Description
Technical field
The present invention relates to a kind of water treatment agent, specifically a kind of ground surface eutrophic water inorganic agent and preparation method thereof.
Background technique
Eutrophication is a kind of excessive caused water pollution phenomenon of the plant nutrient substances contents such as nitrogen, phosphorus.In nature
Under the conditions of, alluvial deposits and aquatile remains are carried secretly with river and are deposited in the continuous sedimentation of lakebed, and lake can be from flat nutrition lake
Transition is eutrophic lake, and then develops into marsh and land, this is a kind of extremely slow process.But due to the activity of the mankind,
Plant nutrient substance in a large amount of industrial wastewaters and sanitary sewage and agricultural run-off is discharged into lake, reservoir, river mouth, bay etc.
After slow flow water bodies, mass propagation is made the population number of species of biomass change, destroyed by aquatile especially algae
The ecological balance of water body.The index of eutrophication generally uses: the content of Water is more than 0.2~0.33ppm, and phosphorus content is big
In 0.01~0.02ppm, biochemical oxygen demand (BOD) is greater than 10ppm, in the fresh water of pH value 7~9 every milliliter of total number of bacteria more than 100,000,
The chlorophyll-a content for characterizing amount of algae is greater than 10 mg/litres.
The development trend in China lake, reservoir and rivers eutrophication is very fast.1978~1980 years most of lakes
In middle nutritional status, the 91.8% of investigation area is accounted for, lean nutritional status lake accounts for 3.2%, and eutrophic state lake accounts for
5.0%.Between short 10 years, the big multidirectional middle nutritional status lake transition in lean nutritional status lake, lean nutritional status is commented shared by lake
Valence area ratio is rapidly decreased to 0.53% from 3.2%, and middle nutritional status lake is to eutrophic state transition, eutrophic lake
Shared evaluation area ratio increases severely from 5.0% to 55.01%.Wuhan Han River downstream water quality sharply deteriorates in the past 10 years, is in Fu Ying
Feedingization state, in once 2 " wawter bloom " phenomenons for Measures of Algae in Water Body occur and sharply breeding the 1990s.
Mainly have for the control measures of eutrophication water at present: one, microorganism treatment, it is suitable micro- by adding
Biology accelerates the decomposition of water pollutant, plays the role of purification of water quality；Two, flocculation treatment method, being added has flocculation
Phosphate in flocculant, with water body generates infusible precipitate, achievees the purpose that reduce phosphorus content；Three, water plant cultivation method,
Nitrogen and phosphorus element is absorbed and utilized using water plant and carries out metabolic activity to remove the nutriments such as the nitrogen in water body, phosphorus.Flocculence
With easy to use, the advantages of will not causing secondary pollution, be the control measures of main eutrophication water.Therefore, it studies
The sewage-treating agent of one kind of multiple functions is extremely urgent.
Summary of the invention
Earth's surface eutrophication water inorganic agent and preparation method thereof is used the purpose of the present invention is to provide a kind of, on solving
State the problem of proposing in background technique.
To achieve the above object, the invention provides the following technical scheme:

75 parts, 8-30 parts of bacillus powder, 5-30 parts of desulfurization bacterium powder.
Further, the raw material of the plant source charcoal includes corn stover, cotton stalk, soybean stalk, sesame straw
One or more of stalk, Poplar Powder, ash powder, bamboo powder and walnut shell.
A kind of preparation method of ground surface eutrophic water body inorganic agent, comprising the following steps:
A. the preparation of modified oyster: oyster shell is cleaned repeatedly with deionized water, is sieved with 100 mesh sieve after 105 DEG C of drying grindings, and
Modified oyster is prepared using former oyster shell powder as raw material, using limit oxygen heating charring in electricity at a temperature of 250-800 DEG C
Pyrolysis 1h makes its modification in solution furnace, after natural cooling, is stored in spare in drier；
B. the preparation of plant source charcoal: Poplar Powder, ash powder, bamboo powder using purchase are raw material, using limit oxygen heating charing
After method warms naturally to 450-550 DEG C of pyrolysis 3h in electrolytic furnace, it is made wood powder charcoal and bamboo powder charcoal, after natural cooling
It sieves with 100 mesh sieve, is stored in spare in drier；
C. the preparation of vermiculite: the vermiculite of purchase sieves with 100 mesh sieve, and is stored in spare in drier；
D. Concave-convex clay rod, activated bentonite are activated: will be containing the uniformly sprinkling respectively of the sulfuric acid solution of weight percent 6~12%
It on Concave-convex clay rod, bentonite, stirs evenly, is aged 4~8h, is stored in spare in drier；
E. by modified oyster, plant source charcoal, vermiculite, activation Concave-convex clay rod, activated bentonite, bacillus powder,
Desulfurization bacterium powder is uniformly mixed to get eutrophication water inorganic agent, and the total amount of addition is the 0.012- of black and odorous water gross mass
0.02%.
Preferably, the calcination temperature of oyster shell is 660 DEG C in the step a.
Preferably, the calcination temperature of oyster shell is 500 DEG C in the step a.
Preferably, the calcination temperature of oyster shell is 260 DEG C in the step a.
The beneficial effects of the present invention are:
(1) water quality in ground surface eutrophic water body can be changed in a short time using inorganic agent of the invention, reached
Surface water IV class standard or more makes the water body base of eutrophication due to thorough to the pollutant removal in eutrophication water
Originally it is controlled, Water quality can be kept for a long time, there is good economic benefits, ecological benefits and social benefit；
(2) inorganic agent of the invention is used, reduces 30% or more project investment compared with than similar techniques, and substantially reduce bed mud to big
The secondary pollution risk of gas, soil, underground water, and repair time is short, after reparation water quality maintenance cost reduce 40-65% with
On, compared with than similar techniques, strain injected volume reduces nearly 30%, the reliable nothing of microbial safety used by the method for the present invention inorganic agent
Poison, in purifying water body, running cost is low, only need to periodically add bacterium powder, easy to operate, maintenance is simply, energy consumption is low, easy to spread makes
With；
(3) modified oyster is significant to low phosphorus solution adsorption effect, and vermiculite, wood powder charcoal, bamboo powder charcoal are to ammonia nitrogen
Adsorption effect is preferable, after mixing more preferably to ammonia nitrogen, total phosphorus clean-up effect in actual sewage.
