郑州市D水厂是国内首座日供水20万m3级的强化除砷工程改造水厂,水厂以除铁锰为主、兼具强化除砷,工程运行至今水质处理效果显著,水厂运行稳定,出厂水砷含量稳定在7μg/L左右,铁、锰、浊度等指标均满足《生活饮用水卫生标准》(GB 5749—2006)要求,药剂成本增加约为0.025元/m3,水厂日处理成本增加约为0.50万元,为国内类似的大型集中式供水厂强化除砷提供了宝贵的参考价值和运行管理经验。
Zhengzhou D water plant is the first daily water supply 200000 m3 level of enhanced arsenic removal engineering waterworks, waterworks to remove iron and manganese, both with enhanced arsenic removal, the project has been running water quality treatment effect is significant, the water plant operation stable , The content of arsenic in the ex-factory water is stable at about 7μg / L, and the indexes such as iron, manganese and turbidity all meet the requirements of “Sanitary Standard for Domestic Drinking Water” (GB 5749-2006). The cost of medicament is increased by about 0.025 yuan / Processing costs increased by about 0.50 million for the domestic similar large-scale centralized water supply plant to strengthen the arsenic provides a valuable reference value and operational management experience.
