摘要
[目的]分析以猪粪为原料的沼液成分。[方法]对以猪粪为原料的沼液进行了分析检测,包括pH、营养元素、重金属、总挥发性有机物及抗生素。[结果]猪粪沼液的pH呈微碱性,且随气温升高而升高。沼液中氮、磷、钾含量较为丰富;各种重金属的含量低于国家《城镇垃圾农用控制标准》的标准限值。总挥发性有机物含量为1.365 2 mg/L,OTC为0.083 47 mg/L,TC为0.049 07 mg/L,CTC为0.042 29 mg/L。[结论]该研究为更合理地开发利用沼液奠定了坚实的理论基础。
[ Objective ] The research aimed to analyze the composition of biogas slurry fermented from pig manure. [ Method ] The composi- tion of biogas slurry fermented from pig manure was analyzed, including pH, nutrient, heavy metal, total volatile organic content and antibiot- ic. [ Result] pH of biogas slurry fermented from pig manure was slightly alkaline and rose as temperature increase. Nitrogen, phosphorus and potassium of the biogas slurry were rich, and the contents of various heavy metals were lower than the limited value of Agricultural Usage Con- trol Standard of Urban Garbage. Total volatile organic content, OTC, TC and CTC were respectively 1.365 2, 0. 083 47, 0. 049 07 and 0.042 29 mg/L. [ Conclusion] The research laid solid theoretical basis for further reasonably using biogas slurry.
