| 摘 要： | 中小造纸厂废水处理常用PAC作混凝剂 ,PAM作助凝剂。由于PAM成本很高 ,影响了处理设备的投运率。用超细滑石粉 (SFT)替代PAM助凝 ,与混凝剂PAC配合 ,其混凝处理效果基本相当 ,但是处理成本降低 0 .10元 /m3 。由于SFT属环境无害材料 ,不会给排泥带来二次污染

| Abstract: | The wastewater from medium-sized and small-sized papermaking plants is often treated with PAC coagulant and PAM flocculant.The high cost of PAM affects the operational percentage of treating equipments.if SFT is used as a substitute for PAM,when it is used with PAC coagulant together,the result of flocculation will be equal,but the treating cost will be decreased by $0.10 yuan/m 3. For SFT is a kind of environment-friendly material, it won't pollute sludge the second time. |
