This study is to change the treatment method of electric-flocculation technology, and the water to be treated enters the electrolysis tank in the form of circulation. Comparison of efficiency and energy consumption by circulating electric-flocculation and ordinary electric-flocculation. Explore the feasibility and energy consumption of the cyclic electric-flocculation method. It is found that the common electric-flocculation method and the cyclic electric-flocculation method have the same removal effect when the copper ion concentration is high, and the effect of voltage on the removal effect is very small; when the copper ion concentration is low, the ordinary electric-flocculation method has better removal effect than the cyclic type. The effect of the removal is good, the voltage has little effect on the removal effect of the common electric-flocculation method, and the effect on the circulation type is greatly affected; as the voltage rises, the limit of the copper ion concentration which is different between the removal effect of the ordinary electric-flocculation method and the circulation type is lowered; Under the same conditions, the energy consumption of ordinary electric-flocculation is always higher than that of the circulating type.
