Embodiment Construction

[0042] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0043] The technical problem solved by the present invention can be realized by the following schemes:

[0044] (1) interception unit

[0045] Before the incoming water from the upstream river enters the water purification system, it passes through a stainless steel grid (or stainless steel screen) to intercept the coarse garbage and floating objects outside the grid, and the garbage outside the grid is cleaned regularly.

[0046] (2) Preprocessing unit

[0047] Between the grid and the partitio...

Abstract

The invention discloses a stereoscopic ecological corridor system and method for in-situ remediation of a riverway water body. The system comprises an intercepting unit, a preprocessing unit, a wetland unit, a greening filtration unit, a back-flushing unit, a drainage unit and a plant control unit. According to the system and the method disclosed by the invention, technical problems that an existing artificial wetland needs intermittent operation and filler blockage highly possibly occurs after long-term operation are effectively solved; a treatment effect and impact load resistance of the entire system are improved, and an occupied area is reduced; and meanwhile the system has a flood control function. In addition, a complete ecological purification system formed through various optimization technologies realizes organic integration of riverway water environment improvement and water ecological remediation. The system has advantages of being small in occupied area, realizing in-situ treatment in a riverway, free from influence on a drainage demand, good in treatment effect, strong in capacity of removing nitrogen and phosphor, strong in adaptability to impact load, free from mosquitoes and flies, convenient in operation and maintenance management, etc., and is suitable for treating riverways contaminated by domestic sewage and industrial wastewater.

Description

technical field [0001] The invention relates to the technical field of water ecological sewage treatment, in particular to a three-dimensional ecological corridor system and method for in-situ restoration of river water bodies. Background technique [0002] As an important part of the urban landscape, urban rivers not only provide the city with domestic water for residents, but also ensure the city's industrial water, fire-fighting water, and green irrigation. Among the multiple constituent systems of the city, the river channel has the functions of flood control and drainage, landscape culture, ecological environment and rainwater utilization, etc., and has played a positive role in promoting the progress and development of the city. Therefore, building a good urban river ecosystem plays an important role in the development and continuation of human beings from the perspective of sustainable development. [0003] With the rapid development of urban economy and the accelera...
