Abstract
The invention provides a kind of cation coagulant, belong to sewage, wastewater treatment scavenging agent; It is a kind of organic composite type cationic flocculant.
It is by H
2N (CH
2CH
2NH-)
DH and epichlorohydrin make the cationic flocculant polycaprolactam polyamine, hybridize composite mixture with it with salt again.This flocculation agent and conventional dose compare as polymerize aluminum chloride (poly-aluminium), bodied ferric sulfate (poly-iron) etc. that to have a consumption low, and flocculation settling velocity is fast, supernatant water transparency height, and advantage such as floc sedimentation sediment filterableness is good, it also can be used as flocculating aids.Can be widely used in the wastewater treatment of colliery well water, coal separating plant's black water and industries such as petrochemical complex, papermaking, process hides and printing and dyeing.
Description
The present invention relates to a kind of chemical substance, especially a kind of waste water, sewage disposal scavenging agent.
At present, the discharging of various wastewater and sewage has caused severe contamination to environment in industrial production, brings detrimentally affect also for people's life and health.But to pit water, coal separating plant's black water and petrochemical wastewater, paper waste, leather-making waste water, waste water such as printing and dyeing, in the improvement of sewage, widespread use polyacrylamide flocculation agent, or polyacrylamide flocculation agent and other medicament such as polymerize aluminum chloride, poly-ferric chlorides etc. are united use, it has certain effect evidence, as " PFS flocculation agent and black water are handled " (seeing the coal preparation technology fourth phase in 1987), it is a bodied ferric sulfate, be called for short " poly-iron ", it has obtained certain effect in pit water and black water processing, but it only to rare (1.5g/l) pit water of concentration or (30g/l) black water handle effectively, not good for black water or other wastewater treatment efficiency that the thin mud of high density is many, or dosing is very big, or it is clear to be that usage quantity greatly also can not get water; The floc sedimentation settling velocity is slow, needs 30 minutes just to drop to 16 ° when the sewage turbidity is 100 °; Raw material and product are acid big, and be strong to equipment corrosion.And for example " the selective flocculation method purifies the research and the application of tail coal water " (see coal mine environment protected for the 6th the 2nd phase of volume), it is only to use polyacrylamide, or the method that cooperates with Tai-Ace S 150 with polyacrylamide, though especially latter's flocculating effect increases, but also exist flocculation back supernatant water solid content (2g/l) higher, clarity is not enough; The slow (～shortcoming such as 0.60mm/s) of floc sedimentation settling velocity.Because they all are the single component flocculation agents, and powder performance is single, or has only cohesion, or has only throwing out, can not adapt to the needs of black water (waste water) processing of various different in kinds again, effect is not ideal enough; Especially to some unmanageable black water (waste water), use these medicaments to can not get clear water, promptly water quality does not reach emission standard at all, can not round-robin, and a large amount of waste water of coal separating plant (factory) are effluxed, environment is caused severe contamination, and waste water resource.
The objective of the invention is to develop a kind of new and effective cationic flocculant in order to overcome above-mentioned weak point of the prior art, it can use separately or unite use with polyacrylamide, can make high density, black water (waste water) flocculation settling velocity that thin mud is many is fast, the supernatant water turbidity is low, as clear as crystal, floc sedimentation sediment strainability is good.
Task of the present invention realizes that as follows it is by H
2N(-CH
2CH
2NH-)
DH and 3-chloro-1.2-propylene oxide make cationic flocculant under certain condition and gather-the beta-hydroxy polyamines, are called for short polycaprolactam polyamine.
Its structural formula:
Its reaction is undertaken by following method, with A, B and E(water) in reactor, heat, temperature remains on 80～110 ℃, and be incubated discharging in 4～6 hours, obtain water-soluble chain macromolecule compound polycaprolactam polyamine, hybridize compositely again with it and C, make the organic composite type cationic flocculant.Wherein (A) is polyethylene polyamine H
2N(-CH
2CH
2NH-)
DH(B) be MX(D for 3-chloro-1.2-propylene oxide (C)) be 1,2,3,4,5 ... (M) be two, trivalent metal ion, (X) be one, the divalence acid group.Each amount of substance (mole or weight) is in following ratio: sA: tB: uAB: vE: wC.sA∶tB;uAB∶vE∶wC。S: t=1 wherein: 1,1: 1.2,1: 1.5,1: 2.0; U: v: w=1: 10: 6,1: 9: 10,1: 14: 10,1: 29: 10.
The present invention has following advantage compared with prior art: (1) the present invention is than conventional medicament such as polymerize aluminum chloride, and bodied ferric sulfate, Tai-Ace S 150 etc. are united use with polypropylene amine flocculation agent, and dosing is few, thereby reduces wastewater treatment expense 20～30%; (2) excellent wastewater treatment effect, the floc sedimentation settling velocity is fast, and the supernatant water turbidity is low, and is as clear as crystal, makes waste water reclamation multiplexing, the conserve water resource.Concerning coal separating plant, have more significance, can improve washing and flotation effect widely, improved economic benefit; (3) strainability of its floc sedimentation, sediment is good, and concerning coal separating plant, coal slime all reclaims in the factory, and is both energy-conservation, and enabling environment protection again benefits the society; (4) little to equipment corrosion, reduce maintenance of equipment, reduce cost; (5) the present invention is a multipurpose agent, and its existing cohesion has flocculating property again, also has filtrating aid function in addition, so can be used as flocculating aids again.
Embodiments of the invention are as follows: with 146 parts of H
2N(-CH
