Water treatment process and equipment

Abstract

The invention relates to a method for dealing with water by adopting sweep-frequency technique and equipment thereof, which adopts sweep-frequency pulse electromagnetic field and direct current electric field to treat water simultaneously or in sequence by sweep-frequency technique. The sweep-frequency pulse electromagnetic field spectrum produced can change continuously and can be applied to the water in suspense with various properties; wherein, the sweep-frequency pulse electromagnetic field can facilitate the cellular elements of alga or microbe to generate libration, breakage of cell walls is aroused, the substances contained in cell accumulate together so as to arouse death of alga or microbe, and the effect of sterilization and killing alga is realized. And the electrolysis of the direct current electric field can generate much active substances in the water, such as OH<->, ClO<->, H2O2, HClO, and the like, and the effect of sterilization and killing alga can be enhanced. Additionally, direct current electric filed and the sweep-frequency pulse electromagnetic field can produce electrochemical reaction and electrocoagulation effect, thus removing organic matter and heavy metal ions in the water, lowering turbidity, removing suspended substance and lowering COD (chemical oxygen demand) and BOD (biological oxygen demand), etc.

Description

Technical field: [0001] The invention relates to a water treatment method and equipment, in particular to a water treatment method and equipment using a frequency-sweeping pulse electromagnetic field. 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 anticorrosion is to activate and clear the water qu...

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
