多介质土壤层系统处理旅游型村镇生活污水的示范研究

Demonstration Research on Treatment of Domestic Sewage From Tourism-Oriented Rural Towns and Villages With Multi-Soil-Layering (MSL) System

  • 摘要: 采用投资少、处理费用低、运行管理简便的多介质土壤层(multi-soil-layering system,MSL)技术处理旅游型村镇——浙江省安吉县报福镇石岭村生活污水,该污水处理设施的日处理能力约为60 m3·d-1 ,系统稳定运行半年后的监测结果表明,整体系统对COD、TN、NH4+-N、TP及SS的平均去除率分别为82.77%、92.2%、94.1%、89.4%及97.1% ,出水水质可稳定达到GB 18918 —2002《城镇污水处理厂污染物排放标准》中的一级标准。

     

    Abstract: The rapid development of rural tourism has resulted in water pollution in the countryside.Rural tourist spots in Anji County,Zhejing Province are mostly located in remote hilly areas,where no large piece of land for construction of wastewater treatment facilities is available.To solve this problem,a "multi-soil-layering(MSL) technology" featuring low investment,low operation cost,simple operation and management,and small land occupatio was introduced.The treatment capacity of the MSL system is abort 60m3·d-1.After half a year of stable operation,monitoring shows that the effluent of the system is 43.8,5.1,3.1,0.6 and 7.0 m3·d-1 in average concentration of COD,TN,NH4+-N,TP and SS,indicating that their average removal rate being 82.7%,92.2%,94.1%,89.4% and 97.1%,respectively.The quality of its effluent may be stably kept up to the Criteria of Grade I of the "Standard fro Discharge of Pollutants From Urban Sewage Treatment Facilities"(GB 18918-2002).
