Background

At present, the main methods for treating high-concentration organic/high-salt industrial wastewater are a triple-effect evaporation method and an incineration method. The incineration method has the advantage of high removal rate of COD, but the tail gas in the incineration process, such as dioxin and the like, needs to be treated, and the treatment is difficult and the treatment cost is high. The triple effect evaporation method has the advantage of low energy consumption. However, the process produces concentrated water and sludge that require further crystallization or drying. In order to solve the defects of the technology, the field of sewage treatment is newly created by spraying wastewater treatment.

The spray method is used for treating high-concentration organic/high-salt industrial wastewater, and has the advantages of low energy consumption and capability of directly drying organic matters and salt into granular substances. The process is as follows: spray drying the high-concentration organic/high-salt industrial wastewater, collecting particles formed after spray drying, recovering evaporated moisture and gasified volatile organic compounds in the spray drying, and condensing the water and the gasified volatile organic compounds into liquid to be discharged. Before the spray drying treatment, some toxic substances which are difficult to biodegrade need to be oxidized and decomposed by using a strong oxidant so as to reduce the pollution degree, wherein the treatment process is mainly Fenton (Fenton) reagent treatment.
