Abstract

펄프 폐수처리장에서 생성된 케이크상의 펄프 슬러지를 탈수하고, 상기 탈수된 슬러지를 건조하고, 상기 건조된 슬러지를 700내지 1000℃의 소각로에서 소각하고, 상기 소각된 슬러지를 직경 0.1 내지 2㎜로 파쇄하는 공정을 포함하는 펄프 슬러지 소각잔재로부터 응집제의 제조방법에 의하여 제조된 응집제는 종래의 응집제인 소석회를 이용하여 응집을 실시하는 경우와 비교할 때 그 응집 효과는 거의 동일하며, 폐기물을 재사용함으로써 저렴한 가격으로 제조할 수 있는 매우 경제적인 응집제이다.Dewatering the cake-like pulp sludge produced in the pulp wastewater treatment plant, drying the dewatered sludge, incinerating the dried sludge in an incinerator at 700 to 1000 ° C., and crushing the incinerated sludge to a diameter of 0.1 to 2 mm. The flocculant produced by the method of producing a flocculant from the pulp sludge incineration residue including the process is substantially the same as compared with the case of flocculation using slaked lime, which is a conventional flocculant. It is a very economical flocculant that can be prepared.
