Abstract

The invention provides an energy utilization system of organic wastes with zero emission of carbon dioxide, which organically combines anaerobic fermentation hydrogen production, methane fermentation, CO2 absorption, microalgae fixation CO2, biogas liquid treatment and energy grass planting. The system is suitable for treating various types of organic wastes, can be applied to the treatment of agricultural organic wastes, industrial organic wastes, domestic organic wastes, slurry and the like, and the industries, such as new energy development. Through the application of the invention, the specific application demonstration of recycling economy can be carried out, clean energy is obtained while eliminating environmental pollution, no greenhouse gas emits in the process, and the triple effects of wastes treatment, production of clean and renewable energy sources and reduction of carbon dioxide emission can be realized.

Description

technical field [0001] The invention belongs to the fields of waste treatment and clean energy development, and in particular relates to a carbon dioxide emission-free organic waste energy utilization system. technical background [0002] It is an indisputable fact that the excessive development and utilization of fossil fuels has caused global warming, acid rain, and ecological environment damage and degradation, and fossil fuels are also facing exhaustion. Therefore, based on environmental and energy considerations, human beings urgently need a non-polluting of renewable energy. Hydrogen energy is an ideal clean and renewable alternative fuel. It only produces water after burning, without other greenhouse gases, and can be directly and efficiently converted into electricity through fuel cells. From an environmental point of view, the use of various organic wastes for anaerobic fermentation of hydrogen production is a major research focus in recent years, and is considered...
