近年来,随着水产养殖业的快速发展,增氧机的使用日益普及。如何才能正确使用增氧机,达到改良水质,增加放养密度,提高鱼产量的目的,越来越受到专业户的关注。 一、正确选择增氧机的类型和安装位置,增氧机的种类有叶轮式、水车式、射流式、充气式等。 我国目前常用叶轮式增气机。它具有增氧、搅水和曝气三大功能,它的增氧效果是通过造成水跃、液面更新和负压进气形成,明显优于其它类型增氧机。 增氧机应装置于池塘中央或上风的位置,并且利用插杆或抛锚固定。增氧机的工作水深必须超过叶轮直径的2倍以上,以免叶轮泛起淤泥,恶化水质。
In recent years, with the rapid development of aquaculture, the use of aerators has become increasingly widespread. How to correctly use aerator to achieve the purpose of improving water quality, increasing stocking density and raising fish yield has attracted more and more attention from specialized households. First, the correct choice of aerator type and installation location, aerator types are impeller, waterwheel, jet, inflatable and so on. At present, China commonly used impeller-type airlift. It has oxygen, water and aeration three major functions, its oxygen effect is caused by the water jump, liquid level and negative pressure intake formation, significantly better than other types of aerator. Aerator should be installed in the central or upper pond position, and the use of rod or anchor. Aerator depth of work must be more than 2 times the impeller diameter above, in order to avoid the mud thrown by the impeller, deteriorating water quality.
