A method and equipment for ultrasonic algae removal based on solar power generation

Abstract

The invention provides a method and equipment for ultrasonically removing algae based on solar power generation. The method comprises the following steps: collecting algae-contained water, ultrasonically removing algae, filtering the algae-contained water, and collecting dry algae. The equipment comprises a power unit, an algae collecting unit, an algae filtering unit, an algae drying unit, a dry algae storage bin and a bearing body, wherein the power unit is composed of a solar power generator set, a storage battery, an inverter and a power supply controller, and the bearing body is used for bearing the power unit, the algae collecting unit, the algae filtering unit, the algae drying unit and the dry algae storage bin; the algae collecting unit comprises a water storage tank, a forceps clip and an algae removing tank; the algae filtering unit sequentially comprises a drainage tank, a shaker and a filtering tank from bottom to top, and a scraper and a filtering layer are arranged in the filtering tank; the algae drying unit is composed of a preheating algae drying unit, a drying box and a steam outlet pipe with a gas pump. The method has a good algae removing effect and cannot generate secondary pollution to water. The equipment integrates algae removing, algae drying and algae collecting functions and is thorough in algae removal and low in algae removal cost.

Description

technical field [0001] The invention relates to an algae removal method and equipment, in particular to an ultrasonic algae removal method and equipment using solar energy as a power source. Background technique [0002] In the past ten years, due to the eutrophication of water bodies, large-scale cyanobacteria blooms have been born, which poses a major threat to aquatic organisms and drinking water sources. The algae toxins produced by the degradation of algae during decay pose a threat to human and biological health. At present, Many methods for removing algae and blooms have been developed at home and abroad, which can be divided into physical methods, chemical methods and biological methods according to their removal principles. [0003] The physical method is mainly to collect and treat cyanobacteria, such as manual salvage, algae removal boat, etc. This method has a fast effect and is more suitable for when the concentration of algae is high and severe cyanobacteria bl...

AI Technical Summary

Problems solved by technology

[0003] The physical method is mainly to collect and treat cyanobacteria, such as manual salvage, algae removal boats, etc. This method has a fast effect and is more suitable for when the concentration of algae is high and severe cyanobacteria blooms have formed. Low concentrations of cyanobacteria are not applicable when cyanobacteria blooms have not yet formed, and in the process of algae removal, some algae removal ships use fuel-powered systems, and the exhaust gas generated by them will inevitably pollute the environment and consume non-renewable energy , while part of the electricity consumption limits its mobility flexibility

[0004] The chemical method is based on the chemical and biological characteristics of cyanobacteria blooms, spraying various disinfectants into the water body, but this method is easy to cause secondary pollution to the water body, and cannot be applied to the removal of cyanobacteria blooms in breeding areas

[0005] The biological method is to put filter-feeding plankton such as silver carp, bighead carp and mussels into the water body through the food chain in the water body, which can inhibit the reproduction of Microcystis. The ingestion of cyanobacteria is not selective, and the ability to remove cyanobacteria is limited, so it can only be used as an auxiliary removal method
