生物土壤除臭技术在渗沥液A/O系统中的应用
|
摘要
从进一步提升区域环境要求考虑,对生活垃圾焚烧发电所配套的渗沥液处理站A/O系统O池进行除臭技术改造。通过对O池密封加装玻璃钢盖板阻止恶臭气体外溢,采用离心风机吸气收集形成O池内微负压,废气通过集气管路输送至生物土壤除臭系统。生物土壤除臭技术利用微生物分解恶臭组分机理,O池恶臭废气经生物土壤滤池处理后稳定达到GB 18918—2002城镇污水处理厂污染物排放标准废气厂界Ⅱ级排放标准要求。
Considering the further improvement of regional environmental requirements,the deodorization technology of A/O system O pool of leachate treatment station of domestic waste incineration power generation was improved.FR P cover plate was installed on the sealing of O pool to prevent the overflow of odorous gas. A micro negative pressure was formed in the O pool by centrifugal blower,and then the foul gas was transported to the biological soil deodorization system through the gas gathering pipeline. Microorganism was used by biological soil deodorization technology to decompose the foul gas component.The foul gas of O pool treated by biological soil filter reached second level discharge standard at boundary of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918—2002).
