【摘要】 通过改常压洗网、毡为高压冲洗网毡，可节水７０％左右，然后废水进旋转筛可去除ＳＳ及非可溶性ＣＯＤ；再调节ｐＨ值，加碱式氯化铝及ＰＡＭ絮凝，进一步去除ＣＯＤ、ＳＳ．更多还原

【Abstract】 It’s introduced in the paper that by changing ordinary pressure washing nets and felts into high pressure ones,the water can be spared 70% or so. And then make the waste water enter rotary sieve,to get rid of non-emulsifying COD.Thereafter adjusting pH,add basic aluminum chloride and polyacrylamide to there to get rid of COD and SS further.更多还原
