规模化肉鸭养殖场污水用于农业灌溉的可行性分析

随着农村规模化肉鸭养殖的蓬勃发展,养殖业废水回用于农业灌溉是否可行,是个值得探讨的问题。本文作者以近年进行的规模化肉鸭养殖环境评价案例为模型,对该行业废水的产生、处理、排放情况进行疏理,并对不同农作物(水稻、棉花)在不同的时期的需水量及灌溉水质进行分析,论证规模化肉鸭养殖场污水用于农业灌溉的可行性。

广西潮上带对虾高产轮养的虾场设计

在防城港市企沙镇建设潮上带虾场，虾场面积80hm^2，虾场由虾池，进水系统，排水系统，增氧系统和其它配套设施组成。其中，虾池分为圆形池和方形圆角池，每口圆形池按0.667hm^2设计，池底半径44.58m，池上面半径48.26m；每口方形圆角池按0.833hm^2设计。池底每条边长89.16m，池上面每条边长96.52m，池中心设计排水系统，利于排污，还能增大排水流量，显著缩短排水时间，工作井按四口虾池建一个，遇到旁边不足四口虾池，则按三口，两口或一口虾池建一个的方案设计与四口虾池联通的工作井为六形（面积23.4m^3)，与两口虾池联通的工作井为长方形（16.0m^2)，这种设计既节省投资，又利于排水，排污和收虾，虾场已经过几年大规模对虾高产轮养试验示范。试验结果表明，各系统设计合理，使用正常，能满足集约化对虾高产养殖的技术要求。

Perspectives of China’s Wind Energy Development

Wind energy is a kind of clean renewable energy, which is also relatively mature in technology, with largescale development conditions and prospect for the commercialization. The development of wind energy is a systematic project, involving policy, law, technology, economy, society, environment, education and other aspects. The relationship among all the aspects should be well treated and coordinated. This paper has discussed the following relationships which should be well coordinated： relationship between wind resources and wind energy development, relationship between the wind turbine generator system and the components, relationship between wind energy technology and wind energy industry, relationship between off-grid wind power and grid-connected wind power, relationship between wind farm and the power grid, relationship between onshore wind power and offshore wind power, relationship between wind energy and other energies, relationship between technology introduction and self-innovation, relationship among foreign-funded, joint ventured and domestic-funded enterprises and relationship between the government guidance and the market regulation, as well as giving out some suggestions.

Pœcilostomatoid copepods parasitic on fishes off the west coast of Africa

Three species of fish-parasitizing poecilostomatoid copepods are redescribed based on material collected off the coasts of Mauritania and Senegambia. They are: Bomolochus unicirrus Richiardi from Lichia glauca Linnaeus, Taeniacanthus balistae (Claus) from Balistes capriscus Gmelin, and Chondracanthus brotulae Capart from Molva molva (Linnaeus).
