| Abstract: | In the paper, ethylene waste alkali liquor was treated by the precipitation method over copper oxide. Through single factor experiment, the effects of reaction time, reaction temperature and copper oxide dosing quantity on removal rate of sulfur in the waste alkali liquor were investigated. The optimum conditions of precipitation method are： response time 40 min, reaction temperature 30 ~C, copper oxide dosage 1.8 g. Under the optimum conditions, the concentration of sulfur in wastewater was decreased from 1113.25 mg/L to 1.98 mg/L, the COD was decreased from 800000 mg/L to 5600 mg/L. The sulfur removal rate and the COD reached 99.82 %, 99.9 % respectively. |
