摘要
考察了在不同粒径、不同滤速和混凝剂不同投加量的情况下 ,核桃壳滤料对洗井废水中油和浊度的去除效果。经试验比较 ,最后确定粒径范围为 0 .45～ 0 .9mm,最佳滤速为 1 0 m/ h,混凝剂投加量为 1 0 mg/ L。
This paper attempts to present the author's experiment on a new method of raising the removal efficiency rate of oil and turbidity by using the smashed walnut's shell as a filter medium. The author has investigated and experimented the filtration rate and dosing amount of coagulant by using the smashed walnut's shell with different grain sizes and drew the conclusion that the optimum filtration rate happens to be 10 m/h with the dosing amount of coagulant being 10 mg/L when the grain size ranges between 0.45 mm to 0.9 mm.
