对采集白银市靖远县正常产气的1a沼气池沼液和3a沼气池沼液的养分含量、微量元素含量、重金属含量、其它物质含量及pH进行了测定。结果表明，1a沼气池沼液和3a沼气池沼液的养分含量都很丰富，但随着年限的增加，沼液中的养分含量、微量元素含量、重金属含量、其它物质含量及pH也明显增加。同时由于沼液中的重金属含量及有害离子的增多，存在食品安全隐患。

Based on the analysis of biogas slurries collected from the biogas slurry tanks having worked for one year and three years respectively . The result shows that the nutrient content of one year biogas slurry and three years biogas digester biogas slurry is very rich, but with the increase in age, the nutrient content in the biogas slurry and trace elements, heavy metals, pH and other substances increased significantly. At the same time, the acummulated heavy metals and poisonous ions would affect food security.
