Industrial circulating water processing and production device and production method using the same

Abstract

The invention discloses an industrial circulating water processing and production device. The device comprises a water inlet pump, a membrane bioreactor, a circulating pump, a photocatalytic oxidation reactor, a magnetization sterilization reactor and a water outlet pump. The membrane bioreactor comprises a first membrane module and a second membrane module in the bioreactor. A water outlet end of the first membrane module is connected to a photocatalytic oxidation reactor through the circulating pump. A movable separation plate is arranged between the first membrane module and the second membrane module. A water outlet end of the photocatalytic oxidation reactor is connected to the magnetization sterilization reactor. A water outlet end of the magnetization sterilization reactor is connected to a water outlet pump through a first valve and is connected to the membrane bioreactor through a second valve. A water outlet end of the second membrane module is connected to the water outlet pump through a third valve. The invention also discloses a production method using the production device. The method and device realize fast and efficient purification of industrial circulating water and killing of bacteria in industrial circulating water, does not produce negative influence on the quality of industrial circulating water and is safe and environmentally friendly.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an industrial circulating water processing production device and a production method thereof. Background technique [0002] my country is a country with a shortage of water resources. The recycling and reuse of water resources is a very promising business. The recycling and reuse of water resources is to purify sewage and industrial sewage so that they can be reused. Save a lot of water resources. With the rapid development of my country's economy, my country's sewage discharge has increased year by year, including domestic sewage and industrial sewage. If it is discharged randomly, it will cause pollution of the groundwater body and lead to eutrophication. Therefore, there is an urgent need for a fast and efficient device and method to make this wastewater meet the requirements of the comprehensive sewage discharge standard. [0003] In the field of industrial circulating water ...

[0003] In the field of industrial circulating water purification and sterilization, chemical fungicides are basically used to prevent microorganisms from forming sticky scales and corroding heat exchangers and pipelines. Whether these chemical fungicides are oxidizing or non-oxidizing, if they are used The amount of addition is small, and the impact on the quality of circulating water may be basically negligible, but it cannot reach the bactericidal control index. In order to achieve the bactericidal index, the dosage must be large, which will inevitably have an adverse effect on the quality of circulating water. Some fungicides, If it is an oxidizing fungicide, it...
