Construction of resource utilization engineering mode for agricultural residues

Abstract: As the key issue of agro-environment protecting facility engineering, the resource utilization engineering of agricultural residues is becoming more and more important in the process of establishing circular agriculture and ecological civilization. The resource utilization of agricultural residues refers to lots of aspects such as its technology, organization, engineering and policy and so on. Currently, domestic researches most focus on the status quo, technology exploration and evaluation of resource utilization. As the comprehensive study of resource utilization, the ways to use the resource is more regarded. However, the research on mode construction of resource utilization for agricultural residues is still lacking. Therefore, it is necessary to form corresponding modes with regional adaptability. The mode construction of resource utilization for agricultural residues using scientific and reasonable method can provide theoretic support for the development of agro-environment protecting facility. 　　The primary goal of mode construction is handling the agricultural residues in order to solve the problem of environmental pollution. In addition, the mode construction can help to obtain some economic benefits. A systematic methodology was used in this research. On the basis of the theory of industrial development, system and circular economy, this paper obtained a constructing method of integrated mode considering regional adaptability which concludes the construction of technology mode, organization mode and industry mode. Determination of the three modes is not only a relatively independent process, but also an inextricably linked and spiraling process. Then, the coupling of above three modes contributes to the construction of integrated mode with good balance and running effect. In the process of mode construction, external influencing factors and internal components were taken account thoroughly. The external influencing factors consists of the agricultural residue amounts, the technology adaptability, agricultural mode, the economy state, policy conditions and development plan, etc. The internal components include operating subjects, key technology, organization pattern and industrial layout. The final integrated mode reflects the technical, economic and social development needs and includes the specific technology composition, organization pattern, and certain industrial scale. The process of proposing the constructing method of the resource utilization mode is also the process of systematic analysis of the external and internal factors that affect agricultural residues utilization. In the process of actually building the mode, influential factors could be considered as important evaluation indexes of mode selection, components could be considered as the main body of mode construction. It makes the mode construction of agricultural residues recycling project more specific and practical. In the meantime, this method can also apply to agricultural waste water treatment projects and other environmental protection fields of agricultural producing area.
