Abstract
The invention discloses a method for removing germanium in sewage and belongs to the field of sewage treatment in environmental protection. The method comprises the following steps of: placing aluminum trioxide into a triangular round-bottom flask; adding aluminum potassium sulfate dodecahydrate, magnesium sulfate and water into the flask; heating and continuously agitating; when the temperature is raised, adding calcium aluminate powder; adding ferric trichloride and octadecy trimethyl ammonium bromide into reactants and agitating and mixing uniformly; adding the substances into wastewater containing the germanium; and agitating, standing, precipitating and discharging effluent into a clean water pool. The method disclosed by the invention is simple in process flow, simple in operation, lower operation cost, no sludge, high germanium removing effect and the like; and no sediment is generated and secondary pollution is not caused, and metal oxides in the effluent and the wastewater can be recycled.
Description
Technical field
The present invention relates to a kind of method of removing germanium in the sewage, particularly process the waste water of germanium concentration in 10～100mg/L scope, belong to field of waste water treatment in the environment protection.
Background technology
The discharging that contains heavy metal germanium waste water has serious harm to HUMAN HEALTH and industrial or agricultural activity, have the harm such as persistence, toxicity be large, seriously polluted, in case can not be biodegradable behind the entered environment, great majority participate in the food chain circulation, and finally in vivo accumulation, destroy organism normal physiological Metabolic activity, be detrimental to health.Along with the day by day increase of the mankind to activities in production such as the exploitation of heavy metal, smelting, processing, the heavy metal germanium waste water of generation is all greatly to increase in quantity or on the kind, has caused serious environmental pollution and the wasting of resources.Therefore the improvement that contains heavy metal germanium waste water is still a problems to be solved in world's field of Environment Protection.Notification number is that CN86106414 discloses the method that a kind of electrolytic process is processed germanic waste water, and the water quality after the method is processed is good, recyclable germanium, and occupation area of equipment is large, and technical process is complicated, one-time investment is high.
Summary of the invention
The objective of the invention is provides a kind of method of removing germanium in the sewage for overcoming the deficiencies in the prior art, and this invented technology flow process is simple, running cost is low, and obvious processing effect produces without precipitation, can not cause secondary pollution, and the equal recoverable of the metal oxide in water outlet and the waste water.
Concrete treatment step of the present invention is:
(1) getting the alchlor mass content is that waste hydrochloric acid 100～120mL of 10～17% places 500mL triangle round-bottomed flask, and described waste hydrochloric acid acidity is that 10.5%, pH is 1.0～1.5;
(2) add 5～10g Potassium aluminum sulfate dodecahydrate, 6～8g sal epsom, 50～68g water to flask;
(3) heat, and constantly stir, when temperature rises to 68 ℃, add 50～60g calcium aluminate powder;
(4) continue to heat up, reaction is 4～5 hours when temperature rises to 110 ℃～115 ℃;
(5) in above-mentioned reactant, adding 5～10g iron trichloride and 6～9g Cetyltrimethylammonium bromide, mix;
(6) get above-mentioned substance and join in the germanic waste water, the amount of adding is 100～150mg/L, and rapid stirring 10 minutes slowly stirred 30～45 minutes again, leave standstill, and precipitation, water outlet is drained in the clean water basin.
Application method of the present invention is: get alchlor and place the triangle round-bottomed flask; Add Potassium aluminum sulfate dodecahydrate, sal epsom, water to flask; Heat, and constantly stir, when temperature rises, add calcium aluminate powder; Mix at adding iron trichloride and Cetyltrimethylammonium bromide in above-mentioned reactant; Get above-mentioned substance join in the germanic waste water stir, leave standstill, precipitation, water outlet enter in the clean water basin and get final product.
The invention has the beneficial effects as follows: it is simple that the present invention has technical process, simple to operate, and working cost is lower, high except the germanium effect without sludge creation, produces without precipitation, can not cause secondary pollution, and the equal recoverable of the metal oxide in water outlet and the waste water.
