Embodiment 1

[0032] see figure 1 , a special equipment for treating high-concentration organic wastewater by combined use of ozone and high-voltage corona, including a water storage tank 9 and a wastewater circulation system. , the special equipment also includes an ozone generator 3 and a high-voltage corona generator 4, and the waste water circulation system also includes a gas-liquid mixer 7, and the ozone generator 3 is connected to the gas-liquid mixer 7, so Corona discharge electrodes are installed in the water storage tank 9 described above, and the high-voltage corona generator 4 is connected to the corona discharge electrodes.

[0033] In described water storage tank 9, be provided with ozone corona enhanced reactor 5, described ozone corona enhanced reactor 5 comprises insulating tube and corona discharge electrode, and corona discharge electrode is installed on both sides of described insulating tube, The outlet pipe of the waste water circulation system is connected to one end...

Embodiment 2

[0038] refer to figure 1 , a method for treating high-concentration organic wastewater by combining ozone and high-voltage corona, said method is to treat wastewater simultaneously with ozone generator and high-voltage corona generator, comprising the following steps: (1), The waste water in the reservoir 9 is introduced into the waste water circulation system with the circulating water pump 8; (2), open the ozone generator 3 and the high-voltage corona generator 4 again, and the described ozone generator 3 is connected on the water pipe of the waste water circulation system, The high-voltage corona generator 4 is connected to the corona discharge electrodes located in the water storage tank.

[0039] The water inlet pipe and the water outlet pipe of the waste water circulation system extend into the water storage tank, and the outlet of the water outlet pipe is located between the corona discharge electrodes. In the above (1), the pH value of the wastewater is adjusted to 8-...

Embodiment 3

[0055] refer to figure 1 , In this embodiment, industrial pure oxygen is used instead. Industrial pure oxygen can be directly input into the ozone generator without freeze-drying, and the flow rate is adjusted according to the instructions. Other operations are the same as in Example 2.

[0056] See Table 2 for the implementation effect:

Abstract

A method for treating high-concentration organic wastewater by combining ozone and high-voltage corona, the method is to treat wastewater simultaneously with an ozone generator and a high-voltage corona generator, comprising the following steps: (1) The waste water in the waste water is introduced into the waste water circulation system with the circulating water pump; (2) open the ozone generator and the high-voltage corona generator again, and the described ozone generator is connected on the water pipe of the waste water circulation system, and the high-voltage corona generation The device is connected to the corona discharge electrodes located in the water storage tank. And treatment equipment consisting of ozone corona enhanced oxidation reactor, ozone generating unit, high voltage corona power supply and waste water circulation system. The invention provides a method and equipment for treating high-concentration organic wastewater by combining ozone and high-voltage corona with high utilization efficiency and good treatment effect.

Description

(1) Technical field [0001] The invention relates to a method and equipment for treating organic wastewater, especially suitable for treating organic wastewater with high concentration, small water volume and high toxicity. (2) Background technology [0002] Chemical and pharmaceutical companies have a large volume and a wide range. They are one of China's pillar industries and account for a large proportion of economic benefits and foreign exchange earnings from exports. However, chemical and pharmaceutical wastewater has the characteristics of high concentration, high toxicity, and high salt content. Traditional It is difficult to meet the standard discharge of waste water treatment method, which is one of the current environmental protection problems. There is no efficient and economical treatment method for this kind of wastewater, so it has caused serious pollution to the local environment and had a long-term impact on the local ecology. Where there are many chemical an...
