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.

Through an innovative engineering design, our research enabled us to grow several kinds of aquatic animals and plants in an automatically controlled ecological greenhouse in a high density, intensive and water-saving manner.

Considering the characteristics of the domestic sewage at the medium-small Qinghai-Tibet railway stations,the ecological greenhouse is adopted,which forms a small artificial semi-closed environment at the bad natural condition of Qinghai-Tibet plateau so as to provide dynamic heat balance and the cyclic balance of O2-CO2 for sewage biological treatment.

This paper introduces the early-stage preparation, matters need attention, pouting, maintenance and form removal of concrete construction in winter, and expounds the technical measures and construction scheme of warm shed conservation, and sums up the construction scheme in winter under the conditions of tighter construction period and lower temperature.
