Abstract

The present invention discloses a phenol-containing wastewater treatment method. According to the present invention, the treatment process is based on a special treatment apparatus; the special treatment apparatus comprises a catalytic oxidation pool, an oxidation stabilization pool, a post-biochemical BAF pool, a clear water pool, a dilution comprehensive tank, a pre-treatment first-stage BAF pool, a pre-treatment second-stage BAF pool and an effluent pool, wherein the dilution comprehensive tank, the pre-treatment first-stage BAF pool, the pre-treatment second-stage BAF pool and the effluentpool are sequentially connected through a front-section transmission pipeline, an ozone generator is connected to the interior of the catalytic oxidation pool through a gas pipeline, ozone catalyticparticles 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 powder active carbon, light calcium carbonate, maleic anhydride, dicumyl peroxide, gelatin, chitin and magnetic powder; and with the phenol-containing wastewater treatment method, the difficulty-degraded macromolecule organic matter is oxidized into the easily-biodegradable small molecule organic matter, such that the biodegradability of the effluent is improved.

Description

technical field [0001] The invention relates to a treatment method for phenol-containing 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 phenol-containing ...
