Zalenol brown coal is low in ash content,good reactivity and relatively large porosity.In our experiments,it was shown that it had good sorptive efficiency for anionic form of Cr~(6+) as well as for various metallic cations(e.g.Cd~(2+),Cu~(2+),Ni~(2+),Zn~(2+)etc.) in aqueous solution.The ion exchange capacity(expressed in mg/g)were 33.5,24,18,12,11,8 and 4 for Cr~(6+),Cd~(2+),Cu~(2+),Ni~(2+),Zn~(2+),Cr~(2+) and Ca~(2+) respec-tively.Either the porosity and chemical structure of coal or the nature of metallic...

Zalenol brown coal is low in ash content,good reactivity and relatively large porosity.In our experiments,it was shown that it had good sorptive efficiency for anionic form of Cr~(6+) as well as for various metallic cations(e.g.Cd~(2+),Cu~(2+),Ni~(2+),Zn~(2+)etc.) in aqueous solution.The ion exchange capacity(expressed in mg/g)were 33.5,24,18,12,11,8 and 4 for Cr~(6+),Cd~(2+),Cu~(2+),Ni~(2+),Zn~(2+),Cr~(2+) and Ca~(2+) respec-tively.Either the porosity and chemical structure of coal or the nature of metallic ions etc.influence the sorption capacity.In this paper,it was indicated that in acidic aqueous solution,anionic Cr~(6+) was reduced to cationic Cr~(3+) by brown coal,and the sorption was occured in solid-liquid interface.The selective coefficients of Cr~(6+) anion with other metallic cations were shown,this provide the basic data for purifying waste water containing chromium ions.

扎赉诺尔褐煤具有灰份低,反应性好、孔隙较大等特点。实验表明,100目的扎赉诺尔褐煤粉对水溶液中以阴离子形态存在Cr~6+和某些金属阳离子(如Cd~(2+)、Cu~(2+)、Ni~(2+)、Zn~(2+),Cr~(3+)、Ca~(2+)等)有较好的吸附能力,交换容量分别为33.5、24、18、12、11、8、4 mg/g,其中以Cr~(6+)最大。这种吸附能力与煤的孔径、化学结构以及金属离子的本性有较密切的关系。实验表明,褐煤粉是在酸性水溶液中使阴离子形态的Cr~(6+)还原成Cr~(3+)阳离子,再进行吸附。文中还列出它对Cr~(6+)和其他金属阳离子的选择系数,为净化各种含铬废水提供了依据。

At drilling sites of the named Company the abandoned drilling mud is diluted properly with water and treated by Al_2(SO_4)_3-based coagulant (or plus a coagulant aim). Often the COD values of the purified waste water are still high. By using coagulant/limie combination the COD values are lowered by 10-60 mg/1 while the use level of the coagulant may be decreased.This way of waste water treating has been put into wide use at drilling sites in East Sichuan.

The removal of Mn(Ⅱ) may be up to 76. 2% in the intermittent infiltration test,but only 24.7% in the continuous infiltration test.There is an aeration condition in...

The capacity of coarse sediments to purify waste water was determined in laboratory by both continuous and intermittent infiltration tests.It was found that more than 50 percent of bacteria,synthetic detergent and total chromium can be removed from the municipal waste water after its infiltrating through a 1.5m thick gravel soil. The removal of Mn(Ⅱ) may be up to 76. 2% in the intermittent infiltration test,but only 24.7% in the continuous infiltration test.There is an aeration condition in coarse sediments when waste water is infiltrating through it,that is advantageous for nitrification.

采用连续和间歇2种注入方式,对粗粒松散沉积物净化污水的能力进行了试验研究。结果表明,1.5m厚的砂卵石层对污水中细菌、合成洗涤剂、总铬等污染物的净化率可达50%以上。间歇注入试验对Mn(Ⅱ)的净化率可达76.15%,而连续注入试验仅为24.7%。污水在粗粒沉积物中的入渗属氧化条件,有利于硝化作用进行。
