Description

Micro-electric field effect integrated device for chemical industry high-salt wastewater treatment

Technical Field

The utility model belongs to the technical field of sewage treatment equipment, and particularly relates to a micro-electric field effect integrated device for treating chemical high-salt wastewater.

Background

Along with the development of society, the demand of various chemical products in human life is increasing, and chemical plants are built in various places, wherein industrial wastewater with complex components, high salt concentration and high biotoxicity can be produced while related products are produced, and if the industrial wastewater is not well treated, the industrial wastewater is very easy to cause irrecoverable harm to the environment. The chemical high-salt wastewater is the end concentrated water of the zero-emission engineering of the chemical enterprise wastewater. The conventional high-salt wastewater in the chemical industry comprises an anaerobic treatment system, an aerobic treatment system, an ultrafiltration UF and nanofiltration NF treatment system, an advanced oxidation treatment system, an activated carbon adsorption system and the like, wherein the conventional process treatment flow is basically as follows, the advanced oxidation system (optional), the biochemical treatment system (anaerobic+aerobic), the advanced oxidation system, the hardness removal system (removing calcium, magnesium, silicon and fluorine and other impurities), the membrane treatment system (ultrafiltration/nanofiltration/reverse osmosis), the evaporation concentration system (MED/MVR/ED electrically driven membrane), the end concentrated water (if the evaporation concentration system is not provided, the reverse osmosis concentrated solution is the end concentrated water), and inert organic matters (COD) in the chemical high-salt wastewater are organic phase impurities which remain after being removed by the conventional wastewater treatment process. The residual inert COD causes 10% -20% of dangerous waste in the subsequent byproduct salt recycling working section, the disposal cost of the dangerous waste is 3000-5000 yuan/ton, and a large economic burden is brought to chemical enterprises.

The existing methods for removing inert COD of chemical industry high-salt wastewater (end concentrated water) are numerous, and mainly comprise an ozone oxidation method, an active carbon adsorption method, a macroporous adsorption resin separation method and the like. However, the ozone oxidation method has the disadvantages of large investment, high operation cost, unsatisfactory effect of removing inert COD, relatively simple process of the activated carbon adsorption method and easy regulation of equipment operation, but has the disadvantages that the adsorption efficiency of the activated carbon to inert organic matters is generally far lower than a theoretical value, so that the treatment effect is poor, the regeneration is difficult after the adsorption saturation, the raw material cost is high, the replaced waste activated carbon belongs to dangerous waste and is unfavorable for environmental protection, and the macroporous adsorption resin separation method is dependent on Van der Waals force or the result of generating hydrogen bonds, also called molecular acting force, which is much weaker than chemical bonds, so that the effect of adsorption separation is very limited for inert COD acted by the chemical bonds, and the characteristics of the resin are not suitable for special environments such as high temperature, high pressure, acid, alkali and the like.

Therefore, how to provide a method for removing inert organic matters remained in chemical high-salt wastewater, which simplifies the process flow, reduces the cost, realizes no hybridization in wastewater treatment, ensures high-value utilization of byproduct salt, and becomes a problem which needs to be solved by the current technicians in the field.
