Rainwater separating treatment recycling device

Abstract

The invention discloses a device for the treatment and reclamation of rain water based on water quality, comprising a water inlet pipe (1), a recycle-water pipe (32) and a rain water collecting chamber (31). The invention is provided with a rain water treatment device which is used to treat polluted rain water; the water inlet pipe(1) is connected with the rain water treatment device and the rain water collecting chamber(31) respectively; the polluted rain water enters the rain water treatment device for treatment by the water inlet pipe(1), and the treated rain water meets the requirement of the recycle-water on water quality, then the rain water enters the rain water collecting chamber(31), and the rain water meeting the water quality of the recycle-water directly enters the rain water collecting chamber(31); and the rain water collected by the rain water collecting chamber(31) is recycled by the recycle-water pipe(32). The device can treat and utilize the rain water based on different pollution degrees of the rain water, thereby resolving the recycling problem of rain water in housing estates, architectural complexes and areas; and the device not only reduces the pollution load of rain water in cities, but also improves the utilization ratio of rain water resource.

Description

technical field [0001] The invention relates to a rainwater quality treatment and reuse device, which is suitable for collecting and utilizing rainwater from roofs of residential quarters and regional roads. Background technique [0002] my country's per capita water resources are only 2220m 3 , which is 1 / 4 of the world's average per capita level. The shortage of water resources has become an important factor seriously restricting the development of my country's national economy. According to statistics, nearly 400 of the more than 700 cities above the prefecture-level city in the country are short of water or severely short of water, most of which are located in arid and semi-arid areas in the north and northwest of my country. In recent years, the northern region has experienced continuous drought, and most cities are running out of water. The southern surface water is seriously polluted, and groundwater is over-exploited. The comprehensive utilization and protection of ...
