垃圾焚烧飞灰磷酸洗涤对重金属的固定效应研究 总被引:2,自引:0,他引:2
重金属的固定是垃圾焚烧飞灰资源化技术的核心问题.通过系统试验,研究了垃圾焚烧飞灰磷酸洗涤对重金属溶出、后续烧结过程中重金属挥发,以及重金属化学形态变迁的影响.试验结果表明,磷酸洗涤在有效洗脱飞灰中氯盐的情况下,能够显著减少洗涤过程中重金属的溶出,抑制烧结过程中重金属的挥发,从而避免了飞灰处理过程的二次污染;同时,磷酸洗涤使飞灰中的重金属在烧结前后均向更为稳定的化学形态转化,烧结产物中重金属主要以残留态存在,从而提高了烧结产物资源化利用的长期环境安全性. 相似文献

This study is to examine the contribution of socioeconomic status (SES) to the risk of nonfatal pedestrian injury among children. The sample was obtained from two urban cities of China using multi-staged randomized sampling. Information was collected by respondents’ reporting using self-administrative way in the classroom under the guidance of interviewers. A logistic regression analysis was applied to examine the associations between SES and nonfatal children pedestrian injury. The results showed that boys and children aged 10 had significantly increased odds of suffering nonfatal pedestrian injury. Migrant children were at higher risk of being injured. Students whose mothers’ educational levels were either less than secondary school or postgraduate were more likely to sustain injury. Children who were from wealthier families or poorer families easily suffered from injury compared to children from middle families. Children living with grandparents, or siblings, or a single father, or a single mother were all at increased risk of injury. The possible causes or pathways of these SESs’ impacts on pedestrian injury were explored in discussion. This study suggests that SESs are important determinants of nonfatal pedestrian injury among children in China. 相似文献
