【摘要】 为了解我国中部某农业大市小规模畜禽养殖污染及治理现状,总结和借鉴其养殖污染防治经验,探索我国小规模畜禽养殖污染防治的可行道路,采取全面调查的方式重点了解该市小规模畜禽养殖场的养殖规模、养殖模式、粪便处理方式等基本情况。结果表明:该市小规模畜禽养殖基数庞大,年排放COD和氨氮总量分别可达71 784.55t和6 591.75t,且养殖场普遍存在选址布局不合理的问题。建议可根据各地实际情况,科学规划种养业布局和规模,大力推行生态种养结合模式、零排放养殖技术、废物资源化利用技术等,逐步实现清洁养殖。更多还原

【Abstract】 The present study aimed at investigating small-scaled livestock and poultry breeding farms of a city in central China. Based on the pollution and treatment status of these farms and the relevant advanced experience in controlling pollution,the paper explored a practical way for controlling pollution of small-scaled livestock and poultry breeding farms in China. The basic information such as breeding scale,breeding model and manure disposal of these farms were investigated in present study. The results showed total emission amount of COD and ammonia nitrogen of all small-scale livestock and poultry breeding farms was 71 784. 55 and 6 591. 75 t / a respectively,and the location and layout of these farms was generally not scientific. Based on the factual situations,it is recommended that the planting-breeding combined pattern,zero-emission breeding model and manure resource utilization should be applied to achieve clean culture gradually.更多还原
