Since nearly ten years, because former oil product material changes and the raising of the level of crude oil processing, the water quality of sewage from oil refinery worsens day by day, and the situation that sewage disposal faces is severe day by day, and the effect that improves present sewage disposal is imperative.Because the waste water of refining of petroleum discharging mainly contains dispersed oil and oil in water emulsion, because of in the process of using oil or treated oil, often added certain auxiliary agent, also contain clean-out system, emulsifying agent one class tensio-active agent in oily(waste)water, the existence of these auxiliary agents brings certain difficulty for the improvement of oily(waste)water.There is electrostatic double layer in the oil in water emulsion surface or is subjected to emulsifying agent protection and exists with stable status for a long time, carries negative charge, makes sewage disposal comparatively complicated, and in recent years, positive ion organic high polymer coagulant was extremely paid attention in oily water treatment.
In present technology, positive ion organic high polymer coagulant mainly contains:
1, with the condensation polymer of diamine (or monoamine) with dihalide or epoxy chloropropane.For example, can be used as the flocculation agent of handling oily(waste)water by hexanediamine, quadrol and the polymkeric substance of 1.4 2 chloro-, 2 butylene and the compound that mixes of Virahol and zinc chloride; 1.4 two chloro-, 2 butylene and dimethylamine, carry out condensation reaction having in the presence of (or do not have) quadrol, resulting polymers is 5.5 o'clock at PH, the said products solution of use 35-80mg/L, and cooperate aluminium salt and polyacrylamide, also can be used as the flocculation agent of handling oily(waste)water.
2, epoxy chloropropane and dimethylamine and polyamines (Diethylenetriamine) act on the polymkeric substance of the quaternary amine type that makes, and its molecular weight reaches more than 10000, can be effective to the breakdown of emulsion of oily(waste)water.The reaction product of hexanediamine, propylene oxide and the polymkeric substance of epoxy chloropropane, with zinc chloride, aluminum chloride or ferric sulfate are composite, can be used as the flocculation agent of handling oily(waste)water.
3, Mannich (mannich) alkali of being made up of polyacrylamide and dimethylamine, formaldehyde is quaternized through methyl chloride or methyl-sulfate, in conjunction with aluminium salt, can be used as the flocculation agent of handling oily(waste)water.
The positive ion organic high polymer coagulant of the above-mentioned type all will be prepared inorganics in handling the oily(waste)water process, could obtain effect preferably, and the adding of inorganics has brought the problem of equipment corrosion and blocking pipe; Its add-on just has suitable effect when 15mg/L is above, add-on is big, and the scum silica frost of generation is many, " three mud " processing costs height, shortcoming such as secondary pollution is big.
