Coal gas generation furnace phenol-containing wastewater treatment method

Abstract

The invention discloses a coal gas generation furnace 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 pretreatmentfirst-stage BAF pool, a pretreatment second-stage BAF pool and an effluent pool, wherein the catalytic oxidation pool, the oxidation stabilization pool, the post-biochemical BAF pool and the clear water pool are sequentially connected through a rear-section transmission pipeline, 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 powder active carbon, light calcium carbonate, maleic anhydride, gelatin, chitin, ferroferric oxide magnetic powder and manganese-zinc ferrite; and with the coal gas generation furnace phenol-containing wastewater treatment method, the pollutant conversion speed and the pollutantconversion efficiency in the wastewater can be improved, the adsorption force can be generated, and the adsorption on the surface of the filler can be increased.

Description

technical field [0001] The invention relates to a method for treating phenol-containing water of a gas generator, 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 pheno...
