Problems solved by technology

[0007] (1) At present, the common ozone preparation technology uses air or pure oxygen as the raw material and adopts the corona discharge method. stay high
[0008] (2) The solubility of ozone in water is low, and the mass transfer effect of traditional contact equipment or methods (aeration) is not ideal, resulting in low absorption efficiency of gas-liquid contact, which limits the concentration of ozone participating in the reaction, thereby limiting the effect of pollutant treatment , the low ozone utilization rate exacerbates the cost disadvantage of ozone oxidation technology

Embodiment 1

[0063] refer to figure 1 , the present embodiment provides a micro-interface enhanced ultra-high-efficiency wastewater ozone treatment device, including: an ozone generator 170 and a reaction tower; a partition plate 60 is arranged in the middle of the reaction tower; a first treatment zone 180 is above the partition plate 60, Below is the second treatment area 10 . The side wall of the first treatment area 180 is connected with the wastewater pipeline 100; the first micro-interface unit is arranged in the first treatment area 180, and the second micro-interface unit is arranged in the second treatment area 10; the outlet of the ozone generator 170 is respectively connected with The first micro-interface unit is connected to the second micro-interface unit, and the inlet is connected with an oxygen pipeline 160. During the reaction, oxygen enters the ozone generator 170 through the oxygen pipeline 160 and reacts to generate ozone, and the ozone is respectively input into the f...

experiment example 1

[0079] Taking the waste water of a chemical enterprise as an example, the waste water was treated by the treatment devices of Embodiment 1, Comparative Example 1 and Comparative Example 2 respectively.

[0080] Among them, the waste water volume is 100m 3 / h, the COD is 2400mg / L, the ozone dosing concentration is 100mg / L, and the COD of the produced water at the liquid outlet is tested. The test results are shown in the table below.

[0081] Table 1 Test results

[0082] COD (mg / L) Removal rate (%) Example 1 40.8 98.3 Comparative example 1 331.2 86.2 Comparative example 2 156 93.5 Comparative example 3 105.6 95.6

[0083] It can be seen from Table 1 that the treatment device of this embodiment can effectively purify wastewater, and the removal rate can reach 98.3%. Wherein, the removal rate of comparative example 1 only reaches 86.2%, because there is only one treatment zone in comparative example 1, the part ozone that enters wh...

Abstract

The invention provides a micro-interface enhanced super-efficient wastewater ozone treatment device. The device comprises an ozone generator and a reaction tower; a partition plate is arranged in the middle of the reaction tower; a first treatment area is arranged above the partition plate, and a second treatment area is arranged below the partition plate; the side wall of the first treatment area is connected with a wastewater pipeline; a first micro-interface unit is arranged in the first processing area, and a second micro-interface unit is arranged in the second processing area; the inlet of the ozone generator is connected with an oxygen pipeline, and the outlet of the ozone generator is respectively connected with the first micro-interface unit and the second micro-interface unit; and an overflow pipe is arranged in the first treatment area and penetrates through the partition plate to be communicated with the first treatment area and the second treatment area. The micro-interface enhanced super-efficient wastewater ozone treatment device is simple in overall structure, the purification treatment effect on wastewater can be effectively improved, efficient utilization of ozone can be achieved, and therefore the wastewater treatment cost is reduced.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a micro-interface enhanced ultra-high-efficiency wastewater ozone treatment device and a treatment method. Background technique [0002] my country's water resources are short, and with the rapid development of industry, the types and quantities of wastewater are increasing rapidly, and the pollution of water bodies is becoming more and more extensive and serious. The water environment is facing an extremely severe situation, threatening human health and safety. Under such circumstances, the state has successively issued a series of policies and measures in recent years, such as the "Water Pollution Prevention and Control Action Plan", to vigorously carry out water environment improvement. The key to water environment governance and protection lies in wastewater treatment in the industrial field, and the key to industrial wastewater treatment lies in: 1) Source contr...
