| 摘 要： | 为提高原水的pH值,强化混凝、沉淀效果,优化出水水质,在给水处理过程中需投加碱性调节剂。研究对比了食品级氢氧化钠和碳酸钠调节pH值的效果,以及对出水水质的影响。分析了2种碱性调节剂的投加成本,结果表明,采用食品级固体氢氧化钠作为碱性调节剂时效果良好,生产成本更低。

| Abstract: | In order to increase the pH value of the raw water,strengthen the coagulation and sedimentation effect,improve the effluent water quality,alkalinity regulator should be added during the water supply treatment.The adjusting effects of food-grade NaOH and Na2CO3 to pH value,and the influences of them on effluent water quality were compared and studied.Furthermore,the costs of the said two alkalinity regulators were analyzed,and the results indicated that,using food-grade solid NaOH as the alkalinity for water supply treatment could obtain a good effect and the production cost was lower. |
