【摘要】：通过对畜禽粪便年排放量的估算方法和畜禽粪便排泄参数的确定,估算了天津市畜禽养殖业粪便产生量并对由此产生的能源与环境效应进行了评价。结果表明,2006~2014年天津市畜禽粪便总量、COD总产量、氮总产量、磷总产量都呈现增长趋势,2014年全市畜禽粪便总量达到约940×10~4 t。天津市耕地总磷负荷和总氮负荷呈现增长趋势,其中耕地总磷负荷自2012年来超过粪肥年施氮限量标准,其中耕地总磷负荷自2014年来超过粪肥年施磷限量标准。2006~2014年天津市的畜禽粪便沼气资源潜力增长趋势,2014年天津市的沼气资源潜力约为4.12×10~8 Nm~3。相当于当年天津市天然气消费量的约6%。
[Abstract]:Based on the method of estimating the annual discharge of livestock and poultry feces and the determination of excretion parameters of livestock and poultry feces, the fecal production of livestock and poultry industry in Tianjin was estimated and the energy and environmental effects were evaluated. The results showed that the total output of COD, nitrogen and phosphorus in Tianjin from 2006 to 2014 showed an increasing trend, and reached 940 脳 10 ~ (4) t in 2014. The total phosphorus load and total nitrogen load of cultivated land in Tianjin showed an increasing trend. The total phosphorus load of cultivated land exceeded the annual nitrogen fertilizer limit standard since 2012. The total phosphorus load of cultivated land exceeded the standard of annual phosphorus application of manure since 2014. From 2006 to 2014, the biogas resource potential of livestock and poultry manure in Tianjin increased, and the potential of biogas resources in Tianjin in 2014 was about 4.12 脳 10 ~ (8) Nm ~ (3). The equivalent of Tianjin's natural gas consumption of about 6.
