Abstract

본 발명은 불소 및 HSS 등을 함유하는 폐수처리방법에 관한 것으로서, 원수조에 폐수를 모아, 일정한 농도로 균일화시킨 후, 이에 응집제를 첨가하여 플록을 형성시키고, 그후 상기 플록을 성장시키기 위하여 고분자응집제를 첨가한 후, 플록을 칭감, 분리시키는 폐수처리방법에 있어서, 고분자응집제 첨가시 고분자 응집제와 물을 교반하면서 혼합하고, 그 혼합물을 5~60분간 체류시킨 후 슬러지에 첨가함을 특징으로 한다.The present invention relates to a wastewater treatment method containing fluorine, HSS, and the like, in which a wastewater is collected in a raw water tank, homogenized to a constant concentration, and a flocculant is added thereto to form a floc, and then a polymer flocculant is grown to grow the floc. In the wastewater treatment method of sensitizing and separating flocs after adding, the polymer flocculant and water are mixed with stirring while the polymer flocculant is added, and the mixture is kept for 5 to 60 minutes and then added to the sludge.

본 발명의 방법으로 폐수를 처리하는 경우 플록을 성장시키는데 사용되는 고분자 응집제의 양이 크게 감소되고 이에 따라 폐수처리 비용도 감소되며, 또한 슬러지의 함수율이 감소되어 폐기물의 양이 감소한다.Treatment of wastewater with the process of the present invention significantly reduces the amount of polymer flocculant used to grow flocs, thereby reducing wastewater treatment costs and also reducing the water content of the sludge, thereby reducing the amount of waste.
