Abstract

Textile industries are the second largest water-consuming industries, next to agriculture. This research is aimed at investigating the utilization of fly ash as a low-cost adsorbent to treat hot wash liquor by employing one factor at a time. Contact time, effluent dosage, pH, mass of adsorbent, temperature, particle size, and agitation speed have been varied to find the optimum conditions for dye removal from hot wash liquor by fly ash. The results from the sorption process show that the maximum dye removal of 56.07% has been obtained at a time of 5 min, an effluent to water ratio of 9:1, pH of 11, an adsorbent dosage of 0.55 g/mL, a temperature of 27 °C, a fly ash particle size of 128 m and an agitation speed of 100 rpm. The analysis of the results was performed through adsorption capacity and percentage colour removal. Hence, the results suggested that fly ash could be used as an effective adsorbent for treating dyehouse effluents.
粉煤灰处理热洗液
纺织业是仅次于农业的第二大耗水行业。本研究旨在探讨利用粉煤灰作为低成本吸附剂,单因素处理热洗液。通过对接触时间、出水投加量、pH值、吸附剂质量、温度、粒径、搅拌速度等因素的研究,找到了粉煤灰对热洗液脱色的最佳条件。结果表明,在出水比为9:1、pH为11、吸附剂用量为0.55 g/mL、温度为27℃、粉煤灰粒径为128 m、搅拌速度为100 rpm的条件下,吸附时间为5 min,去除率为56.07%。通过吸附量和去色率对结果进行分析。综上所述,粉煤灰可作为一种有效的吸附剂处理染料废水。
