Rainwater collecting and cleaning treatment system and rainwater collecting and cleaning method thereof

Abstract

The invention provides a rainwater collecting and cleaning treatment system and a rainwater collecting and cleaning method thereof. The rainwater collecting and cleaning treatment system comprises gullies, a filtering basin, a collecting basin and a water storage tank which are sequentially connected using a pipeline. The gullies are divided into a house rainwater gully and a road surface rainwater gully. The house rainwater gully is arranged directly under a water outlet of a house roof drainpipe. Both upper and lower ends of the house rainwater gully are open, and a first filter mesh and a second filter mesh are arranged at the upper and lower ends, respectively. An air vent is provided in a sidewall of the house rainwater gully, and the air vent is a one-way valve hole for unidirectionally exhausting air to the outside. The edge of the top of the road surface rainwater gully is lower than the road surface where the road surface rainwater gully is located. Both upper and lower ends of the road surface rainwater gully are open, and a third filter mesh and a fourth filter mesh are arranged at the upper and lower ends, respectively. The rainwater collecting and cleaning treatment system in the invention is simple in design and reasonable in structure, and can achieve collecting and cleaning rainwater for utilization.

Description

technical field [0001] The invention belongs to the field of rainwater collection, purification and reuse, and in particular relates to a rainwater collection, purification and treatment system in residential quarters. Background technique [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. According to relevant statistical data, more than 400 of the more than 600 cities in the country are short of water, and more than 110 are seriously short of water. On the one hand, urban water resources are scarce, and on the other hand, problems such as urban waterlogging and runoff pollution occur frequent...
