High-pressure electrochemical wastewater treatment equipment

Abstract

The invention relates to wastewater treatment equipment, and particularly relates to high-pressure electrochemical wastewater treatment equipment. The high-pressure electrochemical wastewater treatment equipment is simple in structure; wastewater treatment time is short through improvement of the material and the structure and the energy utilization efficiency is improved. The high-pressure electrochemical wastewater treatment equipment comprises an equipment body (1), a tank body (2), a plurality of anode plates (3), a plurality of cathode plates (4), a water inlet (7) and a water outlet (8), wherein the tank body (2) is arranged in the equipment body (1); the anode plates (3) and the cathode plates (4) are in composite layers; a plurality of through holes (5) are formed in the anode plates (3) and the cathode plates (4); an aeration tube (12) is arranged in the tank body (2) and is provided with a rubber sleeve (13); the rubber sleeve (13) sleeves on the outer wall of the aeration tube (12) and is tightly clung to the outer wall of the aeration tube (12); and a plurality of air outlet parts (14) comprising air outlet holes (15) are arranged on the rubber sleeve (13).

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to high-voltage electrochemical sewage treatment equipment. Background technique [0002] At present, the sewage formed by industrial production contains a large amount of heavy metal ions, such as the washing water of plating parts in electroplating plants, and the dust removal and drainage of non-ferrous metal smelters. However, the heavy metal contained in the wastewater to be treated is not a single type, and often a variety of heavy metals coexist. These heavy metal ions pose a great threat to the environment. [0003] When treating wastewater containing heavy metals, if the metal ions released by the anode plate do not diffuse into the water body in time, the plate is prone to polarization and passivation, resulting in long sewage treatment time, high energy consumption, and insufficient release of active substances. Uniformity, high moisture content of dross and poor operation c...
