Sweep frequency electromagnetic field generator

Abstract

The invention relates to a sweep electromagnetic field generator for generating a sweep electromagnetic field to treat sewage. The generator can simultaneously generate a direct-current electric field and a sweep pulse electromagnetic field for water treatment by the sweep frequency technique; frequency spectrum of the sweep pulse electromagnetic field generated by the generator can be changed continuously, thereby the generator is suitable for water to be treated with various characteristics; the sweep pulse electromagnetic field can make algae or bacterium cell molecules in water generate vibration, to cause the cell wall to break, and internal substances of cells accumulated together so as to make algae or bacteria dead, thereby achieving the aims of sterilization and algae removal; due to the electrolytic action of the direct-current electric field, a great deal of active substances can be generated in the water, for example, OH<->, ClO<->, H2O2, HClO and so on, thereby strengthening the effects of sterilization and algae removal; and moreover, the direct-current electric field and the sweep pulse electromagnetic field can generate electrochemical reaction and electrocoagulation action, so as to remove organic substances, heavy metal ions and suspended substances in the water, reduce the turbidity, the COD (the chemical oxygen demand) and the BOD (the biological oxygen demand) and so on.

Description

Technical field: [0001] The invention relates to a frequency-sweeping electromagnetic field generator, in particular to a frequency-sweeping electromagnetic field generator for generating a frequency-sweeping electromagnetic field for sewage treatment. Background technique: [0002] The use of electromagnetic fields to treat industrial and domestic water is a kind of physical water treatment. Its principle is to make water pass through electromagnetic fields, thereby breaking the bonding bonds of water in the state of large associations, and dissociating water into highly active single molecules or Water in a small association state, thereby changing the physical structure and characteristics of water, increasing the dipole moment of water molecules, changing the deposition state of sedimentary substances in water, and the physical properties of various ions, so as to effectively achieve scale prevention, scale removal, The purpose of sterilizing, algae killing, antirust and...

AI Technical Summary

Problems solved by technology

However, in actual application, because the industrial and domestic water to be treated have very different chemical and physical properties, the water treatment devices in the prior art have poor treatment effects.

Even if frequency conversion signals are used in some water treatment devices, the signal frequency only changes at some fixed or discrete points. Therefore, the distribution of the signal spectrum is too narrow for the water to be treated with complex changes in chemical and physical properties. , the processing effect is still unsatisfactory
