Pitch ecological purification box

Abstract

The invention relates to a Bigui ecological purification box which structurally comprises an outer box body (1), a box cover (2), an ecological area (3), an anti-overflow area (5), a water purification area (11) and a water outlet area (15), wherein the tank cover (2), the water purification area (11) and the water outlet area (15) are located in the outer tank body (1), the ecological area (3) and the anti-overflow area (5) are both located above the tank cover (2), the water purification area (11) is located below the tank cover (2), and the water outlet area (15) is located below the water purification area (11); and pores are distributed on the box cover (2). The method has the advantages that 1) dual purification of plants in the ecological area and the water purification area is realized, so that pollution to water bodies such as rivers and erosion to the pecan caused by rainwater runoff and the like is reduced; the ecological area is arranged to purify water and also has greening and beautifying functions, and the side of the exposed box body is provided with a greening heat insulation plate, so that the box body is attractive while heat insulation is realized; (2) an anti-overflow area and a water distribution pipe are arranged, so that the impact load resistance of the purification box is improved;

Description

technical field [0001] The invention relates to a Bidao ecological purification box, which belongs to the field of water ecological protection. Background technique [0002] Bidao is a composite corridor established by water as a link, with rivers, lakes, reservoirs and estuaries as the carrier, coordinating ecological, safety, cultural, landscape, and leisure functions; through systematic thinking, co-construction, co-governance and sharing, optimize the corridor The ecological, living and production space pattern of the city is formed, forming a safe flood channel with clear water and smooth rivers, and a natural ecological corridor with clear water and green shores and shallow fishes. It retains nostalgia and shares a healthy cultural and leisure walk. High quality The development of ecologically active waterfront economic belt. [0003] However, there are also some unavoidable problems in the construction of the blue channel. Because it changes the structure of the surf...

Problems solved by technology

[0003] However, there are also some unavoidable problems in the construction process of Bidao. Because it changes the surface runoff water system structure on both sides of the river, when precipitation occurs, the total surface runoff and rainwater confluence speed in Bidao will change greatly, which will seriously affect Bidao. Channel function even has a significant impact on river ecology

[0004] Existing engineering measures control pollution through technical measures, namely engineering methods, such as porous pavement and seepage pits. Due to the particularity of river channel construction, it is not suitable for use. Precipitation will quickly infiltrate into the river body through porous pavement and seepage pits, because it plays a small role in filtering and purifying the water body, and the seepage water containing a large amount of surface pollutants will cause pollution to the river body Serious pollution; non-engineering measures, that is, through various non-technical natural ecological technical management measures such as increasing greening vegetation, etc., to carry out terminal treatment of surface runoff. Seepage cannot play a corresponding preventive role; therefore, the research direction is now focused on facilities that are conveniently deployed and combine the advantages of engineering measures and non-engineering measures to assist in the purification of surface runoff or even emergency leakage in Bidao
