电力行业作为大气污染物的排放大户，每年烟尘、SO2、NOx等污染物的排放量巨大。为控制污染物排放，燃煤电厂陆续进行超低排放改造，烟气协同治理技术和“环保岛”思想应运而生。本文从“环保岛”技术的不同技术路线入手，对不同路线的设备和工艺流程进行分析，通过具体实例验证“环保岛”技术的实用性。

As a large emitter of atmospheric pollutants,power industry produces huge amount of soot,SO2,NOx and other pollutants every year.To control pollutant emissions,coal-fired power plants have been transformed into ultra-low emission ones.Smoke co-control technology and the idea of "environmental protection island" came into being.This paper starts from the different technical routes of "environmental protection island" technology,analyzes the equipment and process flow of different routes,and verifies the practicability of "environmental protection island" technology through some specific examples.
