| 摘 要： | 对猪粪在高温好氧堆制过程中铅、镉、铜、锌全量以及相对含量随时间的变化进行了深入研究.结果表明:猪粪中铅、镉、铜、锌总浓度随着堆腐时间的延长呈不断增加趋势;铅、镉、铜、锌的相对含量呈现先增加后下降的趋势;堆腐温度和pH是影响DTPA-Pb、Cd、Cu和Zn的相对含量变化的主要因素. |

| Abstract: | The total content and the relative content of Pb, Cd, Cu and Zn changing along with the time while the pig manure composting on the condition of high temperature and enough oxygen were inves tigated. The results showed that the total content of Pb, Cd, Cu and Zn in pig manure increased along with the time extending and the relative content increased at first then dropped. Temperature and pH were the key factors to affect the relative content of Pb, Cd, Cu and Zn. |
| Keywords: | pig manure high temperature compost Pb Cd Cu Zn |
