Method for removing periphytic algae by using sand-containing water flow
The invention discloses a method for removing periphytic algae by using sand-containing water flow. The method comprises the following steps: collecting the biomass density of the periphytic algae in a downstream river of a reservoir; when the biomass density is larger than the preset density, the water flow velocity and the water body sand content of the river under various pulse flows are obtained; calculating the washing removal rate of each kind of periphytic algae under all pulse flows; selecting corresponding pulse flow required when the same algae is greater than a preset target removal rate, and counting all pulse flow required to scour and remove the algae to reach the target removal rate; and selecting an optimal value in the counted pulse flow according to the water storage amount in the reservoir, and starting the reservoir to discharge the pulse flow to remove periphytic algae.
本发明公开了一种含沙水流对着生藻类的去除方法，其包括采集水库下游河流中着生藻类的生物量密度；当所述生物量密度大于预设密度时，获取多种脉冲流量下河流的水流速度和水体含沙量；计算所有脉冲流量下着生藻类中的每种藻类的冲刷去除率；选取同一藻类大于其预设目标去除率时所需对应的脉冲流量，统计出所有需要冲刷去除藻类达到目标去除率的脉冲流量；根据水库中的水存储量，选取统计的脉冲流量中的最优值，启动水库下泄脉冲流量对着生藻类进行去除。
