3种典型污泥处理工艺环境影响分析

Environmental Impact Analysis of Three Typical Sludge Treatment Processes

现行污泥处理工艺主要包括好氧发酵技术、厌氧发酵技术、焚烧技术等。通过列举北京、天津、河北典型污泥处理厂的案例,从采用工艺、可处理最佳污泥种类、处理规模、投资及产生的主要污染物等方面,比较了3种污泥处理技术的环境影响和投资费用等指标,综合考虑优先推荐好氧发酵技术。

The current sludge treatment technology mainly includes aerobic fermentation technology,anaerobic fermentation technology and incineration technology,etc. By listing cases of typical sludge treatment plants in Beijing,Tianjin and Hebei,environmental impact,investment costs and other indicators of three sludge treatment technologies were compared in terms of adopted technology,the best sludge type can be treated,treatment scale,investment and major pollutants produced.Finally,aerobic fermentation technology was preferred for comprehensive consideration
