At present, sensitive material factories and various cinefilm processing factories can only treat silver-containing waste water of high concentration, and have difficulties in dealing with the waste water of silver concentration lower than 2-3 mg/1. Therefore the loss of silver is relatively large. This not only leads to a great economic loss, but also brings about seri-

Water hyacinth, E. crassipes, an invasive water weed thrives in fresh water bodies causing serious environmental problems. In Kenya the weed has invaded Lake Victoria and poses great socioeconomic and environmental challenges. Currently the weed is harvested from the Lake and left in the open to rot and decay leading to loss of aesthetics, land and air pollution. There is therefore need for development of value addition and economic exploitation strategies. The aim of the study is to assess the potential for utilization of the weed as a renewable energy resource for biogas production. Samples were collected from Lake Victoria, pulped and blend with cow dung at a ratio of 3:1 as inoculum. The resultant mixture was mixed with water at a ratio of 1:1 and fed into a 6 m3 tubular digester. The digester was recharged with 20 kg after every three days. The temperature, pH variations, gas compositions, upgrading and gas yields were studied. The temperature ranged between 22.8°C - 36.6°C and pH 7.4 - 8.5. Biogas was found to contain 49% - 53% methane (CH4 ), 30% - 33% carbon dioxide (CO2 ), 5% - 6% nitrogen (N2 ) and traces of hydrogen sulphide (H2S). The biogas was upgraded using solid adsorbents and wet scrubbers increasing the methane content by up to 70% - 76%. The upgraded gas was used to power internal combustion engines coupled with an electricity generator and direct heat applications. The study concludes that E. crassipes is a potential feedstock for biogas production especially in areas where it is abundant.

入侵种凤眼莲(Eichhorniacrassipes)在中国的泛滥不仅与其强大的适应力和繁殖能力有关,还与水体的富营养化有很大的关系。作者通过盆栽实验比较了三个营养水平的模拟富营养条件下凤眼莲的生长特征和对当地种黄花水龙(***)和黑藻(Hydrillaverticillata)两个不同生长型的影响。结果表明:富营养条件增强了凤眼莲的生长繁殖能力,使其平均每母株克隆分株数、平均株高以及总生物量极大的增加。凤眼莲的生长优势导致了其竞争优势,对黄花水龙和黑藻都发生了明显的竞争效应。迅速繁殖的凤眼莲覆盖大量水面,通过排挤作用抑制了黄花水龙的生长(低营养水平除外);黑藻因光照缺乏,导致正常光合作用受阻,生物量急剧下降。凤眼莲对黑藻的竞争效应较黄花水龙更强。富营养化的水体为凤眼莲的成功入侵提供了优越条件,因此解决当前水体的富营养化状况能有效控制凤眼莲入侵,同时也有利于本地生物多样性的保护。
