天然ホルモン除去を含む家畜糞尿・生ごみ混合物の高効率サーマルリサイクル技術の開発

开发了一种有效的牛粪粪便处理工艺，特别是对天然类固醇激素的降解。这一过程的第一步是高温厌氧消化的抽填过程。经自来水四倍稀释后，对厌氧处理出水进行连续进水好氧处理。然后进行间歇式臭氧氧化，以降解好氧处理出水中残留的天然类固醇激素。酵母双杂交试验用于评估激素降解情况。生物处理出水中总VFA、BOD5、CODcr、TOC、TS、VSS和天然类固醇激素的浓度显著降低。对上述浓度的去除效率分别为99.7%、90%、79%、84%、51%、58%和99%。在保持剩余总有机碳和CODcr浓度不变的情况下，臭氧氧化完全去除了天然类固醇激素。在总有机碳负荷率为8g/L、稀释率为0.05d-1的条件下，对含17β-雌二醇的合成废水厌氧消化池中的微生物群落进行了分析。细菌-16S rRNA基因克隆文库分析表明，在该反应器中以变形杆菌和菌丝体为主。

An efficient treatment process for screened cow manure waste, particularly for the degradation of natural steroid hormones, was developed. The first step in this process was a draw-and-fill process for thermophilic anaerobic digestion. After fourfold dilution with tap water, continuous feeding was performed for the aerobic treatment of the effluent from the anaerobic treatment. Batchwise ozone oxidation was then carried out for the degradation of the natural steroid hormones that remained in the effluent from the aerobic treatment. A yeast two-hybrid assay was performed to evaluate hormonal degradation. Significant reductions in the concentrations of total VFA, BOD_5, COD_cr, TOC, TS, VSS, and natural steroid hormones were demonstrated in the effluent from the biological treatments. The removal ratios of such concentrations were 99.7%, 90%, 79%, 84%, 51%, 58%, and 99%, respectively. Although the concentrations of the remaining TOC and COD_cr remained constant, natural steroid hormones were completely removed by ozone oxidation.Microbial community in anaerobic digester for synthetic wastewater treatment containing 17β-estradiol was analyzed under the conditions at 8 g/l of TOC loading rate and at 0.05 d-1 of dilution rate. Bacterial-16S rRNA gene clone library analysis showed that the phylum Proteobacteria and Firmicutes were predominated in the reactor.
