摘要
本文通过开展嘉北污水处理厂污泥综合利用试验,研究城镇污水处理厂系统的剩余污泥作为种植土资源化利用的技术路径。结果表明:经与秸秆、生物酶混合熟化后的种植土最终符合《城镇污水处理厂污泥处置-园林绿化用泥质》(CJ-248-2007)的标准要求,可作为油菜、冰草、巨菌草、马鞭草、臭菊等草本植物或花卉等植物的种植土。
In this paper,a comprehensive utilization experiment of sludge in the Jiabei sewage treatment plant was carried out to study the technical path of utilizing surplus sludge in the urban sewage treatment plant system as planting soil resource.The results show that the planting soil after being mixed and matured with straw and biological enzymes ultimately meet the standard requirements of《Sludge Disposal for Urban Sewage Treatment Plants-Mud Quality for Landscape Greening》(CJ-248-2007),and can be used as planting soil for herbaceous plants such as rapeseed,ice grass,giant fungus grass,verbena,stinky chrysanthemum or flowers.
