摘要： PURPOSE:To permit stable control of aeration intensity over a wide range by converting the rotating speed of a mechanical stirring and air diffusing device installed in an aerobic tank according to the set value of the concn. of dissolved oxygen. CONSTITUTION:The rotating speed of the underwater mechanical stirring and air diffusing device 2 installed in the aerobic tank 1 such as an aerobic bioreaction tank or control tank is converted automatically and continuously or automatically and intermittently or by an arbitrary manual operation according to the set value of the concn. of the dissolved oxygen. The stable control of the aeration intensity over a wide range is thereby permitted. As a result, the size of air feed plants 3-5 is exceedingly reduced and the control of a blower 3 to be used for air feeding is considerably facilitated. Effective oxygen transfer is executed and the effect of the treatment is improved. The DO degree of sanitary sewage is automatically detected by using a DO controller and the rotating speed of the stirrer is controlled in accordance therewith and, therefore, the exact and continuous treatment is possible; in addition, the running coast is reduced without increasing the size of the device.

摘要： PURPOSE:To eliminate wasteful electric power consumption and to economize costs by permitting free change of the volume ratios and disposition of anaerobic tanks and aerobic tanks and controlling the stirring intensity of an arbitrary number of underwater stirrers in common use for both anaerobic and aerobic treatments according to the purposes of treatments. CONSTITUTION:The underwater stirrers 4 in common use for both the anaerobic and aerobic treatments are installed in the respective sections of plural pieces of partitioned bioreaction vessels 3 so that the stirrers can be converted to either of the anaerobic tanks A or aerobic tanks O in an anaerobic and aerobic activated sludge method. The free change of the volumetric ratios and disposition of the anaerobic tanks A and the aerobic tanks O is permitted so that the anaerobic and aerobic activated sludge treatment can be made. The stirring intensity of an arbitrary number among all the stirrers 4 is controlled automatically and continuously or automatically and intermittently or by a suitable manual operation according to the concn. of the activated sludge in the anaerobic tanks A in consideration for the purpose of the treatment. As a result, the wasteful consumption by the inadequate operation is eliminated and the costs are economized.

摘要： PURPOSE:The high-efficiency underwater aerator consisting of an air feeder coupled to a driving unit, a stirring lift and an air diffuser. CONSTITUTION:When a motor 1 is operated, an impeller 13 revolves to suck air into a box 12 from a pipeline G. This air is sent via air feed line E to an air diffusion rotor 7. The air which has become excess in the rotor is injected into a waste water purifier tank through vent holes 8. On the other hand, a stirring water lift paddle 6 and air diffusion rotor 7 are revolved by a reducer 2 to let the water flow ascend powerfully while finely segmenting and mixing the bubbles.

摘要： PURPOSE:To perform optimum microbiological treatment using only one stirrer by performing purification of filthy turbid water using anaerobic microorganism and purification of filthy turbid water using aerobic microorganism while changing stirring speed for the filthy turbid water to suit to respective purification condition. CONSTITUTION:Sitirring blades 4 for causing circulatory flow are provided pivotally and freely rotatably to the midway of a passage of filthy and turbid water directing to an exhaust port 3 from a suction port 2 of a pressurized chamber 1. A variable speed motor 6 installed with a pole change motor and invertor, etc. capable of freely changing the rotational speed for driving the stirring blades is connected to the shaft center of the stirring blades 4 interposing a reduction gear 5 of a fixed change gear ratio. By operating the motor 6 on an external operating board, the rotational speed of the motor 6 is changed to obtain rotational speed suited to conditions of the quality of the filthy and turbid water.

摘要： PROBLEM TO BE SOLVED: To prevent a carrier from becoming impossible to gravitationally separated due to adhesion of thread-like microbes on the carrier by agitating the carrier in all parts of a biological reaction tank. SOLUTION: A carrier 13 carrying microorganisms together with raw water is made to flow along a bottom face 11a of a biological reaction tank 11 by an underwater agitator 14 installed on the bottom face 11a of the biological reaction tank 11 and is made to flow into an ascending flow path 11e provided along a vertical direction. The raw water flowing into the ascending flow path 11e is subjected to aeration with aerating air through an air feeding pipe 15c of an aerator 15 while being made to move upward and is discharged from an top end of the ascending flow path 11e to an upper part of the biological reaction tank 11. Ammonium nitrogen in the raw water is subjected to oxidation treatment with the microorganisms carried by the carrier 13 while moving upward within the ascending flow path 11e. Water discharged from the flow path 11e is treated to gravitationally separate the carrier 13 in the upper part of the biological reaction tank 11 and is allowed to overflow into an outflow path 11f.

摘要： PURPOSE: To provide an underwater stirring device by which damping of water discharged from a discharge port is controlled and stirring is surely performed in a wide range. CONSTITUTION: When impellers 20 in a pump casing 30 are rotated by a rotary driving mechanism 10, water is sucked into the pump casing 30 and allowed to flow in the axial direction inside the pump casing 30. Water allowed to flow inside the pump casing 30 is introduced into a discharge casing 40 and discharged from a plurality of discharge ports 41 divided in the circumferential direction by the respective partition members 46. Water discharged from the respective discharge ports 41 is divided by the respective partition members 46 and becomes a bundle of water, respectively, and is allowed to flow in a wide range without being damped. When water is discharged from the respective discharge ports 41, water is allowed to flow through guide grooves 45 formed of each partition part 46a of the respective partition members 46, thus, following wakes of water discharged from the respective discharge ports 41 are formed.
