Description

Composite advanced oxidation reactor

Technical Field

The utility model relates to the technical field of wastewater treatment, in particular to a composite advanced oxidation reactor.

Background

Coking wastewater is industrial wastewater which is generally recognized to be difficult to biodegrade, the difficulty lies in poor biodegradability of the wastewater, and the wastewater contains substances which are difficult to biodegrade, such as heterocyclic rings, polycyclic aromatic compounds (PAHS), and the like, such as phenols, naphthalene, pyridine, quinoline, and the like, besides inorganic pollutants, such as ammonia, cyanogen, thiocyanate, and the like, the substances can generate long-term influence on the environment, and part of the substances are researched and proved to be carcinogenic substances, in addition, high-concentration ammonia nitrogen has strong inhibition effect on microbial activity, and the biological denitrification effect is poor. At present, coking wastewater treatment systems typically include conventional two-stage treatment. The first-stage treatment refers to the recovery and utilization of pollutants from high-concentration sewage, and the process comprises ammonia gas distillation, ammonia water dephenolization, final cold water decyanation and the like, and is a pretreatment process. The secondary treatment refers to the harmless treatment of phenol-cyanogen sewage, mainly adopts an activated sludge method, and also comprises an enhanced biological treatment technology and the like. Because the further advanced treatment cost is expensive and is forbidden to many domestic coking plants, most coking wastewater is directly discharged only through conventional two-stage treatment. However, after the wastewater is treated, some toxic and harmful substances (cyanide, COD, heterocyclic compounds and the like) in the wastewater still can not meet the national allowable emission standard.

Ozone has a high oxidation-reduction potential (2.07V) in water, is commonly used for sterilization, disinfection, deodorization, decoloration and the like, and has wide application in water treatment, and ozone has three directions in water: simple physical escape, oxidation of ozone and solutes in water, and decomposition reaction of ozone. However, the decomposition mechanism of ozone varies with the water body properties, and the oxidation capacity is greatly restricted by the water quality.

The ultrasonic wave (40 KHz ultrasonic wave is adopted in the device) can generate cavitation effect, that is, when the sound energy is high enough, the attractive force among liquid phase molecules is broken in a loose half period to form cavitation nuclei. The life of the cavitation nucleus is about 0.1 mus, it can generate local high temperature and high pressure environment of about 4000K and 100MPa at the moment of explosion and generate microjet with strong impact force at the speed of about 110m/s, this phenomenon is called ultrasonic cavitation, the cavitation phenomenon is enough to make the organic matter in the cavitation bubble generate chemical bond rupture, water phase combustion, high temperature decomposition or free radical reaction.

However, in the prior art, in the coking wastewater treatment, the single ozone is adopted to oxidize the coking wastewater or the single ultrasonic wave is adopted to treat the coking wastewater, the oxidative decomposition effect is poor, the COD removal rate is low, the wastewater is deeply treated by chemical agents, the introduced secondary pollution is large, or the subsequent desalting cost is increased, and the coking wastewater treatment cost is increased.
