| titleOfInvention | A treatment method for arsenic-containing wastewater |
| abstract | The invention provides a method for treating arsenic-containing wastewater, which comprises the following steps: adding an oxidizing agent to the arsenic-containing wastewater, stirring for reaction, filtering after the reaction is completed, removing filter residue, and the filtrate enters subsequent treatment; pouring the filtrate into a microwave reactor, Turn on the microwave and heat up, then slowly add iron salt dropwise to carry out the arsenic precipitation reaction under the condition of pH value of 2-3, after the reaction is completed, carry out insulation aging, and then filter to obtain low-arsenic wastewater solution and filter residue, the filter residue is scorodite Add a neutralizer to the low-arsenic wastewater solution to adjust the pH value, then add iron salt to deeply remove the residual arsenic in the low-arsenic wastewater, and the filtrate obtained after filtering is the arsenic-removed wastewater. The treatment method of the present invention uses microwaves to assist in the treatment of arsenic-containing wastewater, effectively improving the wastewater treatment efficiency, effectively reducing the consumption of iron salts in the subsequent deep arsenic removal process, and realizing the reduction of hazardous waste and further reduction of cost. |
