新疆畜禽养殖面源污染及资源化利用现状

Current situation of non-point source pollution and resource utilization of livestock and poultry breeding in Xinjiang - A case study of Kashgar region

  • 摘要: 【目的】 浅析新疆喀什地区畜禽养殖污染及资源化利用现状、存在的问题以及对畜牧业发展的影响,为提高该地区畜禽养殖污染及促进畜牧业健康可持续发展提供参考。 【方法】 以新疆喀什地区为例,基于对畜禽养殖企业和农户、畜禽养殖、粪污产生和利用情况进行现场调研,针对该地区存在的问题,结合当前成熟的处理技术进行改进,并提出相应对策。 【结果】 喀什地区各县的畜禽粪污排放量存在一定地理差异性,粪污利用率总体差异较小,全区粪污综合利用率85.43%。 【结论】 不同规模养殖场区粪污处理环节和利用模式差异较大,“就地还田”是最常见的方式,少部分规模化养殖场能够实现粪污肥料化商品生产模式,但产品质量存在差异。

     

    Abstract: 【Objective】 This study takes the Kashgar region of Xinjiang as a case study to assess the current status of pollution from livestock and poultry breeding, resource-oriented utilization of waste, existing problems, and their impacts on the development of the animal husbandry sector. 【Methods】 Based on field investigations of livestock breeding enterprises and farmers, including data on breeding scales, manure and wastewater generation, and utilization practices, this study analyzes the region's challenges.It proposes improvements by integrating established treatment technologies and suggests corresponding countermeasures. 【Results】 Significant geographical disparities exist in the discharge volume of livestock manure and wastewater across counties in Kashgar.However, the overall utilization rate shows less variation, with the regional comprehensive utilization rate reaching 85.43%. 【Conclusion】 Manure treatment processes and utilization models vary considerably among farms of different scales."On-site land application" remains the most prevalent method.A small proportion of large-scale farms have adopted commercial fertilizer production models utilizing manure resources, though product quality varies.This research provides references for mitigating pollution from livestock and poultry breeding and promoting the healthy, sustainable development of the animal husbandry industry in the region.
