Experience Exchange on Wastewater Treatment in Coal-to-Gas Production
Thread Content
Our company uses the coal slurry methanol production process, with an annual output of 200,000 tons of methanol. The wastewater treatment process is IMC, with a flow rate of 50 m3/h. The normal treatment cycle lasts approximately 7 hours (1.5 hours for water intake, 3 hours for aeration, 1 hour for sedimentation, and 1.5 hours for water discharge). For advanced treatment, an \"ultrafiltration + reverse osmosis\" process is used with water reuse, but the biochemical treatment efficiency for wastewater remains poor. Please share your company’s experiences regarding the wastewater treatment processes for coal-based gas, so that more people can learn and improve!
What causes poor biochemical parameters and fluctuations in water inflow volume and quality?
Mainly, it’s because the wastewater treatment staff here are not familiar with this process.
The best approach then is training, namely relatively professional training that includes skills related to operation and judgment
