摘要:
为了探究沼气发酵、氧化塘曝气和堆肥发酵对长江下游典型规模化畜牧养殖业污染排放特征的影响,本研究选取长江下游规模化生猪养殖场和奶牛养殖场,采集新鲜畜类(猪/牛)粪便和尿废液以及粪污后续处理的样品,并进行相应的理化指标检测与分析。结果表明,畜类养殖场中的尿废液在经过沼气发酵和氧化塘处理后,化学需氧量(COD)可降低85%以上;而全氮和全磷含量在经过同样处理后,数值大幅下降,其中全氮含量逐渐与氨态氮含量接近;在夏季采集样品时,多西环素和金霉素等抗生素在同样处理条件下可完全降解,但在冬季气温降低时,沼气发酵和氧化塘曝气处理的效果下降,样品中最终仍会有少量抗生素残留;此外,Cu、Zn、Pb、Cd、Cr、As和Hg等7种金属含量检测结果表明,在氧化塘液体样品中,江苏生猪养殖场夏季样品中Pb、Cd、Cr、As和Hg,冬季样品中Cr,安徽奶牛养殖场样品中As,上海奶牛养殖场样品中As和Cr的含量超过了农田灌溉水标准。表明,沼气发酵和氧化塘曝气处理能有效降低长江下游粪污中COD、全氮、全磷、抗生素和部分重金属,但是,金霉素和多西环素在冬天处理后仍有残留,部分液体样品处理后个别重金属仍然超标。
Abstract:
In order to explore the effects of biogas fermentation, oxidation pond treatment and composting fermentation on the pollutant emission characteristics of large-scale livestock breeding in the lower reaches of Yangtze River, the physical and chemical properties of pigs and cows manure samples collected from large-scale farms in the lower reaches of the Yangtze River were analyzed. The results showed that the chemical oxygen demand(COD) of pigs and cows urine could be reduced by more than 85% through biogas fermentation and oxidation pond treatment, but the contents of total nitrogen and total phosphorus in liquid samples reduced greatly. In addition, the content of total nitrogen gradually approached that of ammonia nitrogen. When the samples were collected in summer, the antibiotics such as doxycycline and chlortetracycline could be completely degraded under the above treatment conditions. However, in winter, antibiotic degradation was hampered, and the fermented samples still had a small amount of antibiotic residue. The detection results of the contents of Cu, Zn, Pb, Cd, Cr, As and Hg in the liquid samples from oxidation pond indicated that the contents of Pb, Cd, Cr, As and Hg in summer and the content of Cr in winter in the samples of Jiangsu pig farm, the content of As in the samples of Anhui dairy farm and the contents of As and Cr in the samples of Shanghai dairy farm exceded the standard of farmland irrigation water. The treatment of biogas fermentation and oxidation pond could reduce the COD, total nitrogen, total phosphorus, antibiotics and some heavy metals of the pigs and cows feces in the lower reaches of Yangtze River. The antibiotics such as doxycycline and chlortetracycline could not totally be degraded in winter. The contents of several heavy metals in some liquid samples from oxidation pond still exceeded standard of farmland irrigation water.
