与生活垃圾协同焚烧是污泥处置中最有前景的处置方式,但其对焚烧烟气污染物排放的影响尚未明确。利用生活垃圾焚烧炉开展生活垃圾协同处置市政污泥的试验,研究掺烧5%、10%和15%的市政污泥时焚烧烟气中酸性气体、烟尘、重金属和二噁英等的排放特征。结果表明:与单独焚烧生活垃圾的对照组相比,在各掺烧比例下,烟气中SO_2、HCl、NO_x及烟尘有一定程度的增加,但均未超过GB18485—2014《生活垃圾焚烧污染控制标准》限值;Cu、Hg排放质量浓度明显下降,Cr、Cd波动下降,Pb在高掺烧比时仍远低于限值,Ni增长幅度小于15%;二噁英总量升高,但仍符合标准限值。因此,在掺烧比例不超过15%的情况下,焚烧烟气中污染物排放仍在安全可控范围。 相似文献

Long-lasting expansion of haze pollution in China has already presented a stern challenge to regional joint prevention and control. There is an urgent need to enlarge and reconstruct the coverage of joint prevention and control of air pollution in key area. Air quality models can identify and quantify the regional contribution of haze pollution and its key components with the help of numerical simulation, but it is difficult to be applied to larger spatial scale due to the complexity of model parameters. The time series analysis can recognize the existence of spatial interaction of haze pollution between cities, but it has not yet been used to further identify the spatial sources of haze pollution in large scale. Using econometric framework of time series analysis, this paper developed a new approach to perform spatial source apportionment. We applied this approach to calculate the contribution from spatial sources of haze pollution in China, using the monitoring data of particulate matter (PM2.5) across 161 Chinese cities. This approach overcame the limitation of numerical simulation that the model complexity increases at excess with the expansion of sample range, and could effectively deal with severe large-scale haze episodes. 相似文献

The aim of this study was to assess the effect of substrate type and incubation depth on periphyton that had developed on artificial substrates. Uniform rectangular tiles made out of artificial substrates: glass, ceramic, willow tree and yew tree, were fixed on a floating buoy and deployed at three different depths in a photic zone of the Sava Lake (Belgrade, Serbia). Non-taxonomic attributes in the developed biofilm were estimated week-by-week from the start of the experiment in July, until its end in September 2014. Through assessment of substrate type and depth of incubation effect we concluded that these parameters for the fact influence periphyton development and composition. Glass was preferred by autotrophic component over ceramic and wooden substrates. In general, substrate type effect was diminished by increasing incubation depth. When non-taxonomic parameters are to be used in biomonitoring studies, our results suggest that glass substrate and shallow layer of water column (up to 50 cm) for incubation should be preferred. 相似文献
