摘要
我国餐厨垃圾产量已占城市固体废物的50%以上,推进餐厨垃圾资源化利用和无害化处理是目前亟待解决的问题。某市餐厨垃圾综合处理试项目,由预处理系统、厌氧发酵系统、沼气净化储存系统、沼渣沼液处理系统及除臭系统5部分组成,占地面积19000 m^2,总投资9978万元,处理规模200 t/d,平均沼气产量7740 m^3/d,其中,甲烷含量在60%以上。该餐厨垃圾项目较好地实现了垃圾减量化、资源化,可为其他城市餐厨垃圾处置提供参考。
The output of kitchen waste in China accounts for more than half of the total municipal solid waste.It is an urgent problem to promote the resource utilization and harmless treatment of kitchen waste.The typical comprehensive treatment project of kitchen waste introduced in this paper consists of five parts:pretreatment system,anaerobic fermentation system,biogas purification and storage system,biogas residue and biogas liquid treatment system and deodorization system,covering an area of 19000 m^2,with a total investment of RMB 99.78 million and a kitchen waste treatment scale of 200 t/d.The average biogas output is 7740 m^3/d,in which the methane content is more than 60%.The reduction and recycling of kitchen waste was realized well.It can be taken as a reference for the disposal of kitchen waste in other cities in China.
