Treatment of high-salt and high-concentration organic wastewater has become a bottleneck restricting green and sustainable development of the fine chemical industry. Aimed at the problems of wastewater treatment, such as large discharge, complex pollutant composition, high salt, high toxicity, poor biodegradability, difficult treatment and high cost, and difficulty in disposing of crystalline waste salt, this paper summarizes the harmless treatment technologies for high-salt and high-concentration organic wastewater, including the harmless treatment technology for organic matter, desalination technology, and related integrated technology, and predicts the development trend of the harmless treatment technology for high-salt and high-concentration organic wastewater in the fine chemical industry.
