摘要： PURPOSE: To provide a water treatment tank fitted with panel-shaped filter bed capable of performing filter bed assembling work outside the tank. CONSTITUTION: Beam members 11 are provided to the upper regions in a water treatment tank 20 and a large number of frame members 9 having through-hole parts and panel-shaped filter beds 1 are successively hooked with the beam members 11 from an insertion port 24 to be suspended in the tank 20. A terminal ring 15 is fixed to the inner surface region of the tank 20 opposed to the through-hole parts of the frame members 9 of the tank 20 at the time of the suspension from the beam members 11. The leading end of the attaching rope 7 delivered into the tank 20 from the insertion port 24 is passed through the terminal ring 5 and folded back to be returned to the outside of the tank. Hollow distance pieces 13 are interposed between the through-hole parts 10 of the mutually adjacent frame members 9 and between the terminal ring 15 and the through-hole parts of the adjacent frame members 9 from the rear end of the attaching rope 7 to send the frame members 9 into the tank 20. The terminal of the rope 7 and the leading end passing through the distance pieces 13 and the through-hole parts to be folded back through the terminal ring 15 of the rope 7 are connected without loosening the rope to fix the frame members to the terminal ring 15.

摘要： PURPOSE:To increase the speed of a waste water treatment by hermetically communicating the waste water-microorganism mixture in a bioreaction vessel to a centrifugal separator, separating the mixture to a thickened liquid and clean liquid and hermetically returning the thickened liquid from the centrifugal separator to the bioreaction vessel. CONSTITUTION:The treated water in the liquid mixture 3 in the centrifugal separator 23 shifts to the clean liquid 25 and the greater part of the bacteria therein remain in the thickened liquid 24 and, therefore, the liquid 24 contains the bacteria at a high concn. The bacteria in the liquid 3 sent first to the centrifugal separator 23 by a circulation pump 22 are thickened and are returned to the bioreaction vessel 20 when the liquid 24 is returned to the vessel 20. The clean liquid 25 is discharged as treated water 6 through a water sealing device 26 in an ordinary operation. However, the liquid 25 is fed into the vessel 20 through a liquid level control valve 27 when the water level L in the vessel 20 is lowered by a decrease in the inflow rate of the waste water 1, etc.

摘要： PURPOSE:To remarkably improve dephosphorizing and denitrifying actions and to reduce the cost of equipment by agitating sewage while introducing it and thereafter performing batch type sewage treatment wherein aeration treatment is performed under control of the concn. of dissolved oxygen. CONSTITUTION:After agitating sewage while introducing it, the following batch type sewage treatment is performed wherein the concn. of dissolved oxygen (DO) is controlled at 2-3ppm and aeration treatment is performed. In this case, it is preferable that precipitation and discharge of treated water are performed after the combination of both introduction of sewage, agitation and aeration is repeated at two or more times. Further a sewage storage equipment of a front stage and a pumping equipment for introducing sewage can be made small by continuously introducing sewage at an anaerobic time divided into several times. Furthermore, since DO control can be performed by intermittent operation of a blower, the operation time of the blower is shortened and energy saving can be contrived.
