硫化砷渣含水率控制试验研究
Control of Water Content in Arsenic Sulfide Slag
摘要
Abstract
The effect of eliminating arsenic process on water content in arsenic sulfide slag was studied.The results show that the precipitation rate of arsenic is 98.04％ and the water content in arsenic sulfide slag is only 29.88％ under the conditions of sodium sulfide amount of 1.1times as much as the theoretical amount, reaction temperature of 40℃, stirring speed of 40r/min, sodium sulfide concentration of200g/L, reaction time of 3hand polymerized ferric sulfate amount of 1.5g/L.By the technology, the annual production cost can be saved 2.0139 million yuan for the enterprises which annual deals with100 thousand cubic meters of waste acid and annual output 6 000 tarsenic sulfide residue.关键词
