Problems solved by technology

The main problems are low hydraulic loading, low treatment capacity and large footprint
[0006] In addition to some inherent limitations, the above methods cannot adapt to the change of the large water level of the river, the two-way and multi-directional changes of the river flow, and the change of the temperature difference throughout the year.

Embodiment Construction

[0019] In the implementation process, combined with the actual situation on site, the specific implementation contents of the above-mentioned purification systems are as follows:

[0020] 1. The road rainwater collection system is to set up rainwater collection channels of appropriate size on both sides of the riverside road. The rainwater collection channels are connected with the rainwater pipes under the road through a drainage weir with a suitable height. The rainwater is discharged to the rainwater filter device through evenly arranged drainage pipes with appropriate diameters in the lower part of the rainwater collection channel for preliminary purification, and the initial rainwater of the rainwater exceeding the set rainfall is still discharged to the rainwater filter device through the drainpipe for preliminary purification. The rainwater that collects the discharge of the drainage pipes under the canal is directly discharged to the rainwater pipes under the road throu...

Abstract

This invention discloses a method for three-dimensional treatment of polluted river water. The purification zone is composed of a water distribution and purification system, a bioreinforcing purification system, and a self-oxygenation biopurification system. The invention uses wet land system as the base, and has such advantages as low investment, good effect, easy management, and simple structure.

Description

technical field [0001] The invention belongs to the technical fields of environmental protection engineering, ecological restoration engineering and water conservancy engineering, and particularly refers to a three-dimensional multidirectional flow wetland method for treating non-point source pollution discharged into rivers and purifying river water. Background technique [0002] At present, there are three methods used to treat waste water by using natural water and soil resources such as ditches, rivers and wasteland ponds at home and abroad: artificial wetland method, oxidation pond method and land filtration method. [0003] Constructed wetland is an ecological pollution control technology that has been popularized and applied for many years at home and abroad. In the prior art, relatively large-scale constructed wetlands are generally combined in a multi-stage series-parallel manner. For wetland combinations in series, the subsurface flow and up-and-down flow methods ...
