Embodiment Construction

[0021] figure 1 In the cyanobacteria collection and treatment device in the lake shown in , the advection type collection bin 1 is provided with a partition 5 with a gap between the bottom of the advection type collection bin. The dividing plate divides the advection collecting bin into a left collecting bin 6 and a right collecting bin 7 communicated through the gap.

[0022] The right side of the right collecting bin 7 has a water inlet 3 lower than the lake water surface 2. There is an adjusting plate 4 that is detachably connected with the side wall of the advection collection bin below the outer side of the water inlet. The adjustment plate 4 can move up and down relative to the advection type collection bin to adjust the bottom of the water inlet (the top surface of the adjustment plate 4) to be 60mm lower than the water surface of the water body. Drainage device 8 is arranged on the bottom of left collecting bin 6 . The left side of the left collecting bin 6 has a wa...

Abstract

The invention aims at providing a high efficiency and low energy consumption method and a device for collecting and treating blue algae. The method comprises the following steps that: an advection-type collecting bin which floats on the water surface of a water body of the blue algae and is provided with a water inlet is adopted; through the method of putting the water inlet lower than the water surface of the water body of the blue algae and discharging water in the bottom layer of the advection-type collecting bin, the blue algae floating on the water surface of the water body enters the advection-type collecting bin; and the blue algae in the advection-type collecting bin is sent to an air floating device for coagulation, air floating and drying and other treatment.

Description

technical field [0001] The invention relates to a method and a device for collecting and treating cyanobacteria floating on the surface of a water body (such as a lake) for collecting, salvaging, concentrating, drying, and the like. Background technique [0002] At present, the method of collecting and processing the blue-green algae floating in the lake is to adopt artificial fishing with a spoon to go ashore and transport outside, or after gathering the blue-green algae with a net, pump the surface layer of blue-green algae and water to the shore and transport outside. Because the water content of blue-green algae salvaged ashore is high, the efficiency of processing blue-green algae is not high, the transportation volume is large, and the energy consumption is high. Contents of the invention [0003] The object of the present invention is to provide a method for collecting and treating cyanobacteria with high collection and treatment efficiency and low energy consumptio...
