Compared to wet season, arsenic is difficult to mobile in dry season. Attenuation constant in dry season is 0.3082(1/km), but it is 0.0569(1/km)in wet season. If initial concentration of As was 500μg/L without other contamination source in down stream, arsenic would deceased to 50μg/L in down stream 7.5km in dry season but 40km in down stream 40km. As is dominate species in river running throμgh mining area.
砷在枯水期较丰水期难以迁移，通过计算得到，在枯水期砷的衰减系数K值为0.3082(1/km)，而在丰水期为0.0569(1/km)；在污染口浓度达到500μg/L时，下游没有其它的砷的污染源(或会影响砷衰减的其它污染源)时，枯水期砷会在下游7.5km之后浓度降到50μg/L，而丰水期则要在下游40km之后才能降到同样的值，所以在丰水期砷污染的影响的流域更广。

When pH is 10, adsorption time is 30 min, dosage of bone char is 0.6 g/L, the original concentration of As in drinking water is 0.5 mg/L, As removal can reach 95.2%. The adsorption behavior is fitted both with Langmuir and Freundlich isotherm. The adsorption mechanism is supposed to be Ca—OH functional groups combined with anion. And there may occur the co-precipitation between calcium hydrogen arsenate and hydroxylapatite in the aqueous solution, and ions also exchange. The saturation adsorption capacity of As reaches 4.688 mg/g. Indexes of effluent are in good agreement with the WHO stringent drinking water standards (0.01 mg/L).

The results showed that As forms in soils were mainly composed by fixed forms of As when As added at high rate and soil As for ms were mainly composed by labile As,esp.exchangable As,when As added at low rat e.The lability of soil As was improved when astragalusy was added.
结果表明，外源砷浓度高时土壤砷形态以固定态砷为主，外源砷浓度低时以活性态砷为主，尤以交换态砷为主；施入紫云英土壤砷的活性增强；土壤AEC与活性砷含量呈线性正相关。

Theresults indicated that the initial desorption rate of As was higher than As, but thefinal desorption percentage of As was two times higher than As; that in therange of pH(6.5-8.5), the desorption of As was the lowest（pH=6.5）,and thepercentage increased with the pH value increasing or deescalating, but for the As,thepercentage increased with the increase of pH; that the supersonic accelerated desoptionof arsenic and the final percentage was lower than non-supersonic; that on the conditionof UV-light ,in a word, it took negative effect to desorption The"reproduced process"has been used in the procedure of regeneration.
实验结果表明，初始阶段，三价砷的脱附率高于五价砷，但最终脱附率三价砷低于五价砷；三价砷、五价砷在不同温度下的脱附实验表明三价砷的最佳脱附温度低于五价砷的最佳脱附温度；在pH=5.5-8.5时，随着pH的增大，五价砷的脱附率具有先减小再增大的趋势，在pH为6.5时脱附率降至最小；在pH=5.5-8.5时，三价砷的脱附率随pH的增大而增大；不论是三价砷还是五价砷的脱附过程，超声波条件都会促进脱附速率(来源：ecABC论a4文网www.abclunwen.com)的增加，并且最终的脱附率要高于无超声波条件下的脱附率；紫外光照条件下，随着光照时间的增加，两种价态砷的脱附率会达到一个较高的值，再降低。总体而言，紫外光照的存在不利于脱附的进行。

The removal of arsenic from solution has relied mostly on precipitation and adsorption processes and it has been considered that arsenic is the oxidation state that leads to the most effective removal by precipitation since the simple metal arsenates generally have lower solubility than the arsenites, and also arsenate is more strongly adsorbed on certain substrates, but this is pH dependent.
从溶液中去除砷主要依赖沉淀和吸附过程，并且要考虑+5价砷是氧化态，会导致通过沉淀最有效去除砷，因为简单的金属砷酸盐比亚砷酸盐一般有更低的溶解度，并且砷酸盐在特定情况下有更强的吸附能力，但是这取决于 pH 值。
