摘要
为缓解污水集中处理与生态补水的矛盾问题,青岛西海岸新区采用了“原位处理、就地回用”的分散型污水处理补水模式。通过新建7座分散型污水处理设施,实现了污水就地处理、就近回用、生态补水。7座分散型污水处理设施总处理规模为4.55×104 m3/d,实际运行效果显示,各污水处理设施出水水质优于地表准Ⅳ类水标准,有效解决了城市内河径流不足以及“集中处理,远程调水”模式占地大、投资高等问题,实现了污水资源化,达到了水资源循环利用的目的。分散型污水处理设施采用地埋式建设形式,有效避免了对周边环境的不利影响。通过增加智慧水务管理系统,实现了分散型污水处理设施智慧运管和智能控制,提高了管理效率。采用“原位处理、就地回用”的污水处理理念,既解决了污水增量问题,实现了区域污水的灵活处置,又恢复了河道水体生态质量,获得了良好的环境效益、社会效益和经济效益。
In order to alleviate the contradiction between centralized sewage treatment and ecological water supplement,a decentralized sewage treatment mode for water supplement of“in-situ treatment and on-site reuse”is adopted in Qingdao west coast new area.Through the construction of 7 decentralized sewage treatment facilities with total treatment capacity of 4.55×10^(4) m^(3)/d,sewage treatment,reuse and ecological water supplement have been realized.The actual operation results show that the effluent quality of each sewage treatment facilities are superior to level quasi-Ⅳcriteria in Environmental Quality Standards for Surface Water(GB 3838-2002).It effectively solves the problems of insufficient urban inland river runoff,large land occupation and high investment of“centralized treatment and remote water transfer”mode,so as to realize water quality and resource recycling.The decentralized sewage treatment facilities are built underground,effectively avoiding the adverse impact on the surrounding areas.Through the addition of intelligent water management system,the intelligent management and control of decentralized sewage treatment facilities are realized,and the management efficiency is improved.The sewage treatment mode of“in-situ treatment and on-site reuse”not only solves the problem of sewage increment,realizes the flexible disposal of regional sewage,but also recovers the ecological quality of river water bodies,thus obtaining good environmental,social and economic benefits.
