摘要
根据食物链中Ｅｌｔｏｎｉａｎ金字塔的形态和Ｋａｌｋｗｉｔｚ提出的河流污染沿程变化分带的概念，提出了改变生态条件培养高一层次生物吃掉藻类的除藻方法，并在工艺上应用浮动生物滤清器解决了这一问题。取得了较好的除藻效果。
he form of an Eltonian pyramid of numbers in the food chain is researched and the concept proposed by Kalkwitz that river contaminations varied along distance are divided into several zones is also researched. The new method to remove algae proposed by the author is to change the ecological condition and culture organisms of higher level in the pyramid which will eat off the algae. This method has been developed based on the technique applying floating bio-filter equipment and the high efficiency of removing algae is achieved.
