Micro-electrolytic filler containing catalyst

Abstract

The invention relates to a micro-electrolytic filler containing a catalyst, which comprises ferrum and carbon and is added with a catalyst. The mass percents of ferrum, carbon and catalyst in the filler are 45-55%, 40-50% and 1-5%, respectively. The catalyst is one or more of the following elements: copper, vanadium, molybdenum and antimony. The invention has the advantages that, firstly, the COD de-electrolyzing rate in wastewater which has large concentration of organic matters, high poisonousness and high chromaticity and is hard to treat biochemically is improved by 10-20%, the COD removing rate is about 35-60%, the chromaticity can be removed by 60-90% and meanwhile the B/C value is improved by 0.1-0.3 and biodegradability of the wastewater is improved; secondly, the cylindrical cellular structure of the filler is beneficial to ensure adequate contract reaction of the filler and water to reduce the flowing resistance of the water; and thirdly, the carbon bed is not easy to passivate and harden and be blocked by iron mud, and the amount of sludge is reduced.

AI Technical Summary

Benefits of technology

This new method described for treating refractories (refrigeration) was developed that overcomes these technical disadvantages such as low concentrations of harmful substances or strong oxidants found during manufacturing processes. It also improves its effectiveness due to improved treatment efficiency caused by an increase in surface area per unit volume compared to previous methods without this improvement. Additionally, it reduces the pressure drop across the system while still maintaining good fluid circulating properties. Overall, this innovative approach provides better environmental benefits through efficient use of resources.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving the performance or cost savings associated with treating highly concentrated industrial waters containing heavy metals such as chromium (Cr) compounds. Iron carbon electrodes have been found to be effective at removing these contaminants from treated streams but they can become less efficient when exposed repeatedly over multiple cycles due to their poor durability against oxidative damage caused during use.
