Abstract

The invention discloses an industrial sewage treatment technique based on high-voltage nanosecond pulsed electric field technology. The technique comprises the following steps: 1. preliminary treatment: carrying out preliminary treatment on sewage to be treated by using microfiltration membrane technology in combination with coagulation and adsorption processes to remove suspended particles, fibers and bacteria in the sewage; and 2. high-voltage pulsed field treatment: atomizing the sewage subjected to microfiltration so that the water fog is positioned among multiple needle-board special-shaped electrodes, and applying high-voltage pulses among the electrodes to generate a high-voltage pulsed electric field so as to degrade organic substances in the water fog, thereby implementing sewage purification. The technical scheme does not need any additional oxidant; the reaction system does not need high temperature, high pressure, additional light source or any other auxiliary technical means; and thus, the technique is novel water treatment technology which integrates shock waves, optical, electric and chemical oxidation, and has the advantages of high efficiency and no secondary pollution. The invention also discloses a treatment system based on the method.

Description

technical field [0001] The invention relates to the technical field of sewage treatment and environmental treatment, in particular to an industrial sewage treatment process based on high-voltage nanosecond pulse electric field technology. Background technique [0002] Sewage treatment refers to the process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. [0003] According to the classification of sewage sources, sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Production sewage includes industrial sewage, agricultural sewage and medical sewage, etc., while domestic sewage is sewage produced in da...
