新华社天津12月15日电（记者徐思钰、高敬）正在进行的第三轮第五批中央生态环境保护督察15日 通报典型案例，指出天津宁河、蓟州等区部分湿地未得到有效保护，自然保护区内违规问题多发，矿山 修复治理工作不严不实。 督察组发现，天津部分湿地保护缺位。宁河区桥北街道震新村湿地内倾倒有建筑垃圾，并混有除尘 布袋等工业固体废物，侵占面积约6亩。湿地水质监测结果显示，化学需氧量、氨氮浓度分别超地表水 环境质量Ⅲ类标准14.6倍、1.7倍。宁河区天驹建筑材料有限公司将约21亩湿地排干，用于建设厂房和物 料堆场。场地内露天堆存大量废旧栏杆等物料，因除锈喷漆作业，地面已被染成黄色。蓟州区张毕庄村 南侧一处湿地堆填大量建筑垃圾，填埋量约7.2万立方米，侵占湿地13.5亩。 自然保护区内违规问题多发。今年9月，督察组暗查发现，在天津古海岸与湿地国家级自然保护区 缓冲区的曾口河附近，有施工单位违规占用和破坏滩涂作为设备堆场，还将约2800立方米建筑垃圾倾倒 在附近坑塘。宁河区俵口镇设在保护区实验区内的生活垃圾中转场环境管理混乱，场内生活垃圾露天堆 存，场外建筑垃圾和生活垃圾随意倾倒。11月督察发现，上述保护区缓冲区内的北淮淀镇乐善庄村 ...

Core Viewpoint - The article emphasizes the importance of implementing the "Ecological Environment Protection Supervision Work Regulations" to enhance ecological supervision at the provincial level, focusing on key areas such as emission reduction, ecological protection, and long-term governance improvements [1][2][3]. Group 1: Key Focus Areas for Supervision - The supervision will focus on three main combinations: reducing emissions while increasing green development, preserving existing ecological resources while promoting new growth, and addressing immediate environmental issues while establishing long-term governance frameworks [1][2]. - Specific areas of supervision include structural emission reductions, management of major engineering projects, and enhancing biodiversity protection through integrated ecological management [1][2]. Group 2: Collaborative Supervision Approach - The article outlines a systematic approach to supervision that includes regional collaboration, departmental coordination, and a closed-loop feedback mechanism to ensure effective implementation of ecological policies [2][3]. - For instance, in Jiangsu Province, the supervision will address both local pollution issues and the overall health of the ecological system in significant river basins [2]. Group 3: Strengthening Support Measures - To enhance the effectiveness of supervision, the article highlights the need for improved institutional frameworks, team capacity building, and the use of advanced monitoring technologies [3]. - This includes refining work procedures for inspections, providing training for inspection personnel, and utilizing satellite and drone technologies for better problem detection [3].

Core Insights - The central ecological environment protection inspection team has identified significant issues in the urban sewage collection and management in Wuzhong City, Ningxia Hui Autonomous Region, leading to untreated sewage discharge into the Yellow River [1][2] Group 1: Environmental Issues - Wuzhong City has a total of 510 kilometers of drainage network, of which 402 kilometers are combined rain and sewage systems, with no progress on the required separation reform [1] - During the rainy season from 2023 to 2024, there were 23 instances of sewage overflow, with the first sewage treatment plant discharging approximately 1.2 million cubic meters of sewage into the Yellow River, exceeding surface water quality standards significantly [2] - The concentrations of chemical oxygen demand, ammonia nitrogen, and total phosphorus in the discharged sewage were 15.3 times, 21.7 times, and 20.5 times higher than the Class III surface water quality standards, respectively [2] Group 2: Management and Infrastructure - The inspection team pointed out that the management of urban environmental infrastructure in Wuzhong City is inadequate, with responsibilities for sewage collection network construction not being fulfilled [2] - There were multiple instances of sewage overflow from the second and third sewage treatment plants, with the second plant discharging around 360,000 cubic meters and the third plant nearly 100,000 cubic meters into the Yellow River [2] - The inspection team will conduct further investigations and ensure follow-up inspections are carried out as required [2]
