Description
Technical Field
The utility model relates to an organic wastewater treatment device, in particular to an organic wastewater treatment device containing high-concentration bromine and silicon.
Background
The industries such as chemical industry, medical treatment and the like generate a large amount of high-concentration organic wastewater containing halogen in the rapid development process, and if the organic wastewater is not treated in time, the ecological environment is seriously threatened. In the industrial wastewater treatment method, mechanical vapor recompression technology, biochemical treatment, multi-effect evaporation, ion exchange method, membrane separation and other treatment methods are layered endlessly, but the treatment requirements on high-concentration wastewater are difficult to meet due to the defects of high economic cost, secondary pollution, low treatment efficiency and the like. Therefore, advanced oxidation techniques with high processing efficiency have been developed.
Catalytic wet oxidation (CWAO) technology is a representative technology of waste water heat treatment, and the reaction mechanism is that oxygen in air generates strong-oxidability OH free radical on the surface of the catalyst under high temperature and high pressure,oxidizing organic pollutant and poison containing N, S directly to CO 2 And H 2 O and N 2 、SO 4 2- And the like are harmless, thereby achieving the purpose of removing pollutants; no solid waste is generated in the process, and no dioxin, NOx and SO are generated 2 Secondary pollution waste gas is generated; meanwhile, the oxidation reaction heat can be fully utilized in the reaction process, self-heating balance is realized, and the energy conservation is good. The CWAO has the advantages of high removal rate, low operation cost, strong adaptability, no secondary pollution, simple flow, small occupied area and the like, and is paid attention to.
Bromine is an important chemical raw material, and is widely applied to various fields such as chemical industry, medicine and the like, and bromine in wastewater usually exists in an ionic form. At present, the main means for removing bromine at home and abroad are a steam distillation method, a resin exchange method, an air blowing method and the like. CN115557468A discloses a method for extracting bromine from brine, however, the apparatus is numerous and the operation is complex.
In alkaline wastewater, silicon exists in an ionic form, but with the increase of the acidity of the solution or the existence of a large amount of salt, the ionic form of silicon is easy to be converted into a silica gel state, in the advanced treatment process of sewage, the silica gel can block a reactor, a membrane tube and the like, and in the long-term running state of the reactor, the treatment effect is reduced due to the influence of silica scale, and the risk of explosion caused by the blockage is also reduced. If the reactor cleaning frequency is increased, the service cycle of the equipment is reduced, the industrial production operation efficiency is low, and the larger production cost is increased. The common industrial wastewater is subjected to silicon removal, and substances such as calcium and magnesium are removed, so that the risk of secondary pollution is increased. Therefore, pretreatment of silicon in industrial wastewater is of great importance. CN116002931a discloses a method for treating wastewater from molecular sieve catalyst production, however, calcium and magnesium substances are introduced during the silicon removal process, which increases the risk of secondary pollution.
Therefore, it is needed to find an organic wastewater treatment device containing high-concentration bromine and silicon, which has the advantages of simple structure, large treatment capacity, high removal rate of bromine, silicon and COD, environment friendliness, safety, reliability, low energy consumption and low cost and is suitable for industrial production.
