Ecological purification screen

Abstract

The invention relates to an ecological purification screen. The screen comprises a screen frame which is arranged vertical to a river channel, a physical filter section, an internal electrolysis section and a biological filter section which are arranged on the screen frame sequentially along the water flowing direction, wherein the internal electrolysis section comprises an internal electrolysis treatment zone and an aeration zone which are sequentially distributed from top to bottom; a plurality of internal electrolysis filler balls are dosed in the internal electrolysis treatment zone, and each internal electrolysis filler ball comprises a hollow spherical shell filled with electrolysis filler; and pores are formed in the hollow spherical shells in a sealed manner and enable to-be-treated wastewater to sufficiently contact with the internal electrolysis filler. Compared with the prior art, the ecological purification screen has the advantages that the screen can be directly distributed at the upstream of a to-be-treated river channel, and therefore, the upstream water body with relatively poor water quality can be quickly purified after flowing through the screen system, the downstream water quality can be improved in time, and the problem that conventional equipment delays downstream water body improvement during purification cannot happen.

Description

Technical field [0001] The invention relates to the technical field of treatment and restoration of river and lake water environment, in particular to an ecological purification barrier. Background technique [0002] In recent years, the black and odorous water bodies in cities have been a strong water environment problem that the people have reported strongly, which not only damages the urban living environment, but also seriously affects the image of urban civilization. For the treatment of black and smelly rivers, traditional methods such as chemical treatment, dredging, interception of dams, aeration, and hard slope protection are usually used. Although these methods have quick results and can enhance the stability of river banks, they are hard. Slope protection cannot be planted with aquatic plants, interception dams easily lead to stagnant water formation, high energy consumption of aeration and other shortcomings, which severely damage the water ecosystem and consume large...

Problems solved by technology

But the above-mentioned device can be applied to the purification treatment of general river sewage, but it is very unsatisfactory for the treatment effect of organic matter (especially macromolecular organic pollutants, etc.) During ecological management, the sewage is pumped to the shore equipment for treatment, which leads to the problem that the water quality of the downstream water body still has substandard water quality for a long time during the treatment of the upstream water body.
