Abstract

The invention discloses a standard treatment apparatus for high-phenol-concentration wastewater, wherein a catalytic oxidation pool, an oxidation stabilization pool, a post-biochemistry BAF pool and aclear water pool are sequentially connected through a rear-section transmission pipeline, an effluent pool is connected to the interior of the catalytic oxidation pool through a water inlet pipeline,an ozone generator is connected to the interior of the catalytic oxidation pool through a gas pipeline, the 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 the post-biochemistry BAF pool through the rear-section transmission pipeline, and the clear water pool is connected to one end of a backwash pump, anda 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. According to the present invention, with the standard treatment apparatus, the microbial membrane attached onto the outer surface of the carrier can be prevented from shedding due to the friction between the carriers in the water, the film forming time is short, and the wastewater treatment efficiency is improved.

Description

technical field [0001] The invention relates to a standard-reaching treatment device for high-concentration phenol-containing wastewater, which belongs 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 object of the present invention is to provide a...
