Efficient blue algae salvaging ship

Abstract

The invention provides an efficient blue algae salvaging ship for improving salvaging and treatment efficiency of the blue algae salvaging ship. The efficient blue algae salvaging ship mainly comprises a ship body, a water decanter, a water pump, a filtration pipeline, a chemical feeding tank, an algae-mud dehydrating machine, a rear drainage pipe and a side drainage pipe. Algae-laden water on thesurface layer in a nose direction is collected into an algae water bin by the water decanter, is pressurized by virtue of the water pump, the pressurized algae-laden water enters the filtration pipeline to be dehydrated and then is conveyed into the chemical feeding tank and the algae-mud dehydrating machine, produced algae cake is loaded into an algae cake bin, tail water discharged by the filtration pipeline and the algae-mud dehydrating machine is discharged out from the stern direction by virtue of the rear drainage pipe and the side drainage pipe. The filtration pipeline is regularly back-washed by lifting the water decanter, switching a valve and utilizing the tail water of the algae-mud dehydrating machine. After blue algae salvaging is finished, water in the algae water bin, a pipeline bin and the chemical feeding tank is discharged outside the ship body by virtue of the water pump and a backwashing pipe, and the algae cake is transported to a shore to be treated. By implementing the efficient blue algae salvaging ship provided by the invention, a significant role is played for controlling blue algal bloom, water bloom and red tide, improving lake water quality, removing phosphorus and nitrogen in water and alleviating water eutrophication.

Description

technical field [0001] The invention belongs to the field of water pollution control and prevention, in particular to a high-efficiency blue algae salvage ship. Background technique [0002] As domestic sewage and industrial and agricultural wastewater bring pollutants such as N and P into lakes, the degree of eutrophication in lakes is increasing, and the prevention and control of eutrophication has become a worldwide problem. The eutrophication of the water body can easily lead to the outbreak of cyanobacteria, resulting in algae blooms, red tides, hypoxia in the water body, and fish death. The algae can also release algae toxins that endanger water safety. The removal of cyanobacteria can not only improve the water body landscape and promote the water ecological balance, but also remove N, P and other pollutants in the water body and reduce the degree of eutrophication in the water body. [0003] There are three types of methods for cleaning blue-green algae: one is to d...
