A plant grill for improving the water quality of river canals

Abstract

The invention belongs to the technical field of surface source pollution (non-point source) control, and specifically relates to a plant grill for improving the water quality of rivers and canals. The plant grid is mainly composed of the grid, the outer stabilizing wall (including the water inlet wall, the drainage wall, etc.) and the filling area. It adopts steel-concrete or brick-concrete structure and is installed downstream of the grille. The invention is used to grow microorganisms and aquatic plants, improve the water quality of cement-hardened ditches and inland river runoff, and mainly solve the problem that the hardening of ditches and inland river embankments and riverbeds makes it difficult to grow plants in them, and the smooth inner interface lacks the medium, cement and Concrete products cut off the contact between the runoff and the soil, and lose the self-purification ability of the soil. It is suitable for the treatment of rural agricultural runoff and urban runoff, especially for the treatment of cement-hardened ditches and inland river runoff in the future.

Description

technical field [0001] The invention belongs to the technical field of surface source pollution (non-point source) control, and in particular relates to a plant grill for improving the water quality of rivers and canals. Background technique [0002] In recent years, cement and concrete products have been widely used in the construction of urban and rural drainage channels and inland rivers, which prevents the growth of weeds in channels and inland rivers, facilitates the smooth drainage of channels and inland rivers, and ensures the flood discharge of channels and inland rivers. At the same time, cement The hardened canal also effectively maintains the water and soil erosion of the canal and inland river, reduces the labor and mechanical expenses caused by dredging the canal and inland river, and reduces the management cost. But at the same time, the hardening of ditches and inland river embankments and riverbeds makes it difficult for plants to grow in them; the smooth inn...

Problems solved by technology

[0004] The purpose of the present invention is to provide a plant grid for improving the water quality of river canals (including inland rivers or ditches), so as to solve the problem of hardening of ditches and inland river embankments and riverbeds, making it difficult for plants to grow in them, and the smooth inner interface lacks the attachment and growth of microorganisms The medium, cement and concrete products cut off the contact between the runoff and the soil, and lose the self-purification ability of the soil, etc.
