Abstract

The invention discloses a technology for collecting, storing, purifying and recycling wharf rainwater, and relates to the field of rainwater drainage engineering. The technology is composed of a seepage collecting unit, a rainwater garden and a recycling unit. Rainwater is collected and converged into a spiral-flow type sand settling rainwater well through a drainage ditch and an overflow rainwater opening; the rainwater is primarily settled in the spiral-flow type sand settling rainwater well and then discharged into a rainwater conveying channel, and the rainwater is conveyed to the rainwater garden through the rainwater conveying channel; after being treated by an immobilized multi-layer composite flora material and a dielectric layer filler in the rainwater garden, the rainwater is collected into an underground water collecting tank; and finally, the rainwater in the underground water collecting tank is recycled to each water using point through a recycling pump. The spiral-flow type sand settling rainwater well and the rainwater conveying channel are both made of sponge concrete. According to the water quality characteristics of initial rainwater of a wharf, collection, storage, purification and recycling of the rainwater of the wharf are achieved, pollution of the initial rainwater to a water body is avoided, and the technology has the advantages of being simple and compact in structure, low in operation cost, easy to control, high in rainwater recycling rate, environmentally friendly and the like.

Description

technical field [0001] The invention relates to a process for collecting, storing, purifying and reusing rainwater at a wharf, and belongs to the field of rainwater drainage engineering. Background technique [0002] In the early stage of rainfall, the rainwater dissolves a large amount of polluting gases such as acid gas, vehicle exhaust, and factory exhaust gas in the air. After falling on the ground, it washes away roofs and concrete roads, resulting in a high degree of pollution in the initial stage of rainwater. However, there are loading and unloading operations of coal, ore and other materials at the wharf, which is prone to dust floating on the wharf surface. When it encounters rainfall, the suspended solids content in the initial rainwater is as high as 1000-3000mg / L. If it cannot be properly collected and treated, it may cause obvious pollution to the environment due to flowing into rivers. [0003] The collection of initial rainwater at the wharf generally adopts...
