青藏高原生态大棚的建设与数值仿真

Construction and Simulation of Ecological Greenhouse in Qinghai-Tibet Plateau

首次将污水处理与大棚种植相结合,提出了污水处理回用生态大棚技术,并将其应用于高寒、高海拔地区的生态环保.充分利用了青藏高原充足的太阳辐射资源为生态大棚的正常运行提供能量,并采用ANSYS软件对大棚内的空间温度场进行了不同天气条件下的数值模拟,研究了棚内影响蔬菜生长和污水处理的空间区域内温度变化的规律,从而为合理的大棚结构设计提供了科学依据.模拟结果证明实验所采用的大棚结构具有良好的保温、增温和节能的作用,能够满足高寒、高海拔地区生活污水的处理及蔬菜生长的需要.

The technology of combination of 'sewage water recycling and ecological greenhouse' is firstly put forward, and it is applied to the protection of environment in extremely cold and high elevation area. Moreover, the plentiful solar energy of Qinghai-Tibet Plateau is made full use of to provide the energy for the normal operation of ecological greenhouse. The ANSYS software is applied to analyze the space temperature field in different conditions and study the variant rules of temperature in the main space of growing vegetables and sewage treatment, then a scientific reference to the reasonable construction of the greenhouse is attained. The result of simulation draws the conclusion that the ecological greenhouse plays a good function in raising temperature, keeping temperature and saving energy, so it can meet the need of treatment of sewage water and growing of vegetables.
