精细化工行业高盐、高浓度有机废水无害化处理现状及发展趋势

Status quo of high-salt high-concentration organic wastewater treatment in fine chemical industry and its development trend

精细化工行业高盐、高浓度有机废水的治理问题已成为制约精细化工行业绿色可持续发展的瓶颈问题。针对精细化工行业废水具有排放量大,污染物成分复杂,高盐、高毒、可生化性差,治理难度大及成本高,结晶废盐无处置去向等瓶颈问题,综述了精细化工行业高盐、高浓度有机废水无害化处理技术,包括有机物无害化处理技术、脱盐技术及相关集成技术,预测了精细化工行业高盐、高浓度有机废水无害化处理技术发展趋势。

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 highconcentration 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 highconcentration organic wastewater in the fine chemical industry.
