摘要 调节造纸污泥的水分和C/N比,经过为期50d的交替好氧厌氧堆肥处理,污泥有机质发生降解,TN、TP和TK含量都呈上升趋势,挥发性固体和有机碳分别达到60%和30%的稳定状态,堆肥的种子发芽率达到95%以上,大肠杆菌数低于国家卫生标准,实现造纸污泥无害化、稳定化和减量化的要求。腐熟的污泥堆肥成为高价值的农用产品。 Pulp and paper mill sludge was biosolid waste. The technology of aerobic and anaerobic composting of pulp and paper sludge was studied. The study showed that the organic carbon and the volatile solid decomposed to 30% and 60%; at the same time, the total nitrogen, total phosphorus and total potassium all increased; the cabbage germination index (GI), used as the indicators of phytotoxicity and maturation of the compost, exhibited that the sludge compost was stabilized and mature. 252% GI was obtained after 70 days of composting with adding amendment of cellulosic waste which could promote microbiolactivity and composting process. The germina was almost perished when the coliform group was lower than the national standard at the 70th day. The mature compost could be used as a good safe manure in agriculture.
