The automatic valve is generally used to regulate the flow of sludge, and when an automatic valve malfunctions, a manual valve is alternatively used.

Generally, when fine solids precipitated in the first settling tank 410 and the second settling tank 430 are caused to flow to the second settler sludge discharge pipe 412, the valves 481, 482, and 483 of the valves are opened, So that the solid material flows to the tertiary sludge discharge pipe 111 through the second settling tank sludge discharge pipe 412. When it is not necessary to flow the fine solid matter into the second settling tank sludge discharge pipe 412, all the valves 481, 482 and 483 are closed. In the conventional sludge treatment process, the manual valves are maintained in the open state, and the flow of the sludge is controlled by opening and closing the automatic valve.

In addition, valves 471 and 472 are also provided on the third settling tank discharge pipe 413. The valves are opened and closed to allow the wastewater to flow from the second settling tank 430 to the advanced treatment tank 440. When the wastewater treatment capacity of the advanced treatment tank 440 is exceeded, the valves 471 and 472 are opened, The wastewater containing the substance flows to the third sludge discharge pipe 111 through the third settling tank discharge pipe 413. The provision of two valves 471.472 on the third settling tank discharge pipe 413 can be used to regulate the flow of the micro solid material-containing wastewater as the other valve when one valve is not operated properly or becomes inoperable It is for this reason. Here again, reference numeral 471 denotes a manual valve, and reference numeral 472 denotes an automatic valve, which normally controls the flow of wastewater containing micro solid matter as an automatic valve. The other manual valve is prepared in case of an abnormality in the automatic valve.
