| abstract | To appropriately remove the phosphorus component in sewage and to ensure good water quality by appropriately controlling the amount of flocculant or acetic acid added to the biological water treatment apparatus. To do. A biological water treatment apparatus flows out of an infusion pump 9 for adding a drug to a biological reaction tank 1 into which sewage flows, an aeration apparatus 4 attached to the biological reaction tank 1, and the biological reaction tank 1. An aeration apparatus having a settling basin 5 for precipitating the mixed liquid, a return sludge pump 7 for returning the precipitated sludge to the biological reaction tank 1, and an excess sludge extraction pump 6 for extracting the precipitated excess sludge When at least one of the aeration amount by No. 4, the return sludge amount by the return sludge pump 7 and the excess sludge extraction amount drawn by the excess sludge extraction pump 6 reaches the upper limit value or the lower limit value, a chemical addition start signal is output. To do. [Selection] Figure 28 |
