Embodiment 1

[0027] In this example, see figure 1 and figure 2 , a multi-system urban self-circulation system, which is an internal urban circulation system, contains multiple subsystems that can perform material-energy conversion, and realizes sustainable urban operation, including the main body city 1. The urban internal circulation system includes biogas System 2, constructed wetland system 3, rain garden system 4, urban farm system 5 and solar power generation system 6;

[0028] The ontology city 1 is used to realize the basic needs of the residents in the city, and realize sustainable self-circulation operation, which includes input and output of various energies and substances;

[0029] The biogas system 2 is used to degrade the feces and other organic wastes produced in the main city 1 into biogas, carbon dioxide and inorganic nitrogen and phosphorus compounds through microbial degradation;

[0030] The constructed wetland system 3 is used to provide urban clean water, after the ...

Embodiment 2

[0036] This embodiment is basically the same as Embodiment 1, especially in that:

[0037] In this embodiment, the main city 1 is a standard and complete small and medium-sized town area. The downtown area has sound commercial, office, residential, and educational functions, and it is located in a livable environment with sufficient sunlight and rain.

[0038] In this embodiment, the biogas system 2 contains a plurality of energy exchange ports, including a biogas-city exchange port 21 and a biogas-urban farm exchange port 22; the biogas-city exchange port 21 is used for the biogas system of the body city 1 direction 2 transport the generated organic waste, and the biogas system 2 transports the generated biogas and fertilizer to the main city 1; the biogas-urban farm exchange port 22 is used for the biogas system to transport the generated fertilizer to the urban farm system.

[0039] In this embodiment, the constructed wetland system 3 includes a plurality of energy exchange...

Embodiment 3

[0045] This embodiment is basically the same as the above-mentioned embodiment, and the special features are:

[0046] In this example, see figure 1 , this embodiment is an energy-waste urban self-circulation system, which is a sustainable system from the city, including the input and output of various energy forms, and is characterized in that many subsystems use the waste produced by the city and their own attributes , to generate the energy needed for the continuous operation of the city, making it called renewable energy, and there are interfaces between each system and the city, see figure 2 .

[0047] See attached figure 2 , the present embodiment has the design of a multi-system urban self-circulation system, which is an internal circulation system of the city and contains a plurality of subsystems capable of material-energy conversion, with the purpose of realizing sustainable urban operation. It is characterized in that, Including the main body city, biogas syste...

Abstract

The invention discloses a multi-system city self-circulation system. The system is a city internal circulation system, comprises a plurality of subsystems capable of performing substance-energy conversion, realizes sustainable operation of a city including a main body city. The city internal circulation system comprises a biogas system, an artificial wetland system, a rainwater garden system, a city farm system and a solar power generation system. The multiple substance-energy subsystems are combined with the urban system, waste, waste water and the like are input into the subsystems from the city, after the subsystems work, energy and clean water for the city are generated, and sustainable operation of the city is achieved, namely improvement of city self-circulation design is achieved. According to the self-circulation system of the invention, the problems of high pollution rate and low waste utilization rate in small and medium-sized cities and towns are solved, and sustainable self-circulation operation in cities without the help of external input can be realized in the improved system.

Description

technical field [0001] The invention relates to the field of urban sustainable self-circulation design, in particular to a multi-system urban self-circulation system capable of maintaining urban low-carbon environmental protection, self-sufficiency and sustainable operation. Background technique [0002] Today, the contradiction between energy and waste in cities is becoming more and more prominent, especially in some small and medium-sized towns around the world. Cities emit large amounts of waste into the natural environment and consume more energy in the process of producing the energy that cities need. Landfills cause a lot of soil pollution; the construction of sewage treatment plants requires a lot of resources, and the operation requires continuous energy input; the traditional power generation model consumes non-renewable fossil fuels, and a large part of the converted energy Instead, it directly becomes waste that causes air pollution. Addressing the lack of energ...
