摘　　要：在贵阳小河污水处理厂的节水改造工程中,采取了以消毒后的出水代替自来水冲洗脱水机滤布、以系统出水代替自来水作为提高滗水器内压用水等节水措施,通过设备改造,减少自来水用量45×104m3/a,减少COD排放量6.75t/a,实现了节能减排的目标。In the water-saving reconstruction project of Xiaohe Wastewater Treatment Plant in Guiyang, the water-saving measures are taken, such as replacing the tap water for washing filter cloth of dewatering machine with disinfected effluent and the tap water for boosting water pressure in decanter with the system effluent. Through equipment reconstruction, the water consumption is reduced by 45 × 10^4 m^3/a, and the emission of COD is decreased by 6.75 t/a, achieving the energy saving and emission reduction.
