APPARATUS FOR PRODUCING RECLAIMED WATER BASED ON ELECTROLYSIS AND DOUBLE MEMBRANE TECHNOLOGIES AND METHOD THEREOF

摘要

Provided is an apparatus for producing reclaimed water based on electrolysis and double membrane technologies. The apparatus is disposed with an electrolysis system, an MBR system and a reverse osmosis system. Further provided is a method for producing reclaimed water using the apparatus, comprising the following steps: retrieving biochemical sewage through a water pump (12) and inputting the biochemical sewage into an electrolysis apparatus (13) of the electrolysis system to be electrolyzed, then enabling the sewage to enter an MBR reaction tank (26) through a grid (22) to obtain primary reclaimed water, pumping the primary reclaimed water into the reverse osmosis system with a high pressure pump (45) to separate dialysis water and concentrated water, enabling the dialysis water to enter a reclaimed water storage tank (48) to obtain ultrapure reclaimed water, enabling a part of the concentrated water to flow back for cyclic membrane filtering and separation, enabling a part of the concentrated water to flow back to enter an electrolysis procedure for cyclic use, and discharging the rest part of the concentrated water.
