Abstract

The present invention discloses a high-salt phenol-containing organic wastewater treatment method, wherein an ozone generator is connected to the interior of a catalytic oxidation pool through a gas pipeline, a clear water pool is provided with a water inlet hole and a water outlet hole, the water inlet hole of the clear water pool is connected to a post-biochemical BAF pool through a rear-sectiontransmission pipeline, the clear water pool is connected to one end of a backwash pump, the other end of the backwash pump is connected to the interiors of the catalytic oxidation pool and the post-biochemical BAF pool through a rear-section reflux pipeline, the catalytic oxidation pool is filled with ozone catalytic particles in a fixed bed form, the ozone catalytic particles comprise active alumina particles, copper oxide, titanium dioxide, polyethylene glycol and polyvinyl alcohol, and a carrier comprises, by weight, high-density polyethylene, a polypropylene resin, slaked lime, Dow powderactive carbon, light calcium carbonate and maleic anhydride. According to the present invention, with the high-salt phenol-containing organic wastewater treatment method, under the actions of filtration, biological flocculation and biological adsorption of the biological bed, the organic substances and other substances contained in the wastewater are further adsorbed and oxidized so as to integrate the advantages of low biochemical treatment cost and efficient advanced oxidation efficiency.

Description

technical field [0001] The invention relates to a treatment method for high-salt phenol-containing organic wastewater, belonging to the technical field of wastewater treatment. Background technique [0002] At present, the treatment methods for phenolic wastewater mainly include extraction method, adsorption method, chemical oxidation method, biochemical treatment method and so on. The extraction method consumes a lot of energy, and it is easy for the extractant to remain in the subsequent wastewater, which affects the subsequent treatment process; the adsorption method is simple to operate and is suitable for wastewater with low phenol content, but the one-time investment in equipment is large, and the regeneration of the adsorbent is difficult ; Although the chemical method can oxidize and remove phenol, the operating cost of direct oxidation is relatively high. Contents of the invention [0003] The purpose of the present invention is to provide a treatment method for ...
