Abstract

The invention discloses a process for pretreating electrophoretic wastewater by microelectrolysis and combination of microelectrolysis. The process comprises the steps as follows: wastewater collection, wastewater treatment, mud-water separation, supernatant filtration, mud treatment and the like, wherein in the wastewater treatment process, chemicals such as a PH regulator, a scale inhibitor, a flocculating agent, a corrosion inhibitor and the like are added, decontamination and non-toxic treatment are performed on wastewater generated by electrophoretic coating by a wastewater conditioning tank, a reaction tank, an intermediate tank and the like, and water-mud separation is achieved, so that water resource pollution caused by direct external discharge generated by electrophoretic coatingis avoided; besides, the system automation degree is high due to the arrangement of a water treatment control device, unattended operation is basically realized, and labor cost is saved.

Description

technical field [0001] The invention relates to the technical field of electrophoresis wastewater treatment, in particular to a process for pretreatment of electrophoresis wastewater by micro-electrolysis and its combination. Background technique [0002] Electrophoretic coating is a special coating film formation method developed in the past 30 years. It has the characteristics of water solubility, non-toxicity, and easy automatic control. It is widely used in industries such as automobiles, electronics, building materials, and hardware. As a result, electrophoresis wastewater is produced and becomes a kind of industrial wastewater that appears widely. This wastewater has the characteristics of many types of pollutants and complex components. [0003] In addition, due to the large differences in the scale of various industries and enterprises, and the large differences in the amount and quality of electrophoresis wastewater, the treatment process of electrophoresis wastewat...
