Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to electrochemical flocculation circulating water treatment equipment. Background Art

[0002] Electroflocculation is a method of sewage treatment. The reaction principle of electroflocculation is to use aluminum, iron and other metals as anodes. Under the action of direct current, the anode is dissolved to produce Al, Fe and other ions. After a series of hydrolysis, polymerization and ferrous oxidation processes, it develops into various hydroxyl complexes, polynuclear hydroxyl complexes and even hydroxides, so that the colloidal impurities and suspended impurities in the wastewater are condensed and precipitated for separation. At the same time, the charged pollutant particles swim in the electric field, and part of their charge is neutralized by the electrode, which promotes their destabilization and precipitation. When the wastewater is subjected to electrolytic flocculation treatment, it not only has a coagulation and precipitation effect on the colloidal impurities and suspended impurities, but also can remove a variety of pollutants in the water due to the oxidation effect of the anode and the reduction effect of the cathode.

[0003] However, when the existing electrocoagulation method is used to treat sewage, there will still be a lot of water in the flocculent material during the removal process. This part of water has not been fully purified. If the sewage flocculent material containing sewage is directly discharged, it will cause secondary pollution. This requires the separated flocculent material to be dehydrated. The existing electrocoagulation method for treating wastewater lacks the dehydration function of the flocculent material.

[0004] Therefore, those skilled in the art provide an electrochemical flocculation circulating water treatment device to solve the problems raised in the above background technology. Utility Model Content
