Description
Technical field:
The present invention relates to regenerated plastics processing technique fields, and in particular to regenerated plastics high concentration alkali water zero discharge handles work
Skill.
Background technique:
Recycled plastic granules are belonged in this scope of plastic grain, and regenerated plastics are then exactly that recycling is used new
The plastics that material or discarded plastics are produced by Luo bar machine, then a kind of granular plastics are cut by pelleter
Grain.Due to containing dust and greasy dirt etc. in salvage material, it is therefore desirable to be cleaned to plastic grain.Common buck carries out clear
It washes, but the sewage after cleaning, due to containing alkaline matter, environmental pollution is serious, therefore is unable to direct emission.And due to modeling
Expect that particle cleaning hourly water consumption is larger, if will directly clean the sewage discharge of a plastic grain, it will increase cleaning
With water cost.Current simplest sewage water treatment method be exactly the sludge for utilizing natural sedimentation, but being deposited in bottom be easy because
It seriously overstocks and is difficult to pump out, Treatment of Sludge is given to increase difficulty.
Summary of the invention:
It is a kind of by being incited somebody to action after separation suspension plastic grain and sludge technical problem to be solved by the present invention lies in providing
To clear water be re-used for down batch particle cleaning, save cleaning water consumption to play simultaneously and sewage neutral and alkali substance avoided to pollute
The regenerated plastics high concentration alkali water zero discharge treatment process of environment.
The following technical solution is employed for the technical problems to be solved by the invention to realize:
A kind of regenerated plastics high concentration alkali water zero discharge treatment process, including following operating procedure:

2 parts of glyceride, 1 part of Brazil wax, 0.5 part of gelatin, 0.5 part of C5 Petropols, 0.5 part of lanonol, 0.5 part of asbestos wool, stone
0.3 part of oil coke micro mist, 0.3 part of double trifluoromethanesulfonimides, preparation method are as follows: Brazil is added into hydrogenated rosin glyceride
Palm wax and gelatin, after being sufficiently mixed under microwave frequency 2450MHz, power 700W microwave treatment 5min, add C5 petroleum
Resin and petroleum coke micro mist, continue microwave treatment 5min after mixing, and gained mixture is transferred in 0-5 DEG C of environment immediately and seals
3h is stood, haloflex and lanonol is then added, and is heated to 120-130 DEG C of heat preservation mixing 10min, subsequent natural cooling
Microcrystalline cellulose, asbestos wool and double trifluoromethanesulfonimides, heat preservation mixing is added in cooling after temperature is down to 70-80 DEG C
10min, gained mixture are placed in sealing and standing 3h in -5-0 DEG C of environment, powder finally are made using micronizer.
2. regenerated plastics high concentration alkali water zero discharge treatment process according to claim 1, it is characterised in that: the reunion
The dosage of agent is that the alkaline sewage after every liter of plastic grain cleaning uses 0.05-0.1g.
3. regenerated plastics high concentration alkali water zero discharge treatment process according to claim 1, it is characterised in that: the gelatin
Pass through modification, processing method using preceding are as follows: 0.5 part of hydrogenated palm oil and 0.5 part of vulcanization pig are added into 15 parts of gelatin
Oil, after being sufficiently mixed under microwave frequency 2450MHz, power 700W microwave treatment 5min, stand microwave treatment again after 30min
Then 0.5 part of silicone emulsion and 0.3 part of polyvinyl butyral is added in 3min, after mixing microwave treatment 5min again, institute
It obtains mixture and is placed in sealing and standing 3h in -5-0 DEG C of environment, powder finally is made using micronizer.
