- 摘要：通过对某公司工业水车间混合污泥及浮渣在不同配比条件下PAM的加入量进行考察，得出结论：针对混合污泥，其阳离子PAM最佳加剂浓度为100 mg/L，此时絮凝效果好，上清液干净，浊度值为9.52 NTU；当混合污泥与浮渣进行配比，浮渣含量在10%~40%时，阳离子PAM药剂添加浓度控制在100~380 mg/L，絮凝效果较好；当混合污泥与浮渣配比，浮渣含量在50%以上时，阳离子PAM药剂添加浓度>500 mg/L，絮凝效果不理想，处理成本较高。此实验可以为三泥干化过程中优化药剂投加量提供技术支持。Abstract: After investigating the PAM addition to mixed sludge and dross in a company's industrial water workshop under differentratio conditions, it drawn a conclusion that, for mixed sludge, the optimal concentration of cationic PAM was 100 mg/L, it wouldshow good flocculation effect, cleansupernatant, and the turbidity value to 9.52 NTU. When the mixing sludge and drosswereproportioned and the dross content was 10%~40%, the addition concentration of cationic PAM was controlled within 100~380 mg/L,then the flocculation effect was better. When the proportion of mixed sludge and drosswas more than 50%, the concentration ofcationic PAM was more than 500 mg/L, the flocculation effect was not ideal with highertreatment cost.This experiment could providetechnical support for optimizing the dosage of chemical agent in the drying process.
