摘要
分别采用热预处理和水热预处理耦合零价铁技术,探究其对餐厨垃圾厌氧消化系统性能的影响。结果表明,热预处理及添加零价铁,均能够显著提高产甲烷效果,仅添加零价铁的系统,产甲烷效果最佳,最大产甲烷量是(0.46±0.06)L/(g VS·d),比添加零价铁耦合热预处理和水热预处理技术的CH_(4)产量高出约6%和48%。
In response to this drawback,the system performance of the heat and hydrothermal pretreatment in conjunction with zero-valent iron(ZVI)to treat food waste in the thermophilic AD process was investigated.Heat pretreatment technology can significantly improve the effect of CH_(4)production.The result of(0.46±0.06)L/(g VS·d)was obtained with the addition of ZVI,which is approximately 6%and 48%higher than the specific CH_(4) production of heat pretreatment and hydrothermal pretreatment of food waste,respectively.
