Description
Technical field
The present invention relates to technical field of sewage, specifically a kind of Industrial Wastewater Treatment coagulant and its making side
Method.
Background technology
Coagulant is mainly used in purification and the industrial wastewater of Drinking Water, the process of special water quality（As oil-polluted water, print
Dye papermaking wastewater, smelting sewage, speciality containing radioactivity, containing the toxic heavy metals such as Pb, Cr and sewage containing F etc.）.In addition in accurate casting
Make, oil drilling, process hides, the aspect such as metallurgical papermaking also have extensive use.
Coagulant refers in water treatment procedure colloidal particles in water can mutually to bond and to flock together
Chemical agent, in waste water control, conventional coagulant substantially can be divided three classes：Organic coagulants, inorganic coagulant and macromolecule
Coagulant.Wherein inorganic salts coagulant applies relatively universal, mainly water miscible two valencys or trivalent metal salt in water process,
As iron salt and aluminium salt and its hydrating polymer.The inorganic salts coagulant that can select has aluminum sulfate, ferric chloride, sulphuric acid sub-
Ferrum, aluminium potassium sulfate（Alumen）, sodium aluminate and iron sulfate etc..
Aluminum sulfate makees coagulant convenient transportation, simple to operate, and coagulation effect is good, but when water temperature is low, aluminum sulfate hydrolysis are difficult,
Loosely, coagulation effect is deteriorated the floccule body being formed；And if use when add excess sulfuric acid aluminum, the pH value of water can be made to be down to aluminium salt
Below coagulation effective pH value, both wasted medicament, made the water clouding after process again.Rough aluminum sulfate is due to insoluble impuritiess content
Height, during use, waste residue is more, brings the troublesome poeration of exclusion waste residue aspect, and corrosivity are stronger because acidity is higher, dissolving
With adding equipment should be noted anti-corrosion.
It is soluble that ferric chloride does its advantage of coagulant, and the floccule body of formation is more closely knit than Alhumic flocs, sedimentation velocity
Hurry up, when processing low temperature, low-cloudy water, effect is better than aluminum sulfate, applicable pH value range is wider, and dosage is less than aluminum sulfate；Its shortcoming
It is that ferric chloride solid product easily absorbs water deliquescence, is difficult keeping, corrosivity are stronger, all have corruption to metal, concrete, plastics etc.
Corrosion, after process, colourity processes than aluminium salt that water is high, and it is narrower most preferably to add scope, wayward etc..
