Description
Technical field
The present invention relates to technical field of sewage, it is specifically related to a kind of environment protection sewage inorganic agent and preparation method thereof.
Background technique
Sewage includes that sanitary sewage, trade effluent and first rain diameter flow into other useless water such as drainpipe, refers generally to pass through
The water that certain standard is not achieved in pure processing difficulty is made after being unable to recycling or level-one pollution after certain technical treatment.
With the fast development of China's chemical industry, various novel products are applied to all trades and professions, especially medicine, change
The trade effluent generated in the industry of the heavily contaminateds such as work, printing and dyeing can pollute rivers and lakes surface water, lead to water plant death even
Disappearance, can also penetrate into underground water, polluted underground water, penetrate into soil, cause soil pollution, influence plant and edaphon
Growth, causes serious environmental pollution.
In national annual sewage discharge, only 10% sanitary sewage and 60% trade effluent are handled, and wherein about
There is the water outlet of half Industrial Waste Water Treatments facility that national emission standard is not achieved, remaining untreated sewage is then directly discharged into rivers
In lake, the water environment in China is caused to be subject to serious pollution and destroy.According to statistics, national seven big water systems and inland river
In 110 key sections, belong to 4 classes and 5 class water bodys accounts for 39%；Urban ground water pollution is generally serious, and in further deterioration
Trend, 136 flow through in the river in city, belong to 4 classes, 5 classes and more than 5 class standards up to 76.8%；About 50% city
Underground water is by different degrees of pollution；The biggish fresh water lake in the whole nation such as eutrophic extents such as Dian Chi, Taihu Lake and Chaohu are year by year
Aggravation；The drinking water source in some areas is heavily contaminated, causes to seriously endanger to people's health.
Sewage-treating agent in the prior art is all liquid, it will usually introduce new pollution, and the inorganic agent of solid
It direct plunges into water, filtering, but solid processing agent in the prior art can make sewage under the irradiation of long-time sunlight
Processing capacity is greatly reduced.Therefore, sewage can be effectively treated by needing one kind, and treatment effect is lasting, not generate the ring newly polluted
Protect sewage-treating agent.
Summary of the invention
In view of this, the present invention provides a kind of environment protection sewage inorganic agents.
To achieve the goals above, the present invention adopts the following technical scheme:
Environment protection sewage inorganic agent, is composed of the following raw materials by weight: 30-55 parts of polyacrylamide, Sodium Polyacrylate 20-45
Part, 5-15 parts of PERFORMANCE OF MODIFIED VERMICULITE, 2-8 parts of medical stone, 1-5 parts of methylisothiazolinone, 2-10 parts of aluminum aluminum sulfate, polypropyleneimine 5-
10 parts, 10-20 parts of sodium metasilicate, 5-15 parts of chitosan, 1-5 parts of regulator, 4-12 parts of surfactant.
Further, above-mentioned chitosan is carboxymethyl chitosan and/or hydroxyethyl chitosan.
It is using above-mentioned further beneficial effect: the amino easily shape in the chitosan molecule monomer that the present invention uses
At amine cation, there is good integration to metal, the heavy metal ion in waste water can be effectively removed.
Further, above-mentioned regulator is sodium carbonate and/or sodium bicarbonate.
Further, above-mentioned surfactant is dodecyl sodium sulfate, stearic acid, glycine betaine, polyoxyethylene alkyl amine, ten
One or more of dialkyl amido propionic acid.
Be using above-mentioned further beneficial effect: the surfactant that the present invention uses can effectively increase the present invention
The treatment effect of inorganic agent, service life and reaction settling velocity.
The beneficial technical effect of the present invention lies in: the present invention will not generate noxious material using environmental protection material, environmental-friendly,
It is at low cost；Raw material sources are extensive, can effectively remove the pollutant in water, and processing sewage is thorough, and cost of water treatment is low, and the present invention produces
Product are using will not influence the pH value of aqueous solution, and when use is not influenced by the pH value of sewage to be treated, and no matter sewage is acid
Property, or alkalinity, it does not need to be adjusted its pH value.Inorganic agent of the present invention is to the heavy metal and mushroom in sewage
Pollutant all has preferable processing adsorption function, nontoxic；Practical value with higher and good application prospect.
The present invention also provides the preparation methods of above-mentioned environment protection sewage inorganic agent, comprising the following steps:
(1) each raw material is weighed in parts by weight；
(2) medical stone and PERFORMANCE OF MODIFIED VERMICULITE powder are put into pulverizer and smash it through 200-500 mesh molecular sieve, will mixed
Powder carries out calcining 10-30min at 450-550 DEG C, is then placed in the powder for being ground into 200-325 mesh in pulverizer again；
(3) by polyacrylamide, Sodium Polyacrylate, methylisothiazolinone, aluminum aluminum sulfate, polypropyleneimine, sodium metasilicate,
Chitosan, regulator, surfactant are put into ball mill after ball milling 3-6h 200-325 mesh molecular sieve excessively and obtain mixture；
(4) mixture of powder and step (3) that step (2) obtains mix and stir at 150-300r/min
20-30min handles 20-50min at 80-100 DEG C to get the environment protection sewage inorganic agent.
Further, the PERFORMANCE OF MODIFIED VERMICULITE is obtained using following preparation method:
(1) it pre-processes: vermiculite being placed under the conditions of temperature is 110-120 DEG C after dry 5-10h is in temperature by vermiculite
1-2h is calcined under 450-550 DEG C of high temperature；
