Problems solved by technology

[0005] The landscape water body of the community can not only properly adjust the climate of the community, but also provide people with a pleasant place for body and mind. However, if the water cannot be replenished normally, the proper landscape effect will not be achieved, and it may become an idle decoration, causing huge waste. At the same time, it will also affect the mood of residents

example 1

[0017] A typical residential building in a residential area in Xuzhou City covers an area of ​​985m2. There are 56 households and 120 people in four units on the 7th floor. The green space behind the building is 1265m2. According to calculations, each household in the building uses an average of about 500 liters of water per day, and the 28 households discharge a total of 700 liters of washing water per day.

[0018] After negotiating with the residents of the building, the drainage renovation of the building was carried out. Through the renovation of the washing basin and the washing drainage system, the relatively clean water discharged from the washing basin was connected to the rainwater pipe through a special pipe, and a 3×3×0.8 building was built under the outlet of the rainwater pipe. m filter.

[0019] The filter tank is 0.2m high to ensure that the washing water does not flow out; the upper filter material is 0.4m thick, which is a 1:1 mixture of river sand and local ...

[0022] A college of a university in Jiangsu Province covers an area of ​​4450m2, surrounded by green areas of 3894m2, the number of people who usually use water is about 340, the water quota is 2.5m3 / (person.month), and the reuse coefficient is 0.5. Then 14m3 of clean sewage can be collected every day.

[0023] After the renovation of the washing basin and the washing and drainage system, the drainage of the college building was reconstructed, and the clean water discharged from the washing basin was connected to the rainwater pipe through a special pipe, and a 9×2×0.8m filter was built near the outlet of the rainwater pipe.

[0024] The filter tank is 0.2m high to ensure that the washing water does not flow out; the upper filter material is 0.4m thick, which is a mixture of local surface soil, coarse sand and zeolite at a ratio of 1:1:0.025; the middle layer filter material is river sand with a thickness of 0.1m; It is a pebble with a particle diameter of around 0.1m. The up...

Abstract

The invention discloses a building rainwater and washing water collection and reuse system used for community greenbelt irrigation and landscape water supplement systems. The system comprises a rainwater drainage port, a rainwater drainage pipe, a double water drainage and washing basin, a fast filtering pond and a water collecting pond. The rainwater drainage port is arranged according to building top platform area size and washing water collection convenience situation, and the lower end of the rainwater drainage port is connected to the rainwater pipe; a sewage drainage pipe and a clean water drainage pipe are arranged below the double water drainage and washing basin and are provided with valves, and the lower end of the clean water drainage pipe is connected to a building rainwater drainage pipe. The collected rainwater and the washing clean water (washing vegetables and fruits) flows into the filtering pond with multiple layers of fillers, is stored in the water collecting pond after simple treatment and is used for community greenbelt irrigation, and the residual water is collected through an overflow groove and is used for supplementing community landscape water or underground water. Thus, living water can be saved, greenbelt irrigation water can be supplied, and the load of downstream sewage treatment plants can be reduced.

Description

Technical field: [0001] The invention relates to a building rainwater and washing water collection and reuse system Background technique: [0002] Buildings such as residential quarters or office buildings of enterprises and institutions consume a lot of washing water, and the water quality is relatively clean. At present, this kind of water is directly discharged from sewage pipes, which not only causes waste of water resources, but also increases the load of downstream sewage treatment plants. Though there are similar double drainage washbasins, their cleaning water is collected and limited to indoor use, thereby greatly limiting its use. [0003] Usually buildings use rainwater drainage pipes to collect roof rainwater and discharge it outside. Generally, newly-built residential areas adopt the rainwater and sewage diversion system, but the diverted rainwater directly enters the surface water body, which only reduces the load of the downstream sewage treatment plant, and...
