畜禽粪便堆肥中重金属含量实验研究
Experimental Study on Heavy Metal Content in Animal Manure Compost
摘要
Abstract
To investigate and analyze the heavy metal content in livestock and poultry manure compost in Wuwei area,Gansu Province,and provide reference data for solving the environmental pollution caused by heavy metals in livestock and poultry manure compost fields.112 cow manure compost samples,32 pig manure compost samples,and 83 chicken manure compost samples were collected to detect and analyze the content of heavy metal elements such as zinc,copper,manganese,arsenic,cadmium,mercury,and lead.When 10% sawdust is added to animal manure compost,it can effectively absorb and passivate the heavy metal Cu content in cow manure and pig manure,as well as the heavy metal Zn content in cow manure,pig manure,and chicken manure;Adding 10% straw or sawdust during the fermentation of chicken manure compost can reduce the content of heavy metal Cd,while adding 10% straw or sawdust to cow manure and chicken manure compost can reduce the content of heavy metal Pb;The effect of adding 10% straw or sawdust to animal manure compost on the changes in As and Hg content is not yet clear.When composting livestock and poultry manure,the content of copper,zinc,and manganese is relatively high,while the content of metals such as arsenic,cadmium,mercury,and lead is generally low.Some high concentrations of heavy metals come from auxiliary materials.Adding 10% sawdust can reduce the content of copper,zinc,and cadmium,and adding 10% straw can reduce the content of cadmium and lead.关键词
