Description
Technical field
It is specifically a kind of to be based on bentonitic composite highly effective sewage-treating agent the present invention relates to sewage treatment area.
Background technology
Environmental protection 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 protection, 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 is then directly discharged into rivers and lakes, causes the water environment of China to be subject to severe contamination and break
It is bad；The discharge capacity of town domestic sewage is just in incremental trend with city-building with developing, and urban ground water pollution is universal
Seriously, and in the further trend for deteriorating, about 50% urban groundwater is polluted by different degrees of, people's health is caused
Serious harm.
Current China urban sewage treatment process generally uses traditional activated sludge process, oxidation ditch, SBR etc., these
Ripe and effective handling process, is widely used in various regions.But for a long period, hindered 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, long-term place
In stopping production and half end-of-life state.Within one considerably long from now on period, energy consumption problem will turn into 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 be also always one of emphasis for the selection of sewage-treating agent.Although existing sewage-treating agent is
Meet it is existing the need for, but the raw material of these sewage-treating agents is in short supply, its cost is high, and production energy consumption also compared with
Greatly, the cost to many sewage treatment plants cannot be effectively reduced always.
The content of the invention
Bentonitic composite highly effective sewage-treating agent is based on it is an object of the invention to provide one kind, to solve above-mentioned background
The problem proposed in technology.
To achieve the above object, the present invention provides following technical scheme：
One kind is based on bentonitic composite highly effective sewage-treating agent, is prepared from by the raw material of following weight portion：Bentonite

14~16 parts of zinc, 8~10 parts of potassium permanganate.
A kind of described preparation method based on bentonitic composite highly effective sewage-treating agent, specific preparation process is as follows：
(1) bentonite is cleaned and is dried, carry out being melt into block after smashing, carried out respectively with attapulgite clay, polyethylene glycol
Crush, cross 380~420 mesh sieves, obtain corresponding powder, it is standby；
(2) polyethylene glycol powder is added in the water of 10~12 times of its gross weight, is heated to 95~100 DEG C, stirred
To transparent solution, bentonite powder, attapulgite clay powder are then sequentially added, be heated to 250~300 DEG C, and stir 4~
6h, spreads film forming out after cooling, second crushing is carried out 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, is heated to 230~250 DEG C, sequentially add quartz
Stone, alum, zinc acetate and urea, stir 10~12h, while carry out it is ultrasonically treated, be well mixed after, mixed liquor is spread out into
Film, carries out third time crushing after drying, and crosses 400~440 mesh sieves, obtains mixed powder B；
(4) zinc sulfate is added to the water, and is diluted, be slowly mixed together powder B, stirred, be slow added into oxidation
Magnesium, stirs while adding, to be precipitated to finish, and is filtered to remove supernatant, then is placed in 30~40 DEG C of drying box by precipitation
Row drying, carries out the 4th crushing, crosses 400~440 mesh sieves, obtains mixed-powder C；
(5) in crushed crude pearlite, starch, potassium permanganate being added into mixed-powder C by proportioning, it is well mixed, at 30~36 DEG C
Lower drying.
Compared with prior art, the beneficial effects of the invention are as follows：One of main material of sewage-treating agent of the present invention is swelling
Soil, not only low cost, wide material sources, and other raw materials are also readily available, and low cost, preparation technology letter of the invention
