摘要: 以优化好氧发酵高温阶段工艺为目的,采用鸡粪和玉米秸秆为原料,选取高温阶段温度、时间、菌剂添加量为工艺参数进行单因素试验和正交试验,以酸碱度(pH)、电导率(EC)、碳氮比(C/N)和种子发芽指数为评价指标,对农业废弃物高温好氧发酵中高温阶段工艺开展研究。结果表明,高温阶段最佳工艺条件为菌剂添加量20 g/kg、温度75 ℃、发酵时间12 h。

Abstract: In order to optimize the process of the high temperature stage of aerobic fermentation, chicken manure and corn straw were used as raw materials. The single factor test and orthogonal test were carried out by selecting the temperature, time and dosage of the microbial agent in the high temperature stage as the process parameters. The pH, conductivity(EC), the ratio of carbon to nitrogen(C/N) and seed germination index were used as evaluation indexes to study the high temperature stage process of high temperature aerobic fermentation of agricultural waste. The results showed that the optimum technological conditions in the high temperature stage were as follows: the addition amount of the microbial agent was 20 g/kg, the temperature was 75 ℃, and the fermentation time was 12 h.

Key words: agricultural waste, livestock manure, corn straw, high-temperature stage of aerobic fermentation, process optimization
