Process and device for emergent salvage of algae bloom

Abstract

The invention relates to a process and a device for emergent salvage of algae bloom. The process is completed all in only one device and includes the following steps of collection, separation, flocculation and medicine addition, dehydration, mud discharge and cleaning. The device used in the process includes a water collection tank, a water inlet pump, an algae-water separator, an automatic medicine addition device, a fold screw dewatering machine, an algae mud receiving tank, and a cleaning pump, wherein all of the units are arranged on one ship body. The water collection tank, the water inlet pump, the algae-water separator, the fold screw dewatering machine and the algae mud receiving tank are successively connected in series through pipelines from an input end to an output end. The process is carried out in the sequence of algae and water collection, algae-water separation and volume reduction and dewatering. Operations of collection, separation, flocculation and medicine addition, dehydration and mud discharge are completed in a whole device. The process, compared with a conventional algae bloom emergent salvage process, has reasonable design and low device size, simple operations and stable operations, and can effectively solve the defects in manual salvage in the prior art. The process and the device are used for the emergent salvage of algae bloom.

Description

technical field [0001] The invention belongs to algal bloom emergency salvage equipment, in particular to an algal bloom emergency salvage treatment process and equipment. Background technique [0002] In recent years, water eutrophication has become a global water environmental pollution problem, and some large lakes and reservoirs in various places in my country have successively shown eutrophication. Due to the aggravation of water eutrophication, it provides rich nutrients for algae outbreaks. , blue-green algae multiply, which leads to the outbreak of blue-green algae blooms. In just a few days, algae can become the absolute dominant species in the entire water source, inhibiting the growth of other organisms. In addition, dead plankton and fish float in it, which not only makes the original Clean, clear, and transparent water bodies become mixed in color, destroying the ecological landscape of the water area, directly endangering the water quality of water sources, and s...
