中文摘要：

探索了垃圾焚烧飞灰在处理涂装磷化废水方面的资源化利用途径,通过红外光谱（FT-IR）分析、比表面积（BET）与孔径（BJH）测试,探讨了处理机制。结果表明,飞灰去除涂装废水中高含量的磷、镍效果均十分显著,常温30 min磷与镍的去除率均达到99%以上,受温度、振荡转速影响小,涂装废水进水不需调节pH。出水中各指标均达到GB8978-1996一级排放标准,且未产生新的重金属污染。飞灰在处理过程中未出现多孔性结构,吸附作用不是除磷的主要机制;化学沉淀是除磷、除镍的主要机制,原水中的以镍为主的重金属离子在为除磷过程提供阳离子同时也得到去除。飞灰中可溶性重金属与磷酸盐发生沉淀反应,在处理废水的同时稳定化了重金属,处理后飞灰浸出液中Zn、Pb的含量分别降低了86.1%、95.2%。

英文摘要：

Resource utilization method of fly ash on the treatment of coating phosphatizing wastewater was explored through infrared spectroscopy （FT-IR） analysis, specific surface area （BET） and pore size （BJH） test, and the treatment mechanism also was discussed. The results showed that： the removal effect of fly ash to high content phosphorus and nickel in coating wastewater are very significant. And nickel phosphorus removal rate reached more than 99% at room temperature for 30 min, with being affected indistinctively by vibration speed and temperature, without being adjusted the pH of influent coating wastewater. The effluent water had reached a level of wastewater discharge standard, and did not produce heavy metal pollution. Fly ash did not appear porous structure in the treatment process, and the main mechanism of adsorption was not the absorption; chemical precipitation was the main mechanism of phosphorus and nickel removal. In addition, nickel heavy metal ions which provided the cationic for phosphorus removal process in raw water also were removed. Soluble heavy metals and phosphate produced precipitation reaction in fly ash, at the same time heavy metals was stabilized in wastewater treatment process. The heavy metal content in leaching solution of fly ash, Zn, Pb were decreased by 86.1%, 95.2% after treatment.
