Description
Technical Field
The utility model belongs to the technical field of the water treatment, especially, relate to a multi-functional car is clear away to channel side slope algae mud ecology, be applicable to waters such as channel, river, inland lake and landscape water body.
Background
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-flow water bodies such as lakes, reservoirs and the like is accelerated, so that the breeding of algae is caused, the phenomenon of 'water bloom' is frequently outbreak, the ecological balance of the water bodies is seriously damaged, and the safety of human beings and other organisms is harmed. On one hand, the algae breeding reduces the transparency of the water body, so that sunlight is difficult to penetrate through a permeable layer, the photosynthesis of plants in water is influenced, the supersaturated state of dissolved oxygen is possibly caused, aquatic animals are harmful, and a large amount of fishes die. On the other hand, harmful gases generated by the decomposition of organic substances accumulated on the bottom layer under anaerobic conditions and biological toxins generated by some plankton can also damage fishes; in addition, secondary substances formed by mass propagation of algae cause odor in water, increase the corrosivity 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 transfer project which is carried out by adopting a channel mode, a great amount of mud is attached to the channel side slope besides the breeding of algae, so that an algae-mud mixture is formed. The breeding of algae and sludge deposition at the side slope of the channel seriously affect the water quality, the algae in the water can cause the water body to be fishy, green and black, the odor of most lakes and ponds is caused by substances such as hydrogen sulfide, sulfur, ammonia and the like generated by the death of algae and the oxygen deficiency of the water body, the dead algae are deposited on the side slope and seriously affect the water quality, and more seriously, harmful substances such as algal toxin and the like can be generated, so the treatment process of water plants along the line is impacted, and the water supply cost is increased.
