The effect of tubular type free-radical oxidation depends primarily on the activity of catalyst, and catalyst in the prior art will be kept
Its activity must be maintained within certain operating temperature range.Current technology, tubular type free-radical oxidation method generally utilize instead
System is answered to realize self-heating, but this is really difficult to realize self-heating for the waste water containing auxiliary agent that pollutant concentration changes greatly, because helping
The concentration of agent Wastewater Pollutant changes greatly, so that biggish wave also occurs for its quantity of heat production when carrying out wet oxidation reaction
It is dynamic, cause the temperature of reaction system also to fluctuate therewith, but reaction system operating. temperature fluctuations range it is excessive when, be difficult to
Maintain the temperature of reaction system within the working range of catalyst.
Unresolved above-mentioned technical problem, the present invention in terms of following two by solving:
Firstly, catalyst A is noble ruthenium loaded catalyst in composite catalyst of the present invention, with good catalysis
Activity, though the catalytic activity still with higher under lower operating temperature, but under the high temperature conditions, active component is easy to run off mistake
It is living, and expensive it is unfavorable for industrialized production.And catalyst B is transition metal loaded catalyst, it will be low by oxidant
The manganese ion of valence state is oxidized to the manganese ion of high-valence state, makes it have outside higher leach resistance, and catalyst performance is also more
Stablize, can guarantee that the performance of catalyst is stablized at high temperature.
Mixing of the present invention by Catalyst A Catalyst B according to a certain percentage so that composite catalyst can adapt to it is wider
Temperature range, thus widened the operating temperature of catalyst to a certain extent, can be effectively solved auxiliary agent waste strength not
Temperature of reaction system caused by stablizing fluctuates excessive and then not can guarantee the stable technical problem of catalytic effect, is not necessarily to external temperature
Adjust can efficient tubular type free-radical oxidation auxiliary agent waste water catalytic effect.Specifically, pressing catalyst prepared by the present invention
A, has better low temperature active, and catalysis temperature of charge still ensures that preferable catalytic effect, work temperature at 80 DEG C or so
For degree in 80~180 DEG C of times, its unstable loss of active component of the excessively high catalyst performance of temperature is too fast.But due to itself and catalyst
B's is used in compounding, so that catalyst B plays dominant catalyst at high temperature, avoids the loss of active metal.By the present invention
Catalyst B is prepared, operating temperature still ensures that catalyst is living at 160~400 DEG C under 350 DEG C or more hot conditions
The stability of property, although the operating temperature of catalyst is lower in 160 DEG C or less catalytic activity, since it is compounded with catalyst A
It uses, effectively prevents the insufficient defect of low-temperature catalytic activity.
Secondly, the present invention passes through major pollutants in the concentration detector real-time monitoring sewage being arranged in sewage surge tank
Concentration, and data are passed in microcomputer controller in real time, it is useless that microcomputer controller according to detection data adjusts auxiliary agent
The flow of water, as reduced the discharge of sewage when auxiliary agent waste strength is larger, so that the temperature of reaction system maintains the work of catalyst
Make in range, and ensure that treatment effeciency simultaneously.
