研究了微量Co,Ni对稻草厌氧消化过程中的CODCr,pH,挥发性脂肪酸(VFA),产气量及产气速率的影响.结果表明:投加了Co,Ni和Co+Ni的实验处理,其产气量分别提高了39.0%,74.5%和115.0%;ψ(甲烷)从44.9%分别提高到50.0%,52.2%和62.5%;挥发性固体(VS)去除率从39.3%分别提高到46.2%,47.6%和53.2%,CODCr去除率从42.4%分别提高到56.9%,57.0%和58.9%.投加微量Co,Ni对稻草的厌氧消化能力具有显著的促进作用.3种投加方式对厌氧消化系统的促进效果存在差异,其中投加Co+Ni混合微量金属是提高稻草厌氧消化效率和产气量的有效方法.
