A kind of method processing manganese ore waste water
Technical field
The present invention relates to technical field of waste water processing is and in particular to a kind of method of process manganese ore waste water.
Background technology
The exploitation of manganese ore can produce substantial amounts of manganese ore waste water, and manganese ore waste water can reduce drain pipe in long-term discharge process
Water passing capacity, substantial amounts of precipitation can be produced in pipeline, when serious, also can cause pipeline breaking, and if entered containing the waste water of manganese
Enter in our normal Drinking Waters, chronic poisoning also can be caused to be detrimental to health, but China's manganese resource is relatively scarce
Weary, rich ore is less, due to the restriction of each side such as equipment and treatment technology in the exploitation of a large amount of manganese ores and deep-processing process, makes
The waste material containing manganese of China and Mn-bearing waste water pollution are more serious, and manganese ore mine water pollution can be divided into mineral pollution, Organic substance dirty
Dye and germ contamination.Also there is radioactive material contamination and thermal pollution in some mines.Mineral pollution has sand, mud granule, ore deposit
Thing impurity, dust, solvency, bronsted lowry acids and bases bronsted lowry etc.;Organic Pollution has the oxygen of oils and fatss, biological metabolic product, timber and other materials
Change catabolite.The polluting of rock dust, breeze and the associated mineral that germ contamination is mainly exploited, be scattered in transportation.Manganese
One big feature of Ore mine water is that manganese ion content is high, and the manganese in mine water is by the oxide of manganese, sulfur in rock and mineral
Caused by compound, carbonate and silicate etc. are dissolved in water.In oxidizing process, manganese migrates generation mn2 in water, therefore in mine water
Manganese is mainly existed with mn2 form.During mining, discharge a large amount of waste water barren rocks from down-hole, pollute river, occupy
A large amount of farmland, mountain forest, grasslands, if destroy ecological balance it can be seen that manganese ore waste water deal with improperly will result in serious
Environmental pollution, passes through substantial amounts of experiment for this present inventor and studies, there is provided a kind of method processing manganese ore waste water.
Content of the invention
For solving above-mentioned technical problem, the invention provides a kind of method processing manganese ore waste water.
The present invention is achieved by the following technical programs:
A kind of method processing manganese ore waste water, the method comprises the following steps:
A, absorption: manganese ore waste water is imported in sedimentation tank, adds char-forming material, stewing process 3-7h in manganese ore waste water;
B, irradiation: after the completion of stewing process, the supernatant taking out waste water carries out ultraviolet treatment with irradiation, then add strong
Oxidant, according to the linear velocity stirring 16-20min of regulation;
C, second adsorption: continuously add char-forming material in the supernatant completing to treatment with irradiation, process 1-2h;
D, coagulation discharge: add flocculant in the supernatant completing to second adsorption, stand after stirring reaction 16-20min
1h separates and discharges.
Char-forming material in described step a is made up of following raw material: rice husk 8-14 part, timber 8-14 part, swelling
Native 6-12 part, kieselguhr 4-12 part, calcite 4-8 part, quartz sand 4-8 part, zeolite 2-8 part, gelatin 4-10 part.
The preparation method of described char-forming material is: by calcite and zeolite be crushed to after 220-260 mesh with bentonite, diatom
Soil, quartz sand, mix homogeneously obtain compound, after the wood particle that timber is cut into a diameter of 0.8-1cm is mixed with rice husk
Pour the diesel oil improved quality as wood particle and rice husk 5-7%, after igniting is fired into black wood charcoal, is put out by water with water and obtain carbon material, according to than
After compound is mixed homogeneously with carbon material by example, put into and in pulverizer, be crushed to 220-260 mesh, obtain mixed powder, by mixed powder
After material is mixed with water according to mass ratio, add gelatin, obtain the carbonization material for wastewater treatment finally by dried
Material finished product.
The ratio mixing for 1:1 according to mass ratio of the mixed proportion of described compound and carbon material.
Described step mixed powder is 1:1 with the mass ratio of water.
The time of described step b middle-ultraviolet lamp treatment with irradiation is 8-16min, and irradiation distance is 12-18cm.
The temperature of described dried is 60-70 DEG C, and drying time is 20-30min.
Strong oxidizer in described step b is potassium permanganate.
Stirring wire velocity control in described step b is 8-12m/s.
Flocculant in described step d is iron sulfate.
The beneficial effects of the present invention is: present invention employs absorption method twice, effectively will be a large amount of in manganese ore waste water
Harmful substance suctions out, and the process of combined with ultraviolet radiation, further waste water is sterilized, the self-control carbon that the present invention adopts
Change material and there is extremely strong absorption, clean-up effect, and processing method simply, effect substantially, finally coordinates efficient flocculant again,
Serve with char-forming material and mutually make up, propose efficient effect.
