Embodiment

[0021] In this example, the shell of the plasma reactor is made of plexiglass, with an inner diameter of 150mm, an outer diameter of 170mm, and a height of 400mm. The size of the sewage receiving tank is 200mm*200mm*200mm. The metal electrode adopts a special design, one end is closed and the other end is open. There are 5 layers of electrodes, each layer has 8 positive and negative electrodes, and the electrode spacing is 5-10mm. The peak voltage of the pulse power supply is 20-30kv, and the frequency is 200hz.

[0022] Select 2L of sewage brewed from the traditional Chinese medicine Chuanwu as the sewage sample, and conduct the effect experiment through the fast pulse discharge plasma equipment shown in the attached figure. The steps are as follows:

[0023] 1. Connect 2L of Chuanwu wastewater into the sewage receiving tank 2, turn on the water pump 3 to transport it to the top of the reactor, and spray it out from the atomizing nozzle 4.

[0024] 2. Turn on the fast pulse...

Abstract

The invention belongs to the technical field of wastewater treatment, and particularly relates to a device for removing toxicity in traditional Chinese medicine wastewater by plasma discharge. The device is mainly composed of a plasma reactor, a pulse power supply, a sewage receiving tank, am air pump and a water pump. Traditional Chinese medicine wastewater is pumped from a sewage tank to the top of the reactor by the water pump; the middle part is provided with a discharge electrode, and the bottom is provided with the sewage receiving tank. The discharge electrode is connected with the external pulse power supply, and is the core of the whole device. The outer wall of the reactor is connected to the ground, thereby ensuring the electric safety of the whole device. Meanwhile, the air pump connects the upper part of the reactor with the top of the sewage receiving tank, and the gas generated by discharge is recycled and connected to an aeration tank by the air pump and introduced into the sewage receiving tank, thereby further enhancing the treatment efficiency. The device can effectively remove toxic groups in the traditional Chinese medicine sewage, is beneficial to subsequent biochemical degradation of the traditional Chinese medicine sewage to finally achieve the discharge standard, and has the advantages of simple treatment method, low cost and high efficiency.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a device for removing the toxicity of traditional Chinese medicine wastewater by plasma discharge. Background technique [0002] In recent years, the use of traditional Chinese medicine has increased significantly. The wastewater produced by processing traditional Chinese medicine has certain toxicity. When it is biochemically treated with other wastewater, microorganisms will be killed, not only the traditional Chinese medicine wastewater cannot be treated, but other wastewater cannot be effectively degraded due to the elimination of microorganisms. , so it is particularly important to remove the toxicity of traditional Chinese medicine wastewater. Obviously, the traditional biochemical method can't play a role, and other physical and chemical methods can't get good results, the treatment cost is high and the effect is low, and it is difficult to obtain gen...
