溧阳市区域供水改造提升工程设计

Design of regional water supply transformation and upgrading project in Liyang

溧阳市区域供水改造提升工程中天目湖净水厂设计规模近期为4×10^(4)m^(3)/d,远期8×10^(4)m^(3)/d。针对水源水质特点,采用臭氧预处理/混凝+沉淀+过滤/臭氧-生物活性炭过滤工艺,出水水质符合《生活饮用水卫生标准》(GB 5749—2006)。介绍了净水厂处理工艺选取、主要构筑物的设计规格参数和供水管网设计,为区域供水改造提升工程设计提供了参考。

The design scale of regional water supply transformation and upgrading project of Tianmu Lake Waterworks in Liyang is 4×10^(4)m^(3)/d for short term and 8×10^(4)m^(3)/d for long term.According to the characteristics of water quality,the ozone pretreatment/coagulation+precipitation+filtration/ozone biological activated carbon filtration process was adopted.The effluent quality could meet the Standards for drinking water quality(GB 5749—2006).The selection of treatment technology,design specification parameters of main structures and design of water supply network were introduced,which provided reference for the design of regional water supply transformation and upgrading project.
