Description
Technical field
This application involves field of waste water treatment, in particular to a kind of wastewater treatment equipment and wastewater treatment method.
Background technology
With the fast development of pharmaceuticals industry, the pollution control problem of pharmacy waste water is more and more severeer.Pharmacy waste water belongs to
One of intractable industrial wastewater, because medicament categories are different, production technology is different, with component difference big, complicated components,
The features such as amount of pollutant is more, COD high, hard-degraded substance are more and strong toxicity.And the waste water in pharmaceutical factory is usually intermittent discharge, production
The type and quantity of product change greatly, and cause the type of the water quality of waste water, water and pollutant to change greatly, are brought to improvement
It is greatly difficult.General traditional stain disease treatment process has been unable to meet processing requirement of the today's society to pharmacy waste water.
Pharmaceuticals industry waste water mainly include antibiotic production wastewater, synthetic drug production waste water, Chinese patent medicine production wastewater with
And four major class of washings and flushing waste water of all kinds of formulation manufacturing processes.The characteristics of its waste water is complicated component, content of organics
It is high, toxicity is big, coloration depth and salt content are high, especially biochemical is very poor.
Existing pharmaceuticals industry wastewater treatment method has very much, but the effect handled is undesirable.
Traditional physical treatment method and chemical treatment method be for virose, Recalcitrant chemicals treatment effects
It is unconspicuous, seem the synthetic dyestuffs largely used in squeeze, spraying process, dyeing industry and food technology.And it is using
In the process, these toxic dyestuffs can also form some by-products under oxidation, hydroxylating or other chemical reactions effect,
Also threat is caused to the health of ecology and the mankind.
Conventional oxidation method handles pharmaceutical waste water, needs excessive high-valence state inorganic salts to make oxidant more, increases processing
Cost.
General electrochemical treatments technique can only the specific waste water of batch processed, treatment scale is small, and treatment effeciency is not high, and
And it is anode to mostly use metallic iron, as a result, bringing a large amount of molysite deposition.
Disclosed information above is used only to reinforce the background technology to technology described herein in the background section
Understanding may include therefore certain information in background technology, these information not formed to those skilled in the art
