【摘要】：通過對畜禽糞便年排放量的估算方法和畜禽糞便排泄參數(shù)的確定,估算了天津市畜禽養(yǎng)殖業(yè)糞便產(chǎn)生量并對由此產(chǎn)生的能源與環(huán)境效應(yīng)進(jìn)行了評價。結(jié)果表明,2006~2014年天津市畜禽糞便總量、COD總產(chǎn)量、氮總產(chǎn)量、磷總產(chǎn)量都呈現(xiàn)增長趨勢,2014年全市畜禽糞便總量達(dá)到約940×10~4 t。天津市耕地總磷負(fù)荷和總氮負(fù)荷呈現(xiàn)增長趨勢,其中耕地總磷負(fù)荷自2012年來超過糞肥年施氮限量標(biāo)準(zhǔn),其中耕地總磷負(fù)荷自2014年來超過糞肥年施磷限量標(biāo)準(zhǔn)。2006~2014年天津市的畜禽糞便沼氣資源潛力增長趨勢,2014年天津市的沼氣資源潛力約為4.12×10~8 Nm~3。相當(dāng)于當(dāng)年天津市天然氣消費(fèi)量的約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.
