Description
Technical Field
The invention relates to the technical field of organic wastewater treatment, in particular to a high-concentration organic wastewater pretreatment device.
Background
Iron-carbon microelectrolysis is a good process for treating wastewater by using a metal corrosion principle to form a galvanic cell, and is also called an internal electrolysis method, an iron scrap filtration method and the like. The micro-electrolysis technology is an ideal process for treating high-concentration organic wastewater, and is also called an internal electrolysis method. Under the condition of no power supply, the micro-electrolysis material filled in the wastewater generates a 1.2V potential difference to carry out electrolysis treatment on the wastewater so as to achieve the purpose of degrading organic pollutants.
In recent years, micro-electrolysis has been widely applied to wastewater treatment in many industries, and the process is mature. A large amount of nascent Fe2+ and nascent hydrogen radicals generated in the application have extremely high chemical activity, can change the structure and the characteristics of a plurality of organic matters in the wastewater, and lead the organic matters to have the functions of chain scission, ring opening and the like.
The iron-carbon micro-electrolysis equipment is characterized by simple structure and good plug flow property, but has a plurality of practical problems: firstly, the bed body is easy to harden, causing short circuit and dead zone; secondly, iron scrap supplement and high labor intensity of mixing are achieved; thirdly, the surface of the filler is easy to passivate. Blockage and hardening, which results in the affected treatment effect, and the iron carbon filler needs to be turned or replaced after a period of time. Need clear up equipment when changing, in the middle of adding carbon particle with iron fillings, after the misce bene, refill. After the iron chips are operated for a long time, the surfaces of the iron chips are corroded, and sludge-like residues generated by corrosion can be adhered to the surfaces of the iron chips and carbon particles, so that the iron-carbon contact is deteriorated, namely, the surfaces of the iron chips and the carbon particles are passivated, and the degradation effect is influenced.
The water flow adopted by the traditional iron-carbon micro-electrolysis device is horizontal flow or vertical flow. In the horizontal flow, the carbon is relatively light, so the floating is easy to occur; in the vertical flow, if upward flow is selected, the problem of hardening is easily overcome, but the upward flow also causes iron-carbon separation, so that the contact rate between iron and carbon is greatly reduced, and if downward flow is selected, hardening is easily caused.
Disclosure of Invention
