High-voltage pulse electric sterilization process

Abstract

The invention belongs to the technical field of water treatment, and particularly relates to a high-voltage pulse electric sterilization process which comprises the following steps: pumping wastewater into a high-voltage pulse electric sterilization device through a water pump for sterilization treatment, and then discharging; wherein the high-voltage pulse sterilization device comprises a main body pipe, a left polar plate, a right polar plate, a water inlet pipe, a water outlet pipe, a left sealing plate and a right sealing plate, the left polar plate is arranged on the left side of the main body pipe through the left sealing plate, the right polar plate is arranged on the right side of the main body pipe through the right sealing plate, and the right polar plate is further connected with a screw; the water inlet pipe and the water outlet pipe are both connected with the main body pipe; the left pole plate and the right pole plate are connected with a power supply; compared with the prior art, the process has the advantages that the instantaneous change of voltage is utilized to generate irreversible loss on bacteria and further cause bacteria death, that is, the process utilizes the perforation effect of microbial cells caused by a strong current field to sterilize.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a high-voltage pulse electric sterilization process. Background technique [0002] The current general water treatment methods mainly include chemical methods such as chlorine disinfection, ozone treatment, and physical methods such as ultraviolet sterilization. The chlorine-based disinfection reagents used in the chlorine-based disinfection method are currently widely used in water treatment due to their strong oxidizing properties, low price, and easy storage and transportation. However, more toxic by-products are produced during water treatment, which is harmful to people. There are carcinogenic risks in health; the ozone treatment method will release strong oxidizing hydroxyl radicals during ozone hydrolysis to inactivate bacteria, but this gas is unstable and easy to cause harm to the human body, and the high disinfection cost also limits It is used on a...

The chlorine-based disinfection reagents used in the chlorine-based disinfection method are currently widely used in water treatment due to their strong oxidizing properties, low price, and easy storage and transportation. However, more toxic by-products are produced during water treatment, which is harmful to people. There are carcinogenic risks in health; the ozone treatment method will release strong oxidizing hydroxyl radicals during ozone hydrolysis to inactivate bacteria, but this gas is unstable and easy to cause harm to the human body, and the high disinfection cost also limits It is used on a large scale; ultraviolet sterilization technology has high requirements for water clarity in water treatment, and the disinfection ability is not durable, and the cost of equipment is relatively high
