FOUL WATER TRANSACTION A METHOD FOR FOUL WATER REUSABLE WATER OBTAIN OF WATERWORKS STANDARD

摘要

The present invention relates to a sewage treatment method for obtaining sewage recycled water at a tap water level, the configuration of which comprises a first step of flocculating sewage into a sedimentation tank and then coagulating particulate matter and organic matter using a flocculant, The second step of coagulating the remaining particulate matter and organic matter using the special filter aid (Jigusarang Filtering Agent-JFA) in the sewage treated in step 1, and the sewage treated in the second step The sewage treated in the third step and the third step and the sewage treated in the third step are filtered through a high-efficiency Turbidity Removal Filter (HTRF) using Filtering Media (JFM) and filtered through a spiral wound type low pressure reverse osmosis membrane. It includes a fourth step of removing substances and ionic substances, and it is possible to obtain sewage reuse water at a low level with low operating costs. Rather, there is an effect of simplifying the pre-processing step, Lot reduction, stabilization, low operating voltage according to the operation cost reduction, reduction of water costs of the operation and the like.
