摘　　要：将废弃食用菌栽培料(SMC)首次应用于好氧反硝化脱氮中,考察了SMC投加量、初始亚硝氮浓度、温度、初始pH值和转速对好氧反硝化脱氮率的影响。结果表明,在SMC投加量为4%、温度为30℃、初始pH值为7、转速为180r·min^(-1)的条件下,初始浓度为40mg·L^(-1)的亚硝氮在78h内被完全去除,脱氮率达100%。表明,SMC具有应用于好氧反硝化脱氮的潜力,也为"以废治废"的循环经济路线提供了新思路。The spent mushroom compost（SMC）was employed in aerobic denitrification for the first time.The effects of SMC dosage,initial concentration of nitrite nitrogen,temperature,initial pH value and rotational speed on nitrogen removal rate were investigated.Results showed that,under the conditions as：SMC dosage of4%,temperature of 30 ℃,initial pH value of 7and rotational speed of 180r·min^（-1）,40mg·L^（-1） nitrite nitrogen was completely removed with 100% of nitrogen removal rate,which indicated that SMC had potential to be applied in aerobic denitrification and provided a new idea for circular economy of using waste to treat waste.
