【摘要】 通过对某小区中水工程原水水量和水质特点以及小区有限的占地面积的分析,收集小区内全部生活污水,选用悬浮填料流化床这种独特的工艺,处理后出水水质达到《城市污水再生利用城市杂用水水质》(GB/T18920—2002)标准中城市杂用水水质标准,出水主要用于小区内绿化和洗车。通过技术经济比较,该工艺比传统工艺降低了运行成本;运行结果表明,出水水质比传统工艺有大的提高,为发展小区中水工程提供了很好的参考。更多还原

【Abstract】 According to quantity and quality analysis of wastewater and limited area of a residential district, the suspended packing fluidized bed process was adopted in the reclaimed water system to treat sewage collected from this district. The treated effluent met the miscellaneous water standard (GB/T 18920—2002), mainly used for virescence and car washing in the residential district. Compared with conventional process, the technical economy analysis demonstrated cutting-down in operating cost, and the running result of this system showed great improvement in the effluent quality. So the project provided valuable references for reclaimed (water) system development.更多还原
