摘要
The present invention relates to a membrane fouling reduction method of a membrane-bound biological reactor using a divalent cation and a membrane-bound biological reactor using the same. More specifically, calcium cations (Ca 2+), magnesium cations (Mg 2+) and divalent for reducing fouling contributes to microbial flocs (Floc) formed by adequate concentration implanting positive ions in the membrane-coupled biological reaction tank such as It relates to a method and a membrane-bound biological reactor using the same.;The present invention provides a biological method using a bivalent cation which prevents the formation of deposits on the membrane of the reactor by controlling the supply of the divalent cation such that the monovalent and divalent cations in the membrane-bound biological reactor are maintained within a predetermined ratio range. Provided are a method for reducing membrane fouling in a reactor, and a biological reactor for controlling the supply of divalent cations to the reactor. According to the present invention, it is possible to increase the physical cleaning and chemical cleaning cycles of the membrane by promoting the formation of microbial flocs and reducing the formation of deposits on the membrane.;MBR, reactor, sewage, purification, membrane fouling, cation
