    摘要:

    研究了冷,、暖季節(jié)下生物發(fā)酵床、水泥實心,、全縫隙3種不同地面結(jié)構(gòu)的機(jī)械通風(fēng)育肥豬舍的惡臭濃度,、排放系數(shù)及地面結(jié)構(gòu)、舍內(nèi)溫濕度,、豬體重對惡臭濃度的影響。研究表明：豬舍的惡臭濃度與舍內(nèi)溫度,、豬體重呈顯著正相關(guān)(p<0.05),，惡臭濃度與相對濕度無顯著相關(guān)性（p>0.1）；地面結(jié)構(gòu)不同,，惡臭濃度存在顯著差異（p<0.05）,；生物發(fā)酵床豬舍有助于惡臭減排，惡臭濃度最低,，水泥實心地面豬舍的惡臭濃度最高,，全縫隙地面豬舍的惡臭濃度居中；生物發(fā)酵床,、全縫隙,、水泥實心地面育肥豬舍的惡臭排放系數(shù)分別為（3.39±3.33）、（3.70±1.31）,、（4.33±2.39）OU/(m2·s),。

    Abstract:

    Odor samples from three fattening rooms with different floor systems were collected and analyzed by using triangle odor bag method under cool and warm weather. It showed that there were significantly positive correlations between odor concentration and indoor temperature and pig weight（p<0.05）. The correlation was not significant between odor concentration and relative humidity（p>0.1）. Significant differences were found in the three pig rooms with different floor systems（p<0.05）. Odor concentration was highest in the pig room with traditional concrete floor system; full-slatted floor system was the second, and the lowest for deep-litter fermentation system. The results indicated that deep-litter system was effective for odor mitigation. Odor emission factors from the deep-litter room, fully-slatted floor room, and concrete floor room were (3.39±3.33), (3.70±1.31) and (4.33±2.39)OU/ (m2·s), respectively. 
