APPLICATION OF BIOLOGICAL CARBON IN DEEP PURIFICATION OF TAIL WATER OF URBAN SEWAGE TREATMENT PLANTS
-
摘要: 为探讨城镇污水处理厂尾水的深度净化技术,以农林秸秆生物质发电后的废料制成的生物质基材为填料,考察填料对城镇污水处理厂尾水的处理效果,并借助Miseq高通量测序技术对移动床生物膜反应器(MBRR)中的悬浮填料,多孔生物质基材中生物膜的微生物群落组成和结构进行了解析。结果表明:多孔生物质基材能够深度净化市政污水处理厂尾水,对MBBR出水NH4+-N、TN、COD和TP的平均去除率分别提高了0.9%、19.0%、7.1%和10.5%。此外,由于多孔生物质基材的微生物物种丰度和多样性高于MBBR,其微生物群落结构中反硝化相关菌属占优势(24.2%),并含有一定比例的聚磷菌(4.6%)和自养硝化菌(1.3%),因此多孔生物质基材更利于脱氮除磷等功能菌群的富集和生长,可对污水的强化处理起关键作用。该结果可为城镇生活污水处理厂尾水深度净化过程中强化脱氮除磷的工程化应用提供依据和参数。

Abstract: To study the deep purification technology of tail water of urban sewage treatment plant, the biological carbon made from the waste of agricultural and forestry straw biomass power generation, was used as the filler to investigate the treatment effect of tail water of urban sewage treatment plant. Miseq high-throughput sequencing technology was also applied to study the microbial community structures of suspended packing in the moving bed biofilm reactor (MBBR) and biological carbon filler. The results showed that biological carbon could deeply purify the tail water, and the average removal rate of NH4+-N, TN, COD and TP was higher than that of effluent from sedimentation tank by 0.9%, 19.0%, 7.1% and 10.5%. The microbial species richness and diversity of biological carbon filler were higher than those in MBBR, and denitrification related bacteria in the microbial community was dominant species(24.2%). In addition, phosphorus accumulating bacteria (4.6%), and nitrifying bacteria (1.3%) related genera were detected in the biofilm samples. The results suggested that biological carbon filler was conducive for the enrichment and growth of functional bacteria like nitrogen and phosphorus removal bacteria and played a key role in wastewater treatment. This study could provide a scientific basis and parameters for biological carbon in engineering application. -
