When the influent COD concentration was increased to 9550-11,800 mg/L(acrylic acid of 6244 mg/L and p-toluenesulfonic acid of 1000 mg/L), the effluent COD was 271-360 mg/L, which satisfied the demand of Class III in Chinese Integrated Wastewater Discharge Standard (GB 8978-1996) at COD loading rates of 7.96-9.83 kg/(m3 x d).

Chemical oxygen demand - Wikipedia

In environmental chemistry, ,the chemical oxygen demand, is an indicative measure of the amount of oxygen that can be consumed by reactions in a measured solution. It is commonly expressed in mass of oxygen consumed over volume of solution which in SI units is milligrams per litre. A ,COD, test can be used to easily quantify the amount of organics in water. The most common application of ,COD, is in quantifying the amount of oxidizable pollutants found in surface water or ,wastewater,. ,COD, …

Wastewater, is any water that has been contaminated by human use. ,Wastewater, is "used water from any combination of domestic, industrial, commercial or agricultural activities, surface runoff or stormwater, and any sewer inflow or sewer infiltration". Therefore, ,wastewater, is a byproduct of domestic, industrial, commercial or agricultural activities.
