摘要： PROBLEM TO BE SOLVED: To provide a pH reduction method for a secondary treated water of sewage which reduces the treatment cost for pH reduction of the secondary treated water, and improves safety in treatment operation therefor. SOLUTION: The secondary treated water of sewage is aerated with a carbon dioxide-containing gas, so that carbon dioxide in the gas is dissolved in the water. Thereby, the concentration of hydrogen ion (H + ) in the secondary treated water of the sewage is increased to reduce the pH of the secondary treated water. As a result, the pH of the secondary treated water of the sewage can be reduced by the carbon dioxide-containing gas without using a pH adjuster such as sulfuric acid used in conventional methods, which enables reduction of the equipment cost for pH reduction treatment and of the running cost, and improves the safety of the treatment operation.

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.
