摘要
自江苏常州成功开发电厂燃煤锅炉以掺烧方式处置污水厂污泥以来,国内许多地区都因投资小、占地少、运行成本低廉、排放达标且符合相关产业政策的先进"协同处置"工艺而积极推广。然而,因该工艺稀释排放极其严重,折算后污泥焚烧特征污染物二噁英等严重超标,对环境和人们健康的隐性影响和长期影响十分严重,综合分析得出弊远大于利,应该坚决摒弃。
Since the"successful development"of co-firing of sludge in the coal-fired power plant in Changzhou, Jiangsu Province,the sewage sludge has been properly treated. Many power plants in other regions of China have started to follow the"successful"example of this development and apply the technique in their coal-fired boilers.This advanced"cooperative disposal"technique is considered to be costsaving, less land use, and more economic. It also helps the plant to ensure a higher compliance rate of emission standards and other relevant industrial policies. Especially in recent years, the massive application of this technique in power plants all the over the country, presents a trend of "a single Spark makes a great fire"However, this technique can generates the severe dilution discharge of, sludge incineration characteristic pollutants such as dioxins,which are seriously exceeded the pollution standard index, The discharge of these pollutants will raise long-term damage to the environment and cause negative effect to public health. After comprehensive analysis of the impact,this technique should not be allowed and banned by the.
