Description
Technical field
The present invention relates to technology of waste water control field, it is specifically related to a kind of water treatment microbe immobilized particles and its preparation method.
Background technology
China's shortage of water resources, spatial distribution is unbalanced, in recent years along with the rapid growth of China's economy and the fast development of industrial or agricultural, the demand of underground water is increasingly risen. Meanwhile, the trade effluent of a large amount of discharge, agricultural pollutant, municipal effluent and domestic waste become the major source causing groundwater pollution.
Groundwater pollution is complicated gradually, and the Composite pollution source that physics, chemical property are different moves to waterbearing stratum, or pollution plumage of different nature is overlapping in underground water, forms the Composite pollution plumage differed from one another. China was from 2006, whole nation underground water water resources investigation work is preferentially launched successively in developed area, the inorganic pollutant of detection take nitrate as representative, volatile organic matter is taking hydrochloric ether and benzene series thing as representative, the phenomenon that coexists multiple pollutant becomes clear day by day, and the situation of pollutent Individual existence is comparatively rare.
The health of the mankind can be caused serious injury by nitrate excessive in tap water, it is easy to cause dizziness, feel sick, heartbeat acceleration, the symptom such as diarrhoea. When nitrate is reduced into nitrite in human body, it is possible to cause methemoglobinemia, and bring out cancer. And multiple hydrochloric ether has been classified as priority acccess control compound by U.S. environment protection general administration, and studied confirmation can be carcinogenic, seriously affects human health.
The minimizing technology of groundwater pollutant can be divided into biological process, chemical method and physics method by present stage. For Composite pollution source, compared to physico-chemical process, such as stripping, absorption, ion-exchange, reverse osmosis, electrodialysis etc., biological process have processing cost low, process effective, process stabilization, be easy to operate and to the clear superiority of environment non-secondary pollution. Wherein, immobilized microorganism technology, because it has raising thalline utilization ratio, simplify processes technique, improves and the advantage of hardly degraded organic substance processing efficiency extensively favored. But, in conventional immobilized microorganism technology, there is the problem that immobilization particle work-ing life is short, repeating utilization factor is low, therefore, seek more mature and stable microorganism immobilization method, promote it more deep and apply widely in groundwater pollution process, become the problem needing solution at present badly.
Summary of the invention
