This study focuses on the evaluation of the performance of Chlorella sp. in removing nutrient in aquaculture wastewater and its correlation with the kinetic growth of Chlorella sp. The treatment was applied with various Chlorella sp. inoculation dosage ranging from 0% to 60% (v/v) of wastewater. The optimum inoculation dosage was recorded at 30% (v/v) with effluent concentration of ammonia and orthophosphate recording at 0.012mgL(-1) and 0.647mgL(-1), respectively on Day 11. The optimum dosage for bio-flocculation process was obtained at 30mgL(-1) of Aspergillus niger with a harvesting efficiency of 97%. This type of development of phytoremediation with continuous bio-harvesting could promote the use of sustainable green technology for effective wastewater treatment.
本研究专注于评估小球藻在去除水产养殖废水中营养物质方面的性能，及其与小球藻动力学生长的相关性。该处理应用了不同的小球藻接种剂量，范围从废水的 0%到 60%（v/v）。在第 11 天，当接种剂量为 30%（v/v）时，氨和正磷酸盐的出水浓度分别记录为 0.012mg/L 和 0.647mg/L，此时的接种剂量为最佳。黑曲霉的最佳生物絮凝过程剂量为 30mg/L，收获效率为 97%。这种具有连续生物收获的植物修复的发展可以促进可持续绿色技术的使用，以实现有效的废水处理。
