Description
Technical field
The present invention relates to sewage treatment area, specifically a kind of sewage-treating agent based on xanthan gum and preparation method thereof.
Background technology
Environmental conservation directly affects the sustainable development of Chinese national economy.In the economic development of 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 big in recent years
The control measure of amount, but the trend that environment is further deteriorated is still in continuation.In national annual sewage discharge, only 10% life is dirty
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 are then directly discharged in rivers and lakes, cause the water environment of China to be subject to severe contamination and break
It is bad；The discharge capacity of cities and towns and city domestic sewage is just in incremental trend with developing with city-building, and in further
The trend of deterioration, about 50% urban groundwater are polluted by different degrees of, cause 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
Hinder the construction of municipal sewage plant of China, at the same some sewage treatment plants for building up also because of high energy consumption the reason for, it is long-term to 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 sewage disposal is solved the problems, such as, processing cost and optimization process are reduced, is current all Sewage Plant institutes face
The common issue faced；And for the selection of 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, and its cost is high, and the energy consumption for producing is also larger, always cannot to the cost of many sewage treatment plants
Effectively reduce.
The content of the invention
It is an object of the invention to provide a kind of sewage-treating agent based on xanthan gum and preparation method thereof, above-mentioned to solve
The problem proposed in background technology.
For achieving the above object, the present invention provides following technical scheme：
A kind of sewage-treating agent based on xanthan gum, is prepared from by the raw material of following weight portion：Xanthan gum 120～140

Part, 14～16 parts of calcium oxide, 8～10 parts of potassium peroxydisulfate.
A kind of preparation method of the described sewage-treating agent based on xanthan gum, concrete preparation process are as follows：
(1) Paligorskite, Polyethylene Glycol are crushed respectively, crosses 380～420 mesh sieves, obtain corresponding powder, it is standby；
(2), during polyethylene glycol powder to be added the water of 10～12 times of its gross weight, 95～100 DEG C are heated to, are stirred
To transparent solution, xanthan gum, Paligorskite powder and carboxymethyl cellulose are then sequentially added, 250～300 DEG C are heated to,
And 4～6h is stirred, spread film forming after cooling out, after drying, carry out second crushing, cross 380～420 mesh sieves, obtain mixed-powder A；
(3), during mixed-powder A to be added the water of 8～10 times of its gross weight, 230～250 DEG C is heated to, Hai Pao is sequentially added
Stone powder, sodium silicate, activated carbon and ethoxy radical siloxane, stir 10～12h, while supersound process is carried out, after mix homogeneously, will
Mixed liquor spreads film forming out, carries out third time crushing, and crosses 400～440 mesh sieves, obtain mixed powder B after drying；
(4) during calcium oxide to be added the water of 4～6 times of its weight, slow latex mixed powder B is stirred while adding, stirring
Uniformly, humic acid is then slowly added into, then proceedes to 2～3h of stirring, heating is concentrated into thick paste, be subsequently placed in 30～40 DEG C dry
It is dried in dry case, carries out the 4th crushing, cross 400～440 mesh sieves, obtain mixed-powder C；
(5) tapioca starch, potassium peroxydisulfate are added in mixed-powder C by proportioning, mix homogeneously, the 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 into
This is low, the preparation process is simple of the present invention, the sanitary sewage and industrial wastewater in city, the waste water after process will be processed using which
Index obtains fairly obvious effect during the intermediate treatment of sewage well below national standard.
