With the improvement of living standard, artificial lakes and artificial lake channels are continuously emerging in urban green land, park construction and large-scale landmark buildings. However, the enrichment of nutrients such as nitrogen and phosphorus in the water body causes the abnormal proliferation of algae, the generation of bloom or lake indigo, the reduction of water transparency, the reduction of dissolved oxygen and the serious deterioration of water quality, which not only affect the beauty but also destroy the ecological balance to cause certain diseases and the like, so the water body needs to be treated.
The physical methods commonly used in water body treatment include aeration, sediment dredging and water-induced scouring. Aeration is to artificially aerate the water body through an aeration system, so that dissolved oxygen in the water is increased, the activity of aerobic microorganisms in the water body is improved, and the degradation of organic matters is further increased. The sediment dredging is to directly remove sediment deposited at the bottom of the lake channel by using a certain mechanical device, so as to take away deposited nitrogen, phosphorus and the like, and play a role in increasing the effective volume of the lake channel and reducing nutrient substances. The water diversion and flushing is to introduce water in other water bodies with better water quality into the polluted lake channel to replace or dilute the polluted water body, so as to play a role in relieving the pollution of the water body in the lake channel. However, for the artificial waterscape in the park, most of the artificial waterscape are in a closed form, the water flow of the water body is slow, the pollutant concentration is high, if physical means such as water diversion and washing, aeration, sediment dredging and the like are adopted for purification, the cost is too high, and the temporary solution is not a permanent solution. In the prior art, the purpose of removing pollution and restoring a water body ecosystem by means of absorbing, degrading, converting and the like of pollutants in a water body by microorganisms or animals and plants is a trend of treating the water body.
However, the existing water body treatment method is easy to destroy the original ecological environment, occupies a large amount of land resources and is easy to generate secondary pollution; in addition, the sewage treatment equipment also has the defects of higher equipment cost, higher running cost, unobvious treatment efficiency and effect, high maintenance rate, low automation degree and the like. And the general water body equipment is fixed, the water quality treatment range is limited, the sewage needs to be conveyed into the treatment equipment from a distance, and the treatment time is long.
