Problems solved by technology

[0002] At present, the advanced treatment process for high-salt sewage in petrochemical industry mainly includes biological oxidation method and physical-chemical advanced oxidation method. The biological oxidation method is represented by MBR process. Extremely poor (BOD<10), the effect of the biochemical process is limited, and it cannot meet the requirements of the first-class standard for sewage discharge; the advanced oxidation process includes direct contact oxidation with ozone, Fenton reagent, etc., and its disadvantages are unstable treatment effect and high operating costs , produce secondary pollution, etc.

Abstract

The invention discloses a petrochemical waste water discharge treatment device. The device comprises an ozone generator, wherein the ozone generator is connected to the inside of a catalytic oxidationtank through a gas pipeline, a water inlet hole, a water outlet hole and a return hole are formed in a clean water tank, the water inlet hole of the clean water tank is connected to a post-biochemical BAF tank by a transmission pipeline, the water outlet hole of the clean water tank is connected to one end of a backwash pump, and a carrier is composed of, according to parts by weight, high-density polyethylene, polypropylene resin, low-density polyethylene, bamboo charcoal powder, wood powder, lignin, methylene chloride, diethyl sulfonium sulfate, N,N'-ethylene bisstearamide and maleic anhydride; the carrier includes a hollow short pipe, a first concentric ring and a second concentric ring, wherein the first concentric ring and the second concentric ring are sequentially and concentrically disposed on the outside of the hollow short pipe. The device has an ammonia nitrogen removal rate over 92% and a COD removal rate over 78% and can better treat low-concentration wastewater.

Description

technical field [0001] The invention relates to petrochemical wastewater discharge treatment equipment, which belongs to the technical field of petrochemical wastewater. Background technique [0002] At present, the advanced treatment processes for high-salt sewage in the petrochemical industry mainly include biological oxidation and physical-chemical advanced oxidation. The biological oxidation method is represented by the MBR process, and its shortcoming lies in the biodegradability of high-salt advanced treatment sewage Extremely poor (BOD<10), the effect of the biochemical process is limited, and it cannot meet the requirements of the first-class standard for sewage discharge; the advanced oxidation process includes direct contact oxidation with ozone, Fenton reagent, etc., and its disadvantages are unstable treatment effect and high operating costs , produce secondary pollution, etc. Contents of the invention [0003] The object of the present invention is to prov...
