Abstract

The invention provides a treatment method and a treatment device for increasing BOD in smoothing liquid wastewater. The treatment method includes the following steps: the smoothing liquid wastewater flows into a cylindrical filter, and then enters the fiber filter through a first-level water inlet pump. The fiber filter has a built-in spray filter element; the flat wastewater enters the intermediate water tank after passing through the fiber filter, and then enters the photochemical reactor through the secondary water inlet pump; the outside of the photochemical reactor is composed of a transparent quartz glass tube with a built-in solid-supported photocatalyst. The solid-supported photocatalyst is a glass fiber-supported titanium sulfur vanadium photocatalyst; after passing through the photochemical reactor, it finally enters the biochemical tank for aerobic biochemical treatment. The treatment system and method of the present invention have low one-time investment, simple operation and low production and treatment costs, and are an environmentally friendly green steel wastewater treatment process.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a treatment method and a treatment device for improving BOD in leveling liquid wastewater. Background technique [0002] Leveling liquid is an important medium used in the steel wet leveling process. Leveling liquid generally consists of the following parts: rust remover, surfactant, lubricant, defoamer and deionized water, etc. [0003] The pH of the leveling liquid wastewater produced in the wet leveling process is 9-10, the conductivity is 400-4000us / cm, the BOD is 95-260mg / L, and the suspended matter is 25-60mg / L. Leveling liquid has many organic pollutants, low BOD (biochemical oxygen demand), and poor biodegradability. Traditional biological treatment is difficult to work. At present, there is no mature treatment process at home and abroad. Most of it is diluted and mixed with other wastewater. It is one of the most difficult steel industry wastewater ...
