养猪废水处理厂污染物和新出现污染物的消除

Elimination of Pollutants and Emerging Contaminants from Hog Wastewater Treatment Plants

旨在探讨养猪废水中污染物的有效去除方法。由于养猪废水中含有大量难以降解的污染物,现有处理厂的处理效果并不理想。因此提出了一种多级废水处理系统,但该系统在去除氮和磷方面仍有局限。为了弥补这一不足,系统中集成采用氧化沟和多功能材料过滤技术对硝化后的废水进行处理,从而实现了氮和磷的有效去除。结果显示,大部分抗生素化合物的去除率超过90%,但仍有少数化合物在最终废水中未能完全去除,还发现了天气条件对抗生素去除效率也产生了一定影响。综上所述,多级废水处理系统在养猪废水处理方面取得了一定成效,但仍需进一步优化和完善。未来研究将致力于开发更为高效、环保的废水处理技术,以最大程度降低养猪废水对环境和人类健康的潜在风险。

This study aims to explore effective methods for removing pollutants from swine wastewater.Due to the presence of a large amount of refractory pollutants in swine wastewater,the treatment effect of existing treatment plants is not satisfactory.To address this issue,a multi-stage wastewater treatment system is proposed in this study.However,this system still has limitations in removing nitrogen and phosphorus.To overcome this,the system incorporates the use of oxidation ditches and multi-functional material filtration techniques to treat nitrified wastewater,thereby achieving effective removal of nitrogen and phosphorus.The results showed that the removal rate of most antibiotic compounds exceeded 90%,but a few compounds remained in the final wastewater and were not completely removed.Weather conditions were also found to have an impact on the removal efficiency of antibiotics.Specifically,the removal effect in autumn was generally better than that in spring,but the overall trend of antibiotic removal efficiency under different weather conditions remained consistent.In conclusion,the multi-stage wastewater treatment system proposed in this study has achieved certain success in the treatment of swine wastewater,but further optimization and improvement are still needed.Future research will focus on developing more efficient and environmentally friendly wastewater treatment technologies to minimize the potential risks of swine wastewater to the environment and human health.
