Description
Technical field
The present invention relates to field of waste water treatment, related in particular to a kind of modular catalytic oxidizing equipment.
Background technology
Complicated along with the variation of production technology and application requirements, in the waste water that various industries produce, dirtCan there is the leap of very large degree, the complexity of water quality in component, concentration, colourity, smell and the toxicity of dying thingDegree is very high. Under this overall situation, any single dirty wastewater treatment mode will obtain having generalAll over the popularization of property, its difficulty is well imagined. From the development of modern water technology, compound placeThe reason method development trend that is inevitable, difference be towards the dirty group technology that waste water adopts of different quality andCharacterisitic parameter is different. For different types of waste water, in order to avoid the secondary pollution to environment as far as possible,Biodegradation technique and membrane bioreactor are the main developing direction of dirty wastewater treatment in recent years. But byIn towards the complexity of dirty waste water quality, and due to cycle of the market demand and main body production technology orQuasi-periodicity property feature, due to the strong variations in this cycle or quasi-periodicity itself, the load of general dirty waste waterAll show stronger fluctuation, thereby degradation capability and capacity of resisting impact load to microorganism proposeHigh requirement.
Just because of the feature of water concentration, component and fluctuation, how to improve pollutant on the wholeThe degradation efficiency of matter, under the little prerequisite of low energy consumption, low pollution and floor space, reaches the height to dirty waste waterIntensity processing is the prerequisite essential characteristic of water treatment technology. In view of the biological treatment of biologic treating technique/filmTechnology has become the Developing mainstream of dirty wastewater treatment, so for the dirty waste water of characteristic complexity, and how QuickRising biodegradability, must be the problem that need to put forth effort solution. Catalysed oxidation processes is a kind of relative efficiencyAnd stable method, development is also relatively ripe. From single catalytic oxidation to compound catalytic oxidation technology,To the Research Literature of the dirty Pollutants in Wastewater properties influence of variety classes, subsidiary factory is abundant.
Ozone oxidation method with the oxidation potential of ozone 2.7V, with organic matter reaction speed is fast, raw material is easy to get,Can produce on the spot, easy to use and do not produce the feature of secondary pollution, in the processing of dirty waste water, obtainFor application widely. But a unstability that subject matter is ozone itself of ozone oxidation method, meetingCause ozone oxidation section long operational time, the problem that treatment effeciency is low.
Photocatalysis is a kind of new method of oxidative degradation organic pollutants, have energy consumption low, easy and simple to handle,Reaction condition gentleness, reaction range be wide, can reduce the advantages such as secondary pollution. Photocatalysis method exist oneProblem is the dirty waste water for different light transmittances intuitively, and larger change can occur its light source range of effective radiationChanging, how to promote in other words the radiation efficiency of light source, is the key problem of photocatalysis method. In addition for lightCatalysis process, when it is applied separately, in the problem that has applicability aspect processing high-concentration industrial-water,Must coordinate the corresponding method for oxidation to set up corresponding Combined Processing mechanism, to promote whole catalytic oxidationEfficiency.
Metal catalytic is the main catalysis process of organic another kind in the water of oxidative degradation, metallic catalystCan impel ozone in water to decompose, produce the free radical with extremely strong oxidisability. What but the method was corresponding asksTopic is to exist the problem of secondary pollution, and according to the principle of total amount conservation, the metallic catalyst adding all can produceThe problem of raw corresponding metal ion pollution.
Current research and technique are all started with from method itself substantially, have ignored the important of flow field tissueProperty. Dirty wastewater treatment is all to realize in mobile environment, in the whole reactor of correspondence, howBy the good organization in flow field, fully improve the contact rate of dirty waste water and treatment process material, strengthening was reactedJourney is significant problem urgently to be resolved hurrily.
