Coking wastewater can be reused in the circulating water system to achieve near-zero emissions
Thread Content
The coking wastewater from Jilin Jianlong Steel’s coking plant is reused in the circulating cooling water system after ammonia evaporation treatment. After a month of trial operation, inspections of the heat exchangers showed excellent results: the existing scaling issues were disappearing, and wastewater discharge was reduced to near zero.
One month isn’t enough to draw any conclusions; there are factors of randomness and other variables at play. Let’s wait and see the results after six months or a year – if it continues to operate stably, then that would represent a revolutionary breakthrough in wastewater and circulating water treatment.
Our technology has been applied in the treatment of coking wastewater in 10 projects to date; the earliest one is Shanxi Lubao Coking, where it has been in use for a year. The Tangshan Dafeng coking project has also been in operation for 10 months and is still running now. I have detailed operational data for Tangshan Dafeng Coking, and I will upload it once I’ve organized it. The file is quite large; you can tell me your email address.
What are the results after ammonia vapor treatment? There are over a dozen indicators in the circulating water system – can all of them be met?
Could you send me your technical documents as well as the operational data of the coking plant currently in use to my email? We could also work together for promotion. 35828597@qq.com. Thank you!
Is the coking wastewater directly reused in the circulating cooling water system after ammonia evaporation treatment, without undergoing biochemical treatment? Is there oil in the water?
I work in coking and hope to get your information. Thank you. LZW0615@163.com
A small amount of oil in coking wastewater is not a problem; it is best to install an oil removal device at the inlet to the circulating water system.
The last edit to this post was made by Learn with an open mind * the boy on 2018-2-28 at 12:36. Ammonia-containing wastewater can be directly treated using recycled cooling water; if this method can operate stably, it would represent a technological revolution in the treatment of coking wastewater. I admire those who know such techniques. Could you provide some technical materials for me to study? Thank you
The information above is true; I am also a worker responsible for wastewater treatment at a coking plant. Please send the relevant documents to my email address: 517978217@COM
