Ditch ecological water treatment method

Abstract

The invention discloses a ditch ecological water treatment method and aims to achieve the objects of high degree of automation, high efficiency, convenience in popularization, low cost, low energy consumption, low maintenance load, high efficiency and the function of overload prevention.. According to the technical scheme, aquatic plant collecting equipment is arranged in a ditch; the eutrophic water body is subjected to plant collection; the collecting equipment comprises a roller body; the roller body comprises a driving shaft, a first telescopic frame, a second telescopic frame connected tothe output end of the first telescopic frame and a plurality of aquatic plant collecting devices arranged at the output end of the second telescopic frame. The first telescopic frame comprises two input ends, which are movably connected and are connected to the driving shaft; shear pins are arranged at the two input ends of the driving shaft and the two input ends of the first telescopic frame. The invention belongs to the technical field of water environment treatment and ecological remediation.

Description

technical field [0001] The invention relates to the technical field of water environment treatment and ecological restoration, and more specifically relates to a ditch ecological water treatment method. Background technique [0002] At present, ditches are the focus of water environment governance and ecological restoration. Due to the loss of balance between the input and output of nutrients, the distribution of species in the water ecosystem is unbalanced, and the growth environment of aquatic plants is mild, and a large area of ​​wild growth covers the water body, destroying the system. The flow of energy causes the entire water ecosystem to gradually perish. [0003] At present, for the treatment of polluted water bodies, there are: physical method, chemical method and biological method. Physical methods usually use physical methods to clean up pollutants in ditches, such as sediment dredging, mechanical algae removal, weeding, etc.; however, physical methods can only r...

AI Technical Summary

Problems solved by technology

Physical methods usually use physical methods to clean up pollutants in ditches, such as sediment dredging, mechanical algae removal, weeding, etc.; however, physical methods can only remove pollutants, and cannot fundamentally solve the problem of river water pollution. pollution problem

The chemical method is to use chemical methods to purify the polluted river water, often by throwing chemicals such as flocculants, herbicides, etc.; however, chemical methods treat water bodies with serious chemical residues, which are likely to cause secondary pollution

Biological methods include: use suspended fillers as bio-film carriers to study the treatment effect of biofilm technology on polluted ditch sewage. This technology has a very significant effect on the treatment of COD and ammonia nitrogen, but it has limitations for water bodies with more complex types of pollutants. Large; the application of exogenous microorganisms to black and odorous water bodies can significantly improve the water quality, and the state of black and odorous water bodies has been improved to varying degrees. It is more complicated; build an ecological floating island and use aquatic animal and plant restoration technology to treat water quality. This technology can effectively improve water quality, increase DO, and reduce nitrogen and phosphorus indicators. However, due to the limitation of plant growth cycle, the purification efficiency is low, and Plants need to be collected regularly; compared with the traditional aeration method, the microporous oxygen-increasing aeration technology can uniformly increase oxygen in deep water, balance the water ecological environment, and improve water quality, but the treatment cycle is longer and the effect is not obvious

[0004] At the same time, the existing aquatic plant collection equipment suitable for ditches usually uses a motor as a power source to link the roller body to drive the aquatic plant collection device to rotate to realize the collection of plants and sundries in the water body. Since the roller body lacks an overload protection device, In complex and changeable ditches, the aquatic plant collection device is easy to be overloaded or stuck. When overloaded or stuck, the device is easily damaged and has a low service life. The working area is not adjustable. When it gets stuck, it is difficult to troubleshoot later. It cannot work in complex waters. There are fewer types of aquatic plants that are applicable and the working efficiency is low.
