In the neutralization treatment tank (3), when only normal washing wastewater is used, the injection of a secondary flocculant can generate metal hydroxides with an appropriate concentration, which is the core of the flocculating action, and then proceed to the next step. By injecting the secondary flocculant into the flocculation treatment tank (5), 70 flocs of appropriate concentration are grown, and the next precipitation treatment can be performed satisfactorily. 1. However, when a concentrated waste liquid (containing raw waste acid and dissolved metals) is mixed into the washing wastewater, an unusual agglomeration phenomenon occurs. In other words, if the neutralization treatment is carried out properly in the neutralization treatment tank (3) (neutralization time will be longer because the pH is low and the metal content is high), the dissolved metal will form metal hydroxides, which will cause a flocculation effect. When combined with the metal hydroxide produced by the secondary flocculant, an excessive amount of metal hydroxide is produced, which increases the SS concentration in the flocculation treatment tank (5) and further increases the settling tank (5).
6), so by visual inspection of the floc concentration in (34) of the block cause in Figure 4 and beaker test of the floc concentration in (35),
(36) Temporarily stop operation of the coagulant chemical injection pump by manual operation, and restart the same pump by manual operation after the floc concentration reaches a certain level or less, that is, after the floc concentration reaches a certain level or less, that is, after the pump is used only for normal cleaning waste water. Start again.

It is necessary to carry out flocculation treatment, and if a carryover of 70% occurs through the gap, problems such as turbidity and deterioration of water quality will occur, or the flow rate will decrease due to clogging of the clarifying filter. There was a decline. In addition, there were problems such as economic losses due to power consumption and the use of chemicals due to the backwashing process of the turbidity and clogging equipment.

凝集処理、沈殿処理を行なうことができる。Next, the effect will be explained. In the case of normal washing wastewater only, the content of dissolved metals in the wastewater is low, and the production of metal hydroxides, which are the core of the coagulation effect, is low, so it is natural that the coagulation treatment tank (5
) has a small SS concentration, and SS concentration meter (30) #: t, -
A sequence circuit (3) is connected to the next flocculant injection pump (17)
1) continues to output an electric signal to start operation, that is, to turn ON,
-The injection of the next flocculant has the function of supplementing the generation of metal hydroxide, which is the core of flocculation, and the SS6 degree of the flocculation treatment tank (5) can be maintained within an appropriate range, resulting in good flocculation treatment. A precipitation treatment can be performed. In addition, if concentrated waste liquid (mainly tiger acid) is mixed into the cleaning wastewater, if it is neutralized within the appropriate pH range in the neutralization treatment tank (3), it will contain a large amount of dissolved metals, and this alone will cause the coagulation effect. The amount of metal hydroxide produced is large, and when combined with the amount of metal hydroxide produced by the second flocculant, it becomes too much, and the flocculation treatment tank (
5) SS concentration increases and exceeds the upper limit within a certain range, and S
S@Kokana (30) is a chemical injection pump (17) for -order flocculant
through the sequence circuit (31).
By continuing to output the FF electric signal and stopping the injection of the secondary flocculant, the generation of metal hydroxide, which is the core of flocculation, is suppressed, and the SS concentration in the flocculation treatment tank (5) is lowered within the appropriate range, resulting in a good condition. Coagulation treatment and precipitation treatment can be performed.
