    针对严寒地区气温低、污水厂曝气池工作温度低的问题, 利用仿真模拟分析大棚内空气温度分布及流动特性, 对严寒地区冬季低温条件下污水厂利用大棚保温技术进行研究。结果表明:在冬季室外温度-22℃条件下, 通过外扣大棚对曝气池保温, 棚内空气平均温度达到4.0℃左右, 曝气池出口水温达到11.2℃左右;曝气池外棚保温膜材料以PO 材料保温效果最优, PVC 材料最不可取, PE 和EVA 材料居中;曝气池选用2.5 m 棚拱高度的外扣大棚保温效果较好;双层保温膜保温效果优于单层保温膜。

    For the problem of low temperature in cold regions and low working temperature in aeration tanks in sewage works, the heat preservation technology in greenhouses of wastewater works is studied by means of simulation to analyze the temperature distribution and air flowing features in greenhouses. Results show that under the condition of -22℃ outdoors in winter, through the insulation of the canopy towards the aeration tank, the average air temperature remains at 4℃ or so, while the water temperature of the outlet of the aeration tank remains at about 11.2℃; The optimal material of insulation membrane of the outside aeration tank is PO, while the most undesirable material is PVC, And PE and EVA are mediate; and the aeration tank of the best heat preservation is the one that uses greenhouse of 2.5 meter height. The effect of double insulation membranes is better than that of a single membrane.
