Abstract

본 발명은 방류수의 수질을 개선하는 방법에 관한 것으로, 더욱 상세하게는 유기화학 공업에서 발생한 폐수를 미생물을 이용한 폐수 처리법으로 처리한 이후에 최종적으로 방류되는 방류수에, 무기 응결제를 1차적으로 가하여 현탁입자들의 표면 전하를 중화시킨 후, 고분자 응집제를 2차적으로 가하여 가교에 의해 입자를 조대화시킴을 특징으로 하는 방류수의 수질 개선방법에 관한 것이다.The present invention relates to a method for improving the water quality of effluent, and more particularly, to the effluent finally discharged after treating the wastewater generated in the organic chemical industry by the wastewater treatment method using microorganisms, an inorganic coagulant is first suspended and suspended. After neutralizing the surface charge of the particles, and a secondary polymer is added to the coarse particles to coarse particles by crosslinking method of improving the water quality of the effluent.
