苏中某工业园区废水深度处理案例分析

苏中某工业园区污水处理厂设计规模30 000 m/d,接纳电子,光伏等难处理废水,因水质成分复杂,出水标准严苛,拟构建"改良AAO+MBR+深度处理"工艺以实现对该工业区废水深度处理.改良AAO通过厌氧—缺氧—好氧—后缺氧四段式生化反应提升脱氮效能,深度处理采用"臭氧催化氧化—高效沉淀—反硝化滤池"组合工艺.根据2024年实际运行结果显示,CODCr,NH3-H,TP,氟化物均值分别达到11,0.23,0.02,2.83 mg/L,均显著优于地表"GB 3838-2002"Ⅳ类水标准;出水TN浓度为2.9 mg/L,满足"GB 18918-2002"一级A标准.部分出水回用于道路浇洒和厂区绿化等,剩余出水经生态安全缓冲区进一步净化处理.项目为同类工业废水处理提供了"生物强化+深度处理"的示范方案.

浙江某工业园区强夯法处理地基的事故分析

对浙江某工业园区1#厂房强夯法处理地基的事故原因进行分析,并提出该场地独立承台和场地地面的加固措施.分析表明,1#厂房表层填土厚度差异性较大,且场地较深处存在着相对软弱下卧层,强夯法的加固深度有限,加之局部区域夯击能不足,是造成1#厂房强夯法地基处理事故的主要原因.因此,对于同一土层厚度差异较大且深处有相对软弱下卧层的场地,不宜单独采用强夯法处理地基.为控制场区内独立承台的沉降,将1#厂房所有独立承台纠正到统一标高后,可补桩加固该场地的独立承台.对于场地地面,可采用直接灌水泥浆的方法来消除较厚填土层发生的工后沉降.

苏中某工业园区废水深度处理案例分析

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.
