该工程被桐乡市政府列为八大实事工程之一,总投资6000万元,总规模为12万吨/日,其中果园桥水厂为8万吨/日,崇福水厂为4万吨/日,力争在明年5月底前投入试运行。为提高自来水水质,必须针对源水水质有机物污染严重的基础上,再作深度处理,即增加源水预处理和出厂水深度处理等两项工艺。其工艺流程为:生物接触氧化预处理+常规处理+O_3一生物活性炭滤池处理。这样可大大降低源水中的有机物质。
The project was listed by the Tongxiang municipal government as one of the eight practical projects with a total investment of 60 million yuan and a total scale of 120,000 tons per day, of which 80,000 tons per day were for the Orchard Bridge Water Works and 40,000 tons per day for the Chongfu Water Works, Day, and strive to put into trial operation before the end of May next year. In order to improve the quality of tap water, we must make deep treatment on the basis of serious pollution of source water organic matter, namely, increase the two processes of source water pretreatment and factory water depth treatment. The process is: biological contact oxidation pretreatment + conventional treatment + O_3 a biological activated carbon filter treatment. This greatly reduces the amount of organic matter in the source water.
