The ability of biochar beads embedded with freshwater algae ̶ Chlorella pyrenoidosa (Bc-Cp beads) were investigated for their efficiency in the removal of pollutants. Combining these is an innovative concept which can result in improvements in pollutant removal since both, biochar and algae have the ability for adsorbing/absorbing pollutants. Additionally, only limited work on embedding freshwater algae (common algae existing in surface water and having low ecological risks since they are native species) into biochar for the removal of water pollutants has been undertaken to-date. It was found that Bc-Cp beads prepared using 10 mL of algae (9 × 10⁸ cell/mL), 0.3 g of biochar, 40 g/L of sodium alginate, and 20 g/L of CaCl₂ displayed the optimum characteristics including mechanical strength (2.548 N), promotion of algae growth (191.70 % growth rate) and pollutant removal ability with the removal efficiency of ammonia nitrogen, total nitrogen and total phosphorus, total organic carbon, zinc and copper were up to 69.2 %, 43.0 %, 73.8 %, 81.0 %, 74.4 % and 81.0 %, respectively. The algae within the beads were primarily responsible for the removal of nutrients by assimilation, while biochar mainly exerted influence on the removal of organic matter and heavy metals by chemisorption. The study outcomes also confirmed that Bc-Cp beads possess high potential to be used in estuarine environments and saline groundwater.

研究了嵌入淡水藻类water小球藻（Bc-Cp珠）的生物炭珠的去除污染物效率。将这些结合在一起是一个创新的概念，因为生物炭和藻类都具有吸附/吸收污染物的能力，因此可以改善污染物的去除。此外，迄今为止，仅进行了有限的工作，以将淡水藻类（存在于地表水中的普通藻类由于其为原生物种而具有较低的生态风险）嵌入生物炭中以去除水污染物。发现使用10 mL藻类（9×10 ⁸细胞/mL)、0.3 g生物炭，40 g / L海藻酸钠和20 g / L CaCl ₂制备的Bc-Cp珠氨氮，总氮，总磷，总有机碳，锌，铜的去除率均达到了机械强度（2.548 N），促进藻类生长（增长191.70％）和去除污染物的最佳特性。分别为69.2％，43.0％，73.8％，81.0％，74.4％和81.0％。珠粒中的藻类主要负责通过同化作用去除营养，而生物炭主要影响通过化学吸附去除有机物和重金属。研究结果还证实，Bc-Cp珠具有在河口环境和含盐地下水中使用的潜力。
