活性炭过滤器是一种利用活性炭吸附特性净化水或空气的设备，主要通过物理吸附和部分化学作用去除杂质。
一、核心功能与原理
1、吸附机制
活性炭的多孔结构（比表面积达1200m²/g）可高效吸附余氯、异味、有机物及重金属离子。
对水中的色素、胶体及挥发性有机物（VOCs）有显著去除效果，并能降低COD值。
2、过滤类型
水处理：作为反渗透系统前处理，保护后续设备免受余氯污染，需注意初期使用可能产生的粉末堵塞问题。
空气净化：适用于餐饮油烟处理，结合静电或UV光解技术可提升净化效率。
二、应用场景
家用领域：净水器（如滤水壶、水龙头过滤器）和空气净化器滤芯，需定期更换。
工业领域：废气处理（如漆雾净化）、食品医药行业的水质净化，常用蜂窝活性炭或改性活性炭增强吸附能力。
Activated carbon filter is a device that uses the adsorption characteristics of activated carbon to purify water or air, mainly removing impurities through physical adsorption and partial chemical reactions.
一、 Core functions and principles
1. Adsorption mechanism
The porous structure of activated carbon (with a specific surface area of 1200m ²/g) can efficiently adsorb residual chlorine, odors, organic matter, and heavy metal ions.
Has a significant removal effect on pigments, colloids, and volatile organic compounds (VOCs) in water, and can reduce COD values.
2. Filter type
Water treatment: As a pre-treatment for reverse osmosis systems, to protect subsequent equipment from residual chlorine pollution, attention should be paid to the possible powder blockage problem that may occur during initial use.
Air purification: suitable for the treatment of catering fumes, combined with electrostatic or UV photolysis technology to improve purification efficiency.
二、 Application scenarios
In the household field, water purifiers (such as water filters, faucet filters) and air purifier filters need to be replaced regularly.
Industrial sector: Waste gas treatment (such as paint mist purification), water purification in the food and pharmaceutical industry, commonly using honeycomb activated carbon or modified activated carbon to enhance adsorption capacity.
