佛山市龙江镇污水处理厂节能改造

Energy Saving Reform of Longjiang Sewage Treatment Plant in Foshan City

根据佛山市龙江镇污水处理厂工艺及设备的特点,调查分析了该厂的实际运行状况、能耗构成及能耗损失的环节和原因。通过对空气悬浮鼓风机的应用,优化曝气控制系统,对污水提升泵和污泥回流泵实施变频改造以及厂区节能改造,每年可节约90.91×10~4kW·h的电量,降低生产成本61.98万元。

According to the characteristics of the process and equipment of Longjiang Sewage Treatment Plant in Foshan, the actual operating conditions of the process were investigated, and the energy consumption composition and the reasons of energy loss were analyzed. Through some measures of the application of turbo blower, optimization of aeration system, frequency conversion reform of the sewage lift pump and the sludge reflux pump as well as energy saving reform in plant area, the power consumption of 90.91 × 104 kW · h can be saved annually, and the production cost of 619 800 yuan can be reduced.
