Wastewater sources: rinsing of plated parts, discharge of waste plating solution, leakage and spillage caused by improper workshop operations, self-use water discharge during wastewater treatment process, and laboratory water discharge. Rinsing wastewater from plated parts constitutes the main component of electroplating wastewater, with its discharge accounting for at least 80% of the total wastewater discharge from electroplating workshops.

Water quality characteristics: Rich in toxic and harmful components such as heavy metal ions, cyanide, and organic pollutants; based on its characteristics, various treatment methods are often used for combined purification, mainly including physical methods, chemical methods, biological methods, and membrane separation technology. Core treatment technologies: electroflocculation technology, bioaugmentation technology.

Electroflocculation technology

The technical principle of electroflocculation equipment in treating electroplating wastewater is based on electrochemical principles. It involves the dissolution of anode metal, which combines with hydroxide ions generated by water electrolysis to form hydroxide precipitates. Additionally, oxidation and reduction reactions during the electrolysis process effectively remove pollutants from the wastewater.

Biological fortification technology

Bioaugmentation technology enhances the treatment capacity of the biochemical system by adjusting the technical parameters of traditional biochemical processes and incorporating four biological agents: double-activated COD-removing bacteria, double-activated denitrifying bacteria, biological enzyme detoxifier MN, and biological enzyme growth promoter BN. This allows the organic matter, ammonia nitrogen, total nitrogen, and total phosphorus in the effluent to be degraded and meet emission standards through low-cost biochemical methods.

1. Stable treatment process: Ensure the treatment process maintains stable operation under varying water quality and flow conditions;

2. Low operating costs: No need to add a large amount of chemical agents, reducing agent costs and thus operating costs;

3. Low sludge production: Compared to chemical oxidation, it reduces the sludge volume by approximately 40%, alleviating the pressure on subsequent sludge treatment;

4. Green and pollution-free: No new pollutants are introduced during the treatment process, and no secondary pollution is caused to the water body;

5. Organic matter oxidation and sterilization: Effectively remove organic matter from wastewater, serving the purpose of sterilization and disinfection;

6. Chromaticity reduction: Through electrochemical reduction, pigment molecules are reduced to colorless substances, thereby removing the chromaticity from wastewater;

7. High degree of intelligence and smartness: Utilizing advanced automatic control systems, it can achieve remote monitoring and automatic adjustment of equipment.
