Industry knowledge

Industrial waste treatment equipment plays a vital role in environmental protection, resource recovery, and compliant operations. With its high efficiency, intelligent capabilities, and energy-saving features, it has become a crucial support for the sustainable development of modern industry. Jiangsu Haijian Co., Ltd., founded in 1970, is a professional Chinese supplier and manufacturer of industrial waste treatment equipment. Industrial waste treatment equipment is specialized equipment used to treat solid, liquid, and gaseous waste generated during industrial production. Its primary functions include:

Reducing environmental pollution: Treating hazardous waste through physical, chemical, or biological methods to prevent contamination of soil, water, and air. It also reduces the harm of industrial waste to the ecological environment and human health.
Resource recovery: Extracting valuable metals and organic matter from waste for resource recycling. Examples include recycling and pelletizing waste plastics, smelting and regenerating scrap metals, and refining and reusing waste oil.
Reducing disposal costs: Efficient treatment technologies reduce the amount of waste landfilled or incinerated, thereby lowering business operating costs.

Functions of industrial waste treatment equipment
Depending on the type of waste and the treatment method, industrial waste treatment equipment can be divided into the following categories:
(1). Solid waste treatment equipment
Crusher: used to crush large pieces of waste (such as scrap metal, construction waste).
Sorting equipment: such as magnetic separator (metal separation), eddy current separator (non-ferrous metal separation), optical separator (plastic identification).
Compactor: compresses the volume of waste to facilitate transportation and landfill.
Incinerator: burns combustible waste at high temperature to reduce volume and recover heat energy.
(2). Liquid waste treatment equipment
Wastewater treatment system:
Physical treatment (precipitation, filtration)
Chemical treatment (neutralization, redox)
Biological treatment (activated sludge process, anaerobic digestion)
Oil-water separator: separates grease from oily wastewater to prevent pipe blockage and pollution.
Evaporation crystallization equipment: treats high-salt wastewater and recovers reusable salt.
(3) Hazardous waste treatment equipment
Solidification/stabilization equipment: Use cement, asphalt and other curing agents to fix harmful substances (such as heavy metal sludge).
High-temperature melting furnace: Treat hazardous waste (such as medical waste, electronic waste) and make it harmless.
Chemical treatment equipment: Such as acid-base neutralization system, heavy metal precipitation device.
(4) Waste gas treatment equipment
Dust removal equipment: Bag filter, electrostatic precipitator, etc., to remove particulate matter from industrial waste gas.
Desulfurization and denitrification equipment: Reduce the emission of harmful gases such as SO₂ and NOx.
VOCs treatment equipment: Such as activated carbon adsorption, catalytic combustion, biological filter, etc.
