21世纪经济报道记者雷椰 李德尚玉 北京报道 12月26日，生态环境部举行12月例行新闻发布会。 建设用地土壤污染问题一直是社会关注的焦点。21世纪经济报道记者在会上获悉，"十四五"以来，全国 土壤环境质量发生基础性变化，风险得到有效管控。生态环境部有效保障重点建设用地安全利用，严格 名录地块管理，推动近1万个企业腾退地块实施污染管控，保障重点建设用地安全利用，指导1226个地 块完成修复并移出名录。启动实施长江沿线1公里化工腾退地块土壤污染专项治理行动。 （生态环境部例行新闻发布会现场 官方供图） 赵世新表示，下一步，生态环境部坚持守牢底线和支撑服务并重。严控腾退地块风险，有序推动污染地 块安全高效再利用，助力城市更新和高质量发展。 建设用地土壤环境质量关系居民的生活品质和条件。如何才能有效保障建设用地安全利用，为"住得安 心"筑牢土壤环境安全屏障？生态环境部土壤生态环境司司长赵世新主要以下几个方面介绍： 一是严格名录监管。落实土壤污染防治法规定，列入建设用地土壤污染风险管控和修复名录的地 块，"不得作为住宅、公共管理和公共服务用地""禁止开工建设任何与风险管控和修复无关的项目"，累 计将2630余个地块纳 ...

落实《国民经济和社会发展第十四个五年规划和2035年远景目标纲要》要求，我们聚焦土壤和地下水污 染突出问题，上下联动，确定企业类74个和耕地类50个共计124个土壤污染源头管控项目。坚持高位推 动，压实各方责任；以中央资金为牵引，带动民间资本深度参与；建立全流程质控机制，严把设计关、 施工关和成效关；强化示范引领，推广一系列典型经验。目前，124个项目全部完成。 四是激发企业内生动力。推广管道非开挖修复、储罐声发射检测等典型技术，为企业提供实践指导， 3400余家企业主动实施绿色化改造。 一是消除一批土壤环境风险隐患。企业类项目每年可管控5497.8万吨含有毒有害物质物料泄漏风险。耕 地类项目每年减排含重金属颗粒物191.3吨，有效管控4.7万余吨废渣重金属污染风险。 每日经济新闻："十四五"国家规划纲要将"实施100个土壤污染源头管控项目"列入国家102项重大工程之 一。请问该重大工程进展成效如何？ 二是构建三位一体技术路径。推广管线架空建设，实现渗泄漏"可视化"；创新池中池、池中罐等复合防 护"双保险"技术；构建涵盖渗漏监测装置和地下水监测井的渗漏"早发现"系统，形成"可视化—双保险 —早发现"技术路径。 ...
