<p>PROBLEM TO BE SOLVED: To facilitate equipment management and to make the addition of a flocculant to follow the fluctuation of sewage flow quantity by driving a sewage pump and a flocculant injection pump linked with each other. SOLUTION: A sewage A is introduced into a treating tank 3 from a sewage tank 2 provided with the sewage pump 1 by the sewage pump 1. On the other hand, the flocculant B is injected by the flocculant injection pump 4. In such a case, the driving of the sewage pump 1 and the flocculant injection pump 4 are linked with each other. That is, for example, both pumps 1, 4 are completely linked with each other to drive the flocculant injection pump 4 to add the flocculant B to the treating tank 3 when the sewage pump 1 is driven. By the structure, the maintenance and management of the equipment is facilitated, the addition of the flocculant is made to follow the fluctuation of the sewage flow-in quantity to stabilize the treatment.</p> |
