Abstract

The invention discloses a device and a method for treating wastewater with high content of salt and organic compounds by using an electromagnetic technique. Multiple stages of electromagnetic pole perforation plates are arranged in the device, wherein each electromagnetic pole perforation plate is formed by a plurality of electromagnetic units and magnetic water flow gaps through an alternate arrangement manner; two adjacent electromagnetic pole perforation plates and a magnetic water reaction area between the two electromagnetic pole perforation plates form a magnetic water reaction unit; the wastewater enters a water inlet area of the device through a water inlet pipe, passes through the magnetic water flow gaps from the water inlet area and enters the magnetic water reaction areas, so that the organic compounds in the wastewater can be rapidly degraded; after the wastewater is subjected to multi-stage magnetic water reaction, the wastewater enters a water outlet area and is discharged out of the device; ultrasonic generators are arranged at the bottom of the device, so that the degradation efficiency of the organic compounds is improved; aeration vent pipes are arranged at the upper ends of the ultrasonic generators; gases such as oxygen, ozone, nitrogen and the like can be introduced for carrying out collaborative electromagnetic treatment according to the water quality conditions of the inlet water. The device and the method have excellent effects on treating the wastewater with high content of salt and non-degradable organic compounds; the difficulty of subsequent treatment process can be reduced; the treatment cost can be reduced.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and energy saving, and specifically relates to a sewage treatment device and method capable of degrading refractory organic matter in sewage through magnetic field energy generated by electromagnetic field excitation, so that sewage can be more easily purified. Background technique [0002] With the rapid development of industrialization, the environmental problems caused by improper treatment of industrial wastewater have become one of the main environmental protection problems that we are currently facing. In the treatment of industrial wastewater, the treatment of high-salt and high-organic wastewater is a major problem in the treatment of industrial wastewater. Higher salinity and high concentrations of refractory organic matter are the difficulties in the treatment of this type of wastewater. If it is not treated before discharge, the high concentration of soluble inorganic s...
