Description

A rainwater collection and ecological utilization system for buildings

technical field

The utility model belongs to the technical field of rainwater reuse, in particular to a rainwater collection and ecological utilization system for buildings.

Background technique

Sponge city is a new generation of urban stormwater management concept, which means that the city has good "elasticity" in adapting to environmental changes and responding to natural disasters caused by rainwater, and can also be called "water elastic city". The international term is "low-impact development stormwater system construction". When it rains, it absorbs, stores, seeps, and purifies water, and “releases” the stored water and makes use of it when needed.

During the initial rainfall, the first 2~5mm of rainwater is generally seriously polluted and the flow rate is relatively small. Rainwater dissolves a large amount of acidic gases, car exhaust, factory exhaust and other polluting gases in the air, and generally contains a certain amount of toxins that affect plant growth. These toxins may include sulfides, salts, etc., and even inappropriate pH values. After landing on the ground, due to the scouring of the asphalt linoleum roof, etc., the early rainwater contains a large amount of pollutants such as organic matter, pathogens, heavy metals, grease, suspended solids, etc. Therefore, the pollution degree of the early rainwater is relatively high, usually exceeding the level of ordinary urban sewage. degree of contamination. If the early rainwater is directly discharged into the natural receiving water body, it will cause very serious pollution to the water body, and the rainwater cannot be directly recycled, so the early rainwater must be discarded. Diverted to the sewage pipeline, the rainwater with less pollution in the later period of rainfall can reach the standard of recycling after pretreatment to intercept suspended solids, solid particle impurities, sedimentation and filtration.

At present, the volume of most of the discarding devices is the volume of all the initial rainwater, and the volume is too large; some devices that use manual operation to discharge the initial rainwater are prone to failure due to operational problems; and the volume that can be automatically switched is small, but the structure is complex and the cost is high; , the initial rainwater stays too long, resulting in the precipitation of solid particles and impurities, and the device is easily blocked, which is not conducive to the normal use of the device.

At present, the collection of rainwater on the roof is convenient, but it is difficult to store it. It is often not allowed to store rainwater underground and around buildings. Because the downpipe is used as the water storage device, it does not occupy land, does not affect the appearance, and has a large water storage capacity. However, there are also a series of problems. The treatment of initial rainwater and the separation of some solid wastes are very difficult problems. The volume of the discarding device is the volume of all the initial rainwater, and the volume is too large; some devices that use manual operation to discharge the initial rainwater are prone to failure due to operational problems; although the volume that can be automatically switched on and off is small, the structure is complex and the cost is high; Into the container, especially with solid particles, it is very difficult to pollute the rainwater in the initial stage of automatic disposal.
