Abstract

본 발명은 산업폐수, 생활폐수, 수도원수 등에 첨가하여 부유물의 응집, 유해금속의 제거 등의 효과적인 응집체로서 작용하는 동시에 THMs 및 그 전구물질을 효과적으로 제거하는 수도 등의 정수제(淨水劑)가 되는 응집제조성물에 관한 것이다.The present invention is added to industrial wastewater, domestic wastewater, monastic water, etc., and acts as an effective aggregate such as flocculation of suspended solids and removal of harmful metals, and at the same time, water purifier such as tap water that effectively removes THMs and their precursors. It relates to a flocculation composition.

본 발명은 수용성 알루미늄염과 수용성철염 및 수용성마그네슘염을 원자량비로 Al 1에 대하여 Fe 0.01~2, Mg 0.01~2를 함유하고 그 산화물 Al2O3, Fe2O3, MgO의 합계가 1~15중량%인 신규 응집제조성물을 제공한다.In the present invention, the water-soluble aluminum salt, the water-soluble iron salt and the water-soluble magnesium salt contain Fe 0.01 to 2, Mg 0.01 to 2 with respect to Al 1 in an atomic ratio, and the sum of the oxides Al 2 O 3 , Fe 2 O 3 , and MgO is 1 to 1. It provides a novel flocculant composition of 15% by weight.
