摘要
烟厂废水污泥含有大量的高浓度生物碱、酚类、醇类、白胶、香精香料、机油等难降解处理有机物,气味恶臭。本文采用压滤实验,从进泥量、加药量、搅拌机转速三个方面对带式压滤机性能参数的优化进行了实验分析。综合脱水效果和经济因素,最佳压滤脱水条件为:进泥量3 m3/h;加药量75L/min(3.0kg/t干污泥);搅拌机转速70r/min。
Cigarette factory wastewater sludge contains a lot of high levels of alkaloids, phenols, alcohols, white glue, flavor spices, oil andso on thatdealing withdifficult degradate.The smellof thesludgeis stenchandit is urgentlyneed to besolved.Based on filter-pressingtest, theamount of sludgeintofilter press, flocculant dosage and stirrerspeedwerestudied. Takingbothofdewatering effectandcost-effectiveness intoaccount,the optimum volumeof sludge were 3m3/h; PAM dosage were 75L/min(3.0kg/t dry sludge); stirrer speed were 70r/min.
