对于大型猪场粪污处理系统工程的建设,以河北京安瑞能环境科技有限公司为例,其处理模式在于:猪场粪污通过提升井进入预处理系统,粪污浓度2%,经初步处理后进入厌氧发酵罐,制出沼气进入双膜储气柜,通过脱硫、脱水、增压进行发电,并入国家电网。发电机余热回收用于发酵罐增温。其养农有机肥厂的原料来源于公司沼气综合利用项目产生的沼渣和沼液。沼肥中包
For the construction of large-scale pig farm sewage treatment system project, with Beijing Jing An Ruineng Environmental Technology Co., Ltd., for example, the treatment mode is: pig farm manure into the pretreatment system through the shaft, sewage concentration of 2%, preliminary After treatment into the anaerobic fermentation tank, biogas system into the double-membrane gas tank, through desulfurization, dehydration, supercharging for power generation, into the national grid. Generator waste heat recovery for fermentation tank warming. The raw materials for its organic farming plant come from the biogas residue and biogas produced by the company’s biogas comprehensive utilization project. Marsh fertilizer package
