Abstract
The invention relates to a sewage purifier preparation method and a purifier thereof and belongs to the field of oily sewage treatment of the petrochemical industry. Aiming at the problem that the existing treatment agent has few treatment effects, the invention provides the sewage purifier preparation method which has a relatively high treatment effect on oils and suspended matters and the purifier thereby. The method comprises the following step: obtaining a quaternary ammonium salt polymer (namely the sewage purifier) by ring opening polymerization of epoxy chloropropane and quaternization of chlorinated polyether. The purifier prepared by the method can be used for effectively removing sump oil and suspended matters out of sewage. The oil removal rate is over 90%, the suspended matter removal rate is over 80%, and the water purification effect is very remarkable.
Description
Technical field
The invention belongs to petrochemical industry oily water treatment field.
Background technology
Oilfield sewage mainly comprises the oily(waste)water that other type in water (having another name called oil field extracted water), drilling waste water and station deviate from by crude oil.The process of oilfield sewage can have various ways according to the factor such as field produces, environment, when oil field needs water filling, oilfield sewage is reinjection into reservoir after treatment, now strictly to control the suspended substance in water, wet goods many index, prevent its formation from producing injury, existing treatment agent, only better to a certain item effect, general to other mass treatment effect in water.
Summary of the invention
The object of this invention is to provide a kind of effluent purifier preparation method sump oil and suspended substance being had to preferred process effect.
The present invention is achieved by the following technical programs: a kind of effluent purifier preparation method, comprises the first step: the ring-opening polymerization of epoxy chloropropane, second step: chloro polyethers quaternary ammoniated;
In described first step, under catalyst action, take multi-alcohol as initiator, epoxy chloropropane drops in multi-alcohol and catalyst mixed liquid, and in adition process, temperature is 40 ~ 60 DEG C, is warmed up to 80 ~ 90 DEG C after adding,, be stirred to material homogeneous transparent, obtain chloro polyethers;
In described second step; chloro polyethers chloro polyethers and dimethylamine generation quaternary ammonium reaction, chloro polyethers mixes with dimethylamine agueous solution, under nitrogen atmosphere protection, carry out stir process; temperature is 60 ~ 80 DEG C; pressure 0.4MPa, is warming up to 100 ~ 120 DEG C after stirring reaction 5h gradually, continues to stir 4h; stopped reaction; be cooled to 40 DEG C, generate quaternary ammonium salt polymer, namely obtain described effluent purifier.
The present invention also provides a kind of water purification agent prepared by above-mentioned effluent purifier preparation method.
The present invention has following beneficial effect:
Adopt the water purification agent prepared of the method for the invention effectively can remove sump oil in sewage and suspended substance, oil removal rate can reach more than 90%.Removal efficiency can reach more than 80%, and purifying water effect is fairly obvious.
Embodiment
The present invention is described further by the following examples.
Specific embodiment: effluent purifier preparation method flow process of the present invention is as follows;
Under catalyst action, take multi-alcohol as initiator, epoxy chloropropane drops in multi-alcohol and catalyst mixed liquid, and in adition process, temperature is 40 ~ 60 DEG C, is warmed up to 80 ~ 90 DEG C after adding, be stirred to material homogeneous transparent, obtain chloro polyethers; Chloro polyethers chloro polyethers and dimethylamine generation quaternary ammonium reaction; chloro polyethers mixes with dimethylamine agueous solution; under nitrogen atmosphere protection, carry out stir process, temperature is 60 ~ 80 DEG C, pressure 0.4MPa; 100 ~ 120 DEG C are warming up to gradually after stirring reaction 5h; continue to stir 4h, stopped reaction, is cooled to 40 DEG C; generate quaternary ammonium salt polymer, namely obtain effluent purifier.
The effluent purifier obtained and other kind water purification agent are contrasted, get fresh sewage, recording initial concentration of oil is 196.12mg/L, and original suspension substrate concentration is 98mg/L, get the former water of 400mL and be placed in thermostat water bath, after adding appropriate water purification agent and coagulant aids HPAM, at the uniform velocity stir 1min, get clear liquid after standing sedimentation 30min and survey its oil concentration and concentration of suspension, HPAM add-on is 5mg/L, water temperature is 25 DEG C, and the settling time is 30min, and experimental result is as shown in the table.
As can be seen from above-mentioned experimental result can, existing water purification agent treatment effect is single, and the water purification agent water purification scope that the present invention obtains is wide, effective.
Effluent purifier preparation method and water purification agent thereof described in the embodiment of the present invention, have higher clearance to crude oil and suspended substance, oil removal rate reaches more than 90%, and removal efficiency reaches more than 80%, and purifying water effect is remarkable.
Above content is the further description done the present invention in conjunction with concrete embodiment, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, all should be considered as belonging to protection scope of the present invention.
