规模化养殖场污水处理工程实例分析
|
摘要
文章针对规模化养殖场污水水质水量特点,采用固液分离-厌氧发酵-A/O曝气-氧化塘组合工艺处理福建省九龙江流域龙岩漳平某规模化养殖场污水。工艺运行结果显示:该组合工艺处理效果良好,COD,BOD_5,SS,NH~+_4-N和TP去除率分别为97.47%,96.30%,99.81%,93.23%和98.24%,最终出水达到《畜禽养殖业污染物排放标准》(GB18596-2001)的要求。其中固液分离出的猪粪渣和曝气池回流的污泥,经堆肥发酵生产有机肥,生产的有机肥亦可达到《有机肥标准》(NY525-2012),具有一定经济效益与推广价值。
According to the characteristics of wastewater quality and quantity of a large-scale farm, a combined process was designed, which including solid-liquid separation, anaerobic fermentation, A/O aeration, and oxidation pond, to treat wastewater for a large-scale farms in Zhangping, Longyan, Fujian province. The results showed that the combined process worked well, and the removal rates of COD, BOD_5, SS, NH~+_4-N and TP were 97.47%, 96.30%, 99.81%, 93.23% and 98.24%, respectively, which reached the discharge standard for livestock and poultry breeding(GB18596-2001). The manure waste produced by solid-liquid separation and the sludge from the aeration tank could be composted for organic fertilizer. The produced organic fertilizer was also reached the standard for organic fertilizer(NY525-2012), which would also have economic and promotional value.
