摘要:

开展典型规模化蛋鸡场氨气、硫化氢等臭气排放特征研究,对改善鸡舍空气质量、减少家禽养殖污染、控制有害气体排放具有深刻意义。文章对浙江某阶梯式笼养蛋鸡场冬、春、夏鸡舍内外氨气、硫化氢以及臭气浓度进行检测分析,并核算每只蛋鸡的栏舍氨排放速率。结果显示:不同季节鸡舍内NH3平均浓度差异显著,冬季最高(14.46 mg·m-3),仅在冬季鸡舍内检测出H2S气体,蛋鸡舍内不同位置NH3、H2S变化规律在不同季节有所不同,冬季和夏季近入口和排风口位置NH3浓度易受到气流的影响,鸡舍中央区域检测出的NH3、H2S浓度更能代表蛋鸡舍内臭气排放情况;舍外各点位中,除鸡舍出风口NH3浓度在冬季最高外,其余均在夏季最高;冬季和夏季蛋鸡栏舍氨排放速率分别为3.09和18.87 mg·h-1·只-1,夏季栏舍氨排放速率明显大于冬季;对NH3和臭气浓度进行相关性分析,皮尔逊相关系数为0.41,两者相关性较差。

Abstract:

It is of profound significance to carry out research on the emission characteristics of ammonia and hydrogen sulfide in typical large-scale layer farms to improve the air quality of chicken houses, reduce pollution from poultry breeding, and control harmful gas emissions. In this paper, the concentration of ammonia, hydrogen sulfide and odor inside and outside the chicken house in winter, spring and summer of a step cage-rearing layer farm in Zhejiang Province was detected and analyzed, and the ammonia emission rate of each laying hen was calculated. The results showed that the average concentration of NH3 in different seasons was significantly different, the highest was in winter (14.46 mg·m-3), H2S gas was detected only in winter in the chicken house, and the change law of NH3 and H2S in different positions in the chicken house was different in different seasons, and the NH3 concentration near the entrance and exhaust outlet in winter and summer was easily affected by the air flow, and the NH3 and H2S concentrations detected in the central area of the chicken house were more representative of the odor emission in the chicken house. Among the points outside the house, the NH3 concentration was the highest in summer except for the NH3 concentration at the air outlet of the chicken house, which was the highest in winter. The ammonia emission rates of chicken house in winter and summer were 3.09 and 18.87 mg·h-1 per chicken, the ammonia emission rate of the chicken house in summer was significantly greater than that in winter; The correlation analysis between NH3 and odor concentration showed that the Pearson correlation coefficient was 0.41, and the correlation between the two was poor.

Key words: layer, ammonia, hydrogen sulfide, odor concentration, ammonia emission rate, emission rules
