城市生活垃圾焚烧灰渣的资源化利用   总被引:27,自引:1,他引:26  
以国外城市生活垃圾焚烧灰渣资源化利用现状为基础,讨论了灰渣利用的主要途径:(1)石油沥青路面的替代骨料;(2)水泥或混凝土的替代骨料;(3)填埋场覆盖材料;(4)路堤、路基等的填充材料,已有的工程实践证明,只要控制处理得当,这些灰渣资料化利用可以不对人类健康和环境产生不利的影响,此外,也对灰渣资源化利用在环境标准和工程性质要求方面的规定及其采取的处理方法作了简单的分析。底灰经预处理后资源化利用,而飞灰经稳定化处理后填埋,是今后比较适合我国国情的灰渣管理策略。  相似文献

洞庭湖区溃垸前后血吸虫病流行区螺情变化分析   总被引:3,自引:0,他引:3  
目的:了解洪涝灾害对血吸虫病流行区螺情的影响程度。方法:选择遭受过严重洪涝灾害且溃垸的8个围烷,回顾性调查围垸受灾前后螺情及螺等情况。结果:8个被调查溃垸中,除2个围垸垸内受灾后未发现钉螺外,其他6个垸垸内受灾后钉螺面积均有不同程度的扩大,钉螺总面积是受灾前的10.8倍。其中围堤湖垸受灾前垸内无螺。灾后发现了钉螺。受灾后垸内活螺平均密度,垸外阳性螺平均密度和钉螺阳性率在大部分溃垸比受灾前均有不同程度的降低。结论:洪涝灾害能引起大部分溃垸垸内钉螺不同程度的扩散以及能降低部分溃决提垸垸外的阳性螺平均密度和钉螺阳性率,钉螺是否扩散及其扩散程度受诸如决口处是有钉螺分布,活螺密度,水淹面积,泥沙覆盖面积等因素的影响。  相似文献

Although several researchers have addressed the risk of congenital anomaly in relation to proximity to landfill sites, few have considered the risks of stillbirth or neonatal death for mothers who reside near landfills. The authors studied all 4,325 stillbirths, 3,430 neonatal deaths, and 1,569 lethal congenital anomalies that occurred among 287,993 births to mothers residing in Cumbria, northwest England, during the years 1950 to 1993. Logistic regression models, with data stratified by time period and adjusted for subject-specific demographic factors, were used to investigate the risk for each outcome in regard to proximity at birth to landfill sites within Cumbria. For the years 1970--1993, a small but significantly increased risk of death from "Other congenital anomalies of nervous system" (International Classification of Diseases, 9th rev. [ICD-9], code 742) was found in children of mothers living near domestic waste landfill sites. There was no increased risk of any other lethal adverse pregnancy outcome associated with residence near the landfills studied. The authors' finding of increased risk of death from "Other congenital anomalies of nervous system" closer to landfill sites (e.g., continuous odds ratio = 1.14 [95% confidence interval = 1.03, 1.25] for increasing proximity to landfill sites during 1976--1993) was consistent with findings of other researchers; however, a casual effect could not be inferred from this statistical association, and the possibility that this was a chance finding (in view of multiple significance testing) could not be excluded. Further research incorporating actual pollution data collected around landfill sites and the examination of both lethal and nonlethal congenital anomalies is recommended  相似文献
