Background technique

With the rapid development of urban construction, people pay more and more attention to the construction of communities, but people often focus on the construction of intelligent communities with convenient life, while ignoring the construction of energy-saving systems, such as community water-saving systems. At present, the water consumption of urban toilets is as high as more than 30%. In addition, the water consumption of greening caused by the construction of green communities is also high. For example, our domestic wastewater can be used for toilets and greening after simple filtration, which can respond to the country's "strengthening" Conservation and protection, to achieve the sustainable use of water resources" call.

Therefore, in order to realize the development and construction of the community water-saving system, it is necessary to comprehensively consider the water system of the entire community, and design a community water-saving system that recycles domestic wastewater.

Detailed ways

Example:

As shown in FIG. 1 , a water-saving system for recirculating domestic wastewater in a residential area according to the present invention mainly includes a domestic wastewater collection system, a filtration storage system, an indoor recycling system for recycled water, and an outdoor recycling system for recycled water. Taking the first unit building as an example,

The domestic wastewater collection system is mainly composed of the first unit building recycled water main pipe 17 and the first indoor recycled water branch pipe 15. The recycled water branch pipes in each room in the first unit building are respectively connected with the first unit building recycled water main pipe 17. Recovery water branch pipe 15 links to each other with indoor mop pond drainpipe 7, bath drainpipe 8, washing machine drainpipe 9, washbasin 10 for washing hands, dishwashing basin 11 and water purifier waste water pipe 12 successively.

The filter storage system is composed of a filter 6, a community recycled water storage tank 5 and a community waste water pipe 19. The recycled water main pipes of each unit building are connected to the filter 6, and the clean water after the filter is transported to the community recovered water storage tank 5, and The sewage is transported to the waste water pipe 19 of the residential area. Filters 6 are arranged between the main water recovery directors of each unit building and the recovery water storage tanks in the community 5, which can realize the filtration and purification of domestic waste water and improve the water quality of recycled water, that is, the recovery water of the first unit building can be treated by the filter 6. The domestic wastewater in the supervisor 17 is simply purified, and the purified clean water is stored in the community recovery water storage tank 5, so that the subsequent indoor toilet 14, outdoor community greening field 4 and community free car wash 1 can be used to prevent domestic wastewater from Dirt blocks the toilet 14, pollutes the greenery in the greening field 4 of the residential area, and wears the vehicle in the free car wash 1 of the residential area; and the purified sewage is transported to the waste water pipe 19 of the residential area and discharged.

The recycled water indoor reuse system is mainly composed of an additional pump 20, an indoor recycled water pipe 13 and a toilet 14. One end of the indoor recycled water pipe 13 is connected to the community recycled water storage tank 5 through the increased pump 20, and the other end is connected to the toilet 14 in each room;

The recycled water outdoor reuse system is mainly composed of an additional pump 20, an outdoor recycled water pipe 3, a water-absorbing green area 2, a free car wash in the community 1 and a green area 4 in the community. The outdoor recycling water pipe 3 is introduced into the water-absorbing green space 2 . The water-absorbing green space 2 is provided with a community greening field 4 and a community free car wash 1. This design realizes the replenishment of groundwater sources, that is, green water and car washing water can penetrate into the ground through the water-absorbing green space 2, which can not only replenish groundwater, but also promote recycling. Reuse of water resources and protection of ecological environment.

An additional pump 20 is provided between the community recovery water storage tank 5, the indoor recovery water pipe 13, and the outdoor recovery water pipe 3, so that the clean water in the community recovery water storage tank 5 is transported to the indoor recovery water pipe 13 and the outdoor area by pressurization and against gravity. Recycle the water pipe 3 to ensure the use of the follow-up toilet 14, the greening field 4 of the community and the free car wash 1 of the community.

The purified recycled water is used for the indoor toilet 14, the outdoor green area 4 and the community free car wash 1. This design can not only realize the reuse of recycled water, but also reduce the living cost of residents. The recycled water to be purified Transport to the toilet 14 in each room through the indoor recycling water pipe 13 for free use by the residents, and transport to the community greening field 4 and the free car wash 1 in the community through the outdoor recycling water pipe 3 for greening and free self-service car washing water in the community. Recycled water can be used instead of domestic water to save water, and it can be used for free to reduce living costs.
