The hazards of industrial three wastes
Wastewater pollution
Industrial wastewater contains various harmful substances, such as heavy metals and organic pollutants, which can seriously affect water quality and harm aquatic organisms and human health when they enter the water body.

Waste gas pollution
Industrial waste gas contains a large amount of harmful gases and particulate matter, such as sulfur dioxide, nitrogen oxides, volatile organic compounds, etc. These pollutants not only cause air pollution, but may also lead to environmental problems such as acid rain and greenhouse effect.

Solid waste pollution
If industrial solid waste is not handled properly, it will occupy a large amount of land resources and pollute soil and groundwater through methods such as leachate.
The treatment technology of industrial three wastes

Wastewater treatment technology
Physical methods, such as precipitation, filtration, adsorption, etc., are used to remove suspended solids and partially dissolved pollutants from wastewater.
Chemical method: Removing harmful substances from wastewater through chemical reactions, such as neutralization, oxidation-reduction, flocculation, etc.
Biological method: Utilizing the metabolic activity of microorganisms to degrade organic pollutants in wastewater, such as activated sludge process, biofilm process, etc.

Waste gas treatment technology
Dust removal technology: including gravity settling chamber, cyclone dust collector, bag filter, etc., used to capture particulate matter in exhaust gas.
Gas absorption technology: using liquid absorbents to absorb harmful gases in exhaust gas, such as ammonia absorption method, alkaline absorption method, etc.
Catalytic conversion technology: Under the action of a catalyst, harmful gases in exhaust gas are converted into harmless or low-risk substances, such as catalytic combustion, selective catalytic reduction, etc.

Solid Waste Disposal Technology 
Reduction treatment: Reduce the amount of solid waste generated through measures such as improving production processes and increasing resource utilization.
Resource utilization: converting solid waste into usable resources, such as incineration for power generation, brick making, etc.
Harmless treatment: Solid waste is treated harmlessly through landfilling, solidification/stabilization, and other methods.
The Development Trend of Industrial Waste Management

cleaner production 
Reducing the generation of pollutants from the source is an important direction for future industrial waste management. By adopting clean production technology and processes, we aim to achieve green and low-carbon production processes.

circular economy
Promote the resource utilization of industrial waste, form a closed-loop economic system, reduce resource waste and environmental pollution.
technological innovation
Continuously developing new treatment technologies and equipment to improve the efficiency and economy of industrial waste management.
