聊城市农药包装废弃物回收处理工作的探索与实践 总被引：1，自引：0，他引：1
《农药科学与管理》2021,42(8)
近年来,聊城市大力开展农药包装废弃物回收处理工作。通过市级制定出台政策办法,县级统筹资金建立乡村三级农药包装废弃物回收体系,形成了一套村级回收、乡镇暂存、县级贮存销毁的农药包装废弃物回收处理工作模式。本文通过对聊城市开展的农药包装废弃物回收处理工作进行总结分析,以期为我国农药包装废弃物回收处理工作的推进提供可参考的经验做法。 相似文献

Mixtures of wet vegetable wastes (Brassica, carrot or onion) and dry onion waste were composted at 50 °C for 7 days. The incorporation of the raw or composted vegetable waste mixtures into sandy loam, silt and peat soils reduced the viability of sclerotia of S. cepivorum in glasshouse pot bioassays. The reduction in viability was dependent on waste type, rate of incorporation, duration of exposure and soil type. Onion waste was the most effective waste type in reducing sclerotia viability in all three soils. The Brassica and carrot wastes were as effective as the onion waste in silt soil but less effective in sandy loam and peat soil. A 50% w/w incorporation rate of the wastes gave the largest reduction in viability, with an increase in reduction over time. Composted onion waste reduced sclerotia viability under glasshouse and field conditions although the effect was smaller in the field. Composted onion waste incorporated into soil at 50% w/w reduced the incidence of Allium white rot on onion seedlings in glasshouse pot tests. Incidence and control of the disease differed with soil type. The most consistent control was achieved in peat soil whereas no control was observed in silt soil. Incorporation of the waste 2 months prior to sowing or transplanting reduced seedling emergence in sandy loam soil and growth in all three soil types. The potential for field application of composted vegetable wastes as a sustainable method for control of Allium white rot and waste disposal is discussed. 相似文献

西安市环境库兹涅茨曲线分析 总被引：1，自引：0，他引：1
借助1990-2010年的统计数据,运用Eview软件,对西安市的经济增长与环境3大指标（工业废气、废水、固体废物）之间的关系进行拟合,对其关系是否符合环境库兹涅茨曲线（EKC）倒“U”型模型进行验证,并采用因素分析法,对影响环境质量的因子进行分析。结果表明：① 西安市经济增长与环境3大指标之间的关系都不符合环境库兹涅茨曲线,经济增长与废气排放和废水排放的关系均满足倒“N”型曲线,与固体废物排放的关系基本满足“U”型曲线;② 废气排放与废水排放开始显示下降趋势,而固体废物的排放依然在不断上升,并且没有发现达到最高点的迹象;③西安市的环境质量变化主要是由经济因素引起的。 相似文献

西安市经济发展与环境关系的关联分析 总被引：4，自引：0，他引：4
从要素、产业、经济群体三个层次,分别研究了“三废”排放与经济资源要素的关联、工业结构与能源和“三废”排放要素的关联、经济系统与环境系统的协调状况。文章认为,西安市的三废排放量与人口因素和经济规模因素密切相关,而与能源消费状况相关程度相对较低,其间差异性也较大。工业总产值、轻工业总产值和重工业总产值对污染物排放量的关联度小于对能源消费量的关联度。经济环境系统总体处于不协调状态,只有经济结构功能处于比较协调状态,经济规模、经济效益、环境质量、环境治理均处于不协调状态,环境污染功能处于极不协调状态,系统无一功能处于高度协调状态。文章从经济和环境政策法规、规划布局、治理技术、结构调整等方面,对大气、水体、固体废弃物的治理提出具体且切实可行的措施。 相似文献

榆林市工业”三废”污染及其治理对策 总被引：4，自引：0，他引：4
以榆林市 1 989- 2 0 0 2年的统计资料为依据 ,分析得出近年来该市工业废水排放量减少 ,废水排放达标率较高 ;工业废气排放量呈上升趋势 ,工业废气处理率呈下降趋势 ;工业固体废物产生量增加 ,而综合利用率很低。工业废气和固体废物的污染是榆林市的主要环境问题 ,也是妨碍该市社会经济发展的突出问题。产生工业污染的主要原因是 :生产工业水平低 ,公众环保意识差 ,环保设施建设投入不够 ,环境管理执法力度不强。榆林市工业”三废”污染处理对策主要有 :加强”三废”处理设施建设 ,加大废气处理力度 ,利用清洁能源 ,加强废水处理和回收再利用 ,提高工业固体废物的综合利用率 ,加强环境管理 ,实施”污染者付费”的经济政策和管理方法 ,加强宣传教育 ,提高公众环保意识。 相似文献

咸阳市工业三废对环境的污染及其防治 总被引：3，自引：0，他引：3
根据咸阳市 1 981 - 2 0 0 1年的统计资料可知 ,近 2 0年来咸阳工业三废污染问题非常严重。虽然工业废水排放量减少 ,但废水达标率却上下波动 ,处理率不高 ;工业固体排放量快速上升 ,且处理率很低 ,有大量固体废物未加处理、利用 ;工业废气排放量直线上升 ,工业粉尘去除率非常低。这些都制约着咸阳地区的进一步发展。产生工业污染的原因很多 ,主要是咸阳工业布局不合理及生产工艺低下 ,其次是人们环保意识低下和政府环境执法工作力度不大。治理咸阳地区工业三废污染的措施主要有 :减少污染源的措施 ;污染者负担治理费的措施 ;大力加强咸阳地区环境治理设施 ;提高固体废物处理和综合利用率 ;严格推行除尘和烟气脱硫技术。 相似文献

Survival of infectious inoculum of the clubroot pathogen Plasmodiophora brassicae was assessed following bench-scale flask composting experiments and large-scale composting procedures. Clubroot-affected material was provided by artificial inoculation of Chinese cabbage or naturally infected Brussels sprout and cabbage roots. Both sets of diseased material were used in flask experiments, and the latter in large-scale windrow and aerated tunnel experiments. Municipal green wastes, onion waste and spent mushroom compost were evaluated in flask experiments with varying temperature, aeration and moisture conditions. Green wastes were used in larger-scale composts. Within the limits of a Chinese cabbage seedling bioassay, both temperature and moisture content were critical for eradication of P. brassicae spores extracted from composted clubroot-affected residues. Incubation in compost at 50°C for 7 days or 1 day at 60°C with high moisture levels (= −5 kPa matric potential or 60% w/w moisture content) eradicated inoculum from artificially inoculated Chinese cabbage roots. In large-scale windrows and aerated tunnels, the pathogen was eradicated from naturally infected brassica wastes after 6–7 days at 54–73°C. 相似文献

Approximately 400000 litres of cattle dip wastes containing approximately 1500 mg litre−1 of the organophosphate insecticide coumaphos are generated yearly along the Mexican border from a USDA program designed to control disease-carrying cattle ticks. Use of unlined evaporation pits for the disposal of these wastes has resulted in highly contaminated soils underlying these sites. Previous work has shown that microbial consortia present in selected dip wastes can be induced to mineralize coumaphos. Our results demonstrate that similar microbial consortia are present in coumaphos-contaminated soils from eight waste sites and that these organisms are capable of mineralizing cou-maphos in these soils using soil slurries to less than 1 mg litre−1 in 7–10 days at 28°C. In addition, our results show that these consortia are able to colonize pea gravel in trickling gravel filters and can be used in these filters to metabolize coumaphos from dip wastes to less than 0·1 mg litre−1 in 7–10 days at 28°C. These simple systems offer potential low cost means to detoxify coumaphos-containing wastes and to bioremediate soils contaminated with this organophosphate compound. 相似文献
