Organic wastewater treatment system

Abstract

The invention discloses an organic wastewater treatment system. An ozone generator is connected into a catalytic oxidation tank through a gas pipeline, a clean-water tank is provided with a water inlet hole and a water outlet hole, the water inlet hole of the clean-water tank is connected with a post-biochemical BAF tank through a rear-section transmission pipeline, the clean-water tank is connected to one end of a backwashing pump, the other end of the backwashing pump is connected to the catalytic oxidation tank and the inside of the post-biochemical BAF tank through a rear-section backflowpipeline, the catalytic oxidation tank is filled with ozone catalyzing particles in a stationary bed mode, a plurality of biological packings are put in the post-biochemical BAF tank, each biologicalpacking consists of a carrier and a microbial film formed on the surface of the carrier, and the carrier is prepared from, by weight, high-density polyethylene, polypropylene resin, low-density polyethylene, bamboo charcoal powder, wood powder, lignin, dichloromethane, diethyl guanidine sulfate, N,N'-ethylene bis-stearamide, maleic anhydride, dicumyl peroxide and gelatin. The biodegradability of effluent is improved by adopting the system, the purpose of efficiently degrading organic pollutants is achieved, and toxic pollutants are degraded.

Description

technical field [0001] The invention relates to an organic wastewater treatment system, 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 purpose of the present invention is to provide an organic wastewater treatment system, which impr...
