Description

Technical Field

[0001] The invention relates to the technical field of waste liquid treatment, in particular to an industrial organic waste liquid recovery and treatment method and a device thereof. Background Art

[0002] Liquid waste containing a large amount of organic pollutants is generated in the industrial production process. These waste liquids usually come from multiple industries, including but not limited to chemical, pharmaceutical, food processing, printing and dyeing, papermaking, petroleum refining, etc. Due to their complex composition, high toxicity, high concentration and poor biodegradability, these waste liquids, if discharged directly without proper treatment, will lead to a series of environmental problems such as eutrophication of water bodies, deterioration of water quality, and biological death. In order to reduce the impact of wastewater on the environment, a series of treatment and purification measures are usually carried out on the wastewater to ensure that the concentration of pollutants is reduced, thereby reducing the potential harm to water bodies, soil and ecosystems. However, the existing wastewater treatment technologies and methods still have certain shortcomings when used.

[0003] An integrated industrial organic wastewater treatment equipment with announcement number CN205687712U is connected to the water inlet of the photocatalytic chamber through a main water pipe. A water pump is provided on the main water pipe. Multiple ultraviolet lamps, photocatalyst carriers and baffles are arranged in the photocatalytic chamber. The ultraviolet lamps, photocatalyst carriers and baffles correspond to each other to form an "S"-shaped channel. A water outlet is also provided at the lower end of the photocatalytic chamber. The process is simple, the installation and maintenance are convenient, the footprint is small, and the purification effect is good. However, the equipment takes a longer time to achieve the expected treatment effect when treating wastewater, which leads to a decrease in treatment efficiency, especially when treating large amounts of wastewater or high-concentration wastewater.

[0004] Therefore, a method and device for recovering and treating industrial organic waste liquid are proposed to solve the above-mentioned problems. Summary of the invention

[0005] The purpose of the present invention is to provide an industrial organic waste liquid recovery treatment method and device, so as to solve the problem raised in the above background technology that the equipment on the market currently cannot achieve the expected treatment effect when treating wastewater, resulting in reduced treatment efficiency.

[0006] To achieve the above object, the present invention provides the following technical solution: an industrial organic waste liquid recovery and treatment method, wherein the wastewater treatment method is: S1: first collect the industrial organic waste liquid in a collection tank, adjust the temperature in the collection tank according to the characteristics of the waste liquid, and use a stirring device to stir the waste liquid in the collection tank at a low speed. After the stirring is completed, the waste liquid is preliminarily filtered through a filter screen, and the filtrate obtained is transported to a temporary storage tank through a pipeline; S2: The waste liquid in the temporary storage tank is transported to the neutralization tank. In the neutralization tank, the acidity regulator and the alkalinity regulator will add acid or alkali to adjust the pH value of the waste liquid according to the current pH value of the waste liquid, and at the same time, the stirring device is turned on to stir the waste liquid; S3: The waste liquid with adjusted pH value is transported to the sedimentation tank through a delivery pipe.

[0007] S4: The supernatant in the sedimentation tank is transported to the flocculation tank through a pipeline. By adding flocculants to the flocculation tank, the tiny suspended particles in the wastewater are aggregated into larger flocs. The remaining wastewater is further transferred to the sedimentation tank by a cyclone separator. In the sedimentation tank, the dissolved oxygen content in the water is increased by aerating the wastewater. S5: The waste liquid after aeration and sedimentation is transported to the ultrasonic treatment tank, and the high temperature and high pressure environment and strong mechanical vibration generated by the ultrasonic cavitation effect are used to break the chemical bonds of the macromolecular organic matter that is difficult to degrade in the waste liquid and decompose it into small molecular organic matter; S6: transporting the waste liquid after ultrasonic pretreatment to a centrifugal tank for separation, and transporting the separated upper waste liquid to a reverse osmosis tank. In the reverse osmosis tank, the waste water is filtered through a reverse osmosis membrane to separate the waste liquid into a dilute liquid and a concentrated liquid, and the dilute liquid is discharged at the same time; S7: transporting the obtained concentrated solution to an oxidation pond, adding an oxidant to the oxidation pond, and stirring the concentrated solution and the oxidant to fully mix, and further oxidizing and decomposing the organic matter in the concentrated solution by the strong oxidizing property of the oxidant to obtain H2O, CO2 and N2 without pollutants; S8: Collect the substances produced in S1 to S3, and recycle them for further processing.
