daytime and night, a vacuum pump 6 is operated, and soil water drained from a soil water source 1 is sucked into a vacuum tank 5. When the discharge quantity of the soil water is remarkably lowered at midnight, then the vacuum tank 5 and vacuum pipings 4 are interrupted from each other and after that, into the tank 5, atmospheric air is introduced, and it is roughly set under atmospheric pressure. The air is fed to an air dispersing pipe 7 in the tank 5 from a blower 8, and the soil water is exposed to air for about 8 hours. Then, a pressure-feeding pump 9 is operated, and the soil water in the tank 5 is drained. Besides, the tank 5 and the pipings communicate with each other, and the pump 6 is operated, and the interior of the tank 5 is set under negative pressure again.

摘要： PROBLEM TO BE SOLVED: To detect ant abnormal state before the overflow of waste water by connecting an outlet pipe in the middle of a connection pipe jointing a controller to a vacuum piping, installing a movable member to an open end of outlet pipe and connecting a float member to a movable member. SOLUTION: When a vacuum valve 3 is operating normally, a connection pipe 5, a branch vacuum pipe 22 and an outlet pipe 13 are maintained to a vacuum state. And the water level in a catch basin 1 is at the NL position, a float 32 is at the NL position, and a movable piece contacts to the end face of outlet pipe ands closes it. And if the water level in a catch basin 1 rises to the position of HL, the float 32 also rises to the position of HL, the movable piece is separated from the end face of the outlet pipe 13 by the link mechanism containing first and second rods 19a, 19b, and atmospheric air flows to the vacuum valve and the vacuum is destroyed. Moreover, are is sucked by the warning horn attached to the end portion of the outlet pipe 13 and a warning sound is generated and the anomaly in the catch basin 1 is detected. Thus, the anomaly in the vacuum valve 3 can be detected before the waste water overflows from the catch basin 1.

摘要： PURPOSE:To reduce the burden of exposure to air in a sewage treatment works by arranging bearing bodies with fixed activated sludge, on the internal walls of vacuum pipings, and by permitting soil water and the activated sludge to come in contact with each other during the shifting of the soil water in the vacuum pipings. CONSTITUTION:Soil water drained from a soil water source 1 flows downward to be stored in a soil water measure 2. When the water level of the soil water is heightened to a fixed or more limit, then a vacuum valve 3 is opened, and the soil water is sucked from the opening ends of vacuum pipings 4. The dirty water comes in contact with the activated sludge bearing bodies 10 of diatomaceous earth or the like attached on the internal surfaces of the pipings 4, and the organic substance is decomposed. Besides, the soil water is sucked into the vacuum tank 5, and after that, the soil water is fed to a precipitation tank 8 by a pressure-feeding pump 7.

摘要： PROBLEM TO BE SOLVED: To prevent the increase of lift loss in a vacuum pipe only by addition of a simple structure, by installing a pump between a sewage storage tank connected to the upstream side vacuum pipe and the downstream side vacuum pipe. SOLUTION: When an electric motor-driven valve 8a and a solenoid valve 8c are closed and a motor-driven valve 8b is opened and the water level in a sewage storage tank 4 is lowered to L or a lower level, sewage flows from the upstream side vacuum pipe 1 in the tank 4 and the water level rises up to H. Then, the motor-driven valve 8a is opened and the motor-driven valve 8b is closed and the pump is driven. Then, the water level in the tank 4 is lowered to L or a lower level and the pump 5 is brought to a stop, and the motor-driven valve 8a is closed and the solenoid valve 8c is opened to prevent air-lock and after air has been taken into the downstream side vacuum pipe 2, the solenoid valve 8c is closed and the motor-driven valve 8b is opened to return the condition to the initial state. In this way, since the sewage in the pipe 1 is transferred to the pipe 2 by the pump 5, even if the pipe 2 is positioned at a higher level than the pipe 1, lift loss is not brought.
