★Spraying + low-temperature plasma waste gas treatment process product introduction
The spraying + low-temperature plasma waste gas treatment process is a physical and chemical synergistic treatment technology, mainly for the treatment of medium and low concentrations of VOCs (volatile organic compounds) and malodorous gases containing odor or irritating gases. The system combines liquid absorption with plasma strong oxidation to achieve efficient degradation and purification of waste gas.
In the process, the waste gas first enters the spray tower, and the soluble pollutants in the waste gas (such as acidic gases, particles, and some VOCs) are neutralized or absorbed by alkali, water or reagents, which plays a role in pretreatment and cooling and dust removal; then enters the low-temperature plasma reaction zone, and under the joint action of high-energy electrons, free radicals and ultraviolet light, VOCs are cracked and oxidized into harmless small molecules (such as CO₂, H₂O, etc.).
This technology is widely used in odor control and medium and low concentration organic waste gas purification in industries such as coating, rubber, chemical, printing, food processing, pharmaceuticals, and livestock and poultry breeding.
★Main features
Combined process, synergistic effect
Spray absorption is used to remove front-end particulate matter and water-soluble pollutants, reducing plasma load; plasma deeply oxidizes difficult-to-degrade VOCs to improve the overall treatment effect.
High removal efficiency, suitable for odor control
It has a good removal effect on odorous gases, ammonia, sulfides, aldehydes, ketones, etc., and the comprehensive purification efficiency can reach 80%~95%, which is often used for deodorization and medium-intensity VOCs treatment.
Cold operation, low energy consumption
Low-temperature plasma does not require high-temperature heating, the reaction process is carried out at room temperature or low temperature, the power consumption is small (generally tens to hundreds of watts/cubic), and the energy-saving effect is obvious.
Quick start-up and fast response speed
The equipment does not require long-term preheating or cooling when starting and stopping, which is suitable for intermittent or frequent start-stop exhaust gas emission conditions.
Small footprint, flexible installation
The system has a compact structure and can be modularly integrated, suitable for indoor and outdoor installation, suitable for new or renovation projects, and suitable for local source treatment or centralized governance systems.
No secondary pollution, environmentally friendly
The whole system does not produce wastewater during operation, part of the spray liquid can be recycled, and the plasma products are mainly CO₂ and water, without the need for a post-treatment system.
High degree of automation, simple operation and maintenance
The PLC automatic control system can be configured with functions such as power protection, current monitoring, and high-voltage fault alarm, with a long maintenance cycle and less manual intervention.
Applicable to odor control scenarios in various industries
Especially suitable for industries that are sensitive to odor complaints and have factories adjacent to residential areas, for the treatment of complex pollutants such as odor, organic waste gas, and malodorous gas.

★FAQ

Q. What are the common sewage treatment processes?
A. Common sewage treatment processes include activated sludge method (such as A²/O, oxidation ditch, SBR), biofilm method (such as biofilter, biorotor), membrane bioreactor (MBR), etc. These processes mainly use physical, biological and chemical means to remove organic matter, suspended solids, nitrogen and phosphorus and other pollutants in sewage to achieve standard discharge or water resource reuse.

Q. How is the sludge generated during sewage treatment handled?
A. The sludge generated during sewage treatment needs to be concentrated, dehydrated, stabilized (such as anaerobic digestion) and other treatments to reduce the volume and reduce pollution. The treated sludge can be used as a resource, such as fertilizer, incinerated for power generation, or landfilled. Reasonable disposal of sludge is an important part of ensuring that the entire sewage treatment process meets environmental standards.

Q. Does the sewage treatment plant have a bad smell? How to control the odor pollution?
A. Sewage treatment plants may produce bad smells at water inlets, grit chambers, sludge treatment areas and other places. In order to control the odor pollution, deodorization measures such as sealing facilities, negative pressure collection, chemical washing, biological filters or activated carbon adsorption are usually adopted, and the plant area is reasonably laid out and green belts are set up to reduce the impact on the surrounding environment.
