桐庐县富春江、分水江库区漂浮物打捞处置方案

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。     

三峡漂浮物处理方案探讨

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。     

Evaluation of a cost e ective technique for treating aquaculture water discharge using Lolium perenne Lam as a biofilter

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.     

“新三国”剧组污染30万人水源

近日有媒体披露，新版《三国演义》电视剧剧组在浙江永康杨溪水库拍外景，留下大量生活垃圾和油污，可能会影响到永康当地近30万人的饮水水源。剧组拍摄期间，杨溪水库周围除了堆积如山的塑料饭盒、酒瓶甚至粪便等生活垃圾外，由于拍摄交战的夜戏，现场还弥漫着浓重的柴油味，水中也有小部分黑色漂浮物。     

一种新型的油水分离设备

一种将油、水分离和浮油的收集排放过程同时进行的新型油水分离设备在日益高涨的环境保护浪潮中应运而生(见图1).这种新型的油水分离设备,它的主体部分是一个漂浮在水平面以下的箱式结构,一般设置在污水深度净化之前的畅开式水流通道上,在污水流经时,它能以极高的效率除去漂浮在污水表面的油花与其它漂浮物.其工作原理简述如下:
