通过在不同的温度下,对一种成分复杂的钻井废水进行混凝处理的实验,找出了温度对这类废水处理的影响。温度上升,产生的混凝颗粒尺寸增大,沉降速度加快,但出水的色度指标变差,若要达到低温时的同样效果,必须相应增加处理剂用量。文中也讨论了造成这些现象的原因。 The effect of temperature on the treatment of such wastewaters was investigated by experiments on the coagulation of a complex drilling fluid at different temperatures. As the temperature increases, the size of the coagulated particles increases, the settling velocity increases, but the colorimetric index of the effluent becomes worse. To achieve the same effect at low temperatures, the amount of treating agent must be increased accordingly. The article also discusses the reasons for these phenomena.
