The invention discloses an efficient sewage treatment agent based on xanthan gum and a preparation method thereof. The efficient sewage treatment agent is prepared from xanthan gum, zeolite powder, palygorskite, aluminum oxide, sodium silicate, activated carbon, carboxymethylcellulose, starch, calcium oxide, potassium persulfate, oxethyl siloxane and polyethylene glycol. After the xanthan gum and polyethylene glycol are dissolved, the materials are mixed with the xanthan gum, palygorskite and carboxymethylcellulose, then the zeolite powder, sodium silicate, the activate carbon and oxethyl siloxane are added, and the materials are mixed to be uniform; after calcium oxide is added and dissolved, a water solution is obtained and reacts with aluminum oxide, the product is mixed with starch and potassium persulfate after being treated, drying is carried out, and the efficient sewage treatment agent can be obtained. One of the main raw materials of the sewage treatment agent is the xanthan gum, cost is low, the source is wide, and the raw materials are easy to obtain. The preparation process is simple, the efficient sewage treatment agent is applied to treating urban sanitary sewage and industrial waste water, the index of the treated waste water is far lower than the national standard, and a very obvious effect is achieved in the intermediate treatment process of the sewage.
Description
Technical field
The present invention relates to sewage treatment area, specifically a kind of high efficiency sewage treating agent based on xanthan gum and its preparation side
Method.
Background technology
Environmental conservation directly affects the sustainable development of Chinese national economy.Economic development in China's the past few decades
In, due to ignoring developing environmental conservation, result in the extremely serious situation of environmental pollution at this stage.Though took in recent years big
The control measure of amount, but the trend that environment is deteriorated further is still continuing.In the annual sewage discharge in the whole nation, only 10% life dirt
Water and 70% trade effluent are processed, and wherein be there are about the water outlet of half Industrial Waste Water Treatments facility and do not reached national discharge
Standard, remaining untreated sewage is then directly discharged in rivers and lakes, causes the water environment of China to be subject to severe contamination and break
Bad；The discharge capacity of cities and towns and city domestic sewage is just in incremental trend with city-building and development, and in further
The trend of deterioration, about 50% urban groundwater is polluted by different degrees of, causes serious harm to people's health.
China's urban sewage treatment process generally uses traditional activated sludge process, oxidation ditch, SBR etc. at present, 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
The construction of municipal sewage plant of China is hindered, while the reason for some sewage treatment plants for building up are also because of high energy consumption, long-term is located
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 sewage disposal is solved the problems, such as, reduce processing cost and optimization process, be current all Sewage Plant institutes face
The common issue that faces；And the selection for sewage-treating agent is also always one of emphasis.
Although existing sewage-treating agent has met existing needs, the raw material of these sewage-treating agents need into
Row is produced for second, its cost height, and the energy consumption for producing is also larger, always cannot to the cost of many sewage treatment plants
Effectively reduce.
Content of the invention
It is an object of the invention to provide a kind of high efficiency sewage treating agent based on xanthan gum and preparation method thereof, to solve
The problem for proposing in above-mentioned background technology.

And 4～6h is stirred, film forming being spread out after cooling, carry out second crushing after drying, crosses 380～420 mesh sieves, obtain mixed-powder A；
(3) mixed-powder A is added in the water of 8～10 times of its gross weight, 230～250 DEG C is heated to, sequentially adds zeolite
Powder, sodium silicate, activated carbon and ethoxy radical siloxane, stir 10～12h, while supersound process is carried out, after mix homogeneously, will be mixed
Closing liquid and spread film forming out, third time crushing is carried out after drying, and crosses 400～440 mesh sieves, obtain mixed powder B；
(4) calcium oxide is added in the water of 4～6 times of its weight, slow latex mixed powder B, stirs while adding, stirring
Uniformly, aluminium oxide is then slowly added into, then proceedes to stir 2～3h, heating is concentrated into thick paste, be subsequently placed in 30～40 DEG C dry
It is dried in dry case, the 4th crushing is carried out, 400～440 mesh sieves is crossed, obtains mixed-powder C；
(5) starch, potassium peroxydisulfate are added in mixed-powder C by proportioning, mix homogeneously, drying at 30～36 DEG C is
Can.
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 xanthan
Glue, not only low cost, wide material sources, and other raw materials are all adopted mostly with common natural material, are readily obtained, and are become
This low, preparation process is simple of the present invention, will apply which to process the sanitary sewage in city and industrial wastewater, the waste water after process
Index obtains fairly obvious effect well below national standard during the intermediate treatment of sewage.
