Abstract
A near-zero-release treatment system and method for high concentrated organic wastewater is in the chemical engineering and environment protection field, whose core technology is SCWO. The wastewater and sludge are grinded by the homogeneous pump, pressurized by high-pressure plunger pump, transported to successive pipeline for preheating and mixing with the oxygen and undergoes SCWO reaction in the reactor. After pressure release in the pressure relief device, the reacted fluid passes through the self-cleaning filter and gas liquid separator for insoluble solid and gas separation; then enters the MVR for crystallization of the soluble salts to realize near-zero-release of the feeding. The regular water treatment technology (coagulation sedimentation, membrane biotechnology, membrane technology, etc.) is adopted to complement SCWO, which lowers the operating parameters of the reactor and cuts the operating cost by treating the remaining COD with regular water treatment technology.
