生化-物化-生态组合工艺用于离散型住宅小区污水处理与中水回用

以武汉市东西湖区园艺花城小区(3期)污水深度处理和中水回用系统建设为例,介绍和推广一套具有较强实用性的生活污水生化—物化—生态组合处理工艺。该项工艺特别适用于氮含量偏高情况下的离散型住宅小区生活污水深度处理与回用,具有占地省,处理效果稳定,易与周边环境协调等诸多优势。采用组合工艺,可使小区污水经处理后实现达标排放,中水处理系统的出水水质满足《城市污水再生利用(城市杂用水和景观环境用水)水质标准》;系统运行能耗低,污水处理和中水制水的总成本仅为0．69元/m~3。

United Biochemical/Physic-chemical/Ecological Technology Used on Deep Disposal of Domestic Wastewater and Reuse of Treated Water in Distracting Residential Areas

With the example of the wastewater deep disposal and the reclaimed water reuse system of Gardening Resident Park(stage 3)in the East-West District of Wuhan,a kind of biochemical/physic-chemical/ecological united technology of domestic wastewater treatment was recommended for distracting residential areas.With the advantage of stable working efflciency,economy of land occupation and coordination with the surroundings,the united technology was especially ade- quate for the deep disposal and the reuse of domestic wastewater in which the nitrogen content was higher than usual.With the united technology,the domestic wastewater could be treated efficiently and water quality standards for the municipal wastewater reclamation and utilization could be attained.Energy consumption of the treatment system was apparently low- er than others.The cost of the wastewater treatment and the reclaimed water reuse was only 0.69 ynan/m~3.
