Qingdao Conqinphi Environmental Technology Group Co., Ltd., established in 2015 with a factory spanning 10,000–30,000 square meters and a dedicated team of 201–300 professionals, introduces our premium Automatic COD Wastewater Treatment Machine featuring a robust 316L stainless steel tank. This system is engineered to deliver consistent, high-efficiency chemical oxygen demand removal for industrial and municipal wastewater streams. With a processing capacity of 5 m³ per day and dual-power motors (1.5 kW and 0.75 kW), our machine combines automation, durability, and cost-effectiveness—helping facilities meet discharge standards while minimizing operator intervention.
The core of this equipment is its fully automatic control system, which manages dosing, reaction, sedimentation, and discharge cycles without manual oversight. The 316L stainless steel construction offers exceptional resistance to corrosion and chemical attack, ensuring a long service life even in aggressive wastewater environments. Whether you are treating food processing effluent, textile dyeing wastewater, or chemical plant runoff, this machine provides reliable performance with low maintenance requirements.
Key Features & Technical Specifications
- Automatic Operation: PLC-controlled dosing, reaction, and sludge discharge – reduces labor costs and human error.
- 316L Stainless Steel Tank: Superior corrosion resistance, suitable for acidic/alkaline wastewater; optional insulation available.
- Dual Motor Design: 1.5 kW main agitator + 0.75 kW pump motor – optimized energy consumption for daily 5 m³ capacity.
- Compact Footprint: Skid-mounted design – easy to install in limited spaces, plug-and-play simple.
- Adjustable Parameters: Reaction time, chemical dosage, and settling time can be customized based on wastewater characteristics.
- Low Operating Cost: Energy-efficient motors and precise reagent dosing reduce chemical and electricity expenses.

Why Choose Our COD Treatment Machine?
Simplicity and Reliability: The automatic control system allows you to set parameters once and let the machine run continuously. For facilities with fluctuating wastewater loads, the built-in sensors adjust chemical dosing in real-time, ensuring consistent effluent quality. The 316L stainless steel tank minimizes rust and chemical erosion, which is critical when treating wastewater with high chloride content or extreme pH levels.
Energy Savings: Unlike traditional systems that run pumps and agitators at full speed continuously, our machine uses variable frequency drives (optional) and timers to match energy consumption to actual treatment needs. The 1.5 kW and 0.75 kW motors are sized optimally for the 5 m³/day capacity, reducing unnecessary power waste. Many clients report operating costs 20–30% lower compared to conventional batch treatment systems.
Easy Maintenance: The tank features a large inspection hatch and drain valve, making it easy to clean and inspect interior surfaces. All pumps and valves are standard industrial components, readily available for replacement. Our design also includes a sludge discharge port with automatic timer control, so you don't need to manually remove sludge every cycle.
Versatility: This machine can be adapted for various treatment chemistries: coagulation-flocculation, Fenton oxidation, neutralization, or combined processes. We offer customized dosing tanks for specific reagents (PAC, PAM, NaOH, H₂SO₄, etc.). The PLC logic can be reprogrammed for different sequences, making it suitable for both industrial and municipal applications.
