Statistics on the Application of Advanced Treatment Processes for Coking Wastewater
Thread Content
Dear friends, I would like to ask what specific treatment processes are being used for the advanced biological treatment of coking wastewater under the current pressure of environmental regulations How effective is it? Can it stably meet the GB16171-2012 standard? Everyone, please share your thoughts right away. Thank you :'(:'(
After biochemical treatment, the COD is below 250; by adding chemicals for coagulation and flocculation, it can be reduced to below 80
After biochemical treatment, the COD is below 250; by adding chemicals for coagulation and flocculation, it can be reduced to below 80
Direct membrane application (ultrafiltration + reverse osmosis? ) That won’t work; in this way the membrane will get clogged and contaminated easily, and its operation won’t be stable
The biochemical effect is a bit poor; can it really be reduced to below 80 just through coagulation?
Has anyone used advanced oxidation processes? Talk about the effects
After passing through the secondary sedimentation tank, the COD level of the biochemical effluent drops to around 250; we then add chemicals in the subsequent coagulation tank, and after flocculation and sedimentation, the COD level of the effluent falls below 80.
What medicine? Coagulant? That way, the standard is met; it seems quite easy
The composite coagulant independently developed by our company results in a water treatment cost of 3–7 yuan per ton (based on the volume of water discharged from the secondary sedimentation tank); the exact cost needs to be determined through pilot tests.
