A flocculant dosing device for metallurgical wastewater treatment

Abstract

The invention relates to the technical field of wastewater treatment, in particular to a flocculant dosing device for treating metallurgical wastewater, comprising a wastewater pool, a medicine injection cylinder for injecting flocculant into the wastewater pool fixedly installed on the outer bottom of the wastewater pool, a medicine cylinder for preparing flocculant liquid arranged on the top of the medicine injection cylinder, a support box fixedly installed on the top of the medicine cylinder, a feeding assembly for intermittently feeding the medicine cylinder arranged inside the support box, a buffer pool fixedly installed on the top of the medicine cylinder of the wastewater pool, the invention achieves sufficient and thorough contact and mixing of flocculant liquid and metallurgical wastewater by cooperating with a swing cylinder and a mixing plate on an arc-shaped movable plate of a dispersion disk in the buffer pool, and utilizes the arc-shaped movable plate to cooperate with a first hole and an auxiliary hole to disperse and inject material into the buffer pool, with large flow, fast stirring and large flocculant liquid injection amount, and small flow, slow stirring and small flocculant injection amount, thereby adaptively improving the contact time and stirring degree of flocculant liquid and metallurgical wastewater.
