固體廢物處理與資源化

垃圾滲濾液處理：垃圾填埋場或焚燒廠產生的滲濾液成分復雜、濃度高，活性炭可作為深度處理單元，吸附滲濾液中的難降解有機物和色度，降低 COD（化學需氧量）和 BOD（生化需氧量）。

固廢吸附解毒：處理受污染的污泥，吸附污泥中的重金屬和有機污染物，降低污泥毒性，便于后續填埋或資源化利用（如制建材）。

土壤污染修復

農田土壤修復：針對農藥、化肥殘留或重金屬污染的農田，將活性炭摻入土壤，通過吸附作用固定重金屬離子和有機污染物，降低其生物有效性，減少農作物對污染物的吸收。

工業場地修復：治理化工、冶煉廠遺留的污染場地，用活性炭原位或異位吸附土壤中的有機污染物和重金屬，修復土壤生態，為場地再開發提供條件。

其他環保場景

噪聲治理：多孔活性炭可作為吸聲材料，用于降噪設備，輔助降低工業噪聲。

應急環保處理：突發環境事件（如原油泄漏、化學品泄露）中，活性炭可快速吸附泄漏的有機污染物，防止污染擴散。

Water Pollution Control (Core Application Area)

Advanced treatment of domestic sewage: Used for deep purification at the end of wastewater treatment plants, it adsorbs residual organic matter, color, and odor substances (such as humic acid and detergent residues) in the water, improving effluent quality to meet reuse or discharge standards.

Industrial wastewater treatment: Targeting wastewater from industries such as chemicals, dyeing, pharmaceuticals, and electroplating, it adsorbs refractory organic compounds (e.g., phenols, aromatic hydrocarbons), heavy metal ions (e.g., mercury, lead, chromium), pigments, and toxic pollutants to reduce wastewater toxicity and ensure the efficiency of subsequent biochemical treatment.

Drinking Water Purification: As the core filtration material for water purifiers and purification devices, it removes residual chlorine, pesticide residues, odors, and trace organic pollutants from tap water, enhancing the taste and safety of drinking water. It is also suitable for emergency response in cases of sudden water pollution incidents.

Aquaculture water quality regulation: Adsorbs ammonia nitrogen, nitrite, uneaten feed, and decomposed excreta in the water body, improving water quality and reducing fish and shrimp diseases.

Air Pollution Control

Exhaust gas treatment:

Industrial exhaust gas: Treatment of toxic and harmful gases such as VOCs (volatile organic compounds), benzene series, and formaldehyde emitted from industries like chemical manufacturing, painting, and printing. It is often combined with catalytic combustion and adsorption-desorption processes to achieve compliant emissions.

Flue gas purification: After desulfurization and denitrification in coal-fired power plants and steel mills, activated carbon is used to adsorb residual heavy metals such as mercury and dioxins, as well as persistent organic pollutants, thereby reducing the toxicity of the flue gas.

Air purification:

Indoor Air Purification: Produces activated carbon bags and air purifier filters to adsorb formaldehyde, benzene, TVOC, and other renovation pollutants as well as odors.

Public Space Purification: Utilized in new air systems for hospitals, shopping malls, subways, and other venues to eliminate odors, bacterial carriers, and harmful gases from the air.

Automotive Exhaust Purification: Some exhaust purifiers incorporate activated carbon to assist in adsorbing small-molecule organic compounds and odors from the exhaust.

Solid Waste Treatment and Resource Recovery

Landfill leachate treatment: The leachate generated by landfills or incineration plants has complex compositions and high concentrations. Activated carbon can serve as a deep treatment unit, adsorbing refractory organic matter and color in the leachate, thereby reducing COD (Chemical Oxygen Demand) and BOD (Biochemical Oxygen Demand).

Solid waste adsorption and detoxification: treating contaminated sludge by adsorbing heavy metals and organic pollutants within it, reducing sludge toxicity to facilitate subsequent landfilling or resource utilization (e.g., production of building materials).

Soil pollution remediation

Farmland Soil Remediation: For farmland contaminated with pesticide, fertilizer residues, or heavy metals, activated carbon is incorporated into the soil to adsorb and immobilize heavy metal ions and organic pollutants, reducing their bioavailability and minimizing the uptake of contaminants by crops.

Industrial site remediation: Addressing contaminated sites left by chemical and metallurgical plants, utilizing activated carbon for in-situ or ex-situ adsorption of organic pollutants and heavy metals in the soil, restoring soil ecology, and creating conditions for site redevelopment.

Other environmental protection scenarios

Noise Control: Porous activated carbon can serve as an acoustic absorption material, utilized in noise reduction equipment to assist in lowering industrial noise.

Emergency Environmental Treatment: In sudden environmental incidents (such as crude oil spills or chemical leaks), activated carbon can rapidly adsorb leaked organic pollutants to prevent contamination spread.
