Abstract

本发明公布了一种利用着生藻类去除浅水型湖泊中氮磷的方法，包括人工基质的选择、人工基质设置区域的选择、人工基质设置方法、着生藻类的清除和循环去除等步骤。本发明具有两次去除水体中氮磷的优点：首先是通过着生藻类在水体中的增殖消耗水体中一定量的氮磷，其次是人为清除人工基质上的着生藻类再次去除水体中一定的氮磷。同时本发明具有对水体本身没有污染，操作简便，制作工艺简单，费用低等优点。

Description

利用着生藻类去除浅水型湖泊中氮磷的方法
技术领域
本发明涉及一种利用着生藻类去除浅水型湖泊中氮磷的方法。
背景技术
着生藻类广泛存在于自然界水体中，通过吸收代谢利用、吸附和络合等过程去除水体污染物质，具有生物量大，水质响应灵敏，氮磷去除效果好，藻类细胞回收利用价值高等优点，适合用作富营养化水体的生态修复技术。
随着我国经济的持续发展，外来污染源大量进入水体，造成天然水体不同程度的富营养化。为了我国渔业的可持续发展，各地采取生态修复技术来遏制水域环境恶化，但目前的生态修复技术更多的集中在水生野生动物的种群补充上面，忽略了着生藻类这一微观群落对水体净化的作用。
发明内容
本发明目的在于提供一种利用着生藻类去除浅水型湖泊中氮磷的方法。
本发明为实现上述目的，采用如下技术方案：
利用着生藻类去除浅水型湖泊中氮磷的方法，包括以下步骤：
（1）人工基质的选择：
     选取大小为1m×1m的表面毛糙木板作为人工基质；
（2）人工基质设置区域的选择：
     在浅水型湖泊岸边，距离岸边3-5m处，选择水流冲击较小的地方作为人工基质的设置区域。 区域与区域间隔距离500-600m；
（3）人工基质设置方法：
     所述人工基质倾斜悬浮放置在水中，人工基质的底边放置在距岸边较远处，保持该边与岸边平行；每个选择区域中设置人工基质3-5块，每块人工基质间隔2-3m；
（4）着生藻类的清除：
       人工基质设置20-25天后，取出水体中的人工基质，利用毛刷将人工基质上的着生藻类刷洗干净；
  （5）循环去除：
       根据需求重复（4）、（5）两个步骤多次。
本发明具有两次去除水体中氮磷的优点：首先是通过着生藻类在水体中的增殖消耗水体中一定量的氮磷，其次是人为清除人工基质上的着生藻类再次去除水体中一定的氮磷。同时本发明具有对水体本身没有污染，操作简便，制作工艺简单，费用低等优点。
具体实施方式
一种利用着生藻类去除浅水型湖泊中氮磷的方法，包括以下步骤：
（1）人工基质的选择：
     选取大小为1m×1m的表面毛糙木板作为人工基质；
（2）人工基质设置区域的选择：
     在浅水型湖泊岸边，距离岸边3-5m处，选择水流冲击较小的地方作为人工基质的设置区域。 区域与区域间隔距离500-600m；
（3）人工基质设置方法：
     所述人工基质倾斜悬浮放置在水中，人工基质的底边放置在距岸边较远处，保持该边与岸边平行；每个选择区域中设置人工基质3-5块，每块人工基质间隔2-3m；
（4）着生藻类的清除：
       人工基质设置20-25天后，取出水体中的人工基质，利用毛刷将人工基质上的着生藻类刷洗干净；
  （5）循环去除：
       根据需求重复（4）、（5）两个步骤多次。
