| 摘 要： | 堆肥过程中产生的臭气容易导致恶臭污染问题.总结了堆肥过程中主要臭气物质的产生机理、物理化学性质、影响因素及调控措施.堆肥过程中产生的臭气物质主要包括NH<,3>、H<,2>S和部分挥发性有机物;H<,2>S是堆肥过程产生的恶臭潜力最高的臭气;NH<,3>的最大释放浓度可达6 000 mg/m<'3>.堆肥原料的C/N值、调理剂种类、通风条件是影响氨气挥发的重要因素.指出过程控制是解决臭气问题的根本措施.

| Abstract: | Odor produced during composting can easily cause environmental pollution.The production mechanism and physicochemical properties of odorous compounds,impact factors and control measures are summarized.The main odorous compounds generated during composting include ammonia,hydrogen sulfide and some volatile organic compounds.Hydrogen sulfide generated during composting process has the highest odorous potential.The highest concentration of ammonia emitted during composting is up to 6 000 mg/m3.C/N ratio,amendm... |
