桐庐县富春江、分水江库区漂浮物主要由水葫芦、生活垃圾、动物尸体三部分构成,结合桐庐县垃圾处理处置设施建设现状及规划,对水葫芦及生活垃圾采用机械打捞-压缩中转-烘干(仅水葫芦)-焚烧工艺,对动物尸体采用人工打捞-冷藏车运输-冷库储存-焚烧工艺。为确保水葫芦焚烧可行性,比较了烟气直接烘干和蒸汽间接烘干两种工艺,推荐采用蒸汽间接烘干。 相似文献

2003年三峡水电站蓄水发电后,漂浮物将严重地影响机组的正常发电、危及机组的安全运行,并且对下游的葛洲坝水电站造成威胁,本文根据三峡水电站漂浮物的组成特点,从我国城市垃圾处理的现状和再生资源利用的现状及环境保护的角度出发,讨论了漂浮物的三种处理方案-卫生填埋,焚烧回收热能,再生利用。根据三峡水电站周边地区垃圾处理现状,漂浮物治理现状以及经济的角度等,对三种方案进行了综合评价,认为再生利用漂浮物更加可行。 相似文献

Wastewater stabilization ponds generate low cost by-products that are useful for agriculture. The utilization of these by-products for soil amendment and as a source of nutrients for plants requires a high level of sanitation and stabilization of the organic matter, to maintain acceptable levels of soil, water and air quality. In this study, two aquaculture wastewater treatment systems; recirculating system and a floating plant bed system were designed to improve the quality of irrigation water in local communities with low income. In both systems the grass species Lolium perenne Lam was used as a plant biofilter while vegetable specie Amaranthus viridis was used to evaluate the performance of the system and the suitability of the phyto-treated water for irrigation. It was found that the harmful material removal rate for recirculating system was 88.9% for TAN (total ammonia nitrogen), 90% for NO2--N, 64.8% for NO3--N while for floating plant bed system 82.7% for TAN, 82% for NO2--N and 60.5% for NO3--N. Comparative analysis of the efficiency of waste element removal between the two systems revealed that both systems performed well, however, plant growth was not robust for floating plant bed system while recirculating system is energy consuming.
Although both systems did not attain sufficient levels of TN (total nitrogen) and TP (total phosphorus) load reduction, the treatment with L. perenne remarkably improved the irrigation water quality. A. viridis plants irrigated with the phyto-treated discharge water had lesser concentrations of heavy metals in their tissues compared to those irrigated with untreated discharge. The control plants irrigated with untreated discharge were also found to be highly lignified with few stems and small leaves. 相似文献
