Agricultural biomass is proven ecofriendly and effective adsorbent for the remediation of contaminants from wastewater. Here, rice husk biochar (600 °C) prepared by a one-step pyrolysis method is used for the remediation of different contaminants in real samples. An onsite biofilter unit is fabricated with parallel trenches of different layers of coconut coir and biochar and is used as a biofiltration unit. The efficiency of the designed unit is assessed for the removal of different contaminants in pilot-scale experiments. Results show that removal efficiency varies from metal to metal and ranges from 5.52% to 90.76% using the biofilter unit. Fourier-transform infrared spectroscopy, scanning electron microscopy with energy dispersive X-ray analysis, carbon, hydrogen, nitrogen, and Brunauer–Emmett–Teller analysis before and after the adsorption represent the changes in the morphology and surface functionalization of the biochar. Results indicate that the designed biofilter unit could also be used as a promising agent for the remediation of pharmaceutical and other emerging contaminants from wastewater.

有效修复废水污染物的就地生物滤池装置的设计与开发
农业生物质被证明是生态友好且有效的吸附剂，可用于修复废水中的污染物。在这里，通过一步热解法制备的稻壳生物炭 (600 °C) 用于修复实际样品中的不同污染物。一个现场生物过滤器单元是用不同层的椰子壳和生物炭的平行沟槽制造的，用作生物过滤单元。在中试规模实验中评估设计单元去除不同污染物的效率。结果表明，去除效率因金属而异，使用生物过滤器装置的去除效率在 5.52% 到 90.76% 之间。傅立叶变换红外光谱、带能量色散 X 射线分析的扫描电子显微镜、碳、氢、氮、和吸附前后的 Brunauer-Emmett-Teller 分析代表了生物炭的形态和表面功能化的变化。结果表明，设计的生物过滤器单元也可用作修复废水中的药物和其他新兴污染物的有前途的试剂。
