摘要:針對采用傳統(tǒng)化學(xué)淋濾方法處理污水污泥時重金屬溶出率低的問題,設(shè)計了兩種強(qiáng)化化學(xué)淋濾方法的對比試驗,通過檢測重金屬形態(tài)分布、污泥有機(jī)質(zhì)及磷釋放、污泥含固率,研究了強(qiáng)化化學(xué)淋濾對污泥各方面綜合性能的影響。結(jié)果表明:稀硫酸與氯化鐵聯(lián)合處理(處理方法1)對Cu和Cr的溶出效果不明顯,但在加入NaNO2(處理方法2)后使Cu溶出率由7%提升至82%,Zn溶出率由79%提升至88%;同時,兩種強(qiáng)化化學(xué)淋濾方法均增加了污泥中有機(jī)質(zhì)和磷的釋放,污泥中磷含量由23.2 mg/g分別降至12.3 mg/g和10.7 mg/g;與原污泥相比,強(qiáng)化淋濾后的污泥脫水性也均得到了明顯改善,其污泥含固率分別提高了52%和61%。
Abstract:In order to solve the problem of low dissolution rate of heavy metals when using traditional chemical leaching method to treat sewage sludge, contrastive tests of two enhanced chemical leaching methods were designed, and effects of enhanced chemical leaching on comprehensive properties of the treated sludge were explored through determination of heavy metal speciation distribution, sludge organic matters and phosphorus release and sludge solids content. The combined treatment of dilute sulfuric acid and ferric chloride (method 1) had no obvious effect on Cu and Cr dissolution, however, the addition of NaNO2 (method 2) could enhance the Cu dissolution rate from 7% to 82% and the Zn dissolution rate from 79% to 88%. Meanwhile, both methods increased the release of organic matters and phosphorus in sludge, and the phosphorus contents decreased from 23.2 mg/g to 12.3 mg/g and 10.7 mg/g, respectively. Compared with the raw sludge, dewaterability of the enhanced leaching sludge was also improved obviously, and solid contents of the sludge increased by 52% and 61%, respectively.
