Abstract

The invention discloses a process for advanced treatment of phenolated water at gas station. The treatment process is based on a special treatment device, and the special treatment device comprises acatalytic oxidation tank, an oxidation stabilization tank, a post-biochemical BAF tank, a clean-water tank, an integrated dilution tank, a pretreating primary BAF tank, a pretreating secondary BAF tank and an effluent tank, wherein the catalytic oxidation tank, the oxidation stabilization tank, the post-biochemical BAF tank and the clean-water tank are sequentially connected through a rear-sectiontransmission pipeline. The ozone catalyzing particles are prepared from activated aluminum oxide particles, copper oxide, titanium dioxide, polyethylene glycol and polyvinyl alcohol. A carrier is prepared from, by weight, 60-70 parts of high-density polyethylene, 10-15 parts of polypropylene resin, 6-8 parts of low-density polyethylene, 8-10 parts of bamboo charcoal powder, 4-6 parts of wood powder, 2-3 parts of lignin, 2-3 parts of dichloromethane, 1-2 parts of diethyl guanidine sulfate, 0.5-1 part of N,N'-ethylene bis-stearamide and 3-5 parts of maleic anhydride. Macromolecular refractory organic matter is oxidized into micromolecular biodegradable organic matter and thus the biodegradability of effluent is improved by adopting the process.

Description

technical field [0001] The invention relates to an advanced treatment process for phenol water in gas stations, 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 an advanced treatment process ...
