Electroplating wastewater treatment equipment

The main source of zinc in electroplating and metal processing industry wastewater is the drag liquid from electroplating or pickling. The contaminants are transferred to the rinsing water through the metal rinsing process. The pickling process involves immersing the metal (zinc or copper) in a strong acid to remove surface oxides, and then immersing it in a brightener containing strong chromic acid for a brightening treatment. The wastewater contains a large amount of hydrochloric acid, heavy metal ions such as zinc and copper, and organic brighteners, which are highly toxic. Some of them also contain highly toxic substances that are carcinogenic, teratogenic, and mutagenic, and are extremely harmful to humans. Therefore, electroplating wastewater must be recycled and treated carefully to eliminate or reduce its pollution to the environment.

Electroplating wastewater treatment adopts the electrolysis treatment process within iron filings. This technology mainly uses activated industrial scrap iron filings to purify wastewater. When the wastewater comes into contact with the filler, electrochemical reactions, chemical reactions and physical effects occur, including catalysis , oxidation, reduction, replacement, co-precipitation, flocculation, adsorption and other comprehensive effects to remove various metal ions in wastewater and purify the wastewater.

Product application fields
1. Treatment of boiler feed water, industrial high-purity water, pharmaceutical pure water, food water, etc.
2. Municipal sewage and community water must be discharged after biochemical treatment to meet standards and then be reused after intensive treatment.
3. Treatment and reuse of industrial wastewater such as circulating water, cooling water, reinjection water, and collected water from petroleum, chemicals, steel plants, electroplating, printing and dyeing.
4. Milk concentration, protein concentration, enzyme product concentration, starch recovery, electrophoresis paint recovery, vinegar clarification.
5. Treatment of mineral water, purified water, food and beverage water, tap water, and rural drinking water.

Usage: It is suitable for enterprises whose various indicators in electroplating wastewater seriously exceed standards or have certain reuse requirements for wastewater.
Process introduction
The water reuse process of the first-grade non-clogging membrane is to add a reverse osmosis treatment system after the first-grade worry-free chemical precipitation process. Through the removal of heavy metal ions, etc. by the reverse osmosis membrane, < br/> Various water quality indicators in the effluent are far below the limits of the new standards, and wastewater is reused with a reuse rate of above, responding to the national call for energy conservation and emission reduction. Our company uses world-class anti-fouling membrane materials, coupled with reasonable design and careful maintenance, which can effectively alleviate the problem of membrane fouling.
