Urgent! Advanced treatment of coking wastewater
Thread Content
I would like to ask the experts: Our company plans to install a system for advanced treatment of coking wastewater. We require that the treated water be suitable for reuse in cooling cycles, with COD levels of ≤20 mg/L and ammonia nitrogen levels of ≤5 mg/L. Are there any examples of such systems in use in China? What process to use? How is the processing effect? Thank you!
The combination of ultrafiltration and reverse osmosis yielded good results in the initial stage, but the operating costs over a long period were too high, and there were high requirements regarding suspended solids in the wastewater resulting from biochemical processes
Ultrafiltration plus reverse osmosis is too costly, and coking plants have a large volume of water flow. Tie Xiong has invested over 200 million. Let’s first take a look at the current quality of the water. The original poster can get in touch with me to discuss this together
I attended a lecture like this before the New Year; some companies claimed to be able to do this for the reuse of circulating water, and that the recycling rate could be increased by more than 10 times, but the cost was too high
Tangshan Zhongrun Coal Chemical Industry has installed advanced wastewater treatment systems; the investment was around 30 million yuan. The operating costs are not high, and it seems that the treatment efficiency is good. The membranes need to be replaced every two years, at a cost of about 2 million yuan
