摘要
从丙烯腈废水中回收成酸铵用作肥料，与市售硫酸铵肥料进行田间肥效试验比较，结果表明，回收硫酸铵对青菜产量和品质无明显影响，土壤和地下水中重金属含量亦无明显增加，青菜、土壤和地下水中氰化物含量虽略有增加，但都远低于有关卫生标准．
A field experiment on fertilization effect of ammonium sulphate (AS ) recovered from acrylonitrile plant'S waste water was conducted. The experimental results showed that there were no significant differences in yield and quality of pakchoi between the plots fertilized with recovered AS and commercial AS. Heavy metal contents in soil and ground. water were not increased. CN contents in pakchoi,soil and ground water were a littleincreased,but all of them were below standards'
