Description
Technical field
The present invention relates to a kind of method for processing containing water-soluble salt and organic hazardous waste, belonging to the desalting processing technical field of hazardous waste.
Background technology
Perfect along with National Environment Policy Act Laws & Regulations, the management of hazardous waste and disposal receive extensive attention.But the innoxious and comprehensive utilization of hazardous waste still faces many difficulties, the physical behavior of such as numerous industrial residu is complicated, except the danger of regulation is given up except classification and code, the composition of major part hazardous waste is very complicated, the many index of hazardous waste judging standard may be related to, causing the product after the treated disposal of hazardous waste is still hazardous waste, finally can only landfill disposal.Wherein special circumstances is hazardous waste containing water-soluble inorganic salt, although most inorganic salts are not classified as Hazardous Waste List, due to its mixture feature, actual final landfill disposal can run into special salt problems of dissolution.Such as landfill yard General Requirements process Leachate site, the Leachate site caused by rainwater infiltration by long-term washing water soluble, as sodium chloride.Result by be mixed with soluble-salt the stabilized process landfill of hazardous waste after, long-term rainwater drip washing will cause the dissolving of soluble inorganic salt, finally need by being disposed to surface water system after the process of leachate treatment system, form the deterioration of the indexs such as the total dissolved solid of surface water body, and the salination problem of possibility weighting lined aquaporin.
Chinese patent literature CN102424435A disclosed " the quick desalination method of dangerous waste incinerator flue gas washing tower high-concentration salt-containing wastewater and device for cleansing and recycling ", attempt the disposal of the high-salt wastewater solving danger waste burning process, but dissolubility inorganic salts will still need further process.Hazardous waste---dissolubility sodium, sylvite in flying dust that CN102161490A disclosed " a kind of system and method extracting k-na salt from incineration of refuse flyash " produces for consumer waste incineration, proposing corresponding separation method, is a kind of Beneficial solving relevant issues.The method is but difficult to direct utilization to the disposal of other saliferous hazardous wastes.
Summary of the invention
The present invention is directed in mixed salt organic matter class hazardous waste, the deficiency that water soluble salt treatment technology exists, propose a kind of simple and easy to do, containing water-soluble salt that treatment effect is good and organic hazardous waste recycling processing method.
Containing water-soluble salt of the present invention and organic hazardous waste recycling processing method, comprise the following steps:
(1) when saliferous, water and organic mixing hazardous waste are liquid condition, first make moisture wherein and other volatile substances heating evaporation, to reduce the load of subsequent treatment, then high-temperature hot desorption is carried out, when mix hazardous waste be thick semisolid or solid-state time, directly carry out high-temperature hot desorption, desorption temperature is 320-500 DEG C, the low boiling moisture that desorption obtains and organic matter, after stratification, carry out water treatment and burning disposal respectively;
(2) to the waste residue that elevated temperature desorption produces, utilize fresh water (running water) to dissolve and leaching, dissolving water temperature is 60-100 DEG C, obtains mother liquor and water-insoluble salt and debris after filtration, carries out burning disposal to water-insoluble salt and debris;
(3) the mother liquor charcoal absorption that leaching obtains purifies, carry out burning disposal to isolated active carbon, carry out crystallization treatment to the saliferous mother liquor after being refined by adsorption cleaning, the water temperature of crystallization process is 60-100 DEG C, obtain crystalloid mixed inorganic, mother liquid recycling;
(4) the crystalloid mixed inorganic obtained is after washing, and detect its quality, certified products are sold as outside salt-mixture;
(5) underproof mixed inorganic then needs again to dissolve and be recrystallized after testing, and repeats step (4); The circulating mother liquor of recrystallization directly returns to mix with first time crystalline mother solution and utilizes;
(6) condensed water that recrystallization produces can mix with fresh water, is directly used in dissolving and the leaching of step (2).
The present invention is simple and easy to do, and treatment effect is good, can carry out effective desalination, and do harmless treatment to salt solution organic matter mixing hazardous waste, is also conducive to the final disposal of such hazardous waste simultaneously.
Accompanying drawing explanation
Fig. 1 is the schematic flow sheet of containing water-soluble salt of the present invention and organic hazardous waste recycling processing method.
Detailed description of the invention
Fig. 1 gives the flow process of containing water-soluble salt of the present invention and organic hazardous waste recycling processing method, specifically comprises the following steps:
(1) according to the physical property determination preprocess method of saliferous, water and organic matter mixing hazardous waste.When saliferous, water and organic mixing hazardous waste are liquid condition, first processed, makes the volatile substances heating evaporations such as moisture wherein, reduces the load of subsequent treatment, then enters high-temperature hot desorption operation.When mix hazardous waste be thick, semisolid or solid-state time, directly can enter high-temperature hot desorption operation.High-temperature hot desorption equipment can adopt rotary kiln, pyrolysis reactor etc., desorption temperature 320-500 DEG C.The low boiling moisture that desorption obtains and organic matter, after stratification, carry out conventional water treatment and burning disposal.
(2) waste residue that elevated temperature desorption produces contains the residue of inorganic salts and organic cracking generation, and fresh water can be utilized to dissolve, and water temperature at 60-100 DEG C, should leach this residue, the water-insoluble salt obtained after filtration and debris, carries out burning disposal in the lump.
(3) mother liquor that leaching obtains may containing a small amount of organic matter, after powdered activated carbon adsorption cleaning, isolated active carbon is burned, saliferous mother liquor after refining is through the crystallization of vaporation-type industry crystallizer, the water temperature of crystallization process should at 60-100 DEG C, obtain crystalloid mixed inorganic, mother liquid recycling (carrying out crystallization again).For controlling impurity concentration in mother liquor, a small amount of circulating mother liquor removal system, by the hardness in haline water treatment system removal mother liquor and heavy metal.
(4) mixed inorganic of crystallization acquisition is after washing, and detect its quality, the certified products conformed to quality requirements are sold as outside salt-mixture, and as the raw material of other enterprise, further refining spearation obtains multiple pure product.
(5) underproof mixed inorganic after testing, then need again to dissolve and be recrystallized, and repeat step (4).The circulating mother liquor of recrystallization, after repeatedly circulation, directly can return to mix with first time crystalline mother solution and utilizes (carrying out crystallization).
(6) condensed water that recrystallization produces can mix with fresh water, is directly used in dissolving and the leaching of step (2).
