Emit, drip, leak " various tank liquors and draining；(4) component cooling water, cooling water in use except temperature increase in addition to, not by
To pollution.Process conditions, produce load, operational administrative and the water use model etc. that water quality, water and the plating of electroplating wastewater produce
Factor is related.The water quality of electroplating wastewater is complicated, and ingredient is not easy to control.
Phosphorus removing method has very much, mainly on the market at present are as follows:
1, biochemical method, biochemical method organic phosphorus have more significant effect in processing waste water.But for electroplating wastewater,
The characteristics of due to its own, heavy metal contaminants are more, and water quality is complicated, and feasible robustness is poor, and bacterium is not easy to grow.If front-end processing
Waste strength is too high, and bacterium all dead can be cultivated again, so phosphor-removing effect is also not satisfactory.
2, chemical precipitation method, under alkaline condition, calcium ion can be formed with positive phosphorus and be precipitated, to effectively remove positive phosphorus.But
Phosphorus exists in the form of secondary phosphorus in electroplating wastewater, and hypophosphites solubility is high, it is more difficult to form precipitating, therefore can not also completely remove
Inorganic secondary phosphorus, in addition chemical precipitation method, will increase the volume for generating sludge, if can generate secondary dirt there are also investment medicament is excessive
Dye.
3, dephosphorization agent, a kind of dephosphorization process risen on the market.So-called dephosphorization agent quality is irregular, many kinds of,
Some are only preferable to simple water treatment effect, do not have specific aim for the waste water of complicated component, some are only to single
Index have removal effect, it is therefore necessary to do detailed selection, time-consuming, effort.
Therefore a kind of i.e. saving cost is developed, and electroplating wastewater processing efficiency can be improved, and the method for ideal treatment effect
It is very necessary.
