Method for controlling excessive multiplication of harmful algae in fresh water by straw

一种利用秸秆控制淡水有害藻类过度繁殖的方法

Abstract

Health and safety of people are endangered by mass propagation of harmful algae in fresh waters such as lakes, reservoirs and rivers. The method for controlling algae bloom at present respectively has strong points, but has considerable boundedness, or limited effect or large cost, or has secondary pollution because of adding chemical substances, especially cannot solve the excessive multiplication of the harmful algae in a large range. The invention provides a method for controlling excessive multiplication of harmful algae in fresh water by a straw, and belongs to the technical field of water eutrophication treatment. The method is simple and effective and low in cost, and can easily restrain excessive multiplication of the harmful algae in the fresh water on a large scale. By adopting the method, a lot of agricultural wastes, namely straws are adopted as raw materials. Therefore, the method is wide in source, and convenient to carry out, and can be carried out in waters such as rivers, lakes and reservoirs on a large scale.
湖泊、水库、河流等淡水水体中有害藻类的大量繁殖危害着人们的健康与安全。目前控制藻华的方法各有所长,但均具有相当的局限性,或者效果有限、或者耗费巨大、或者引入化学物质存在二次污染,尤其是都无法大范围的解决有害藻类的过度繁殖。本发明提供一种利用秸秆控制淡水有害藻类过度繁殖的方法,属于水体富营养化治理技术领域。该方法简单有效、廉价、易于大规模抑制淡水有害藻类过度繁殖。该方法采用大量存在的农业废弃物——秸秆为材料,来源广泛,实施方便,可在河流,湖泊,水库等水体中大规模实施。
