Bacterial populations and their roles in a pharmaceutical-waste anaerobic filter

The bacterial populations, their roles and distribution in an anaerobic filter treating a simulated pharmaceutical effluent containing a branched-chain fatty acid (BCFA) were studied. The BCFA degradation pathway and mechanisms were also investigated. The biofilm from the filter was enriched in serum bottle cultures using different BCFAs and fatty acids as the sole carbon source. The anaerobic biofilm was a consortium of (1) BCFA-degrading Syntrophomonas spp. which produced ethanoic acid and H₂, (2) H₂-utilizing Methanococcus spp. and (3) ethanoate-utilizing Methanothrix spp. Beta-oxidation was proposed as the acidogenic mechanism. The bacterial consortium could degrade BCFAs with tertiary carbon but not those with quaternary carbon. Branching at the alpha or beta position along the carbon chain interfered with the beta-oxidation mechanisms. Bacterial distribution in the filter was uneven, which was attributed to incomplete mixing.

Methanogenic granular sludge as a seed in an anaerobic baffled reactor

This paper reviews the importance of phase separation in anaerobic wastewater treatment, characteristics of anaerobic baffled reactor (ABR), properties of anaerobic granular sludge, granulation process and advantages of granular sludge over nongranular sludge. The performance data of ABR and its modified configurations with regard to carbonaceous matter removal by using various seed sludges are compared. It is concluded that enhanced wastewater treatment efficiencies can be achieved with methanogenic granular seed sludge in an ABR because of a number of advantages associated with granular biomass over nongranular aggregates.     

微量元素对ABR发酵产氢产甲烷的影响

为构建厌氧折流板反应器(ABR)发酵联合产氢产甲烷系统,考察了微量元素对ABR系统前端格室发酵产氢、后端格室发酵产甲烷的影响。在进水COD为6 000 mg/L、碱度为1 900 mg/L的条件下,当未投加微量元素时,系统对COD的去除率为51%,产氢能力为0.46 m3/(m3.d),产甲烷能力为0.68 m3/(m3.d),四格室的厌氧污泥脱氢酶活性均较低;而在相同运行条件下,当投加微量元素后,系统对COD的去除率提高到62%以上,产氢能力为0.37 m3/(m3.d),产甲烷能力达到1.66 m3/(m3.d)。研究表明,投加微量元素可有效刺激ABR发酵联合产氢产甲烷系统中厌氧污泥的活性,由于ABR中产甲烷菌等耗氢菌群活性的增强导致发酵产氢作用受到抑制,但产甲烷活性的进一步增强,使系统的处理效能得到明显提高。     

Methanogenic bacteria adhered to solid supports

Adhesion of methanogenic bacteria and acidogenic bacteria to solid supports has been studied by using various solid materials. Three kinds of bacteria slurries were prepared for the experiments. These were cultured by feeding them acetic acid, an acid mixture and a mixture of glucose and pepton respectively. Test specimens were submerged into the bacteria slurries for different periods of time. The overall process of biofilm development was divided into 3 phases: induction, accumulation and dynamic balance between production and shearing. The quantity of adhered biomass varied with the characteristics of the solid supports. Bacteria adhered to the moderately rough surfaces that have pores measuring a few tenths of a micron in diameter more than the polished surfaces and rough surfaces and preferably adhered to the solid supports made of carbon material. The formation of the biofilm depends not only on the characteristics of the bacteria and fluid regimes but also on the characteristics of the solid supports.
