Problems solved by technology

Although the treatment of industrial wastewater started as early as the end of the 19th century, due to the complex composition and changeable nature of many industrial wastewater, there are still some technical problems that have not been completely resolved.
With more and more pollutants and refractory substances in industrial wastewater, the water quality is becoming more and more complex, and it is difficult for a single treatment process to meet the treatment requirements.
It is the general trend to combine one or more of physical, chemical, and biochemical methods as a treatment process. At present, there is no device system that can remove industrial wastewater with high efficiency, simple operation, easy control, and resource utilization.

Embodiment 1

[0024] Embodiment one: a kind of device that removes organic macromolecules in industrial wastewater, a kind of device that removes organic macromolecules in industrial wastewater, such as figure 1Shown: the device is composed of coagulation tank 1, filter 7, buffer tank 10, resin adsorption device 17, evaporative condensation device 28, cold trap 33, ozone oxidation column 42 and water storage tank 50 after oxidation through pipelines and valves The processing flow is connected sequentially. The resin adsorption device 17 is formed by parallel connection of two resin adsorption columns equipped with macroporous adsorption resin 19 inside each resin adsorption column. There are three layers of adsorption sieve plates 18 inside each resin adsorption column to divide the resin column into equal intervals. Three sections, the adsorption sieve plate 18 can filter out large particles of impurities, reduce the pressure of the resin column, and prevent resin agglomeration. Each adsorp...

Embodiment 2

[0034] Embodiment two: a kind of device that removes organic macromolecules in industrial waste water, such as figure 1 Shown: Pour the wastewater into the coagulation tank 1, add the coagulant and stir evenly with the stirring paddle 2, carry out coagulation treatment to make the large particles of impurities in the wastewater flocculate and settle down, the floating device 4 floats up and down according to the turbidity of the liquid, Let the relatively clear liquid flow into the filter 7 preferentially through the valve 3, and the relatively turbid liquid flow into the filter 7 through the valve 5, open the valve 8 and use the vacuum pump 9 to quickly filter the waste water in the filter into the buffer tank 10, open the valve 11 And the valve 15 pumps the water in the buffer tank 10 into the two parallel resin adsorption columns 17 at the same time through the water pump 12, and uses the flow meter 14 to control the flow rate so that the waste liquid passes through the two ...

Embodiment 3

[0036] Embodiment three: a kind of device that removes organic macromolecules in industrial waste water, such as figure 1Shown: Pour the wastewater into the coagulation tank 1, add the coagulant and stir evenly with the stirring paddle 2, carry out coagulation treatment to make the large particles of impurities in the wastewater flocculate and settle down, the floating device 4 floats up and down according to the turbidity of the liquid, Let the relatively clear liquid flow into the filter 7 preferentially through the valve 3, and the relatively turbid liquid flow into the filter 7 through the valve 5, open the valve 8 and use the vacuum pump 9 to quickly filter the waste water in the filter into the buffer tank 10, open the valve 11 And the valve 15 pumps the water in the buffer tank 10 into the two parallel resin adsorption columns 17 at the same time through the water pump 12, and uses the flow meter 14 to control the flow rate so that the waste liquid passes through the two...

Abstract

The invention relates to an environmental protection technique and wastewater treatment technique device, in particular to a device for removing organic macromolecules in industrial wastewater. A coagulation tank, a filter, a buffer tank, a resin adsorption device, an evaporation condensation device, a cold trap, an ozone oxidization column and a post-oxidation water storage tank which are sequentially connected through a pipeline and a valve along a treatment procedure to form the device. The device is unique in structure, simple to operate, easy to control, simple in process procedure and high in treatment efficiency, resource utilization can be achieved, a resin adsorption process and a ozone oxidization process are combined to synergistically treat the organic macromolecules in the industrial wastewater, cost is saved, energy consumption is reduced, industrial wastewater is discharged after reaching the standard, and the device has a wide application prospect.

Description

technical field [0001] The invention relates to a device for environmental protection technology and waste water treatment technology, in particular to a device for removing organic macromolecules in industrial waste water. Background technique [0002] Industrial wastewater refers to the wastewater and waste liquid discharged during the process of production, which contains industrial production materials, intermediate products, by-products and pollutants generated in the production process that are lost with water. It is an important cause of environmental pollution, especially water pollution. reason. Although the treatment of industrial wastewater started as early as the end of the 19th century, due to the complex composition and changeable nature of many industrial wastewater, there are still some technical problems that have not been completely resolved. With the increasing amount of pollutants and refractory substances in industrial wastewater, the water quality is b...
