The Example of High Salinity Coking Wastewater Reclamation and Reuse Project
Abstract:
The high salinity coking wastewater is a poor biodegradability, extremely complex composition and refractory industrial wastewater after biochemical treatment, which is difficult to achieve reuse standards by conventional processing method. A coking plant used advanced treatment (micro-electrolysis, Fenton) and desalination (electrodialysis, ultrafiltration, reverse osmosis) to treat coking wastewater after biochemical treatment. The effluent quality achieved stability and better than the required quality indicators of reclaimed water of “Code for design of industrial recirculation cooling water treatment” (GB50050-2007). The concentrated water was sent to mining company to comprehensive utilization, which achieved near zero emissions.
