Bloom alga blocking, enrichment collection and alga removal system

Abstract

The invention discloses a bloom alga blocking, enrichment collection and alga removal system. The system comprises at least one alga collection unit, a blue alga conveying main pipe, a boost pump anda control platform. Each alga collection unit is composed of an enclosure device and an alga collection device. Each enclosure device is fixed in water in a V shape and comprises a first floating body, a skirt body and a balance weight, wherein the balance weight is sunken to water bottom mud, the first floating body floats on the water surface, and the skirt body is connected between the first floating body and the balance weight. The open face of the V shape of each enclosure device faces an open water area. Each alga collection device is arranged in the included angle of the V shape formedby the corresponding enclosure device and comprises an alga suction head, a second floating body, an alga suction pump and a collection pipeline, wherein the alga suction pump is connected with the alga suction head and controls the alga suction head to extract algae, and the second floating body is connected to the alga suction head. Each second floating body is connected with the corresponding first floating body through a mooring rope. The collection pipelines collect the algae extracted by the alga suction heads, and the algae are conveyed to the blue alga conveying main pipe. By means ofthe system, the removal efficiency of algae of the lakeside blue alga enriched area can be remarkably improved, the process is simple, and the operation and maintenance cost is low.

Description

Technical field [0001] The invention relates to the technical field of full-line continuous electric harvesting of algae blooms, and more particularly to a device for effectively intercepting and enriching blooms and algae with efficient diversion and harvesting, and is particularly suitable for intelligent interception of algae on the surface of water bodies after algae blooms are formed in freshwater ecosystems And collection, especially suitable for rapid and efficient algae removal in the coastal zone of rivers and lakes. Background technique [0002] Due to rapid economic development and rapid population growth, water ecosystems have been severely polluted, and the eutrophication of many water bodies has increased, causing the proliferation of algae. In some water bodies, serious blue algae blooms have even occurred, and water resources have been seriously degraded. Algae blooms mostly occur in high-temperature seasons. Algae blooms are easy to accumulate in the lakeside zon...

Problems solved by technology

Removing large-scale accumulated cyanobacteria requires a large number of algae fishing platforms, and the operating cost is high. It can only be used as an emergency treatment or in a few specific locations. The scale of algae fishing is limited

Large-scale algae fishing boats are also used to remove cyanobacteria blooms, but large-scale algae fishing boats are often only suitable for deeper and larger water surfaces, and the cyanobacteria blooms enriched in coastal shallow water areas, especially coastal wetlands, cannot be removed

Some areas even directly use submersible pumps to pump high-concentration algae water, while the traditional blue-green algae suction port is not specially treated. During the suction process, the low-algae-content lake water in the lower layer is quickly replenished, which reduces the concentration of the extracted algae water and reduces the algae removal efficiency. , and increase the cost of subsequent cyanobacteria resource treatment

In order to control large-scale pollutants from entering the algae suction pump, there are usually the following two treatments. One is to set up a trash block (invention patent CN201510506625). This type of trash block is expensive and cannot prevent the entry of garbage behind the enclosure Algae pumping area

One is to directly wrap a layer of small-aperture screen on the suction port of blue-green algae. Large particles of floating debris often block the screen and need to be washed repeatedly, which affects the pumping efficiency and even damages the power pump.
