Emergency treatment apparatus applicable to catalytic oxidation of high-risk wastewater

Abstract

The invention discloses an emergency treatment apparatus applicable to catalytic oxidation of high-risk wastewater. The emergency treatment apparatus comprises a base plate, an oxidizing agent storage zone, a mixer, a catalytic converter, a pressure water pump and a three-way valve, wherein the oxidizing agent storage zone, the mixer, the catalytic converter and the pressure water pump are all fixedly mounted on the base plate; the wastewater inlet pipe of the apparatus is connected with the water inlet of the three-way valve via the pressure water pump; the other water inlet of the three-way valve is connected with the oxidizing agent storage zone; the water outlet of the three-way valve is connected with the mixer; the mixer is connected with the water inlet of the catalytic converter; and the catalytic converter is provided with a water outlet which is connected with a wastewater outlet pipe. The apparatus provided by the invention treats wastewater by using the principles of cooperation between photocatalysis and chemical catalysis and can realize diversified treatment of a plurality of components in sewage; process conditions of oxidation and degradation are mild; heating is not needed; the range of the acid-base value of sewage is wide; no secondary pollution is produced; and a catalyst is shaped and can be repeatedly and stably used.

Description

technical field [0001] The invention relates to the technical field of high-risk wastewater treatment, in particular to an emergency treatment device suitable for catalytic oxidation of high-risk wastewater. Background technique [0002] Some environmental pollutants have complex structures, high toxicity, and difficult biodegradable substances, such as nitrosodimethylamine, unsymmetrical dimethylhydrazine, hydrazine hydrate, ciprofloxacin, azithromycin, formaldehyde, acetonitrile, etc. These highly toxic and difficult biodegradable substances Degraded substances cannot be detoxified and detoxified by traditional biochemical pools. Once the waste liquid leaks, it will cause serious harm. At present, most of the rapid treatment methods adopt Fenton-like method, ozone oxidation method, physical precipitation method, etc., which have many disadvantages, such as incomplete degradation, serious secondary pollution, high energy consumption, and harsh degradation conditions.

[0002] Some environmental pollutants have complex structures, high toxicity, and difficult biodegradable substances, such as nitrosodimethylamine, unsymmetrical dimethylhydrazine, hydrazine hydrate, ciprofloxacin, azithromycin, formaldehyde, acetonitrile, etc. These highly toxic and difficult biodegradable substances Degraded substances cannot be detoxified and detoxified by traditional biochemical pools. Once the waste liquid leaks, it will cause serious harm

At present, most of the rapid treatment methods adopt Fenton-like method, ozone oxidation method, physical precipitation method, etc., which have many disadvantages, such as incomplete degradation, serious secondary pollution, high energy consumption, and harsh degradation conditions, etc.

[0003] The high-risk wastewater treatment devices currently on the market are generally large-scale treatment pools, which are equipped with a complete set of treatment equipment. The high-risk wastewater generated in the daily production process of the enterprise needs to be connected to the reaction pool through pipeline connections; The laying of the pipeline itself requires cost, and because it is transported through the pipeline, when the pipeline fails and leaks, there will be a great safety hazard in the factory area of ​​the enterprise; and for large-scale reaction equipment, for small-scale or For enterprises with a small amount of waste water, the purchase cost of the equipment is too high and the area is large; and for small batches of sewage, large-scale sewage treatment equipment is obviously expensive; once the equipment fails, the operator needs to Going deep into the equipment for inspection and maintenance, the risk is relatively high, and the maintenance time is long, which affects the normal production of the enterprise
