Description

Rainwater Ecosystem for Sponge City Residents

technical field

The utility model belongs to the technical field of buildings, in particular to a rainwater ecological system for residents of a sponge city.

Background technique

Sponge city is a new generation of urban stormwater management concept. It refers to the city's good "elasticity" in adapting to environmental changes and responding to natural disasters caused by rainwater. It can also be called "water elastic city". The international general term is "low-impact development stormwater system construction". When it rains, it absorbs, stores, infiltrates, and purifies water, and "releases" the stored water for use 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 acid gases in the air, car exhaust, factory exhaust and other polluting gases, and generally contains a certain amount of toxins that affect plant growth. These toxins may include sulfide, salt, etc., and even inappropriate pH values. After landing on the ground, due to the washing 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 level of the early rainwater is relatively high, usually exceeding that of ordinary urban sewage. degree of pollution. 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. Therefore, the early rainwater must be discarded. It is diverted to the sewage pipeline, and the rainwater with less pollution in the later period of rainfall can be recycled after pretreatment to intercept suspended solids, solid particle impurities, sedimentation, and filtration in the water.

At present, the volume of most waste flow devices is the volume of all initial rainwater, and the volume is too large; some devices that use manual operation to discharge initial rainwater are prone to failure due to operational problems; while the volume that can be automatically switched is small, but the structure is complicated and the cost is high; In addition , The initial rainwater stays for 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. In addition, the water collection tank has only one compartment, which has a single purpose, and some water equipment that requires higher pressure cannot be used directly.

At present, the volume of the discarding flow device is the volume of all the initial rainwater, which 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 is small, the structure is complicated and the cost is high; If the rainwater stays for too long, it will lead to the precipitation of solid particles and impurities, and the device will be easily blocked, which is not conducive to the normal use of the device.
