The utility model discloses a coking wastewater zero release processing system, include the leading preprocessor, distillation concentrator and the high temperature high pressure degradation ware that connect gradually through the pipeline, the distillation concentrator passes through the pipeline and links to each other with circulating water pond, leading preprocessor internally mounted has stirring separator and jetting separator, the distillation concentrator is including the distillation column and the heater of integrative installation, distillation entry, distilled water export and concentrate export have been seted up on the distillation column, distilled water export through the pipeline with circulating water pond links to each other. The utility model discloses a coking wastewater zero release processing system, heavy oil, light oil in the waste water are detached through the physics mode to leading treater, the distillation concentrator passes through the low-grade heat source in the production technology, and separation waste water obtains the normal water and reaches the more waste water of high concentration, high temperature high pressure degradation ware is degraded to the concentrating spent liquor and is made fertilizer, makes coking wastewater recycle, reaches the waste water zero release.
