Qingdao Conqinphi Environmental Technology Group Co., Ltd. has been a trusted manufacturer of advanced wastewater treatment solutions since 2015. Our High-Temperature Oxidation Reactor for High-Salt High-COD Wastewater is engineered to break down complex organic pollutants under extreme thermal conditions. Built with 304 stainless steel and equipped with a 1.5 kW heating system, this reactor delivers reliable, energy-efficient performance for industries dealing with challenging effluents.
This reactor is specifically designed to handle waste streams with high salinity and high chemical oxygen demand (COD), where conventional biological or chemical methods fail. By utilizing high-temperature oxidation, the reactor achieves over 99% degradation of refractory organic compounds, converting them into harmless carbon dioxide and water. The corrosion-resistant 304 stainless steel construction ensures long service life even in aggressive saline environments.
Key Features & Benefits
- High-Temperature Oxidation Efficiency: Operating temperatures up to 1200°C (optional) ensure complete mineralization of high-COD pollutants, reducing sludge production and disposal costs.
- Robust 304 Stainless Steel Construction: Resists pitting, crevice corrosion, and stress corrosion cracking caused by high chloride content, extending reactor lifespan by 30% compared to standard carbon steel.
- 1.5 kW Electric Heating System: Provides rapid and uniform heat distribution, minimizing energy consumption while maintaining stable reaction temperatures. Energy savings of up to 15% vs. conventional models.
- Customizable Reactor Volume: Available in various sizes from laboratory-scale (1L) to industrial-scale (1000L+), tailored to your flow rate and retention time requirements.
- PLC-Based Automation (Optional): Integrated programmable logic controller enables precise temperature ramping, dwell time control, and remote monitoring via SCADA systems.
- Low Maintenance Design: Easy-access ports for cleaning and catalyst replacement, along with corrosion-resistant internals reduce downtime and maintenance costs.
- Compliance Ready: Designed to meet international environmental discharge standards; auxiliary exhaust gas treatment systems available upon request.

How It Works
The high-salt, high-COD wastewater is pre-heated and introduced into the reactor chamber. Inside, the 1.5 kW heating element raises the temperature to the set point (typically 800–1100°C). Under these conditions, organic compounds undergo thermal decomposition and oxidation in the presence of injected air or pure oxygen. The reaction converts organic carbon into CO₂ and H₂O, while inorganic salts are separated as solid residues or dissolved in the treated effluent. The system can be equipped with a catalyst bed to lower activation energy and increase throughput.
Applications
- Chemical & pharmaceutical industrial wastewater with high salt content (>5% TDS)
- Oil & gas produced water containing refractory COD
- Landfill leachate treatment
- Textile dyeing wastewater with high organic load
- Food processing waste streams with high salinity (pickling, brining)

Frequently Asked Questions (FAQ)
-
Q: What kinds of wastewater can this reactor treat?
A: It is ideal for high-salinity (up to 25% TDS) and high-COD (10,000–200,000 mg/L) streams, including chemical, pharmaceutical, landfill leachate, and textile wastewaters. -
Q: What is the maximum temperature the reactor can reach?
A: Standard models reach 1100°C, with optional upgrades to 1200°C. Customization for higher temperatures is available upon request. -
Q: How is the 1.5 kW heating power distributed?
A: The reactor uses multiple embedded heating elements controlled by a PID loop for even temperature distribution (±5°C uniformity across the chamber). -
Q: Is the reactor suitable for continuous operation?
A: Yes, the design supports both batch and continuous flow modes. For continuous feeding, an optional pre-heater and pressure control system can be integrated. -
Q: Does the 304 stainless steel withstand high chloride levels?
A: 304SS is suitable for chloride concentrations up to 1000 ppm at high temperatures. For higher chloride content, we recommend 316L or duplex stainless steel options. -
Q: What safety features are included?
A: Over-temperature protection, pressure relief valve (if pressurized), automatic shut-off, and gas leak detection are standard. Additional safety interlocks are customizable. -
Q: Can I get a small pilot unit for testing?
A: Yes, we offer laboratory-scale reactors (1L, 5L) for feasibility studies. You can then scale up to production units based on results. -
Q: What is the typical delivery time?
A: For standard configurations, lead time is 30–45 days after order. Custom designs may require 60–90 days depending on complexity.
