.工业领域是我国污染物和碳排放产生的主要领域,2022年中山市创新性提出"环保共性产业园"的建设设想,是工业领域减污降碳协同增效一次积极的探索.本研究通过收集我市某工业园区环评报告,废水处理设施技术方案等资料,对环保共性产业园减污降碳协同控制的情况进行分析研究,并提出下一步发展建议.通过数据比对发现,环保共性产业园因产能上升,生产废水,SO_(2)和NO_(x)以及危险废物的排放量均呈现上升趋势,但COD,颗粒物,VOCs污染物排放量下降.经计算,园区年碳排放量为9.11万吨,碳排放主要来自天然气燃烧的直接排放.后续建议园区要在整体布局,技术创新以及运行管理方面应采取更积极主动的措施,以实现减污降碳协同增效.浙江某工业园区强夯法处理地基的事故分析

A wastewater treatment plant in an industrial park in Central Jiangsu Province has a design capacity of 30 000 m/d, accepting electronic, photovoltaic, and other refractory industrial wastewater. For this complex industrial wastewater, an integrated process-"improved anaerobic-anoxicoxic (AAO) membrane bioreactor (MBR) advanced treatment"-was developed to achieve advanced treatment performance. The improved AAO process enhances nitrogen removal efficiency through a four-stage biochemical reaction (anaerobic-anoxic-aerobic-post-anoxic), while the advanced treatment employs an integrated process: "ozone catalytic oxidation–high-efficiency sedimentation–denitrification filter tank. " Actual operation results in 2024 showed that the average concentrations of chemical oxygen demand (CODCr), ammonia nitrogen (NH3-N), total phosphorus (TP), and fluoride were 11, 0.23, 0.02, and 2.83 mg/L, respectively-all significantly better than Class IV standards of the Surface Water Environmental Quality Standard (GB 3838-2002). The average effluent total nitrogen (TN) concentration was 2.9 mg/L, meeting Class 1A standards of the Pollutant Discharge Standard for Urban Wastewater Treatment Plants (GB 18918-2002). A portion of the effluent is reused for road sprinkling and plant greening, while the remaining effluent undergoes further purification via an ecological safety buffer zone. This project provides a "Biological Enhancement Advanced Treatment" model scheme for treating similar industrial wastewater.
