Apparatus for preparing iron-copper bimetallic oxide facilitating liquid medicine feeding

Abstract

The present invention discloses an apparatus for preparing an iron-copper bimetallic oxide that facilitates the feeding of liquid chemical agents. The apparatus includes at least one stage of reaction tanks and sedimentation tanks connected in series; a bottom outlet of a primary reaction tank is connected to a top of a primary sedimentation tank; an alkali liquid storage tank is arranged at an upper part of the primary reaction tank, an iron salt feeding port and a copper salt chemical feeding port are provided on two sides of the primary reaction tank, a stirrer and its stirring paddle are arranged in a middle part of the primary reaction tank, a pH meter and a turbidity meter are installed inside the primary reaction tank; a sludge hopper at a bottom of the primary sedimentation tank is connected to a top of a drying oxidation machine; a bottom outlet of the drying oxidation machine is connected to a top of a grinding device; an overall structure and connection relationship of a secondary reaction tank and a secondary sedimentation tank are the same as those of the primary reaction tank and the primary sedimentation tank, a clarified liquid outlet in an upper part of the primary sedimentation tank is connected to the secondary reaction tank; a clarified liquid outlet in an upper part of the secondary sedimentation tank is connected to the primary reaction tank or to a next-stage reaction tank. The present invention is simple, safe, easy to operate, enables wastewater reuse, and reduces production costs.
