EFFECT OF NZVI ON ANAEROBIC DIGESTION SYSTEM WITH LOW ORGANIC SLUDGE AND ITS MICROBIAL COMMUNITY DIVERSITY

  • 摘要: 采用投加不同剂量纳米零价铁(NZVI)(0,0.1,0.3,0.5 g/g VS)的低有机质污泥进行半连续中温厌氧消化试验,研究了反应器在不同NZVI投加量下的产甲烷特性及微生物群落变化。研究表明:NZVI的投加前期对产甲烷具有促进作用,随着反应器中NZVI累积逐渐对产甲烷产生抑制,且投加量越高抑制效果产生越早,抑制作用也越强。投加NZVI反应器未造成酸化或氨抑制,厌氧消化系统稳定性较好,系统上清液中磷酸盐去除率最高达到97.78%。NZVI的投加可以促进Firmicutes、Proteobacteria等水解产酸菌和Methanosarcina等多数氢营养型产甲烷菌的生长,而对严格的乙酸型产甲烷菌Methanosaeta生长有一定抑制作用。
