摘要
观察家蝇幼虫 (蝇蛆 )生态处理猪粪后 ,猪粪中粪臭素和排污量的变化。以养猪场的猪粪为试验材料 ,经当地蝇蛆处理的猪粪作为处理组 ,未经蝇蛆处理的猪粪为对照组 ,测定两组猪粪样本中粪臭素 ( 3 -甲基吲哚 ,简称 3 -MI)、CODCr、BOD5和 NH3-N的质量浓度。经蝇蛆处理后每 kg猪粪中的 3 -MI、CODCr、BOD5和 NH3-N分别为 2 .76× 10 - 3、5 6.3 6、14 .84和 3 .41g;对照组中上述物质分别为 3 8.5 8× 10 - 3、12 3 .0 1、60 .0 7和 3 .64 g。经蝇蛆处理后的猪粪中的 3 -MI、CODCr和 BOD5分别减少了 92 .8%、5 4.2 %和75 .3 %;而 NH3-N的含量仅减少 6.3 %。蝇蛆生态处理猪粪可有效减少粪臭素和有机污染物 。
To observe the quantitative change of 3-MI, COD-{Cr} and BOD-5 in the pig manures after ecologically treated by housefly larvae. The pig manures were treated by housefly larvae and the non-treated pig manures as control. The contents of 3-MI, COD-{Cr}, BOD-5 and NH-3-N were determined in treated and non-treated pig manures. The contents of 3-MI, COD-{Cr}, BOD-5 and NH-3-N in 1 kg of treated pig manures were 2.76 mg, 56.36 g, 14.84 g and 3.41 g respectively. The contents of substance above mentioned in the non-treated pig manures were 38.58mg, 123.01 g, 60.07 g and 3.64 g respectively. The contents of 3-MI, COD-{Cr} and BOD-5 in the treated pig manures decreased 92.8%, 54.2% and 75.3% respectively in comparison with those of non-treated control. The variation was significant. But the content of NH-3-N decreased 6.3% only and hadn't significant variation. The ecological treatment of pig manures could decrease the contents of 3-MI, COD-{Cr} and BOD-5 in the pig manures. In consequent it's possible to reduce the environment pollution of pig manures.
