This 300g/h industrial ozone system is an advanced treatment solution for livestock biogas slurry. Ozone breaks down macromolecular pollutants to realize deodorization, decolorization and COD reduction. The all-in-one skid unit integrates air compression, drying and oxygen supply, easy to install on site. Ozone decomposes into oxygen after reaction without secondary pollution, helping farms achieve compliant wastewater discharge or water reuse with lower operating costs.
300g/h Ozone Generator for Biogas Slurry Wastewater Treatment
1. Application Background
Biogas slurry from livestock biogas projects contains high COD, colority, ammonia nitrogen, sulfides and refractory organics. The wastewater is dark and malodorous. Conventional biochemical treatment hardly achieves effective decolorization and deodorization, making it difficult to meet discharge and agricultural reuse standards.
Ozone features strong oxidizing capacity. It breaks macromolecular organic compounds, realizing decolorization, deodorization and pollutant degradation, which is a proven advanced treatment technology for biogas slurry.
2. Equipment Introduction
Model: 300g/h Industrial Ozone Generator (Oxygen-fed Integrated Ozone System)
The whole unit integrates screw air compressor, refrigerated dryer, precision filters, PSA oxygen generator, ozone module and automatic control system. Skid-mounted integrated design allows outdoor direct installation with easy construction.
3. Treatment Principle
When ozone dissolves into biogas slurry, it generates hydroxyl radicals to oxidize contaminants:
✅ Odorous substances (hydrogen sulfide, volatile organic acids) → Odor elimination
✅ Chromophoric macromolecular organics → Water decolorization
✅ Refractory pollutants → COD reduction
Ozone decomposes into oxygen after reaction.
No chemical residue and no secondary pollution.
4. Key Advantages
- Integrated skid system: Air pretreatment + oxygen generation + ozone production. Only pipe connection required for commissioning.
- Excellent advanced treatment: Simultaneously deodorizes, decolorizes and reduces COD of biogas slurry.
- Wide working adaptability: Supports continuous outdoor operation, suitable for farm wastewater stations.
- Low maintenance: No continuous chemical dosing, saving long-term operating cost.
- Eco-friendly process: No extra sludge production.
5. Process Flow
Raw biogas slurry → Precipitation pretreatment → Ozone catalytic oxidation system → Treated water (discharge / agricultural reuse)
6. Application Scope
Advanced treatment of biogas slurry from large-scale pig, cattle and poultry farms;
Purification of anaerobic fermented livestock wastewater;
Upgrading project for biogas slurry tail water.
