【摘要】 油田钻杆刷镀铜废水的铜离子严重超标，为解决这一问题，应用硫化钠（Na2S·9H2O）化学沉淀法处理工艺及设备处理废水。经监测，处理后的废水符合国家排放标准，具有处理设施一次性投资少，操作方便，处理效果好，处理成本适当等优点。硫化钠化学沉淀法处理刷镀铜废水达到了国家排放标准。更多还原

【Abstract】 The copper ion concentration in copper facing water of drilling rod inoil field was heavily over the standard. To solve this problem,the methodology and equipment of chemical precipitation method of sodium sulfide (Na2S·9H2O)treatment hasbeen adopted to treat waste water. The treated waste water is up to the dischargingstandard of the state after monitoring and testing,so that this method has the merits ofless lump-sum investment,operation convenience,better treating effect and suitable processing cost. The chemical precipitation method of sodium sulfide to treat copper facingwater has achieved state’s discharge standard.更多还原
