１の底部に凝集沈澱し、上部には上澄水が分離される。Now, when removing emulsified oil from wastewater, the wastewater treatment agent is introduced into the reaction tank [1] by the wastewater treatment agent input device 14 or directly by manual input, and the reaction tank stirring example 15 is operated to remove the wastewater from the wastewater. Disperse and mix the processing agent. Next, A
The A chemical solution is injected by the M solution injection pump 7 until the indication on the PH meter indicator 17 detected by the PH meter detection section 16 in the reaction tank 1 changes to a predetermined constant PH value, and then the B chemical solution is injected. The chemical solution in the tank 3 is injected into the reaction tank 1 until it reaches a predetermined pH value, and then the C chemical solution is similarly injected into the reaction tank 1. During the above operation, the stirrer 15 is operated continuously or intermittently. As a result of these treatment operations, the emulsified oil in the wastewater becomes a )O-lag shape and coagulates and precipitates at the bottom of the reaction tank 1, and supernatant water is separated at the top.
