北京某企业生产废水总硬度(以CaCO3计)为533 mg/L,钙硬度(以CaCO3计)为316 mg/L,总碱度为262 mg/L;分别采用石灰-纯碱法和双碱法进行实验,结果表明:在常温下(25℃),采用石灰-纯碱法,石灰投加量为0.55 g/L、纯碱投加量为0.4 g/L时,出水... 北京某企业生产废水总硬度(以CaCO3计)为533 mg/L,钙硬度(以CaCO3计)为316 mg/L,总碱度为262 mg/L;分别采用石灰-纯碱法和双碱法进行实验,结果表明:在常温下(25℃),采用石灰-纯碱法,石灰投加量为0.55 g/L、纯碱投加量为0.4 g/L时,出水效果最佳;采用双碱法,氢氧化钠投加量为0.4 g/L、纯碱投加量为0.06 g/L时,出水效果最佳,两种除硬方法均能达到85%以上的硬度去除率;相比之下,双碱法用药量更低,更具有经济效益。 展开更多
