研究了接种量、初始pH和烟碱负荷对构建假单胞菌HF-1生物强化系统处理烟草废水的影响。结果表明，HF-1菌生物强化系统的最佳条件为：接种量1.10 mg/g（HF-1菌干重/活性污泥干重），初始pH 7.0，烟碱负荷250-1000 mg/L。高于1.10 mg/g会导致菌株HF-1在活性污泥中的非定殖和该生物强化系统的建立失败。pH大于8.0时，HF-1菌株在活性污泥中的定殖受到抑制。即使HF-1菌株在pH高于8.0时在活性污泥中定殖，但由于活性污泥中细菌的低活性，烟碱和总有机碳（TOC）的去除受到抑制。烟碱负荷对生物强化系统的启动没有抑制作用，但当烟碱负荷超过1000 mg/L时，生物强化系统对TOC的去除能力受到抑制。本研究为生物强化系统处理烟草废水的工程应用提供了重要的参数。
This study evaluated and optimized the influence of inoculum amount, initial pH, and nicotine load on the construction of Pseudomonas sp. HF-1 bioaugmented system for tobacco wastewater treatment. The results demonstrated that the optimum condition for the set-up of strain HF-1 bioaugmented system was 1.10 mg/g (dry weight of strain HF-1/dry weight of activated sludge) of inoculum amount, initial pH 7.0, and 250–1000 mg/L nicotine load. Higher than 1.10 mg/g could lead to noncolonization of strain HF-1 in activated sludge and failure of set-up of this bioaugmented system. Higher than pH 8.0 could restrain the colonization of strain HF-1 in activated sludge. Even though strain HF-1 colonizes in the activated sludge when pH was above 8.0, the removal of nicotine and total organic carbon (TOC) was suppressed due to low activities of bacteria in the activated sludge. Nicotine load did not show inhibition effect on set-up of bioaugmented system, but the ability of TOC removal was restrained when the nicotine load was above 1000 mg/L. This work could offer vital parameters for the set-up of bioaugmented system to treat tobacco wastewater in engineering.
