Technical Field
The utility model belongs to the technical field of water purification device, specifically a eutrophic river course duckweed cleaning device.
Background
The water eutrophication refers to the phenomenon of water quality pollution caused by excessive content of nutrient salts such as N, P in the water. The essence of the method is that the species distribution of the water ecosystem is unbalanced and a single species grows excessively due to the unbalanced input and output of nutritive salt, so that the flow of substances and energy of the system is damaged, and the whole water ecosystem gradually goes to death.
The prevention and control of eutrophication is the most complex and difficult problem in water pollution treatment because the nitrogen and phosphorus nutrients causing eutrophication of water quality due to the complexity of ① pollution sources are both natural and artificial, and are both exogenous and endogenous, which brings difficulty to the control of the pollution sources, and ② high difficulty in removing the nutrients is not available, so far, any single biological, chemical and physical measures can completely remove the nitrogen and phosphorus nutrients in the wastewater.
In the river channel, duckweed is easy to rapidly propagate after water eutrophication, and duckweed is decomposed by aerobic microorganisms after death, so that dissolved oxygen in water is continuously consumed, or the duckweed is decomposed by anaerobic microorganisms, and gases such as hydrogen sulfide and the like are continuously generated, so that the water quality is deteriorated from two aspects, and fishes and other aquatic organisms are killed in large quantity. During the decay process of algae and other plankton residues, a large amount of nutrients such as nitrogen, phosphorus and the like are released into water for the utilization of new generation of algae and other organisms. Therefore, the eutrophic water body is difficult to self-purify and restore to a normal state even if the source of external nutrient substances is cut off.
When eutrophic river channels are treated, duckweed cleaning is very necessary, labor intensity is high when duckweeds are manually cleaned, and a large amount of labor is consumed, so that the development of a device capable of automatically cleaning duckweeds is very necessary.
