| titleOfInvention | A comprehensive treatment process of electro-throwing waste acid and high-speed iron waste hydrochloric acid |
| abstract | The invention relates to the technical field of hazardous waste disposal, in particular to a comprehensive treatment process for electro-polishing waste acid and high-speed iron waste hydrochloric acid, comprising the following steps: a. The ratio of waste liquid: water is firstly added to the reaction kettle, and the electro-polishing waste acid is treated and spent hydrochloric acid in the reaction kettle by mass ratio of 0.5-1.5:1 respectively; b, adding alkali reaction: stirring the solution in step a, then adding the liquid caustic soda that mass fraction is 30% in the reaction kettle, adjusting The pH value of the solution in the reaction kettle is 6.0-9.0, and the reaction is carried out for 10-20 minutes; c. One-time filter press: the solution in the reaction kettle is exported through a filter press for pressure filtration, the sludge is sent to the landfill, and the filtrate is returned to the reaction kettle; d, add calcium hypochlorite reaction: add calcium hypochlorite to the reaction kettle collectively, react 0.5-2h; e, secondary filter press: export the solution in the reaction kettle and carry out secondary filter press through a filter press, The sludge is sent to the landfill, and the filtrate is analyzed and passed to the biochemical system; the amount of sludge produced is small, the disposal efficiency is improved, the operating cost is reduced, and the waste of land resources is reduced. |
