Rainwater collecting, purifying and reusing system

Abstract

The invention discloses a rainwater collecting, purifying and reusing system. The rainwater collecting, purifying and reusing system comprises a rainwater collecting and purifying component, a water storage pool, an underground rainwater purifying all-in-one machine, a clean water pool and a water supplying system; the water storage pool is connected with a rainwater flow draining and filtering device and is buried in the underground; the underground rainwater purifying all-in-one machine is connected with the water storage pool through a water inlet pipeline and a pressure releasing and water returning pipe and provided with a water outlet pipeline; the clean water pool is connected with the water outlet pipeline of the underground rainwater purifying all-in-one machine and a tap water supplementing pipeline; the water supplying system is used for supplying water to all water utilization systems and performing back washing on a water storage module of the water storage pool. The rainwater collecting, purifying and reusing system is adopted to treat rainwater, and water obtained through collecting treatment is better in water quality and can be used for car washing, landscape-used water, greening-used water, toilet flushing and the like; recycling and reusing of the rainwater are achieved, and a large quantity of water resources are saved.

Description

Technical field [0001] The present invention relates to the technical field of rainwater collection, purification and reuse, in particular to a rainwater collection, purification, treatment and reuse system. Background technique [0002] Urban construction has caused a lot of impervious ground, roofing, concrete and asphalt pavements. The runoff coefficient of such pavements is generally 0.9, which means that nearly 90% of the rainfall will cause ground runoff loss. This is not only a huge waste of water resources, but also It also increases the burden of urban drainage facilities and increases the probability of urban rain and flood disasters. According to relevant statistics, more than 400 of the more than 600 cities across the country are short of water, and more than 110 are seriously short of water. On the one hand, urban water resources are in short supply, and on the other hand, urban waterlogging and runoff pollution frequently occur. As a kind of abundant water resourc...

Problems solved by technology

[0002] Urban construction has resulted in a large number of impermeable ground, roofs, concrete and asphalt pavements. The runoff coefficient of such pavements 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
