Method for controlling lake region bottom sediment pollutant releasing and blue-green alga gathering
The invention discloses a method for controlling lake region bottom sediment pollutant releasing and blue-green alga gathering. According to wave removing and intercepting and prevention and control needs, the interior of a lake is divided into a plurality of sections, and wave removing soldier piles and alga intercepting curtain isolating facilities are arranged segmentally. According to the method, active wave removing measures are combined with measures for reducing releasing of source pollutants in a whole lake region and removing waves and alga intercepting measures, the stormy wave blowing distance is shortened, and therefore disturbance of stormy waves on bottom sediment is relieved, and released bottom sediment pollutants, especially total phosphorus, are reduced. Meanwhile, the isolating facilities also have the function of intercepting blue-green algae, so that the alga converging area in a key prevention and control area is greatly reduced, and the blue-green alga agglomeration degree is reduced proportionally. The technical scheme is suitable for lakes with frequent blue-green alga outbreaks, and is used for changing the living conditions of blue-green alga outbreaks, and the blue-green alga agglomeration degree in the specified area is effectively reduced.
本发明公开了一种控制湖区底泥污染释放和蓝藻集聚的方法。按消浪和拦截防控需求，将湖内划分成若干个区段，分段布设消浪排桩和拦藻帘隔离设施。本发明采取主动消浪措施减少整个湖区内源污染释放和消浪措施与拦藻措施相结合的方法，通过缩短风浪吹程从而减轻风浪对底泥的扰动，减少底泥污染特别是总磷的释放；同时，隔离设施兼有拦截蓝藻的功能，使得重点防控区域的汇藻面积大大减少，蓝藻集聚度同比例下降。本发明提供的技术方案适用于蓝藻频繁暴发的湖泊，用于改变藻类暴发的生境，并有效降低特定区域的蓝藻集聚度。
