摘要：某城鎮(zhèn)水廠生活飲用水供水規(guī)模為3 000 m3/d，水源為地下水。根據(jù)水源水質(zhì)開展工藝設(shè)計，采用“多介質(zhì)過濾器+超濾膜+反滲透膜+次氯酸鈉消毒”工藝處理原水。反滲透后水與濾池后水摻混供水，水質(zhì)穩(wěn)定達(dá)到《生活飲用水衛(wèi)生標(biāo)準(zhǔn)》（GB 5749—2022），為類似新建或改造項目提供參考。

Abstract： The drinking water supply scale of a certain urban water plant is 3 000 m3/d， and the water source is groundwater. According to the water quality of the water source， process design is carried out， and the raw water is treated by using the “multi-media filter + ultrafiltration membrane + reverse osmosis membrane + sodium hypochlorite disinfection” process. The mixed water after reverse osmosis and filter tank is used for water supply， and the water quality is stably meets the Standards for Drinking Water Quality （GB 5749—2022）， thus providing reference for similar new construction or renovation projects.

Keywords： drinking water; groundwater; reverse osmosis; treatment

某城鎮(zhèn)水廠生活飲用水供水規(guī)模為3 000 m3/d，水源為地下水，硝酸鹽含量高于10 mg/L，并逐年升高，經(jīng)檢測，最高含量為19.5 mg/L。（剩余2971字）
