Description
Technical field
The utility model belongs to technical field of water treatment equipment, and in particular to it is a kind of it is compact-sized, at low cost, efficient,
The adaptable photocatalysis filler rod for sewage disposal.
Background technology
Environmental protection be related to human kind sustainable development important topic and scientific circles and industrial circle pay close attention to for a long time
One of focal issue.Water is the extremely valuable resource of nature, is the source of human life.With the high speed development of social economy
With the quickening of Process of Urbanization Construction, problem of environmental pollution, particularly water pollution are on the rise.Water pollution approach mainly has three aspects：
Industrial production wastewater；Sanitary sewage and agricultural production sewage.Wherein discharged volume of industrial waste water is big, and pollutant is numerous, and most of
With organic concentration height, biological degradability difference even has the features such as bio-toxicity；With the level of urbanization and people's life water
Flat quick raising, sanitary sewage sharply increase, it enters human body by all means, damage the health of people；Agriculture distributing
Production structure, pesticide and chemical fertilizer is caused to form the pollution rich in organic matter or even bio-toxicity to agricultural water.At present, it handles
The universal means of sewage are flocculation, electro-deposition, UF membrane, physical absorption, photochemical treatment, microbial degradation etc., but these sides
Method shortcoming is apparent, such as widely used flocculation is poor for dissolved organic matter in sewage and inorganic ions effect, needs
To pass through subsequent processing could remove；And UF membrane, physical absorption are mainly to be isolated from organic sewage by the method detached
Go out organic matter, this can bring secondary pollution；In addition, photochemical treatment is passed through organic sewage using ozone or hydrogen peroxide etc., profit
Degradation reaction is carried out with ultraviolet light, and the use of a large amount of ozone or hydrogen peroxide improves degradation cost, and excessive dioxygen

More photochemical catalyst nano coating device is wanted, and equipment holistic cost can be caused higher；In addition, photocatalysis sewage processing is general
Using the titanium dioxide optical catalyst of low cost, but since various photochemical catalysts are different to the treatment effect of different pollutants,
The equipment of the titanium dioxide optical catalyst of such as coating type or some other photochemical catalyst, since coating and technique limit, often
Cause the application limitation of sewage disposal, it is difficult to which, according to the difference of major pollutants in sewage, specific aim adjusts different photocatalysis
Agent is to improve treatment effeciency.Therefore, the problem of being handled for current photocatalysis sewage provides a kind of at low cost, processing
Photocatalysis apparatus efficient, adaptability is eager to do well in everything, has great importance.
