Biomass cyclic planting system on roof

Abstract

The invention provides a biomass cyclic utilization method. Ecosystems are built on a roof and the equipment is formed by connecting a main cistern, a water supply pipe, planting devices, an aquarium, a fermenter, an earthworm culture case and an auxiliary cistern in order and forms a cyclic system of water and biomasses, wherein water automatically flows to the auxiliary cistern from the main cistern after passing through the planting devices and then is conveyed to the main cistern by a water pump. The method has the following beneficial effects that water cycle ensures stable water-bearing layers and breathable layers to exist at the bottom of the soil for culture in the planting devices; after undergoing twice fermentation treatment, the kitchen wastes enter the selenium-bearing soil for culture; the green plants produce new biomasses, wherein the inedible parts are re-degraded into plant nutrients and the edible parts have health care function, thus ensuring urban greening to produce direct economic benefits and saving social resources; and through continuous cycle of the water and biomasses, the whole system can continuously absorb carbon dioxide, release oxygen, provide high-quality food, treat kitchen wastes and reduce the roof temperature and has the function of protecting the building.

Description

technical field [0001] The invention relates to a method for recycling biomass. Kitchen waste organic waste is processed into organic fertilizer, which is placed in a planting device to cultivate green plants, and can realize automatic water supply, which can ensure the transpiration and photosynthesis of green plants. needed moisture. It is suitable for garbage sorting and greening of roof balconies in areas such as roofs, communities and courtyards, especially for building rooftop farms. Background technique [0002] Now, with the development of urbanization, there is less and less agricultural land, more and more urban garbage, garbage siege, heat island effect, sharp decline of cultivated land, food safety and other issues are affecting the lives of urban residents. [0003] People depend on food, and urban residents consume a lot of food every day. Most of these foods are imported from other places. Long-distance transportation requires energy consumption, which is not...

Problems solved by technology

[0006] At present, the domestic waste of urban residents is not classified and recycled, and all kinds of waste are incinerated or landfilled in the waste disposal site, which will have an adverse impact on the environment. At the same time, it will consume a lot of manpower, material and financial resources; existing urban roof greening The cost of establishment and maintenance is very high. At the same time, green plants cannot absorb as much underground water vapor as plants on the ground (commonly known as "ground gas"), and cannot guarantee the water required for transpiration and photosynthesis. Green plants cannot Play its due ecological role of lowering the temperature, absorbing carbon dioxide and releasing oxygen
