Description

Building rainwater is collected and ecological system that utilizes

Technical Field

The utility model belongs to the technical field of rainwater is recycled, especially relate to a building rainwater is collected and ecological utilization system.

Background

The sponge city is a new generation of urban rainfall flood management concept, and means that the city has good elasticity in the aspects of adapting to environmental changes, coping with natural disasters caused by rainwater and the like, and can be also called as a water elasticity city. The international generic term is "low impact development storm water system construction". When raining, the utility model absorbs water, stores water, seeps water and purifies water, and when needed, the stored water is released and utilized.

When the early rain falls, the rain water of the first 2 ~ 5mm is generally seriously polluted, the flow rate is relatively small, the rain water dissolves a large amount of polluting gases in the air, such as acid gas, automobile exhaust, factory exhaust and the like, and generally contains a certain amount of toxins influencing plant growth, the toxins can comprise sulfides, salts and the like, even an improper pH value, after the rain water falls to the ground, the early rain water contains a large amount of pollutants, such as organic matters, pathogens, heavy metals, grease, suspended solids and the like due to the fact that asphalt felt roofs and the like are washed, so that the pollution degree of the early rain water is higher and generally exceeds the pollution degree of common urban sewage.

At present, the volume of most of the flow discarding devices is the volume of all initial rainwater, and the volume is overlarge; some devices that drain initial rainwater using manual operations are prone to failure due to operational problems; the volume of the automatic switch is small, but the structure is complex and the cost is high; in addition, the retention time of initial rainwater is too long, so that solid particle impurities are precipitated, and the device is extremely easy to block and is not beneficial to normal use of the device.

At present, roof rainwater is convenient to collect, however, storage is difficult, rainwater is stored underground and around buildings, and the conditions are not allowed. Because of adopting the downpipe as the water storage equipment, the water storage device does not occupy land, does not influence the appearance and has large water storage capacity. However, there are a number of difficulties, the disposal of the initial rain water and the separation of some solid waste being very troublesome. The volume of the flow discarding device is the volume of all initial rainwater, and the volume is overlarge; some devices that drain initial rainwater using manual operations are prone to failure due to operational problems; the volume of the automatic switch is small, but the structure is complex and the cost is high; in addition, solid matters are easy to enter the container, particularly solid particles exist, and automatic drainage of initial polluted rainwater is difficult.
