Description
Technical field
The present invention relates to a kind of coagulant suitable for coking wastewater processing system.
Background technology
Coking chemical waste water is a kind of typical poisonous organic wastewater with difficult degradation thereby, essentially from coke oven gas primary-cooling and coking production
During industrial water and steam condensation waste water.Its composition is sufficiently complex, contains volatile phenol, biphenyl, pyridine and quinoline
Etc. being difficult to the compounds such as biodegradable aromatic series organic matter, polycyclic compound and oxygen sulphur nitrogen.Pollutant concentration in coking chemical waste water
It is high, it is difficult to degrade, due to the presence of nitrogen in coking chemical waste water, cause the nitrogen source needed for biological cleaning superfluous, to handling up to standard bring
Larger difficulty.
Flocculence, it is to use a kind of more universal water process mode both at home and abroad due to its simple process, economy.It is conventional
Flocculant, as aluminium polychloride, poly-ferric chloride, polyaluminium sulfate, bodied ferric sulfate, aluminum sulfate, ferric sulfate, aluminium chloride and
Iron chloride etc..During coking chemical waste water coagulating kinetics, there is the part that has much room for improvement in traditional coagulant：Such as sulfuric acid
Aluminium, when water temperature is low, hydrolysis is difficult for it, and loosely, coagulation effect is deteriorated the floccule body of formation, and rough aluminum sulfate is due to insoluble
Property impurity content it is high, waste residue is more during use, and acidity is higher, and corrosivity is stronger；Ferric trichloride, solid product easily absorb water tide
Solution, is not easy to take care of, and corrosivity is stronger, and it is narrower most preferably to add scope, is difficult to control；Aluminium polychloride, because by raw material, process conditions
Deng limitation, quality can be affected, and each department lack the special producer with replenishment of process.
The content of the invention
The invention aims to overcome the weak point in prior art, there is provided one kind is applied to Treatment of Coking Effluent
The coagulant of system, poor to solve coagulation effect, COD clearances are low, the stronger problem of corrosivity.
In order to achieve the above object, the present invention uses following scheme：
A kind of coagulant suitable for coking wastewater processing system, it is characterised in that described including inorganic flocculating agent and flocculation aid
Inorganic flocculating agent includes amine macromolecule, Polyferric Sulfate Flocculants（Ferric ion）, polysilicate, ferrous ion and
Other rare earth metals, the flocculation aid include PAMA.
In one or more embodiments, its each composition accounting is：Amine high polymer coagulant 0.8%-1%, polymerised sulphur
Sour iron（Ferric ion）11%-13%, polysilicate 1 ‰, ferrous ion 5 ‰ -10 ‰, other rare earth metals 0.1 ‰ -
0.2 ‰, flocculation aid PAMA（Molecular weight 18,000,000, degree of hydrolysis 13%）.
In one or more embodiments, its described dosage is 0.3 ‰ -1.2 ‰.
Beneficial effect：The present invention provides the coagulant suitable for coking wastewater processing system to coking water treatment effect
It is good, to the COD clearances of coking chemical waste water up to more than 80%, to the clearance of colourity more than 99%；Oil removing, remove turbidity,
It is also more notable on heavy metal and the effect of part ammonia nitrogen and phosphorus.
Embodiment
Application scheme is further described：
