Abstract

The invention discloses a sewage circulation green building, which comprises a soil layer arranged on the roof of the building for planting plants, a primary water tank and a secondary water tank are arranged side by side under the soil layer, and the tap water of the tap water system enters the primary water tank through a water pump. As domestic water or fire-fighting water, the sewage generated after the tap water in the primary water tank is used enters the sewage tank through the first sewage standpipe, and is irrigated on the soil layer of the roof of the building through the circulation pipe under the action of the circulating pump; rainwater or The excess water in the soil layer enters the secondary water tank through the filter and is used as water for flushing the toilet. After being used as water for flushing the toilet, the sewage generated by the toilet enters the septic tank through the second sewage standpipe, and after passing through for a period of time , under the action of the delivery pump, it is transported by the delivery pipe to the soil layer on the roof of the building, as a fertilizer for plants. The invention can utilize the roof space for greening and effectively treat domestic garbage generated in the building, and has low cost and wide application.

Description

A sewage recycling green building

technical field

The invention relates to building construction, in particular to a sewage recycling green building.

Background technique

At present, with the development of urbanization, there are more and more buildings. The increase of buildings, on the one hand, squeezes and occupies a large amount of land and green space, and on the other hand, the domestic garbage generated in the buildings is increasing day by day, which brings great difficulties to garbage disposal.

However, with the increase of buildings, the roof area of the city is getting bigger and bigger. Roof greening (including planting crops, vegetables, fruits, etc.) can improve the appearance of the urban environment, improve the quality of citizens' living and working environments, alleviate atmospheric dust, purify the air, protect the top of buildings, prolong the service life of roof building materials, alleviate the urban heat island effect, and keep warm Heat insulation, reduce the use of air conditioners, save energy, reduce urban noise, increase air humidity, purify water sources, and improve land resource utilization; at the same time, domestic garbage generated in buildings can also be recycled through roof greening to solve the problem of garbage disposal .

Contents of the invention

The purpose of the present invention is to provide a green building with sewage circulation, which can use the roof space for greening and effectively treat domestic garbage generated in the building, with low cost and wide application.

To achieve the above object, the present invention can take the following technical solutions:

A sewage circulation green building of the present invention comprises a soil layer arranged on the roof of the building for planting plants, a primary water tank and a secondary water tank are arranged side by side under the soil layer, and the tap water of the tap water system enters the primary water tank through a water pump. The water tank is used as domestic water or fire-fighting water. The sewage generated after the tap water in the primary water tank is used as domestic water enters the sewage pool through the first sewage standpipe, and is irrigated on the roof of the building through the circulation pipe under the action of the circulation pump. The soil layer; rainwater or excess water from the soil layer enters the secondary water tank through the filter and is used as water for flushing the toilet. After being used as water for flushing the toilet, the sewage generated by the toilet enters the septic tank through the second sewage standpipe After a certain period of time, the pool is transported to the soil layer on the roof of the building by the transport pump under the action of the transport pump, as a fertilizer for plants.

There is also a kitchen waste crushing and fermentation tank, and the kitchen waste in the building enters the kitchen waste crushing and fermentation tank through the third riser, and is sent to the soil layer on the roof of the building by the hoist as a soil supplement.

There are fire-fighting platforms around the roof of the building, and the water in the primary water tank and the secondary water tank is used for fire-fighting in case of fire.

There is an elevator on one side of the building, which is used to carry small agricultural machinery to the roof of the building.

Compared with the prior art, the beneficial effects of the present invention are: due to the adoption of the above-mentioned technical scheme, a primary water tank and a secondary water tank are arranged side by side under the soil layer on the roof of the building, and the tap water of the tap water system enters the primary water tank through the water pump. The water tank is used as domestic water or fire-fighting water. The sewage generated after the tap water in the primary water tank is used as domestic water enters the sewage pool through the first sewage standpipe, and is irrigated on the roof of the building through the circulation pipe under the action of the circulation pump. The soil layer; rainwater or excess water from the soil layer enters the secondary water tank through the filter and is used as water for flushing the toilet. After being used as water for flushing the toilet, the sewage generated by the toilet enters the septic tank through the second sewage standpipe After a certain period of time, the pool is transported to the soil layer on the roof of the building by the delivery pipe under the action of the delivery pump, as a fertilizer for plants. This structure makes full use of the roof space to plant plants (such as rice, fruits or trees) for Greening effectively utilizes rainwater and excess water in the soil layer to flush the urinal, and recycles domestic sewage and urinal sewage separately, achieving the effects of saving land, recycling water, and reducing sewage discharge in buildings.

Further beneficial effect: since there is also a kitchen waste crushing fermentation tank, the kitchen waste in the building enters the kitchen waste crushing fermentation tank through the third standpipe, and the hoist is sent to the soil layer on the roof of the building as a soil supplement , this structure further reduces the discharge of sewage in the building and supplements the soil quality and nutrients of the soil layer. The fire-fighting platform is arranged around the roof of the building, which is convenient for fire-fighting. The water in the primary water tank and the secondary water tank can be used to extinguish the fire because it is located on the roof of the building.
