With the rapid development of industry, the discharge of wastewater containing heavy metals has been increasing, posing a serious threat to the environment and human health. Wastewater containing heavy metals mainly comes from the production processes of mining, electroplating, metallurgy, chemical industry and other industries. This type of wastewater cannot be directly discharged or treated in the biochemical stage. The metal elements in it need to be extracted for reuse.
Treatment method for heavy metals wastewater containing nickel copper
There are many methods for treating heavy metal wastewater. The most commonly used method is solvent extraction, and the equipment used is CWL-M centrifugal extractor.
One of our customers is engaged in metal powder production. During production, a large amount of heavy metal wastewater is generated. The customer hopes to extract and recycle the metal elements in it. We have arranged technical engineers to develop a plan for the customer, using solvent extraction. Under certain conditions, a complex reaction occurs with the extractant, and the metal ions are extracted from the aqueous phase to the organic phase, and then back-extracted to the aqueous phase under alkaline conditions, so that the solvent is regenerated for recycling.
Extraction equipment for treatment of heavy metals wastewater containing nickel copper
The CWL-M series centrifugal extractor produced by Zhengzhou Tiei Extraction is a newly developed equipment. It not only has a novel appearance, but also has continuously innovative technology. This type of extraction equipment has the following performance advantages:
- The experimental results show that the COD removal rate in wastewater is as high as 96%, and the extraction efficiency is high.
- The extraction cost is low. Compared with other methods, the cost of solvent extraction is relatively much lower.
- The power consumption is even smaller, only 1/10-1/3 of the traditional model.
The centrifugal extractor is very effective in treating heavy metals wastewater containing nickel copper. Our Tiei Extraction have developed such treatment plans for many companies, and the results are very satisfactory to customers. If you want to know more details, welcome to consult us.
