Anaerobic digestion of common rural wastes (human feces (HF), food waste (FW) and lawn grass (LG)) were studied considering the specific methane yield, process parameters and microbial characteristics (mainly microbial community and pathogenic bacteria). The results showed that co-digestion of multiple substrates obtained high digestion performance when the total solid (TS) was 4%. The optimal co-digestion ratio of HF, FW, and LG was 33–56%, 21–38% and 20–40%, respectively. The digestion system containing HF underwent ammonia inhibition, which leads to the succession of the methanogenesis pathway from the acetoclastic pathway to the hydrogenotrophic pathway. Simultaneously, the dominant methanogenic archaea changed from Methanosaeta to Methanobacterium and Methanosarcina. Co-digestion reduced Salmonella's absolute concentration. The recovered energy and nitrogen could meet 52–109 % energy demand of rural community and all nitrogen demand in lawn fertilization, respectively. The main rural organic wastes could be recycled by anaerobic digestion, considering the flexibility of substrate ratio.

考虑到特定的甲烷产量、工艺参数和微生物特征（主要是微生物群落和病原菌），研究了常见农村废物（人类粪便（HF）、食物垃圾（FW）和草坪草（LG））的厌氧消化。结果表明，当总固体(TS)为4%时，多种底物共消化获得了较高的消化性能。HF、FW 和 LG 的最佳共消化率分别为 33-56%、21-38% 和 20-40%。含有 HF 的消化系统经历了氨抑制，导致产甲烷途径从乙酰碎屑途径连续到氢营养途径。同时，占优势的产甲烷古菌由Methanosaeta转变为Methanobacterium和Methanosarcina. 共同消化降低了沙门氏菌的绝对浓度。回收的能量和氮可以分别满足农村社区52-109%的能量需求和草坪施肥的所有氮需求。考虑到底物比例的灵活性，主要农村有机废物可以通过厌氧消化进行回收。
