摘要:

石油树脂废水污泥属于危险废物,通过污泥主要成分分析,提出污泥资源化途径,研究其对磷的吸附条件及效果。结果表明,石油树脂废水污泥含有较多的苯、萘、茚、薁、烯烃、烷烃等石油类污染物,污泥经600 ℃煅烧后,减量化程度达到82.5%,得到以γ?Al2O3为主的吸附材料;煅烧污泥对磷的最佳吸附条件:吸附时间为90 min,振荡强度为180 r/min,pH为4,初始磷质量浓度为12.5 mg/L,煅烧污泥质量为2.0 g。在最佳吸附条件下,吸附率为93.8%,污泥再生后对磷吸附率为87.0%。因此,石油树脂废水污泥经过煅烧处理后,可实现危险废物的减量化和资源化。

Abstract:

Petroleum resin wastewater sludge is classified as hazardous waste. The method of sludge recycling was introduced through the analysis of the main components of sludge, and the adsorption conditions and effects of phosphorus were studied. The results show that the main components of petroleum resin wastewater sludge are petroleum pollutants such as benzene, naphthalene, indene, azulene, olefins, alkanes and so on . After calcined at 600 ℃, the weight reduction of sludge was 82.5%, and an adsorption material based on γ?Al2O3 was obtained. The optimal adsorption conditions of calcined sludge for phosphorus: Adsorption time is 90 min, oscillation intensity is 180 r/min, pH=4, initial phosphorus concentration is 12.5 mg/L and dosage of sludge is 2.0 g. The optimal adsorption removal rate of phosphorus is 93.8%, and the adsorption removal rate after circulation is 87.0%. Therefore, after the calcination treatment of petroleum resin wastewater sludge, the reduction and recycling of hazardous waste can be successfully achieved.
