Study on Sudden Cadmium Pollution Emergency Treatment Tests of Drinking Water Source of Cities

Abstract:

The experiment is based on cadmium pollution of Long River in Hechi Guangxi. The results shows that under existing process condition of water plants, dosing PAC separately can make removal rate of Cd²⁺ reach about 60%, only ensuring the inflow water containing maximum 0.01 mg/L Cd²⁺ reach the standard when outflowed. When the inflow water concentration of Cd²⁺ surpasses 0.01 mg/L, existing technology is needed to be improved. If using combined treatment with sodium carbonate and PAC, in condition the dosing quantity of sodium carbonate is 1.1 times than the theoretical molar ratio, and PAC is 15 mg/L, the removal rate of Cd²⁺ reach higher than 90%, making the effluent which Cd²⁺ exceeds the standard by 10 times reach the standard after treated, providing a new idea for emergency treatment on Cd²⁺ pollution of drinking water.
