The present invention relates to a method for preparing poly-ferric sulfate in order to treat sewage by using a waste sulfuric acid generated in a semiconductor process. The method can prevent environmental pollution by recycling the waste sulfuric acid and iron oxide disposed of as byproducts of the process, reduce the amount of residual heavy metals, and obtain high-purity poly-ferric sulfate. According to the present invention, the method includes: a ferric sulfate preparing step of mixing the sulfuric acid and iron oxide disposed of as byproducts of the process in a first reaction tank (10) at a temperature of 80-110°C for one to three hours to prepare ferric sulfate (ST 1); a solution mixing step of mixing the prepared ferric sulfate with a solution of NaFeO_2 and Na_2CO_3 by using a high-speed emulsifier (ST 2); and a heat polymerization step of aging the mixture mixed in the previous step in a second heat polymerization tank (30) at a temperature of 30-80°C for one to four hours ...

Автор: CHO, SUNG SUN, KIM, GI WEON, CHOI, IN CHEOL, CHAE, HO JUN
Принадлежит: NEXTECH. CO., LTD., ATON INDUSTRY CO., LTD.

The present invention relates to a method for preparing a cohesive agent for wastewater treatment using waste resources. More particularly, the method is to obtain AFC by using the precipitate generated in a PAC storage tank and waste resources of ferric oxide generated during a steel making process, and then manufacture a polyaluminum ferric chloride (PAFC) cohesive agent for wastewater treatment having excellent cohesive property through a polymerization reaction. The method includes: a mixing step (ST1) of mixing non-crystalline aluminum hydroxide precipitated in a polyaluminum chloride storage tank, ferric oxide generated during a steel making process and hydrochloric acid in a mixing device (10); a reaction step (ST2) of introducing the resultant mixture into a reactor (20) and carrying out reaction at a temperature condition of 80-110°C for 1-5 hours to form aluminum ferric chloride; and an aging step (ST3) of introducing the AFC formed in the reaction step to an aging device (30) ...
