A combined process of ammonia distillation - evaporation concentration - supercritical water gasification (SCWG) supercritical water oxidation (SCWO) was proposed for coking wastewater treatment. The NH3 in wastewater was first recovered in ammonia distillation section. The deammoniated wastewater was concentrated in the evaporation concentration section, in which the quantity of the wastewater was decreased accordingly. Then the concentrated wastewater entered into the SCWG section to produce the syngas such as H2, CO, CH4, and liquid effluent entered into SCWO section, where the pollutants were completely degraded. The operation parameters of the combined process were simulated by Aspen Plus software and the investment and the operation cost were also analyzed. For a wastewater of 5000kg/h, the investment of the combined process is 6000000 ¥. The profit from byproduct of ammonia, syngas and steam is 70¥/t. For the whole process, it can gain a profit of 5.1 ¥/t (wastewater).

Supercritical Water Oxidation (SCWO) is a unique environmentally safe technology being widely used in industrial wastewater treatment for its remarkable superiority of removes organic matters efficiently. Characteristics of supercritical water, fundamental principle and flow sheet of SCWO were introduced. Meanwhile, application situations of SCWO in different fields of industrial wastewater treatment were presented in detail, the existing problems in its application were pointed out. At last the prospect for the development of SCWO was also proposed.

Presents the result of testing a hybrid wastewater treatment method with contaminants of organic nature, in particular, effluents of pharmaceutical enterprises. The method combines reagent-membrane concentration of aqueous solutions and the subsequent oxidation of organic components at supercritical water parameters. Primary concentration is based on the introduction into solution of sorption materials of organic nature and microfiltration of the resulting suspension using ceramic membranes. It is shown that supercritical water oxidation of concentrates reduces their COD to the level acceptable for discharge.
