  • 摘要: 实验研究了不同pH、温度、Mg2+投量和沉降时间下，镁盐、炉渣、镁盐+炉渣3种处理对模拟和实际印染废水的脱色效果。结果表明，在pH为11~11.5、沉降30 min、30℃及Mg2+投加量为500~600 mg/L的最优脱色条件下，3种处理对艳红FXC模拟废水的最大脱色率分别为98.41%、98.43%和99.37%，对实际印染废水的最大脱色率分别为90.18%、89.63%和93.33%，其中，镁盐+炉渣脱色效果最好，这可能与炉渣吸附和起到协同增强Mg（OH）2沉淀效果的作用有关。对水样的液相色谱初步检测分析表明，实际废水脱色处理前后染色基团峰高和种类发生了变化。该研究对盐田富镁卤水和炉渣等废物的资源化开发有重要参考价值。
    Abstract: Under the conditions of different pH, temperatures, Mg2+ dosages and sedimentation times, the decoloration of simulated and actual dyeing wastewater in three treating modes(Mg2+ salt, slag and (Mg2++slag)) were studied. The results showed that under the optimal conditions of pH(11~11.5), sedimentation time (30 min), temperature(30℃) and Mg2+ dosage (500~600 mg/L), the maximum decoloration rate in the three treating modes reached 98.41%, 98.43% and 99.37% for brilliant-red FXC simulated dyeing wastewater, and 90.18%, 89.63%, 93.33% for actual dyeing wastewater, respectively. Among the three treating modes, (Mg2++slag) was the most effective one in decoloration, which may be attributed to the slag's adsorption and synergistic decoloration effect by accelerating Mg (OH)2 precipitation. Analysis on HPLC characteristic of pre-and post-treated actual dyeing wastewater indicated that the peak height and varieties of dyeing groups in wastewater underwent some changes. The research is of important value to the exploitation of waste resources such as saltern Mg2+-riched brine and some kinds of slags.
