| titleOfInvention | Treatment method for waste water |
| abstract | In the wastewater purification method according to the present invention, in the wastewater purification process comprising separating residues from wastewater and purifying waste liquid, ferric sulfate as an oxidant is added to the wastewater while stirring the wastewater at 80 rpm to 100 rpm. Neutralize the mixture, and mix the solid and liquid, and neutralize the mixed solution with the screen separator, centrifuge or filter press. The solid is separated from the mixed solution first, and the waste liquid separated from the mixed solution is bubbled, and 80 rpm-100 rpm After stirring for 0 hours to 5 hours, 1% by weight to 2% by weight of waste liquid was added to the basic solution of sodium hydroxide, and 1% by weight to 2% by weight of one of sodium hydroxide and sodium hypochlorite as the base materials. Into the waste liquid bubbling with agitation and stirred at 2500rpm-3500rpm for 2 hours-7 hours, the waste mixed with base By introducing the flocculating agent and the oxidizing agent to the body, with this, the bubble ringham 80rpm - consists in stirring at 100rpm, and the separator screen in a liquid mixed with a flocculating agent and an oxidizing agent, separated by a secondary one of a centrifuge, filter press or a solid.n n n Therefore, the present invention purifies the wastewater by treating the wastewater physically and chemically by adding the basic agent, the oxidizing agent, and the flocculant to the wastewater while agitating the wastewater and bubbling, thereby reducing general wastewater or high concentration wastewater at low cost. It has the effect of being able to perform the purification process quickly and easily. |
