Description
Technical Field
The invention relates to the field of eutrophication treatment of river and lake water bodies, in particular to a mobile algae water treatment system and a treatment method thereof.
Background
Eutrophication of water body refers to water pollution phenomenon caused by excessive nutrient salt content of N, P and the like in water body. Under proper climatic conditions, after the water body is eutrophicated, the water bloom phenomenon mainly comprising algae appears on a large scale. Since algae cells with air bags are basically suspended on the water surface to grow, dead algae can float in clusters on the water surface, thus aggravating the deterioration of water quality. As the economy evolves and the population increases, N, P contaminants discharged into the river and lake increase dramatically, resulting in frequent algae outbreaks.
At present, various physicochemical and biochemical algae removal methods are tried in various places in China, and the problems of low treatment efficiency, high treatment cost and the like exist, so that the method is difficult to popularize on a large scale. At present, manual or mechanical salvaging is mainly used in all places, when the size of the algae is several micrometers, the currently adopted salvaging machine has lower precision, the algae can not be collected, only the algae which are integrated on the surface of river water or lake water can be collected, and further the spreading of the water bloom phenomenon can not be controlled. Mechanical salvaging can be effectively implemented only when large-scale water bloom occurs, and when the density of algae reaches 3.5 multiplied by 10 6 When the number is less than the specific value, it is difficult to perform preventive salvage.
In addition, the Chinese patent application No. 202110080168.8 discloses a sewage treatment algae removal system and an algae removal method, wherein the sewage treatment algae removal system comprises a pretreatment unit, an intermediate lift pump room, a deep treatment unit, a subsequent treatment unit and a dosing device; the pretreatment unit, the middle lifting pump room, the advanced treatment unit and the subsequent treatment units are sequentially connected through pipelines; the dosing device comprises a medicament tank, a discharging pump, a flowmeter and a dosing tube, wherein the medicament tank, the discharging pump and the flowmeter are sequentially connected through pipelines, and finally are connected with the middle lifting pump room through the dosing tube. The invention mainly aims at the algae breeding phenomenon of the sewage advanced treatment unit, and the high-efficiency disinfectant is added into the intermediate lifting pump room between the biological reaction tank and the high-efficiency sedimentation tank, so that thalli and algae cells in the water body are killed by the high-efficiency disinfectant. However, when the invention is applied to a sewage treatment plant, when the water surface is relatively open to a large lake or reservoir, the invention cannot be matched with a ship to carry out moving operation, and when the algae density is low, the invention cannot carry out preventive algae removal so as to slow down the occurrence of water bloom.
