The potential application of Chlorella vulgaris UMACC 001 for bioremediation of textile wastewater (TW) was investigated using four batches of cultures in high rate algae ponds (HRAP) containing textile dye (Supranol Red 3BW) or TW. The biomass attained ranged from 0.17 to 2.26 mg chlorophyll a/L while colour removal ranged from 41.8% to 50.0%. There was also reduction of NH(4)-N (44.4-45.1%), PO(4)-P (33.1-33.3%) and COD (38.3-62.3%) in the TW. Supplementation of the TW with nutrients of Bold's Basal Medium (BBM) increased biomass production but did not improve colour removal or reduction of pollutants. The mechanism of colour removal by C. vulgaris is biosorption, in accordance with both the Langmuir and Freundlich models. The HRAP using C. vulgaris offers a good system for the polishing of TW before final discharge.
采用含有纺织染料（Supranol Red 3BW）或纺织废水（TW）的高效藻类塘（HRAP）中的四批培养物，研究了小球藻 UMACC 001 用于纺织废水（TW）生物修复的潜力。生物量的范围为 0.17 至 2.26mg 叶绿素 a/L，而颜色去除率的范围为 41.8%至 50.0%。在 TW 中，NH(4)-N（44.4-45.1%）、PO(4)-P（33.1-33.3%）和 COD（38.3-62.3%）也有所减少。用 Bold's Basal Medium（BBM）的营养物质补充 TW 会增加生物量的产生，但不会提高颜色去除率或减少污染物。小球藻去除颜色的机制是生物吸附，符合朗缪尔和弗罗因德利希模型。使用小球藻的 HRAP 为 TW 在最终排放前的抛光提供了一个很好的系统。
