Method for treating wastewater with trivalent arsenic

The invention discloses a method for treating wastewater with trivalent arsenic. The method includes simultaneously feeding the to-be-treated wastewater with the trivalent arsenic, iron salt solution and sulfate solution and simultaneously sufficiently colliding the to-be-treated wastewater, the iron salt solution and the sulfate solution with one another to obtain first mixtures; regulating the pH (potential of hydrogen) of the first mixtures until the pH of the first mixtures reaches 1.8-3.0; uniformly mixing the first mixtures with one another at the normal temperature; carrying out reaction; separating precipitates. The method has the advantages that feeding reaction is carried out under the conditions of the temperatures of 25+ / -1 DEG C, the speeds of 600+ / -20 r / min and the pH of 2.4 for 18 min when the arsenic solution with the As <3+> content of 20.5 g / L, the iron salt solution with the Fe <3+> content of 23.0 g / L and the sulfate solution with the SO<4><2-> content of 6.56 g / L are added into 30 mL of deionized water at the speeds of 1.8 mL / min, water hydroxyl sarmientite minerals are good in crystallization, and the As <3+> removal rate is 87.6%; the method for treating the wastewater with the trivalent arsenic is high in arsenic removal efficiency, good effects can be realized, raw materials are low in cost and are easily available, conditions are mild, procedures can be controlled, the precipitates are high in arsenic content, are stable and are easy to separate, secondary pollution can be prevented, and accordingly the method has a broad practical application prospect.
