Description
Technical Field
The invention belongs to the technical field of water treatment, and particularly relates to an underwater cavitation jet cleaning device for removing a channel side slope algae mud mixture, which is suitable for water areas such as channels, rivers, inland lakes, landscape water bodies and the like.
Background
Along with the acceleration of the social industrialization process, a large amount of pollutants containing nitrogen and phosphorus are discharged into water bodies by human beings in production and daily life, and the eutrophication process of slow-flowing water bodies such as lakes, reservoirs and the like is accelerated, so that algae breeding is caused, the phenomenon of 'water bloom' is frequently and violently generated, the ecological balance of the water bodies is seriously damaged, and the safety of human beings and other organisms is endangered. Algae grow on the one hand to reduce the transparency of the water body, so that sunlight is difficult to penetrate through a water layer, photosynthesis of plants in the water is affected, supersaturation of dissolved oxygen is possibly caused, and the algae are harmful to aquatic animals, so that a large number of fishes die. On the other hand, harmful gases generated by decomposing organic substances accumulated on the bottom layer under anaerobic conditions and biotoxins generated by some plankton can also injure fish; in addition, secondary substances formed by mass propagation of algae cause odor in water, increase corrosiveness of the water, and easily cause 'yellow water' in a pipe network under the condition of high water temperature in summer.
In addition, for the major water diversion project adopting the channel mode, a great amount of mud is adhered to the channel side slope besides breeding algae, so as to form an algae mud mixture. Algae breeding and mud deposition on the side slope of the channel seriously affect the quality of water, algae in the water can not only cause fishy smell and greenish and blackish of the water, but also cause the bad smell of most lakes and ponds caused by substances such as hydrogen sulfide, sulfur, ammonia and the like generated by the death of the algae and the lack of oxygen in the water, and dead algae are deposited on the side slope to seriously affect the quality of the water, and more seriously, harmful substances such as algae toxins and the like can be generated, so that the treatment process of water plants along the line is impacted, and the water supply cost is increased. Therefore, the algae mud mixture on the side slope is cleaned, the water body conveying quality is improved, the treatment difficulty of a water plant is reduced, the technical problem which needs to be solved urgently is solved, and the method has important ecological and environmental significance.
At present, in the technology for removing algae mud on side slopes at home and abroad, in order to avoid secondary pollution to water quality, a physical removing method is usually adopted, and the method mainly comprises the methods of manual cleaning, mechanical friction cleaning and the like. By adopting manual cleaning, the labor intensity is high, the efficiency is low, a large amount of dirt can be diffused into water, secondary pollution is caused, and algae mud attachments which are submerged in deep water and positioned in a vision blind area cannot be completely removed. The mechanical friction type cleaning mode has wide application and obvious effect, and can directly remove part of algae mud attachments in the water body. However, the existing mechanical clearing device has complex equipment structure, on one hand, when the clearing device works, the sealing problem caused by underwater mechanical transmission exists, and secondary pollution is easy to generate; on the other hand, there is a disadvantage that the algae grown cannot be eradicated, and the efficiency of the working area is low.
