The invention provides a method for advanced treatment and reuse of wastewater. The method is characterized in that a biochemical device adopting a biological aerated filter comprises a water inlet pipe, a backwashing water inlet pipe, a backwashing air inlet pipe, an aerator pipe, a backwashing drain pipe, a water outlet pipe, water distributors, supporting fillers, ceramic fillers, a cell body and a filter plate, wherein energy consumption is only 60% of that of a contact oxidation method after secondary wastewater is subjected to biochemical treatment in the biological aerated filter and organic pollutants are removed; a separation device of an ultrafiltration pressing film comprises a biological aerated filter water discharging tank, a lift pump, a safety filter, ultrafiltration films, an ultrafiltration water production pipe and an ultrafiltration concentrated water pipe, wherein the ultrafiltration films can be used for intercepting matters with molecular weights of 3*10000-1*10000 and removing most colloidal silicon and organic matters in the water; and an electric-absorption desalting device comprises an ultrafiltration device water discharging tank, a water supply pump, a filtering device, an electro-adsorption module, a water production pipe, a reuse water tank, a regenerative pump and a regenerative water outlet, wherein raw water lifted by the regenerative pump is flushed by a short-circuited and standing module so as to regenerate an electrode, and a pollution discharge process is a backwashing process of the module.
