Abstract

본 발명은 유분과 가용성의 인분을 함유하는 폐수를 응집침전 처리공정으로 처리하는데 있어서, 오일 성분과 인 성분을 동시에 제거하는 방법에 관한 것이다. 본 방법에서는 먼저 황산알루미늄을 첨가한다. 그 후에 고분자 응집제를 포함하는 유분 흡착재를 첨가한다. 이로 인해 인산알루미늄으로서 불용화된 인분 응집체와 유분을 동시에 응집시켜, 이 응집물을 침전 저장 탱크내에서 침전분리시킨다. 종래의 유분 처리와 인분 처리의 두 공정으로 이루어진 처리시설이 불필요하게 된다. 또, 황산알루미늄의 사용량을 통상의 1/4로 줄일 수 있고, 폐수 처리 비용을 대폭 절감할 수 있다.The present invention relates to a method for simultaneously removing an oil component and a phosphorus component in treating wastewater containing an oil component and a soluble phosphorus in a flocculation sedimentation treatment step. In this method, aluminum sulfate is first added. Thereafter, an oil adsorbent containing a polymer flocculant is added. This causes the phosphorus aggregate and oil insolubilized as aluminum phosphate to agglomerate at the same time, and the aggregate is precipitated in the sedimentation storage tank. There is no need for a treatment facility consisting of two processes, a conventional oil treatment and a phosphorus treatment. Moreover, the usage-amount of aluminum sulfate can be reduced to a quarter of normal, and the wastewater treatment cost can be reduced significantly.
