Description

Technical Field

[0001] The invention belongs to the field of water treatment, and in particular relates to a 3O high-energy composite oxygen preparation device and a process thereof applied to coking wastewater. Background Art

[0002] With the acceleration of industrialization and urbanization, the current water shortage and water pollution problems in my country are becoming more and more serious. The main sources of pollution are industrial wastewater, domestic sewage, agricultural wastewater, etc., among which industrial wastewater is the most serious. In recent years, the construction of industrial wastewater treatment facilities has been accelerating. The traditional treatment process is to first precipitate the sewage and add chlorine for oxidation disinfection. However, the wastewater treated by the traditional treatment process still contains some suspended particles, as well as many refractory organic pollutants, bacteria and heavy metals that are toxic and harmful to the human body, and does not meet the reuse water standard. In addition, the use of chlorine oxidation disinfection is prone to generate by-products in the water, such as chloroform, halogenated acetic acid, etc., causing secondary pollution; due to the presence of soluble organic matter, it is not conducive to destroying the stability of the colloid and the conventional treatment process is significantly reduced in the removal effect of the turbidity of the raw water. Therefore, the present invention provides a 3O high-energy composite oxygen preparation device and a process thereof for coking wastewater, which is urgent to reduce its harm to human health. Summary of the invention

[0005] Furthermore, the pure oxygen preparation machine is provided with an air inlet pipe, the air inlet pipe is provided with an oxygen filter, the air inlet pipe is also provided with a water valve, and the oxygen filter is located at the inlet end of the water valve; a first supporting box is provided outside the pure oxygen preparation machine, a first supporting plate is provided below the pure oxygen preparation machine, and the first supporting plate is connected to the first supporting box; four walking devices are provided below the outer shell, a touch screen is provided on the side of the outer shell, an electric control box is provided on one side of the outer shell, a chiller is provided on one side of the electric control box, a cold water outlet and a cold water inlet are provided on the chiller, and the cold water inlet and the cold water outlet both pass through the electric control box and the outer shell; handles are provided on both sides of the outer shell for easy movement.

[0006] Further, the ozone generator includes a stainless steel container, a pair of vacuum ultraviolet lamps are arranged inside the stainless steel container, and the pair of vacuum ultraviolet lamps are symmetrically arranged on the inner wall of the stainless steel container; a cooling water jacket is arranged outside the stainless steel container, a second support plate is arranged below the cooling water jacket, and the second support plate is connected to the shell; an air inlet pipe is arranged at one end of the ozone generator, an electromagnetic flowmeter is arranged on the air inlet pipe, a first water outlet pipe is arranged at the other end of the ozone generator, a water pump is arranged on the water outlet pipe, and a second water outlet pipe is arranged at the other end of the water pump, a 3O high-energy oxygen generator is arranged below the second water outlet pipe, a high-energy oxygen contactor is arranged below the 3O high-energy oxygen generator, and a third water outlet pipe is arranged on one side of the high-energy oxygen contactor; a sewage pipe is arranged on the ozone generator, and the sewage pipe passes through the shell and is connected to the outside; a cold water outlet and a cold water inlet are connected to the cooling water jacket to realize a cooling water cooling cycle.

[0007] Furthermore, the rate of generating nano-microbubbles by the 3O high-energy oxygen generator is 20kg / h, and the power of the 3O high-energy oxygen generator is 5+7.5KW.

[0008] Furthermore, the air intake of the 3O high-energy composite oxygen production device applied to coking wastewater is 6Nm 3 / h; intake air concentration is greater than 850g / m 3 ; The voltage of the 3O high-energy composite oxygen preparation device applied to coking wastewater is 220V~50Hz; The rated power of the 3O high-energy composite oxygen preparation device applied to coking wastewater is 0.8KW.

[0009] Furthermore, the main body material of the 3O high-energy composite oxygen preparation device applied to coking wastewater is 316 stainless steel.

[0010] The present invention also provides a 3O high-energy composite oxygen preparation process, which includes the following contents: a pure oxygen preparation machine prepares oxygen, and then the oxygen is introduced into an ozone generator to dissolve in sewage to form ozone, and the ultraviolet light generated by a vacuum ultraviolet lamp converts the ozone in the water into active oxygen atoms and hydroxyl free radicals.

[0011] Furthermore, the pure oxygen preparation machine has a pure oxygen preparation rate of 50m / h, a compressed air rate of 12m / min, and a power of 15KW.

[0012] Compared with the prior art, the 3O high-energy composite oxygen preparation process of the present invention contains 3 oxygen atoms through the preparation of ozone, and the oxidation potential reaches 8. The solubility in water is 9.2mlO3 / L, which is higher than that of oxygen. When the dissolved concentration in water is higher than 20mg / L, it has strong oxidizing property, the redox potential is 8V, and the oxidizing ability is only lower than F2 in the single substance. The residual macromolecular, long-chain, and difficult-to-biodegrade organic matter in the wastewater can be directly mineralized into carbon dioxide and water, and partially decomposed into small molecular biodegradable substances, destroying the structure of non-biodegradable organic matter, reducing toxicity, and improving the B / C ratio, thereby ensuring the treatment effect of the subsequent biochemical method.

The equipment is used in advanced strong oxidation of sewage treatment, deodorization of biochemical pools, and deodorization of chemical waste gas and other oxidation reactions; under the action of ultraviolet rays, atomic oxygen further generates hydrogen peroxide, which is further decomposed into hydroxyl radicals, and the soluble pollutants and molecular particles in the wastewater are open-chain oxidized into H2O and CO2 and form colloidal cloud particles, and hydroxyl radicals can oxidize almost all organic matter; it is purified and removed through coagulation reaction precipitation, thereby achieving the purpose of reducing pollution indicators. The advantage of this process is that it does not produce or produces very little sludge, which is different from the Fenton method that produces sludge due to chemical reactions;

[0014] Air is introduced into the air inlet pipe of the present invention, and an oxygen filter protects the water valve to reduce impurities at the inlet end of the water valve. Air enters the pure oxygen preparation machine to produce oxygen, oxygen enters the ozone generator, sewage enters the ozone generator from the sewage pipe, oxygen dissolves in the sewage to produce ozone, and the ozone is irradiated with high energy by a vacuum ultraviolet lamp with a wavelength of 172nm to produce active oxygen atoms and hydroxyl free radicals with higher concentration and stronger oxidation ability, and soluble pollutants in the wastewater are oxidized.
