【摘要】 基于对自然循环水处理系统的工艺流程的分析,设置脱氮池、碳氧化池和除磷池,以多种天然材料作为微生物载体,建立小型自然水处理系统,对生活污水进行小型应用试验。结果表明:对于普通的生活污水,该处理系统可以使出水CODcr在30～50mg/L之间,氨氮<5mg/L,总磷<1mg/L,接近于中水回用要求,且处理过程剩余污泥少。更多还原

【Abstract】 Based on analysis of the natural circulating water treatment systems process analysis to nitrogen pools,carbon pool and the phosphorus oxidation pond,a small natural circulating water treatment system is set up and a group of application experiments to domestic wastewaters are tested,with variety of natural materials as microbial carriers.The results show that: for the ordinary domestic sewage,a natural circulation system can make the effluent with CODcr 30～50mg/L,ammonia nitrogen < 5mg/L,total phosphorus < 1mg/L,close to the standard of available reclaimed water,and produces very little sludge during treatment process.更多还原
