治污产污是难免的，但一定是建立在两害相权取其轻的基础上，否则就得不偿失。党的十八大以来，我 国从解决突出生态环境问题入手，注重点面结合、标本兼治，已经实现由重点整治到系统治理的重大转 变。具体到污染治理工作，也已经跃升到系统治理，既不仅要统筹协同治理气、液、固态的污染物，还 要探索低成本可持续的深度治理方案。 比如旋流混合式烟气治理技术可以做到尘、硫、硝一体脱除，其将燃煤锅炉渣槽中已有的氧化钙和氧化 镁（碱性物质）分别用作脱硫剂、脱硝剂，"以废治废"的方式不仅成本低而且效果好。近期垃圾焚烧行 业转移式烟气治理技术的效果也得到了验证，其利用吸收吸附技术将烟气中的污染物转移至吸收液中， 将旧工艺中需要超短时间内高成本化学方法的烟气污染物脱除，转变为对无机污水的从容处理，不仅拉 升了烟气超低排放的标准，还大幅降低了烟气深度治理的成本。 实践证明，深度治污，真正的"深度"不在于技术方案的简单堆叠与标准数值的无限加码，而在于对治理 链条的整体洞察与物质转化的全局优化，在统筹气、液、固协同治理的系统视角下，追求成本可控、效 果可靠、环境效益与经济效益共赢，找到打破"治污产污"困局的创新之路。 污染治理如今几乎覆盖了所有生 ...
