ECPD electrolytic air flotation complete equipment

Abstract

The invention discloses ECPD electrolytic air flotation complete equipment. The ECPD electrolytic air flotation complete equipment comprises an upper cylinder, a lower cone and an inner cylinder, wherein a residue scrapping device is mounted at the top of the upper cylinder, the inner cylinder is located inside the upper cylinder, an electrode plate assembly is arranged between the upper cylinderand the inner cylinder, a YS air purging device and a water backwashing device are mounted at the lower part of the electrode plate assembly, the inner cylinder has a closed lower part and an unsealedupper part, an efficient releaser is arranged at the lower part of the inner cylinder, a water yielding device is further fixed to one side of the upper part of the upper cylinder, and a liquid levelregulator and a water outlet are mounted on the water yielding device. The ECPD electrolytic air flotation complete equipment integrates the functions of electrolyzed flocculation, precipitation andefficient air flotation and is simple in structure, small in floor area and convenient in operation, and colloidal and suspending pollutant substances are effectively removed from water; and the ECPDelectrolytic air flotation complete equipment has a good removal effect on emulsified oil, macromolecular organic matters, microbes, heavy-metal ions, chloride ions and turbid and part of colored substances, the B / C ratio of sewage is increased, and a powerful guarantee is provided for subsequent advanced sewage treatment.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a complete set of electrolytic air flotation equipment. Background technique [0002] With the rapid development of social production in our country, the awareness of environmental protection has been greatly improved, and various sewage treatment technology and equipment technology have achieved faster development. [0003] At present, electrolytic flocculation is a water treatment process that uses soluble metal anodes to flocculate metal hydroxides produced during electrolysis to remove pollutants in water. In reality, the anode material is usually made of easily available and cheap metals such as aluminum and iron. The hydroxide precipitate generated by electrolysis has good flocculation and adsorption properties, and can effectively remove pollutants from wastewater. At the same time, the hydrogen and other gases precipitated at the cathode during elect...
