摘 要
煤化工行业作为能源转化和化工生产的重要领域，其废水排放量大且成分复杂，对环境造成严重威胁，因此开发高效、经济的煤化工废水处理技术具有重要意义。本研究旨在针对煤化工废水中高浓度有机物、氨氮及盐分等问题，提出一种集成化处理工艺，并通过实验室小试与中试验证其可行性与稳定性。研究采用高级氧化技术结合生物强化处理方法，辅以膜分离技术，形成多级协同处理体系，有效提升了污染物去除效率。实验结果表明，该工艺可将COD降至50 mg/L以下，氨氮低于1 mg/L，同时显著降低废水中的总溶解性固体含量，满足国家排放标准要求。此外，本研究创新性地引入了微生物群落优化策略，提高了系统抗冲击负荷能力，为实际工程应用提供了技术支持。研究表明，该工艺在处理效率、运行成本及环境友好性方面具有明显优势，为煤化工废水处理技术的发展提供了新思路，也为相关行业的可持续发展奠定了基础。

Abstract
The coal chemical industry, as a critical domain for energy conversion and chemical production, generates large volumes of wastewater with complex compositions, posing severe environmental threats. Consequently, the development of efficient and cost-effective wastewater treatment technologies for the coal chemical industry is of great significance. This study proposes an integrated treatment process targeting high concentrations of organic compounds, ammonia nitrogen, and salinity in coal chemical wastewater, validating its feasibility and stability through laboratory-scale trials and pilot-scale tests. The research employs an advanced oxidation technique combined with bio-enhanced treatment methods, supplemented by membrane separation technology, to establish a multi-stage synergistic treatment system, thereby significantly enhancing pollutant removal efficiency. Experimental results indicate that this process can reduce COD to below 50 mg/L, ammonia nitrogen to less than 1 mg/L, and substantially decrease total dissolved solids in the wastewater, meeting national discharge standards. Additionally, this study innovatively incorporates microbial community optimization strategies, improving the system's resistance to shock loads and providing technical support for practical engineering applications. The study demonstrates that this process offers distinct advantages in terms of treatment efficiency, operational cost, and environmental friendliness, offering new insights into the development of coal chemical wastewater treatment technologies and laying a foundation for the sustainable development of related industries..
