Abstract

The invention discloses a coal gasification phenol water pollution-free circulation 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 gasification phenol water pollution-free circulation treatment method, the good effects of wastewater COD removal, decolorization, deodorizing, toxic pollutant degradation and wastewater biodegradability improving can be provided.

Description

technical field [0001] The invention relates to a pollution-free circulation treatment method of coal gasification phenol water, which belongs to the technical field of waste water 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 polluti...
