| 摘 要： | 对流动电流(SC)混凝投药控制技术应用于受含油废水污染的水中进行了试验,研究了污染物对流动电流响应混凝剂投量的变化规律、流动电流检测灵敏度、以及控制系统的给定值的影响,初步探讨了流动电流混凝投药控制系统在受污染水源水中的适用性问题.研究结果发现有机污染物的存在使流动电流的响应强度降低,流动电流检测灵敏度下降,控制系统给定值有所升高,其影响程度与污染物的种类、浓度等因素有关.但是在受污染水源中流动电流与投药量的相关性仍然存在,一般地,油类物质含量不超过2～10 mg/L(视油类物质颗粒尺寸)的水源水中,污染物对流动电流控制系统影响较小,流动电流混凝投药控制技术仍然可以应用于此条件下的受污染水源水.

| Abstract: | An experimental study was carried out through two kinds of water that were polluted by different oil pollutants. The effect of the regularity, precision and the set point of streaming current control system by the oil pollutant were studied. The relationship between streaming current(SC) and coagulant dosage was still existed under the experimental condition. However the pollutant in the water affected the regularity of streaming current control system, decreased the precision of streaming current control system, and made the set point rise. Moreover, the kinds of the pollutant and the concentration of the pollutant were key factors. The function of the oil pollutant can be neglected when its concentration does not exceed 2-10mg/L. Therefore, the streaming current control methodfor coagulant dosage can be used in the water resource that is polluted by oil-pollutant under the experimental condition. |
