Study of the COD Release in the Sediment of Tang He Reservoir

Abstract:

The character of COD release in the sediment of Tang He Reservoir was studied under the condition of different concentrations, temperatures, pHs, disturbances, and dissolved oxygen through indoor simulation experiment. It was concluded that sediment could adsorb more organic pollutants when the river was at a higher concentration; whether the temperature was raised or lowered, the COD emission all increased, so the maintenance of temperature could inhibit the release of COD in water; the water stable at the pH of 8; disturbance significantly increased the released quantity of COD; low dissolved oxygen could promote release of COD. The study can provide scientific basis for comprehensive treatment of Tang He Reservoir.
