Electric floating wastewater treatment system and electric floating wastewater treatment method

Abstract

The invention discloses an electric floating wastewater treatment system and an electric floating wastewater treatment method. The system comprises a main cavity body, an electrode device, a residue scraping device, a dosing device, a cleaning device and a control device; an adjustable graphite electrode plate group is arranged in an electrode tank, the adjustable graphite electrode plate group comprises a plurality of graphite electrode plates stacked at intervals, cushion blocks clamped between the adjacent graphite electrode plates and adjusting screws for connecting the graphite electrodeplates, and every graphite electrode plate is provided with one or more first connecting hole and a plurality of reaction holes for easily generating microwave bubbles, so the contact reaction area between the graphite electrode plates and wastewater is greatly extended, the reaction rate and the reaction effect are improved, many micro-bubbles are formed, and the particle adhesion effect is good;and the electrode device, the residue scraping device, the dosing device, the cleaning device and the control device are arranged, so the automatic running of the electric floating wastewater treatment system is realized, the running reliability of the whole system is ensured, and the wastewater treatment efficiency and the purification effect are improved.

Description

technical field [0001] The invention relates to the technology in the field of water treatment, in particular to an electrical floating wastewater treatment system and an electrical floating wastewater treatment method. Background technique [0002] As a water treatment process, air flotation has been widely used in the treatment of various industrial wastewater and urban domestic sewage. At present, for oily wastewater, etc., air flotation is usually used to remove scum and slick oil. For example, the treatment of oily wastewater in petrochemical and machinery manufacturing can also be used as a wastewater pretreatment method to remove wastewater that is difficult to remove through precipitation. Suspended substances such as colloids to improve the subsequent treatment performance of wastewater. The air flotation method is to form highly dispersed micro-bubbles in water and adhere to solid or liquid particles in the wastewater to form a water-air-particle three-phase mixed...

AI Technical Summary

Problems solved by technology

The existing electrolytic air flotation technology has some limitations that are difficult to break through, such as: not enough bubbles, unsatisfactory processing efficiency, large power consumption, high operating costs, etc.
