System and method for ecologically processing black and odorous water body

Abstract

The invention provides a system and method for ecologically processing a black and odorous water body, and belongs to the technical field of water treatment. The system comprises a fixed pile and braided straws, submerged plants with strong roots are planted in braided straws; the bottom of the braided straws is fixedly connected to a plurality of balancing weights through connection ropes; the top of the braided straws is fixedly connected to one end of a limiting rope, the other end of the limiting rope is fixed on the fixed pile; when the system is used, the braided straws are slowly soakedinto the water, after the water above the braided straws becomes clear, the braided straws are precipitated until the submerged plants can be seen, and the steps are repeated until the braided strawscover the bottom mud of the river bed. The water body is purified by an ecological means such as microbes, submerge plants, and the like; the bottom mud is decomposed and absorbed, the submerge plants can be harvested periodically, the water body is purified, the bottom mud is degraded, the cost is low, and the method is simple and effective.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to an ecological treatment system and method for black and odorous water. Background technique [0002] With the continuous development of our country's economy, the pollution of urban river water is deteriorating day by day. Among them, the black and smelly river water has many hazards, such as affecting the lives of residents, endangering human health, destroying river ecosystems, and damaging urban landscapes. Therefore, the treatment of black and odorous water bodies has become a key field of active attention and research by many environmental protection experts. [0003] At present, the treatment method for black and odorous water body is mainly to firstly carry out dredging, and then use water treatment equipment to treat the water body. The dredging steps can be divided into artificial dredging and biological dredging. Manual dredging is the transfer of p...

AI Technical Summary

Problems solved by technology

The dredging steps can be divided into artificial dredging and biological dredging. Manual dredging is the transfer of pollutants. This traditional method will bring secondary pollution, especially the water body sediment containing more oil and heavy metals, which is even more harmful. At the same time, it needs to invest a lot of mechanical equipment and chemical agents for treatment, and the energy consumption is also very high; biological dredging is to add biological bacteria to black and odorous water bodies with relatively small amount of sediment, but this biological bacteria is due to Without a carrier, it is easy to be washed away with the water flow, requiring a large amount of long-term dosing, and the cost is very high, and the added foreign bacteria will also have an unknown impact on the ecological environment of the entire water body

Water body treatment technologies mainly use contact oxidation, filtration and membrane separation technologies. Although these technologies can treat water quality well, they consume a lot of energy, have high long-term operating costs, and slow recovery of the entire water ecosystem.

In addition, submerged plants are often used in the field of water treatment technology. Submerged plants can improve the transparency of water bodies and reduce suspended solids in water, thereby improving the light conditions and dissolved oxygen in water bodies, and providing habitats for various underwater organisms and food to ensure the diversity of water body organisms, but if the submerged plants are directly planted at the bottom of the river, there will be more suspended solids in the water body of the river, resulting in insufficient light conditions at the bottom of the river to support the normal growth needs of submerged plants, and The process of planting submerged plants to the bottom of the river is also complicated, time-consuming and labor-intensive
