为了估算青岛市畜禽粪便产生量及主要污染物含量,试验在确定畜禽粪便年排放量的估算方法和排泄系数的基础上,对2012年青岛市畜禽养殖数据进行了估算,并对环境效应进行评价。结果表明:2012年青岛市畜禽粪便总排放量约为1 122.42万t,其中猪、牛排放量较高;畜禽粪便中化学需氧量(COD)、生化需氧量(BOD)、总氮含量(TN)、总磷含量(TP)和水中氨氮(NH3-N)含量分别为28.43,26.68,6.90,2.19,2.96万t左右;农田畜禽粪便负荷量(以猪粪当量计)为29.83 t/hm2,氮、磷养分负荷量分别为164.30,52.06 kg/hm2,畜禽粪便已经开始对环境造成污染。
In order to estimate the amount of livestock excrement and the content of major pollutants in Qingdao, based on the estimation method and excretion coefficient of livestock excrement in the experiment, the data of livestock and poultry breeding in Qingdao in 2012 were estimated, Effect evaluation. The results showed that the total amount of livestock manure in Qingdao in 2012 was about 12,122,400 tons, of which pigs and cattle had higher emissions. The chemical oxygen demand (COD), biochemical oxygen demand (BOD), total nitrogen TN, TP and NH3-N were 28.43, 26.68, 6.90 and 2.196 million t respectively. The excrement load of livestock and poultry in farmland (calculated as pig manure equivalent) was 29.83 t / hm2, nitrogen and phosphorus nutrient load were 164.30,52.06 kg / hm2, livestock and poultry manure has begun to pollute the environment.
