摘　　要：为解决温州市西部片区工业园、街道、乡镇供水问题,实现城乡供水一体化,在鹿城区藤桥镇石鼓山山顶建设净水厂。经削山处理后,山顶大小与水厂用地相适宜,山顶高程与供水系统水头配置相吻合,与泽雅水库取水口形成21 m高差,再利用水厂自身高度输配水,实现进水和出水均采用重力自流节能的运行方式,大大降低了工程建设和供水生产成本。净水厂建设规模为20×10^(4)m^(3)/d,一期工程规模为10×10^(4)m^(3)/d,采用强化常规处理工艺,单体构筑物采用一体化设计,节约用地;配套建设DN1200原水管5.43 km、DN1000输水管2.35 km以及相应配水管道16.13 km,并设计几字形上山道路保证交通;配水系统中,通过建设长1.6 km、尺寸为2.60 m×2.85 m的拱顶隧洞,铺设输水管道实现仰义、双屿联网供水。一期工程已稳定运营2.5年,出水水质优于《生活饮用水卫生标准》(GB 5749—2006)。A water treatment plant was built on the top of Shigu Mountain in Tengqiao Town,Lucheng District to solve the problem of water supply for industrial parks,streets and towns in the western area of Wenzhou City and realize the integration of urban and rural water supply.After the mountaintopremoval treatment,the area of the mountaintop was suitable for the land use of the water treatment plant,and the elevation of the mountaintop was consistent with the head of the water supply system,which formed a height difference of 21 m with the water intake of Zeya Reservoir.Therefore,the gravitational flow of water intaking/distribution and energy saving were realized through the water transmission and distribution aided by the elevation of the water treatment plant,which greatly reduced the costs of project construction and water supply.The scale of the water treatment plant is 20×10^(4) m^(3)/d,and the scale of the phase I project is 10×10^(4) m^(3)/d.The enhanced conventional treatment process with integrated design of the structures was adopted to save the footprint area.The supporting systems included 5.43 km of DN1 200raw water transmission pipe,2.35 km of DN1 000 water transmission pipe,and 16.13 km of corresponding water distribution pipe,and the design of zigzag uphill roads was adopted to ensure traffic safety.In the water distribution system,the Yangyi and Shuangyu water supply network was formed through the construction of 1.6 km arch tunnel with the size of 2.60 m×2.85 m and laying water transmission pipe.The phase I project has been in stable operation for 2.5 years,and the effluent quality is better than the limit specified in Standards for Drinking Water Quality(GB 5749-2006).
