Response of antioxidase in viscera of Pagrosuma major larvae to water soluble fraction of hydrocarbons in No.0 diesel oil

Pagrosomus major larvae were to the water-soluble fraction of hydrocarbon in No.0 diesel oil(corresponding to No.2 fuel oil) at concentration of 0,0.17,1.22 and 8.82mg/L for up to 15 days.Larvae were sampled on days 9 and 15 of the experiment.Supernatants of viscera tissue extractions were assayed for biochemical response in terms of oxidative stress-superoxide dismutase(SOD),activity of selenium-dependant glutathione peroxidase(Se-GPx) and catalase(Ca),and the concentration of reduced glutathione(CSH).On day 9 of exposure ,statistically significant dose-related increases in Se-GPx and SOD activity,and GSH concentration were observed in all cases except for Se-GPx activity under the highest dosage of hydrocarbon.However,on day 15 of exposure, a similar dose-related in all cases except for Se-GPx activity under the highest dosage of hydrocarbon.However,on day 15 of exposure, a similar dose-related response was only observed for Se-GPx activity.GSH concentration decreased and SOD activity showed no statistical difference as compared to controls.However, a significant decrease in compared to day 9 Se-GPx activity and GSH concentration, in contrast to increase SOD activity at day 15 as indicates an accelerated accumulation of H2O2 and potential oxidative damage under long term exposure of larvae to hydrocarbons.No statistical changes were observed in Ca activity throughout the experiment, possibly owing to the high efficiency of Se-GPx.A recovery experiment was performed on indicating that the response of antioxidants measured tending to returm to return to their control levels.These results prove the function of the antioxidant defense system of the larvae to the water-soluble fraction of hydrocarbons in No.0 diesel oil.     

催化裂化含酚废水的预处理研究

无锡市生活垃圾控制对策

介绍了无锡市生活垃圾的现状，通过类比调查，提出垃圾分类收集、焚烧发电、剩余物卫生填埋的处理方法，是实现无锡市垃圾无害化、减量化、资源化的有效途径。     

中国垃圾焚烧发电工程的发展历程与趋势

垃圾焚烧技术在我国得到了快速应用。2018年我国垃圾焚烧量达到1.02亿t,占总无害化量的45%,将很快形成"焚烧为主,填埋托底"的垃圾终端处理格局,也还将继续由"能量回收型"向"资源回收型"发展。垃圾焚烧工程不仅在规模上得到了增长,同时在焚烧技术、烟气净化系统和市场竞争形势上也发生了深刻变化。我国垃圾焚烧行业依然存在较多技术痛点和发展瓶颈,可持续发展面临新的挑战和机遇。未来,建议垃圾焚烧企业和行业应探索中小城市（<50万人口）垃圾焚烧推广和盈利模式,响应矿化垃圾开采及焚烧处置需求,补齐垃圾焚烧飞灰无害化处置和资源化利用短板;在"提高发电效率,降低厂用电率"等方面提高技术水平和管理能力,加强"邻利"理念引领;积极布局国际市场,重视与高校科研院所的互动,以推动技术创新和技术转移。     

核桃果皮基磁性固体酸催化剂的制备及其催化性能研究

采用自底向上策略,利用农业废弃物核桃青果皮制备了磁性碳质固体酸催化剂,并对其进行了BET、XRD、SEM、IR和TGA等表征分析.结果表明,合成的磁性固体酸催化剂结构蓬松,比表面积大,具有良好的热稳定性.催化剂MPCs-0.2-SO₃H在生物柴油的合成中具有良好的催化活性.当醇油比为30,催化剂加入量为油酸质量的7%,80℃反应8 h酯化率达到74.2%,比商用Amberlyst-15催化剂的酯化率高近20%,最高含水量可达油酸质量的4%,重复使用3次后仍具有较高的酯化率,不仅实现了废弃物的资源化,而且得到的催化剂磁性易分离,在生物柴油的合成中具有巨大的应用潜能.     

我国城乡生活垃圾处理行业创新路径研究——基于技术与政策的双重视角

当前,我国城乡生活垃圾产生量及清运量逐年上升,传统填埋及堆肥方式无法持续,垃圾处理方式向焚烧发电转变。近年来,凭借垃圾处理与可再生能源利用的双重身份,垃圾焚烧发电受到多重经济优惠政策的支持,但也存在会产生二噁英、含重金属飞灰等二次污染,行业经营的排他性、垄断性等问题。本文认为,在追求垃圾"减量化"的同时更应注重垃圾处理的"无害化";在"源头分类—垃圾焚烧"的基础上,改变垃圾处理补贴政策单一化的现状,加大对垃圾绝氧热解等新技术的政策扶持力度,从根本上实现垃圾减量化、无害化、资源化的处理目标。
