Livestock and poultry waste liquid contains a lot of nitrogen, phosphorus, microorganisms, direct discharge causes great harm to the environment. Chicken manure was selected as research object, nanoparticle nano-Fe2O3, nano-C60, antibiotics enrofloxacin, sulfamethoxazole, oxytetracycin were additives carry out medium-temperature sequential batch anaerobic digestion experiment. The experiment lasted for 55 days. results showed that (1) gas production reached its peak in first 1–2 days single stress experiment, cumulative 10 follows: R5 > R4 R3 R2 CK R1; (2) concentrations total volatile fatty acids (TVFAs) groups increased rapidly from day 1 10, TVFAs nano-Fe2O3 nano-C60 higher than those other four groups. pH system decreased, soluble chemical oxygen demand (SCOD) consistent with trend TVFAs, while group lower; (3) changes horizontal structure bacterial community Firmicutes Bacteroidetes dominant bacteria each on day. On 5, relative abundance actinomycetes significantly. This contributes study effects adding nanoparticles substrates characteristics, provides data support, characterizes microbial situation during digestion. paper can help realize carbon emission reduction agriculture rural areas. Based above background, self-designed testing potential methane used this using chicken manure. pollutant stresses hygromycin, different pollutants under independent performance investigated. parameters diversity process analyzed, elucidated. provide support stable operation biogas projects, which is significance promoting sustainable development ecological agriculture.

Microwave-assisted catalytic oxidation (MACO) is a novel wastewater treatment technology for the efficient degradation of organic wastewater. However, single carbon material or SiC has limited absorption electromagnetic waves, and efficiency using it as microwave-assisted catalyst not satisfactory. To improve performance matrix composites, new magnetic composite Ni@SiC/CNT/CNF microwave constructed. By controlling introduction nickel, different numbers nanotubes are grown on surface nanofibers, C double-shell structures were formed top nanotubes, which catalyzed generation active groups by thermal effect generated plasma discharge under action field, thus realizing highly dyes. The results show that with lowest reflection loss RLmin = −9.26 dB exhibit excellent capabilities 99.9% methylene blue within 90 s 450 W irradiation.
