　　In the field of industrial cleaning, multi slot independent drainage systems have become core equipment in precision manufacturing, semiconductor processing and other industries due to their efficient and precise cleaning capabilities. The system achieves gradient utilization of cleaning solution and graded treatment of pollutants through a series design of multi-stage cleaning tanks. This article will systematically elaborate on the classification and management system of cleaning solutions from both technical principles and engineering practices, providing the industry with a solution that combines theoretical depth and practical value.

　　一、清洗液分类的必要性

　　1、 The necessity of classifying cleaning solutions

　　多槽独立排水系统的清洗液需根据化学特性、污染程度及工艺要求实施差异化管理。若采用“一刀切”的管理模式，将导致以下问题：

　　The cleaning solution for a multi tank independent drainage system needs to be managed differentially based on its chemical characteristics, pollution level, and process requirements. If a one size fits all management model is adopted, it will lead to the following problems:

　　清洗效率衰减：交叉污染会破坏清洗液的表面活性，使接触角增大，导致清洗盲区扩大。

　　Deterioration of cleaning efficiency: Cross contamination can damage the surface activity of the cleaning solution, increase the contact angle, and expand the cleaning blind spot.

　　设备腐蚀加剧：不同pH值清洗液混合后，可能产生电化学腐蚀，缩短设备使用寿命。

　　Equipment corrosion intensifies: After mixing cleaning solutions with different pH values, electrochemical corrosion may occur, shortening the service life of the equipment.

　　废水处理成本攀升：混合废水中的重金属、有机物等污染物浓度波动大，增加生化处理难度。

　　The cost of wastewater treatment is rising: the concentration of pollutants such as heavy metals and organic matter in mixed wastewater fluctuates greatly, increasing the difficulty of biochemical treatment.

　　二、清洗液分类管理体系

　　2、 Classification Management System for Cleaning Liquids

　　1. 化学特性分类

　　1. Classification of chemical properties

　　酸性清洗液：以氢氟酸、柠檬酸等为主要成分，用于去除金属氧化物。需采用聚丙烯（PP）材质容器存储，避免与碱性物质共用管路。

　　Acidic cleaning solution: mainly composed of hydrofluoric acid, citric acid, etc., used to remove metal oxides. Polypropylene (PP) material containers should be used for storage to avoid sharing pipelines with alkaline substances.

　　碱性清洗液：以氢氧化钠、碳酸钠等为核心组分，针对有机物污染。存储容器需内衬环氧树脂涂层，防止碱液渗透。

　　Alkaline cleaning solution: with sodium hydroxide, sodium carbonate and other core components, targeting organic pollution. The storage container needs to be lined with epoxy resin coating to prevent alkali solution from penetrating.

　　有机溶剂：包括异丙醇、丙酮等，用于溶解非极性污染物。需配备防爆型存储柜，并设置气体浓度监测装置。

　　Organic solvents: including isopropanol, acetone, etc., used to dissolve non-polar pollutants. Explosion proof storage cabinets and gas concentration monitoring devices are required.

　　2. 污染程度分级

　　2. Classification of Pollution Levels

　　新液：未使用的原始清洗液，需建立批次管理制度，记录生产日期、有效期等关键参数。

　　New liquid: Unused original cleaning solution, batch management system needs to be established to record key parameters such as production date and expiration date.

　　在役液：正在清洗槽中循环使用的液体，需实施动态监测，包括电导率、pH值、浊度等指标。

　　In service fluid: a liquid that is being circulated in the cleaning tank and requires dynamic monitoring, including indicators such as conductivity, pH value, turbidity, etc.

　　废液：达到更换阈值的清洗液，需根据污染物类型进行预处理，如重金属沉淀、有机物萃取等。

　　Waste liquid: Cleaning solution that reaches the replacement threshold needs to be pretreated according to the type of pollutant, such as heavy metal precipitation, organic matter extraction, etc.

　　3. 工艺流程分段

　　3. Segmented process flow

　　预清洗段：使用去离子水或弱碱性清洗液，去除大颗粒污染物。该段清洗液需高频次更换，防止颗粒物累积。

　　Pre cleaning section: Use deionized water or weakly alkaline cleaning solution to remove large particle pollutants. This cleaning solution needs to be replaced frequently to prevent the accumulation of particles.

　　主清洗段：采用高活性清洗液，针对特定污染物进行深度清洁。需配置在线过滤装置，维持液体洁净度。

　　Main cleaning section: using highly active cleaning solution for deep cleaning of specific pollutants. An online filtering device is required to maintain the cleanliness of the liquid.

　　Rinse section: Use ultrapure water for final rinsing to ensure that there are no residues on the surface of the workpiece. The water quality of this section needs to meet the standard of electrical resistivity ≥ 18M Ω· cm.

　　三、分类管理实施策略
