Treatment Effect of Electroplating Wastewater Treatment Technology for Electric Heating Tubes

2. On the basis of adopting a flat flow structure, the air flotation tank is equipped with 5 sediment buckets to remove the accumulated mud at the bottom of the tank. When the connecting pipe of the dissolved air release device enters from the top, it causes a dead corner for the scraper to scrape the mud. Simultaneously adopting a new PV type non clogging release device

3. Filtration and PH value callback: the water in the middle water tank is pressurized to the mechanical filter (sand filter) with multi-layer fillers for filtration, which traps impurities and further clarifies the water. The PH value after treatment generally exceeds 9. The pH meter is used to control the solenoid valve to automatically add acid and adjust the PH value back to 6-9, so as to overcome the error caused by manual control and ensure that the outlet water quality is stable and up to standard.

Wastewater Treatment Technology 3 Treatment Effect

Many manufacturers have achieved stable and compliant emissions after more than a year of operation.

4. Conclusion

The integrated process of chemical flocculation and air flotation is used to treat electroplating comprehensive wastewater with ideal results. The effluent quality is stable and meets the standard, and the treatment effect on zinc, other heavy metal ions, and petroleum is particularly good. The removal rate is as high as 95% -98%, and COD can also be effectively removed. The pH value is controlled between 6-9, and other pollutants can also meet the discharge requirements.

⑵ The comprehensive wastewater treatment process has a simple structure, convenient operation, stable effect, low investment, and good promotion value.

The treated wastewater meets the national secondary discharge standard and 65% of the treated water can be recycled and used to flush stains on the production line and the company's internal toilets. How to further try and reuse after processing is a problem that should be considered.

After dehydration, the pollutants contain a large amount of heavy metals such as zinc and copper, as well as organic matter. In the absence of comprehensive utilization conditions, they should be carefully disposed of to prevent secondary pollution.
