The core-shell structured polypyrrole/polyaniline (PPy@PANI) were synthesized by in-situ polymerization method and were used as the conductive medium to enhance methane production from the anaerobic wastewater treatment. It was found that the PPy@PANI has a good performance on methane production from the anaerobic wastewater treatment, and it composites can improve the methane production rate and yield by 70.2% and 28.3% in the initial 4 h compared with the control group. A high methane production rate was achieved when the dosage of PPy@PANI was 0.6 g/L, which suggested that 0.6 g/L was the optimal dosage. Finally, the mechanisms involved in the improved methane production rate by the PPy@PANI were disclosed. The PPy@PANI can enrich the functional microorganisms to enhance both the degradation of organics and the electron transfer, which contributed to the improved methane production rate from the anaerobic wastewater treatment.

核壳结构的聚吡咯/聚苯胺（PPy@PANI）是通过原位聚合法合成的，并用作导电介质以提高厌氧废水处理的甲烷产量。发现PPy@PANI对厌氧废水处理产生的甲烷具有良好的性能，与对照组相比，它的复合物在最初的4小时内可以提高70.2%和28.3%的甲烷产率和产率。当 PPy@PANI 的用量为 0.6 g/L 时，可实现较高的甲烷产率，这表明 0.6 g/L 是最佳用量。最后，公开了 PPy@PANI 提高甲烷产率的机制。PPy@PANI 可以富集功能微生物，以增强有机物的降解和电子转移，
