A pavement rainwater collection and utilization system

Abstract

The invention discloses a system for collecting and utilizing road surface rainwater. The system comprises water pump adapters, a sidewalk for the blind, a sidewalk, a cover plate of the sidewalk, efficient water draining curbstones and a sewer, wherein the sidewalk and the sidewalk for the blind cover the sewer, the cover plate of the sidewalk and the sewer penetrate through the whole road length, supporting wire frames are vertically mounted on the sewer along the road length, primary purifying pools are arranged under the sewer, water storing pools are arranged under the primary purifying pools, two water intakes are formed in the water pump adapters, the two water intakes are respectively connected with the primary purifying pools and the water storing pools through communicating pipes, floating ball devices are mounted in the primary purifying pools and the water storing pools, the primary purifying pools and the water storing pools, which are in upper-lower arrangement are connected vertically, multi-layer filtering layers are arranged at the vertical connecting positions and are used for purifying water. The system disclosed by the invention has the advantages of being simple in structure, multiple in functions, high in utilizing rate of rainwater, and obvious in water saving effect, and can be widely applied to road rainwater collection.

Description

technical field [0001] The invention relates to a pavement rainwater collection and utilization system, which relates to the field of water resource recycling. Background technique [0002] my country is a country that is very short of water resources. The per capita possession is only 2,220 cubic meters, which is 1 / 4 of the world's average level. It is listed as one of the 13 water-poor countries by the United Nations. The uneven distribution of water resources in time and space has further exacerbated the contradiction of water resources. With the rapid development of social economy and the acceleration of urbanization, the utilization of water resources is imperative. Collecting road runoff nearby can greatly reduce the cost of irrigating green belts and water absorption by sprinklers. The collection and multi-use of road rainwater can realize water saving, conservation and protection of water resources, control urban soil erosion and waterlogging disasters, reduce wate...

Problems solved by technology

[0003] In the prior art, such as the Chinese patent "A Road Rainwater Collection and Utilization System" (authorized announcement number: CN202416116U), which discloses a rainwater collection and utilization system, the system includes: rainwater flow ditch, water storage tank, Together they form a rainwater collection device. The disadvantage of this system is that the rainwater on the road in the early stage flows into garbage, and the filter on the water storage tank cannot prevent the entry of small-volume garbage. The bottom of the water storage tank is connected by a horizontal connecting pipe. The water in the water storage tank at the highest point during the slope will flow away and fail to achieve the purpose of water storage

When absorbing water, only one or several preliminary purification pools can be absorbed, but not all the water in the preliminary purification pools, causing serious inconvenience

The collected water can only be used to irrigate the green belt, and the water needs to be powered by the system, which is not convenient and economical
