The great reason of water environment degradation, therefore, industrial water pollution preventing and treating is also one of emphasis of China environmental protection.
Industrial wastewater is the main source of pollutant, has agricultural, social environment, natural environment and health of people seriously
Harm, be industrial wastewater to be most difficult to process one of waste water containing organic matter and heavy metal wastewater thereby, there is technique in current processing method
The defects such as complexity, cost of investment are high, floor space is big, treatment effeciency is not ideal.
Summary of the invention
It is difficult to improvement up to standard for the method administering industrial wastewater at present, or operation operating cost height, ton water harnessing is costly,
Or the shortcoming such as floor space is big, the present invention provides a kind of absorption-oxidation to administer the three-phase fluid bed reactor of industrial wastewater, uses
In waste water treatment, improve harmful substance clearance, reduce resource consumption, improve recycling economy, non-secondary pollution,
There is floor space few (than advantages such as conventional biochemical process Economization on land 60-90%.
For solving above-mentioned technical problem, the technical solution adopted in the present invention is as follows:
