上海自来水市南公司长桥水厂水源引自青草沙水库,由于库存停留时间较长,PH升高,冬季硅藻、夏季蓝绿藻污染严重,造成水质异味较重。原水水体中70%以上是小于3K的小分子有机物,常规的净水工艺只能去除30%大分子有机物,对大部分溶解性小分子有机物的去除能力很低,而粉末活性炭处理工艺,可有效快速吸附去除水体中各类天然和合成的有机物、微污染物质、芳香族化合物、卤代烃以及铁、锰、重金属离子等有害物质,防止THMs等致畸、致癌物质的产生,并去除水中的臭味。
The water source of the Changqiao Water Plant of the Shanghai Water Supply Company Nanqiao Company was introduced from the Qingcaosha Reservoir. Due to the relatively long period of inventory retention, PH increased, and diatoms and blue-green algae in summer caused serious pollution, resulting in heavy odour. More than 70% of the original water body is a small molecule organic matter less than 3K. The conventional water purification process can only remove 30% of macromolecule organics. The removal ability of most of the soluble small molecule organics is very low, and the powdered activated carbon treatment process can be effective. Rapidly adsorb and remove all kinds of natural and synthetic organics, micro-pollutants, aromatic compounds, halogenated hydrocarbons, iron, manganese, and heavy metal ions and other harmful substances in the water to prevent the generation of teratogenic and carcinogenic substances such as THMs, and to remove water Odor.
