含砷废水的排放已成为国内外饮用水源最大的安全隐患之一.采用无机盐改性麦糟作为吸附剂，对低浓度含砷水进行吸附试验研究.确定最佳改性条件为1.5 mol/L NaCl与麦糟按1 L∶100 g混合均匀，室温下改性12 h.在不调节pH值（溶液pH值为7），改性麦糟投加量5 g/L条件下，初始浓度为0.1 mg/L 的含砷水可在60 min达到吸附平衡，且最终使出水满足《生活饮用水卫生标准》（GB5749-2006）中砷含量（0.01 mg/L）要求.考察了溶液共存阴离子对改性麦糟吸附含砷水的影响，并验证了NaCl改性麦糟处理含砷水源地水的效果.

The outlet of wastewater containing arsenic is one of the greatest potential safety hazards in the source of drinking water. Spent grains modified by inorganic salt used as adsorbent to treat water with low concentration arsenic is studied in this paper. The optimal modification condition is the well mixture of 1.5 mol/L NaCl with grains at ratio of 1 L∶100 g and modification for 12 h at room temperature. Without adjusting the pH value (the solution pH was 7), when modified grains dosage is 5 g/L, the initial arsenic concentration 0.1 mg/L can reach the adsorption equilibrium at 60 min. The arsenic in effluent can meet the requirement of the arsenic content of 0.01 mg/L in “Standards for Drinking Water Quality” (GB5749-2006). The influence of coexisting anions on the arsenic adsorption by NaCl modified spent grains is investigated, and the effect of the NaCl modified spent grains used for treating actual arsenic-containing source water is testified.
