等の問題点があった。However, according to the above-mentioned conventional display means, the turbidity of the treated water gradually increases as approaching the sludge interface. Also, the relationship between depth and turbidity is displayed incrementally. Therefore, it is difficult to clearly identify the position (depth) of the sludge interface at a glance, and a slight error often occurs between the depth of the sludge interface read from the display unit and the actual depth of the sludge interface. . Specifically referring to FIG. 4, the graph shown in FIG.
The vertical axis represents the depth and the horizontal axis represents the turbidity.However, the shape of the sludge interface is gradually increasing even near the rapid increase in turbidity, which indicates the sludge interface. It is difficult to read accurately, and the bending point indicating the sludge interface is often read in a range (a) that is shifted back and forth from the actual depth, and there is a problem that an error occurs during that time.
