Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to a treatment system and process for treating high-concentration toxic wastewater using an ultraviolet-Fenton method. Background Art

[0002] The development of many industries has caused a lot of problems in the treatment of industrial wastewater, which is also a dilemma faced by many manufacturing companies, especially some industries that will bring high-concentration industrial wastewater. These high-concentration industrial wastewaters have the following characteristics:

[0003] ① High concentration of organic matter. This type of wastewater contains a large amount of organic matter, such as various organic acids, alcohols, ketones, aldehydes, esters, ethers, etc. These substances often come from the chemical, pharmaceutical, food processing and other industries; ② Many difficult-to-degrade substances. High-concentration industrial wastewater often contains some difficult-to-degrade organic matter, such as polycyclic aromatic hydrocarbons, phenols, polychlorinated biphenyls, etc. These substances are very harmful to the environment; ③ Extreme acidity and alkalinity. Some industrial wastewater may show extreme acidity and alkalinity, such as acidic wastewater from sulfuric acid plants and nitric acid plants, and alkaline wastewater from alkali plants and paper mills; ④ Biological toxicity. High-concentration industrial wastewater usually contains substances that are harmful to organisms, such as certain organic solvents, heavy metals, etc. These substances pose a great threat to aquatic organisms and the ecological environment. Other physical properties include dark color and strong odor: Due to the presence of various chemical substances, these wastewaters usually have special colors and odors, and sometimes may contain suspended matter, resulting in turbid water. High-concentration industrial wastewater like this is difficult to treat directly using conventional, simple biochemical methods. If physical, chemical and other methods are used, the treatment cost will be very high. The dilution and biochemical treatment methods require a large amount of water resources, which is not environmentally friendly. In addition, the treatment tank is larger and the construction cost increases.

[0004] At present, the oxidation methods used for high-concentration industrial wastewater mainly include Fenton reagent oxidation, supercritical water oxidation, catalytic wet oxidation and electrochemical oxidation.

[0005] The essence of the Fenton process is the chain reaction between divalent iron ions (Fe2+) and hydrogen peroxide to catalyze the generation of hydroxyl radicals, which have strong oxidizing ability and an oxidation potential second only to fluorine, up to 2.80 V. In addition, hydroxyl radicals have high electronegativity or electrophilicity, and their electron affinity is as high as 569.3kJ. They have strong addition reaction characteristics, so Fenton reagent can non-selectively oxidize most organic matter in water, and is particularly suitable for the oxidation treatment of organic wastewater that is difficult to biodegrade or difficult to be oxidized by general chemical oxidation.

[0006] Fenton method has strong oxidation ability: Fenton reagent uses H2O2 to produce hydroxyl radicals (·OH), and its oxidation potential is as high as 2.8V. It has strong oxidation ability and can non-selectively oxidize most organic matter in water. Mild reaction conditions: Fenton reaction can be carried out at room temperature and pressure, and the reaction conditions are mild. Wide range of applications: Fenton reagent is not only suitable for various wastewater treatments, but also can be used for the treatment of gaseous pollutants. Removal of difficult-to-degrade organic matter: Fenton reagent can effectively remove difficult-to-degrade organic matter that cannot be removed by traditional wastewater treatment technology. Environmentally friendly: Fenton reagent does not produce harmful substances during the reaction process, and the reaction product is water, which is environmentally friendly. However, Fenton technology also has some disadvantages, such as low utilization rate of H2O2, inability to fully mineralize organic matter, and the need to consume catalysts.

[0007] For example, the application number 202020522399.0 discloses a UV-Fenton wastewater treatment experimental device, including a control base, an inner beaker and an anti-ultraviolet outer cover, wherein the inner beaker is placed on the top of the control base, a pH meter for measuring the pH value of wastewater is arranged in the inner beaker, the anti-ultraviolet outer cover is detachably arranged outside the inner beaker and supported by the control base, an ultraviolet lamp is arranged on the inner wall of the anti-ultraviolet outer cover, a dosing port is provided on the top of the anti-ultraviolet outer cover, an anti-ultraviolet cover is detachably installed at the dosing port, and an ultraviolet lamp control switch for controlling the opening and closing of the ultraviolet lamp and a pH display screen for displaying the measured value of the pH meter are arranged on the control base. The utility model utilizes an artificial ultraviolet light source to irradiate wastewater, thereby enhancing the oxidizing ability of the oxidant, so as to quickly and effectively remove organic matter in the wastewater during the wastewater treatment process.

[0008] However, the current Fenton method for treating wastewater often has problems such as being unable to eliminate dead corners in stirring, obtaining large-area water exchange, and uneven stirring, which leads to long reaction time, incomplete reaction, large amounts of reagents used, high wastewater treatment costs, complex equipment structure, high investment costs, low equipment automation, and high labor intensity. Summary of the invention

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. By setting a cone-tower jet agitator in the acidification reaction mechanism, during the acidification pretreatment before treating high-concentration toxic wastewater, the agitator moves tangentially along its radial direction. Under the action of its tank wall, a circulating water flow from bottom to top is formed, effectively eliminating the stirring dead corner and obtaining a large area of ​​water exchange. In addition, air is sprayed in through the center hole and ejected from the cone-tower jet agitator, forming a large number of bubbles in the wastewater to stir and impact the liquid, thereby improving the oxygen supply and accelerating the solution acidification speed and acidification uniformity.

[0032] 2. By setting up a recoil stirring tank in the acidification reaction mechanism, the spiral blade adopts a turbine umbrella structure. When the agitator rotates, negative pressure is formed, which increases the central jet speed, and the solution added with the liquid medicine in the upper layer is sucked into the recoil stirring tank, and flows out through the guide groove and the guide port. The recoil stirring tank rotates in the opposite direction to the spiral blade agitator, forming vortices and swirls at the guide port, thereby improving the circulation of the solution, improving the stirring efficiency, and increasing the oxidation rate of high-concentration toxic wastewater. At the same time, the sufficiency of the reaction is improved, the dosage of the agent is reduced, and the production cost is reduced.

[0033] 3. By setting the supporting right-angle seat, vertical supporting wheel and horizontal supporting wheel, the smooth movement of the gear plate can be ensured, the equipment structure can be simplified under the same function, and the manufacturing cost of the equipment can be reduced.

[0034] 4. By setting up strip-type ultraviolet lamps, which are set at high positions such as the diversion port, ultraviolet irradiation is carried out at the vortex position, which improves the oxidation efficiency and reduces the time for wastewater degradation.

[0035] 5. By setting a flexible spiral agitator in the neutralization tank cover, during the acid-base neutralization and flocculation process of the reacted liquid, the effectiveness of stirring is guaranteed and the impact of stirring on the solution is reduced, thereby increasing the neutralization speed and the flocculation speed.

[0036] 6. By setting fan-shaped stirring blades and perforated support plates, the method of handling floccules is simplified. The cylinder is used to separate the liquid and floccules, and high-pressure gas is used to impact the floccules to the outlet, which improves the overall working efficiency of the equipment and the degree of automation of the equipment.

[0037] 7. By setting up a portable automatic drug-feeding mechanism, the manual action of adding drugs to the drug-feeding box is reduced, the labor intensity is reduced, and the overall automation level of the equipment is improved. BRIEF DESCRIPTION OF THE DRAWINGS
