Biological filtration and collection green belt unit for rainwater on both sides of road

Abstract

The invention discloses a green belt unit for biological filtration and collection of rainwater on both sides of a road, comprising a rainwater collection well, a left biological filtration system, a right biological filtration system and a drainage pipeline. The biological filtration system on the left and the biological filtration system on the right are symmetrically arranged and have the same configuration characteristics; the overflow pipe outlet is set at the lower part of the rainwater collection well. It is connected with the rainwater collection well. The neck of the rainwater collection well is equipped with a pump. The outer edges of the water distribution channels on the front and rear sides of the water distribution channel are provided with water distribution channel water inlets. The distance between the adjacent water distribution channel water inlets is 5m. The length is 1m, and a wire mesh is installed in the water inlet of the water distribution channel; multiple groups of irrigation perforated pipes are connected between the front and rear water distribution channels, and the spacing between the left and right adjacent irrigation perforated pipes is 1m. The present invention collects and stores urban rainwater, realizes biological filtration of urban rainwater, and meets the requirements of receiving water bodies for rainwater.

Description

technical field [0001] The invention belongs to the field of urban rainwater collection and utilization, in particular to a green belt unit used for biological filtration and collection of rainwater on both sides of roads. Background technique [0002] With the continuous development of the urbanization process, the impermeable concrete floor has increased significantly, and the urban permeable floor area has gradually shrunk. As a result, when heavy rainstorms and floods occur in the city, the heavy rain cannot be infiltrated in time to reduce the flood peak, resulting in urban waterlogging. At the same time, rainwater contains a large amount of nutrients, suspended particles, and heavy metals. If these substances are directly discharged into the recipient water source without treatment, it will cause serious pollution of the recipient water source. Most parts of our country have a monsoon climate, and the annual rainfall distribution is uneven. During the flood period, the...

Problems solved by technology

At present, the treatment methods for heavy rain in cities in my country are mainly based on drainage, supplemented by storage, and there is little practice of rainwater filtration.
