腐殖土活性污泥技术中的填料研究

Study on Pellets of Humus Soil Activated Sludge Process

腐殖土活性污泥技术处理污水能力更强、效率更高,本文通过对这项技术的核心——腐殖土填料进行改进,采用岩相法、X-光射线衍射、差热分析、化学分析等技术手段,用腐殖土、硅藻土和浮石进行配比,制成腐殖土填料,提高了有机物、营养盐类的去除率,使BOD的去除率达95%以上,TN、TP去除率达70%以上。从根源上消除硫化氢、氨氮等恶臭物质,污泥产率减少30%以上,解决了污泥的二次腐化和处理难的问题。

Humus soil activated sludge technology ability is stronger, more efficient, this article through to the core of the technology - the humus soil packing was improved, the petrographic method, X-ray diffraction, differential thermal analysis, chemical analysis and other technical means, with humus soil, the ratio of diatomite and pumice, packing into humus soil, improve the removal rate of organic matter and nutrient salts, make the BOD removal rate over 95%, TN and TP removal rate above 70%, and from the source to eliminate the stench material such as hydrogen sulfide, ammonia nitrogen, reduce sludge yield more than 30%, solved the secondary sludge decay and deal with difficult problems.
