High salinity wastewater recycling system

Abstract

The invention discloses a high salinity wastewater recycling system. The high salinity wastewater recycling system comprises a catalysis oxidation pond, an oxidation stabilization pond, an after-biochemical BAF pond, a clean water pond, a diluting comprehensive tank, a pretreatment primary BAF pond, a pretreatment secondary BAF pond and a water outlet pond, the catalysis oxidation pond, the oxidation stabilization pond, the after-biochemical BAF pond and the clean water pond are connected in sequence through a rear transmission pipeline, and the catalysis oxidation pond is filled with ozone catalysis particles in the form of a static bed; the ozone catalysis particles are composed of activated aluminum oxide particles, copper oxide, titanium oxide, polyethylene glycol and polyvinyl alcohol; 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 and dicumyl peroxide. The high salinity wastewater recycling system has the good effects of removing COD, removing color, removing odor, degrading poisonous pollutants for wastewater and maintaining the biodegradability of the wastewater.

Description

technical field [0001] The invention relates to a high-salt wastewater recycling 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 a high-salt wastewater recycling system, which ha...
