Rainwater Harvesting and Utilization System

Abstract

The invention provides a rainwater collection and utilization system, which collects, purifies, and recycles rainwater, including: rainwater collection and purification channels, water storage containers, rainwater pipes, overflow weirs, rainwater wells, and rainwater reuse pipes; after purification The quality of the rainwater is good, and it is collected and stored in the underground water storage container. When necessary, the purified rainwater can be extracted for reuse; when a large amount of runoff flows into the rainwater collection and purification channel, the rainwater cannot penetrate into the purification layer in a short time When the water level reaches the height of the overflow tank at the end, the excess rainwater will flow into the rainwater well, and the unpurified rainwater will be transported to the sewage plant through the rainwater pipe for treatment.

Description

technical field [0001] The invention relates to the fields of urban domestic sewage, organic waste water in food industry and agriculture, and rainwater treatment, in particular to a rainwater collection and utilization system. Background technique [0002] Urban construction has resulted in a large number of impervious surfaces, roofs, concrete and asphalt surfaces. The runoff coefficient of such road surfaces is generally 0.9, which means that nearly 90% of the rainfall will form surface runoff loss. This is not only a huge waste of water resources, but also It also increases the burden on urban drainage facilities and increases the probability of urban rainwater flood disasters. According to relevant statistical data, more than 400 of the more than 600 cities in the country are short of water, and 110 are seriously short of water. On the one hand, urban water resources are scarce, and on the other hand, urban waterlogging and runoff pollution frequently occur. As a rela...
