Description
Technical field
The present invention relates to sewage treatment area, specifically a kind of composite highly effective sewage-treating agent based on waste plastic and its
Preparation method.
Background technology
Environmental protection directly affects the sustainable development of Chinese national economy.Economic development in China's the past few decades
In, due to ignoring developing environmental protection, result in the extremely serious situation of environmental pollution at this stage.Though taking big in recent years
The control measure of amount, but the trend that environment deteriorates further is still continuing.China is the state the most serious of environmental pollution in the world
One of family.In the annual sewage discharge in the whole nation, only 10% sanitary sewage and 70% trade effluent are processed, and wherein there are about
The water outlet of half Industrial Waste Water Treatments facility does not reach discharging standards, and remaining untreated sewage is then directly discharged into rivers lake
In pool, the water environment of China is caused to be subject to severe contamination and destruction；The discharge capacity of town domestic sewage is just with city-building
With development and be in incremental trend, urban ground water pollution is generally serious, and in the trend deteriorating further, about 50% city
Underground water is subject to different degrees of polluting, and causes serious harm to people's health；Various plastic garbages be flooded with city, cities and towns with
And rural area, in aerial, ground, water and underground all exists, because a lot of plastics are all nondecomposable, this undoubtedly give environment,
Animals and plants and the mankind bring great harm.
That China's urban sewage treatment process is commonly used at present is traditional activated sludge process, oxidation ditch, sbr etc., these
Ripe and effective handling process, is widely used in various places.But for a long period, hinder because energy consumption is big, operating cost is high
Hinder the construction of municipal sewage plant of China, the reason the sewage treatment plant more simultaneously building up is also because of high energy consumption, long-term locate
In stopping production and half end-of-life state.Within one considerably long from now on period, energy consumption problem will become the bottleneck of municipal sewage treatment.
Therefore, on solving the problems, such as sewage disposal, reduce processing cost and optimization process, be current all Sewage Plant institutes face
The common issue faced；And the selection for sewage-treating agent is also always one of emphasis.Although existing sewage-treating agent is
Meet existing needs, but the raw material of these sewage-treating agents is in short supply, its cost is high, and the energy consumption producing is also relatively
Greatly, the cost to many sewage treatment plants cannot effectively reduce always.
Content of the invention
It is an object of the invention to provide a kind of composite highly effective sewage-treating agent based on waste plastic and preparation method thereof,
To solve the problems, such as to propose in above-mentioned background technology.
For achieving the above object, the following technical scheme of present invention offer:
A kind of composite highly effective sewage-treating agent based on waste plastic, is prepared from by the raw material of following weight portion: discarded
120～140 parts of plastics, 60～80 parts of graphite, 19～21 parts of rock phosphate in powder, 22～24 parts of alum, 17～19 parts of acetic acid, bamboo charcoal powder 40
～60 parts, 30～36 parts of calcium oxide, 13～15 parts of starch, 14～16 parts of polyacrylamide, 8～10 parts of sodium hypochlorite, urea 19
～23 parts, 100～120 parts of polyethylene glycol.
A kind of preparation method of the described composite highly effective sewage-treating agent based on waste plastic, concrete preparation process is such as
Under:
(1) waste plastic is cleaned and dry, carry out after smashing being melt into block, carry out powder respectively with rock phosphate in powder, polyethylene glycol
Broken, cross 380～420 mesh sieves, obtain corresponding powder, standby；
(2) polyethylene glycol powder is added in the water of 10～12 times of its gross weight, be heated to 95～100 DEG C, stir
To transparent solution, then sequentially add waste plastic powder, rock phosphate in powder powder, be heated to 250～300 DEG C, and stir 4～
6h, spreads film forming out after cooling, carries out second pulverizing after drying, and crosses 380～420 mesh sieves, obtains mixed-powder a；
(3) mixed-powder a is added in the water of 8～10 times of its gross weight, be heated to 230～250 DEG C, sequentially add stone
Ink, alum, polyacrylamide and urea, stir 10～12h, carry out ultrasonically treated simultaneously, after mixing, mixed liquor is spread out
It is split into film, carry out third time after drying and pulverize, and cross 400～440 mesh sieves, obtain mixed-powder b；
(4) acetic acid is diluted 6～8 times, is then mixed with mixed-powder b, be placed in closed container standing 4～
6h, is dried in the drying box being subsequently placed in 30～40 DEG C, carries out the 4th pulverizing, crosses 400～440 mesh sieves, mixed
Powder c；
(5) calcium oxide, bamboo charcoal powder, starch, sodium hypochlorite are pressed proportioning and added in mixed-powder c, mix, 30～
Dry at 36 DEG C.
Compared with prior art, the invention has the beneficial effects as follows: one of main material of sewage-treating agent of the present invention is discarded
Plastics, not only low cost, wide material sources, but also the recycling of resource can be realized, greatly reduce exhaust emission, and
Other raw materials are also readily available, and low cost, the preparation process is simple of the present invention, dirty by applying it to process the life in city
Water and industrial wastewater, the waste water index after process well below national standard, for the intermediate treatment process effect ten of sewage
Clearly show.
