Abstract

The invention discloses a system for purifying organic ammonia-nitrogen wastewater. The 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 oxidationtank through a gas pipeline, the 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 the 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 tankand 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, N,N'-ethylene bis-stearamide, maleic anhydride, dicumyl peroxide and gelatin. The biodegradability of effluent is improved by adopting the system, and the purpose of efficiently degrading organic pollutants is achieved.

Description

technical field [0001] The invention relates to a purification system for organic ammonia nitrogen wastewater, 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 purification system for organ...
