Abstract

The invention discloses a plasma treatment system for synchronously removing organic matters and heavy metals and a treatment method thereof, and belongs to the technical field of wastewater treatment. The plasma treatment system comprises a reactor, a treatment pool and a peristaltic pump. A water distributor is fixed at the top of the reactor, a water inlet pipe is connected the inner cavity ofthe water distributor, and a water outlet pipe is connected on the bottom of the reactor; a water outlet of the water outlet pipe extends into the treatment tank, the treatment tank and one end of theperistaltic pump are connected with a connecting pipe, the other end of the peristaltic pump is connected with the water inlet pipe, a high-voltage electrode is fixed outside the reactor, and the high-voltage electrode is tightly attached to the outer wall of the outer pipe; a ground electrode is arranged in the reactor, and the high-voltage electrode and the ground electrode are connected with an external high-voltage high-frequency alternating-current power supply; by adopting the novel plasma reactor, the contact area between plasma and pollutants is larger, the discharge is more uniform and stable by adopting a new water distribution mode, the generated plasma can be used for uniformly treating the pollutants in the water body, and the treatment effect is obviously improved.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a plasma treatment system and a treatment method for synchronously removing organic matter and heavy metals. Background technique [0002] In recent years, with the rapid development of my country's economy, the discharge of industrial pollutants is also increasing day by day. Among them, a large amount of industrial wastewater produced by chemical industries such as electrolysis, electroplating, papermaking, and printing and dyeing has complex components. In addition to refractory organic matter, it also contains a large amount of heavy metals. For example, polycyclic aromatic hydrocarbons (PAHs), cyanide, phenols, chromium (Cr), uranium (U), zinc (Zn) and other organic substances and heavy metals were detected in electroplating wastewater, printing and dyeing wastewater, and oil refining wastewater. Degradation, it will exist in nature for a long time, and enrich ...
