Abstract : Composting is an effective pretreatment technology for pig manure (PM) land application. However, nitrogen loss through NH3 volatilization during the thermophilic stage is one of the major drawbacks of composting. The presence of Cu and Zn in compost which come from pig feed additives is also a trouble. In this study bamboo charcoal (BC) and bamboo vinegar (BV) were added into composting piles to investigate their effects on nitrogen conservation and immobility of Cu and Zn during PM composting. During composting, total Kjeldahl nitrogen (TKN) loss decreased with the increasing amount of BC addition and appropriate combinative addition of BV. After composting, TKN loss could be decreased most by 74% with the addition of 3% BC + 0.4% BV, compared with control. Mobility of Cu and Zn also decreased with the increasing amount of BC. The combinative addition of BV could further enhance the immobilization of Cu and Zn. Mobility of Cu and Zn could be decreased most by 35 and 39%, respectively, with 9% BC addition, compared with control. Results of the experiment indicated that adding of BC or BC + BV into PM composting material could be an effective method to reduce TKN loss and mobility of Cu and Zn. Conclusions: The addition of BC or BC + BV into PM composting material influenced the parameter changes. It shorted the time to entering thermophilic phase, decreased pH value at the thermophilic phase, and increased GI of the composting material. Mainly the addition of BC or BC + BV reduced TKN loss and mobility of Cu and Zn in PM composting material. TKN loss could be reduced most by 74% in treatment 3% BC + 0.4% BV. Mobility of Cu and Zn could be reduced most by 35 and 39% in treatment 9% BC. This indicated that the addition of BC or BC + BV into PM composting material were an effective method to reduce negative effects in PM composting.

xuedong78(金币+10,VIP+0):非常感谢热心相助,有些地方改得很好。不过还有几个问题再请教一下:1.我用到most是想说该处理下效果最佳,因为我有多个处理而在摘要里面没有体现出来。2.在这里我用control是表示对照处理的意思,是不是用control treatment会较好?3.因为我的试验已经表明BC和BC+BV的效果较好,所以在”Results of the experiment indicated that adding [of] BC or BC + BV into PM composting material [could be an effective method] has great potential to reduce TKN loss and mobility of Cu and Zn.“中是不是改为”Results of the experiment indicated that adding BC or BC + BV into PM composting material was an effective methodl to reduce TKN loss and mobility of Cu and Zn“更合适? 9-7 19:29

Abstract如下,方括号表删除。 Abstract : Composting is an effective pretreatment technology for pig manure [(PM)]所有abbreviation都挪到正文里 land application. However, nitrogen loss through NH3 volatilization during the thermophilic stage is one of the major drawbacks of composting.[The] Presence of Cu and Zn in compost [which come] from pig feed additives [is also a trouble] still remains a challenge. In this study, bamboo charcoal (BC) and bamboo vinegar (BV) were added into composting piles, to investigate and their effects on nitrogen conservation and immobility of Cu and Zn during PM composting were investigated. During composting, total Kjeldahl nitrogen (TKN) loss decreased with the increasing amount of BC addition and appropriate combinative addition of BV. After composting, TKN loss could be decreased [most] by 74% with the addition of 3% BC + 0.4% BV, compared with control少东西吧?. Mobility of Cu and Zn also decreased with the increasing amount of BC. The combinative addition of BV could further enhance the immobilization of Cu and Zn. Mobility of Cu and Zn could be decreased most by 35% and 39%, respectively, with 9% BC addition, compared with control同上,control啥?. Results of the experiment indicated that adding [of] BC or BC + BV into PM composting material [could be an effective method] has great potential to reduce TKN loss and mobility of Cu and Zn. |
