| 摘 要： | 针对目前二级城市污水处理厂工程投资高、运行费用高的特点，提出适合中小城市污水处理的工艺——高负荷活性污泥法（HAS）。该工艺不设初次沉淀池，负荷高，泥龄短，污泥沉降性能良好，不存在污泥膨胀，对有机物的去除以絮凝、吸附、沉淀作用为主，对COD、BOD，、SS都有较高的去除效果，对氮、磷有一定的去除作用，出水水质可满足《农田灌溉水质标准》的要求。 |
| 关 键 词： | 城市污水 高负荷活性污泥法 中小城市 污水处理技术 |

| Abstract: | Aiming at high investment ＆ operating cost for secondary municipal wastewater treatment plants, thc High-load Activated Sludge （HAS） process is suggested which is suitable to treat municipal wastewater in medium and small cities. Having no primary sedimentation tank, HAS process has advantages such as high-load, short sludge age, good sludge settleability, no sludge bulking. The HAS process removes pollutants in the ways of flocculation, adsorption and precipitation. It removes COD, BOD and SS in high rate. It also can remove nitrogen and phosphorus. The effluent can meet the requirement of ＂＇ The Standards for Irrigation Water Quality＂ . |
| Keywords: | Municipal wastewater high-load activated sludge process medium and small cities wastewater treatmenttechnology |
