链条锅炉改造为循环流化床镐炉的点火及运行技术

链条锅炉改造循环流化床锅炉后,锅炉点火及燃烧调整方式较以前完全不同,介绍由链条锅炉改造为循环流化床锅炉后的点火与运行,提供一种经济的、可操作性强的改造循环流化床锅炉的点火技术-杠炭过渡床点火法;提出了改造的循环流化床锅炉在点火运行中需要注意的问题,希望给大家借鉴。     

用表面活性剂提高生物滴滤床净化废气中氯苯的性能

A laboratory-scale trickling biofilter column,filled with Raschig rings and inoculated with Pseudomonas putida (ATCC 1785)was used to purify chlorobenzene contained waste gases.Sodium dodecyl sulfonate(SDS)was used to enhance the performance of trickling biofllter.Purification performance of the trickling biofilter was examined for chlorobenzene inlet concentration of 1.20～5.04 g/m~3 at different EBRTs between 76～153 s.Without SDS addition,with simultaneous increase in chlorobenzene inlet loading rate and gas flow rate,100% removal efficiency was achieved at EBRT of 109 s and inlet loadings below 5120 mg/m~3.Addition of SDS to nutrient solution led to improvement of trickling biofilter purification performance. By introducing 25 mg/L SDS,the removal efficiency was increased by 21% and elimination capacity up to 234 g/(m~3.h)was achieved at chlorobenzene inlet loading of 241 g/(m~3.h).Although SDS concentration experienced a low rate reduction after continuous nutrient solution recirculation,this result has little influence on trickling biofilter's removal efficiency in monitoring period.     

不同基质及植物组合的表面流湿地净化试验研究

试验通过静态试验研究了不同基质及植物组合床对水体中CODcr、氨氮、TN等污染物的净化效果,并对其净化机理进行了初步研究。试验发现,不同基质和不同植物组合对湿地的净化效果具有较大影响,可能与基质的组成、结构反应以及植物的生理生化等特性有关。
