日前，在江苏省农业面源污染治理培训会上，南通如皋市分享的农田排灌系统生态化改造"农田退水治 理"项目经验成为全场焦点。如皋依据2023年度断面水质状况和水系特征，将汛期水质不能稳定达标的 重点国考省考断面及敏感水体周边农田作为试点，启动2024年度农田排灌系统生态化改造。项目覆盖8 个镇区，涉及两万余亩农田，已实现农田退水的高效治理与循环利用，为面源污染治理提供了可复制的 样板。 如皋经验的核心，在于精准把握"退水不直排、肥水不下河、养分再利用" 的治理原则。这一理念并非 简单的污染拦截，而是将农田退水视为可循环利用的资源。当地依托地形特点，将低洼地改造为肥水收 集调蓄池，构建起"雨季储水防污染、旱季灌溉再利用"的闭环系统。同时，在高标准农田建设中融入生 态化改造，通过生态塘对汛期过量退水进行分级净化，既减少污染物排放，又实现水资源的高效利用， 真正做到变废为宝。 两大关键举措直击农田退水治理要害。在秸秆处理上，如皋市以"四离一集中"原则划定秸秆离田区域， 通过建立秸秆收储运体系和综合利用产业链，将田间废弃物转化为生物质燃料、有机肥原料，从源头上 阻断秸秆腐烂对水体的污染。针对肥料使用，联合科研机构探索化肥减 ...

Group 1 - The core viewpoint of the news is the introduction of new regulations aimed at standardizing administrative inspections related to enterprises, ensuring they are conducted legally, fairly, and efficiently [1][2] - The new regulations emphasize the necessity of approval and notification for inspections, transitioning from arbitrary checks to a systematized approach that curtails impulsive inspections by local enforcement [1][2] - The regulations prohibit unauthorized entities from conducting inspections, ensuring that only legally designated bodies have the authority to perform such checks, thereby eliminating issues like "temporary workers conducting inspections" [1] Group 2 - The introduction of standardized documentation, including the inspection approval form and notification letter, aims to balance the power of inspections with the rights of enterprises, allowing companies to assert their rights during inspections [2][3] - The shift from "extensive management" to "refined governance" is highlighted, with clearer standards and documentation reducing opportunities for power abuse and enhancing transparency in the inspection process [2][3] - The implementation of a dynamic evaluation mechanism for documentation and the establishment of a case library for typical enforcement scenarios are intended to improve the efficiency and effectiveness of environmental inspections [3]

Group 1 - The core viewpoint of the news is the release of the "National Plan for China's Implementation of the Montreal Protocol on Substances that Deplete the Ozone Layer (2025-2030)", which outlines actions for phasing out ozone-depleting substances (ODS) and hydrofluorocarbons (HFCs) in China over the next six years [1][2] - The plan aims to fulfill international environmental obligations and guide the development of a sustainable ecological civilization [1] - The fire protection industry in China has already made significant progress in phasing out high ODP fire extinguishing agents since 2010, showcasing the country's commitment to global environmental governance [1] Group 2 - With the full implementation of the Kigali Amendment, China will freeze HFCs production and usage at baseline values of 1.853 billion tons CO2 equivalent and 0.905 billion tons CO2 equivalent starting in 2024, with a target to reduce these values by 10% by 2029 [2] - The fire protection industry faces new challenges in HFCs reduction, and the National Plan sets clear compliance targets and lifecycle management measures to support green development [2][3] - There is a need to enhance research and development of new clean and efficient fire extinguishing technologies, as suitable alternatives to HFCs are currently lacking [3] Group 3 - Strict monitoring of halon and HFCs production and usage is essential, along with the development of recycling technologies [4] - Although halon is banned for controlled use, its recovery and regeneration are allowed, and HFCs will soon face production and usage controls [4] - The establishment of a recovery network for extinguishing agents and support for purification and regeneration processes are crucial for reducing costs and extending the use of existing stocks [4] Group 4 - The National Plan provides a policy framework, but further refinement of supporting rules and technical standards is necessary to promote the application of new clean and efficient fire extinguishing technologies [5] - The industry should develop a phased action plan for HFCs alternatives and provide policy incentives for units adopting environmentally friendly fire extinguishing systems [5] - Demonstration applications of new technologies in certain regions can create replicable models for the industry [5]

Core Viewpoint - The Chinese government is intensifying regulations on vehicle emissions, particularly focusing on heavy-duty trucks, to combat air pollution and improve air quality, as these vehicles are significant contributors to PM2.5 levels in major cities [1][2]. Group 1: Regulatory Measures - The Ministry of Ecology and Environment and nine other departments have issued stricter regulations on vehicle emissions, particularly targeting heavy-duty trucks, by incorporating random inspections into daily regulatory plans [1]. - The new guidelines emphasize the need for compliance from manufacturers, owners, users, and service providers, promoting a collaborative approach to ensure environmental responsibilities are met [4]. Group 2: Emission Statistics - In 2023, nitrogen oxide emissions from trucks reached 3.872 million tons, accounting for 83.7% of total automotive emissions, with heavy-duty trucks alone contributing 3.5 million tons [1]. - Despite a 15% reduction in nitrogen oxide emissions from mobile sources since the implementation of pollution control measures, violations of emission standards remain prevalent among vehicle owners [2]. Group 3: Compliance Challenges - Many vehicle owners are circumventing regulations by tampering with emission control systems, leading to increased pollution and potential vehicle damage, as the costs of repairs can exceed the expenses of compliant operation [2]. - The inconsistency in enforcement across regions allows non-compliant vehicles to evade penalties, with some owners believing the likelihood of being caught is low, resulting in repeated violations [3]. Group 4: Enforcement and Incentives - The newly released inspection guidelines aim to standardize the inspection process for heavy-duty diesel and gas vehicles, enhancing the capacity of local enforcement agencies [4]. - A differentiated management approach will be trialed, allowing compliant heavy-duty trucks to be exempt from certain inspections, thereby encouraging adherence to environmental regulations [4].

我国精炼铜的产能位居世界第一，但受资源禀赋限制，每年需要大量进口铜精矿。2022年我国精炼铜产 量1053.4万吨，占全球总量的41%，其中原生铜冶炼约占70%。当年进口铜精矿2532万吨，对外依存度 达80%。目前铜产量仍不能达到国内铜消费水平，铜冶炼产能会进一步扩张，铜精矿缺口将继续扩大。 为充分利用海外铜精矿资源，保障原料供应，促进我国铜冶炼降本提质，2019年以来，海关总署已先后 批准5家企业在港口保税区开展进口铜精矿混矿业务（即"保税混矿"），就是将来自海外的超标铜精矿 与洁净矿在保税区内进行物理混匀，混合达标再报关，经检验合格后输送至国内铜冶炼企业。 我国《关于公布进口铜精矿中有毒有害元素限量的公告》对进口铜精矿中砷（As）元素限量规定不得 大于0.5%，比国际上的限值标准（通常为0.2%，例如日本和美国）高0.3%。因此，扩大铜精矿的进口 存在一定的环境隐忧。 铜精矿中的砷在高温下挥发进入烟气、造渣进入炉渣，烟气中砷部分收集在白烟尘，剩余进入制酸系统 的污酸中，经中和处理进入产出的炉渣中。最终约0.06%的砷随废气排放，0.04%的砷进入成品硫酸， 99.9%进入含砷固废。砷污染物一旦进入环境， ...
