Abstract
The invention discloses a treatment system for achieving cyclic utilization of phenolic wastewater. The treatment system comprises a catalytic 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 an ozone generator is connected into the catalytic oxidation tank through a gas pipeline, the clean-water tank is provided with a water inlet hole and a water outlet hole, the other end of a backwashing pump is connected to the insideof the catalytic oxidation tank and the inside of the post-biochemical BAF tank through a rear-section backflow pipeline, and a carrier is prepared from, by weight, high-density polyethylene, polypropylene resin, low-density polyethylene, bamboo charcoal powder, wood powder, lignin, dichloromethane, diethyl guanidine sulfate and N,N'-ethylene bis-stearamide. Macromolecular refractory organic matter is oxidized into micromolecular biodegradable organic matter and thus the biodegradability of effluent is improved by adopting the treatment system, and the treatment system can better adapt to wastewater treatment under low-concentration conditions.
Description
technical field [0001] The invention relates to a treatment system for realizing the recycling of 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 treatment...
