水处理设备在废水处理中的积极作用
The positive role of water treatment equipment in wastewater treatment
去除污染物
Remove pollutants
物理处理设备：如格栅、沉淀池等，可以去除废水中的大颗粒悬浮物、砂粒等杂质，为后续的处理步骤奠定基础。
Physical processing equipment, such as grids and sedimentation tanks, can remove large suspended particles, sand particles, and other impurities from wastewater, laying the foundation for subsequent treatment steps.
化学处理设备：通过添加化学药剂，如絮凝剂、氧化剂等，可以使废水中的溶解性污染物发生化学反应，形成沉淀或易于分离的物质，从而去除重金属离子、有机物等。
Chemical treatment equipment: By adding chemical agents such as coagulants, oxidants, etc., soluble pollutants in wastewater can undergo chemical reactions, forming precipitates or easily separable substances, thereby removing heavy metal ions, organic matter, etc.
生物处理设备：利用微生物的代谢作用，将废水中的有机污染物转化为无害的物质，如二氧化碳、水和微生物细胞等。常见的生物处理设备有活性污泥法、生物膜法等。
Biological treatment equipment: utilizing the metabolic process of microorganisms to convert organic pollutants in wastewater into harmless substances such as carbon dioxide, water, and microbial cells. Common biological treatment equipment includes activated sludge process, biofilm process, etc.
回收利用水资源
Recycling and reusing water resources
膜分离技术设备：如反渗透、超滤等，可以去除废水中的溶解性固体、有机物和微生物等，生产出高质量的再生水，可用于工业生产、农业灌溉、城市绿化等领域，实现水资源的回收利用。
Membrane separation technology equipment, such as reverse osmosis and ultrafiltration, can remove dissolved solids, organic matter, and microorganisms from wastewater, producing high-quality regenerated water that can be used in industrial production, agricultural irrigation, urban greening, and other fields to achieve the recycling and utilization of water resources.
