AI Technical Summary

Technical Problem

The existing magnetic separation and treatment of black and odorous water bodies lack effective devices to ensure full mixing between magnetic powder and black and odorous wastewater, resulting in poor purification effect.

Method used

A device including a reaction unit, a magnetic powder recovery unit and a wastewater precipitation unit is designed. The reaction unit ensures sufficient mixing of magnetic powder and wastewater by setting up a coagulant mixing chamber, a magnetic powder mixing chamber and a coagulant mixing chamber, and combining with a stirring device. The magnetic powder recovery unit uses a rotating magnetic roller and scraper mechanism to recover magnetic powder from wastewater. The wastewater precipitation unit improves the sedimentation effect of wastewater by setting up a water barrier plate and an anti-impact plate.

Benefits of technology

By fully mixing magnetic powder and wastewater, the purification effect of black and odorous water bodies is significantly improved, the recycling rate of magnetic powder is increased, the wastewater treatment cost is reduced, and the precipitation effect is improved.

Abstract

The utility model relates to the technical field of wastewater treatment, and discloses a device for treating black and odorous water through magnetic separation, which comprises a reaction unit, a magnetic powder recovery unit and a wastewater precipitation unit which are sequentially arranged, the reaction unit comprises an equipment box, and a feeding hole is formed in one end, far away from the magnetic powder recovery unit, of the equipment box; the equipment box is sequentially provided with a coagulant mixing bin, two magnetic powder mixing bins and a coagulant aid mixing bin, stirring devices are arranged in the coagulant mixing bin, the two magnetic powder mixing bins and the coagulant aid mixing bin, and vertically staggered circulating holes are formed between every two adjacent coagulant mixing bin, the two magnetic powder mixing bins and the coagulant aid mixing bin. By arranging the two magnetic powder mixing bins and the stirring device, wastewater sequentially passes through the coagulant mixing bin in which the coagulant is added, the two magnetic powder mixing bins in which the magnetic powder is added and the coagulant aid mixing bin in which the coagulant aid is added, so that sufficient mixing between the magnetic powder and the wastewater is ensured, and the purification effect on the wastewater is improved.
