    摘要:

    以蔬菜廢棄物與牛糞的混合物為原料，采用好氧發(fā)酵工藝進行發(fā)酵試驗，進行了試驗優(yōu)化設(shè)計，考察了原料配比、曝氣時間和發(fā)酵時間對蔬菜廢棄物固體殘留率的影響，實時監(jiān)測發(fā)酵液的pH值，同時對優(yōu)化設(shè)計后的9個試驗的凱氏氮（TKN）、氨氮（NH+4-N）、硝態(tài)氮（NO-3-N）、亞硝態(tài)氮（NO-2-N）和總磷（TP）進行了測定，考察發(fā)酵液的養(yǎng)分含量。通過對9個試驗的綜合極差分析和主成分分析得到，當(dāng)蔬菜廢棄物和牛糞的質(zhì)量比為3∶1、曝氣時間為2h/d，發(fā)酵時間為40d時可以獲得最佳的發(fā)酵效果。

    Abstract:

    Taking the mixture of vegetable wastes and cow manure as the raw materials and using aerobic fermentation process for fermentation tests, the experiment was conducted and optimized to analyze the effects of the ratio of raw materials, aeration time and fermentation time on the solid residues of vegetables. The pH value of fermentation liquid was real-time monitored and the TKN, NH+4-N, NO-3-N, NO-2-N and TP of 9 treatments were measured after optimized. Then the nutrient contents of fermentation liquid were investigated. Through the comprehensive range analysis and principal components analysis of 9 treatments, the optimal fermentation results were obtained with 3∶1 raw materials (mass ratio), 2 h/d aeration time and 40 d fermentation time.
