Principle of wastewater treatment

1 to 3, the toxic waste lime treatment method of the present invention will be described as follows.

The present invention is a carbonate pure water manufacturer having the ability to steam purify waste lime, which is heavily impregnated with cadmium, mercury, potassium chloride, gypsum, polychlorinated biphenyl (PCB), dioxin, and the like. The present invention relates to a method for treating toxic waste lime, which can completely clean the poison poison deeply impregnated with the waste lime by using a ready-mixed blasting vacuum extractor using strong carbonated water (carbonate distilled water).

Toxic waste lime treatment method of the present invention is the process of inserting the toxic waste lime into the waste lime inlet 14 of the ready-mixed blast-type vacuum extractor 10,

Through the above process, the waste lime of harmful substances inserted into the blast-type vacuum extractor 10 is press-fitted using the vacuum pump 13 and the condenser 12, and the boiler 11 in which the burner 6 is installed is heated and decompressed. Vacuum purifying harmful substances of waste lime to push the waste water out;

The process of transferring the wastewater and the leachate (9) to the shower tunnel (17) through the above process to precisely filter the toxic from the leachate (9) or the blast-type vacuum extractor (10) with a vacuum filter (15),

After the above process, wastewater is vacuum filtered in the shower tunnel (17) and put into a high pressure boiler (1) having a steam purification capability. The process automatically enters the water level into the evaporation pipe (2) and the low pressure evaporation pipe (3). ,

When the incinerator (5) and the burner (6) is ignited through the above process, when the high pressure boiler (1) is heated, high pressure steam is generated, and the high pressure steam is heated at 1200 ° C. or higher in the high pressure boiler (1) to evaporate together. (COD), biological oxygen demand (BOD), etc. are burn-purified under dry steam at 600 ° C with air injected into the steam by the steam purifier (4), and polychlorinated biphenyls (PCB) and dioxins are slag at 1200 ° C or higher. Process,

The distilled water purified through the above process is mixed with a trace amount of carbonic acid and heat exchanged and used as evaporation heat to evaporate the water of the medium pressure evaporation tube (2), and the water of the low pressure evaporation tube (3) is purified and liquefied in a reduced pressure liquefier All the distilled water is produced by the strong washing power carbonic acid distilled water is made of a process to be transferred to the reservoir (8).

The washing waste water is first transferred to the shower tunnel 17 to neutralize the carbon dioxide (CO2) and calcium (Ca) in the strong alkali from the incinerator.

If the high-pressure boiler (1) is injected by filtration of the fine waste water, the concentration of calcium chloride (CaCL) in the medium-pressure evaporation tube (2) low-pressure evaporation tube (3) is separated by vacuum concentration drying with a vacuum concentration dryer (16).

It is further provided with a process of separating the beneficiation specific gravity separated by sand and the like, the waste lime washed through the last process.

The distilled water thus purified is mixed with a trace amount of carbonic acid and heat exchanged to be used as evaporation heat to evaporate the water in the medium pressure evaporation tube (2). The water vapor evaporated in the pressure-evaporating tube (2) is purified in the same way as the water in the low-pressure evaporation tube (3) is liquefied in a reduced pressure liquefier.

All the distilled water liquefied as described above is produced as carbonic acid distilled water with strong washing power and is transferred to the storage tank 8 and stored. Calcium chloride in the concentrated concentrated water is transferred little by little from the low pressure evaporation tube (3) to the vacuum concentration dryer (16) to change into toxic calcium chloride. Toxic calcium chloride is retreated to non-toxic calcium chloride in ultra-high melting furnaces.

The blast-type vacuum extractor 10 is connected to the boiler 11 which warms the waste lime in the washing machine in a short time with a ready-mixed concrete type. Chemical oxygen demand (COD), biological oxygen demand (BOD), mercury, cadmium, polychlorinated biphenyl (PCB), dioxin, etc., impregnated deeply in waste lime, are exploded by decompression vacuum at a pressure of 1.5Kg / ㎠ temperature at 120 ℃. Toxic toxic components deeply impregnated are expelled. The discharged wastewater is continuously transferred to the shower tunnel 17. In the heating boiler, carbonic acid particle steam having a strong cleaning power of 400 ° C. liquefies the waste lime continuously while rapidly heating it. Lime, washed for about 1 hour and 30 minutes and completely toxin-extracted, is separated from sand with light in the beneficiator and is then converted into non-toxic lime.

Incinerator (5), shower tunnel (170), vacuum filter (15), vacuum condenser (16), the role of leachate waste water and washed waste water carbon dioxide (CO2) and strong calcium from the shower tunnel (17) and incinerator Alkali combines to form a marble-like constituent: The original shower tunnel 17 was used to purify combustion gases, but neutralizes the waste lime, and the shower tunnel 17 is equipped with an automatic continuous vacuum filter 15. The filtered sediment and wastewater from the concentrated shower tunnel 17 are sent to the vacuum condenser 14 every hour for complete drying .. Completely dried toxic (mercury, cadmium, PCB, dioxin) and sediment, in concentrated concentrated water Toxic components are melted in ultra-high melting furnaces (1600 ℃) and fall into the water, turning into sand in water.
