摘要
本文研究了四川白皎无烟煤用于生活污水、含铬废水和乐果生产废水的处理。在静态条件下,煤对生活污水中的COD去除率为12%;对乐果生产废水的脱色率大于638%;在含铬工业废水在浓度为3526×10-5mol·dm-3时Cr(VI)的去除率为90%左右。考察了固液比、温度、浓度和酸度等对煤吸附Cr(VI)的影响。
The chromium-containing wastewater and domestic sewage are treared by using coalUnder static condition COD removal ratio of domestic sewage is about 12%,and decolourisation ratio of the wastewater from manufacturing Rogor is over 638%,and removal ratio of Cr(VI)in low concentration solution is around 90%The effect of acidity,temperature,concentration and ratio of Cr(VI) in low concentration solution is arond 90%The effect of acidity,temperature,adsorbate concentration and ratio of adsorbent mass to wastewater volume on adsorption of Cr(VI) are studiedThe relationship between adsorption capacity(q) and adsorption time(t ) is q=47685t(1+21256t)-1or q=21351[1-exp(-05016t)]03838
