鉴于小型养猪场废水污染成分复杂、处理能力有限等特点,选择生物生态组合工艺作为小型养猪场废水处理的关键技术和工艺。本研究以江西某养猪场为研究对象,基于目前推广的干清粪工艺,设计了一套以“源分离-氧化塘-立体生物滤池-人工湿地”组合工艺处理养猪废水的工程技术方案,并进行效果评价,以满足小型养猪场废水处理经济性和高效性要求。研究结果认为该生物生态组合工艺具有良好的污染物去除效能,出水水质达到《畜禽养殖业污染物排放标准》(GB18596-2001)的一级排放标准。
Abstract
Pig breeding wastewater has the characteristics of complex components and limited treatment capacity. Therefore, bio-ecological technology becomes the key and basic technology for treatment of breeding wastewater from small pig farms. In this study, based on the dry feces process popularized at present, a bio-ecological technology-based combined system with source separation, oxidation pond, three-dimensional bio-filter and constructed wetlands was designed for a small pig farm in Jiangxi Province, and the effect of the system was evaluated. Our results indicated that this system had a high rate of contaminant removal efficiency, and could meet the Discharge Standard of Pollutants for Livestock and Poultry Breeding (GB 18596-2001).
